Is shoulder pain for three months or longer correlated with depression, anxiety, and sleep disturbance?

Rotator cuff repair: Sleep disturbance significantly improves after arthroscopic tendon repair

PURPOSE

The aim of this study was to quantify sleep quality and define its evolution in patients treated for rotator cuff tears (RCTs) with arthroscopic rotator cuff repair (ARCR) and to understand its correlation with patients' depression and anxiety.

METHODS

The patients were part of the 'ARCR_Pred cohort study', a prospective multicentre cohort of ARCR patients.

INCLUSION CRITERIA

adult, RCT diagnosed by magnetic resonance imaging, treated by primary ARCR.

EXCLUSION CRITERIA

irreparable tears, revision operations, open or mini-open reconstructions, pregnancy. Subjective sleep quality (prevalence and level of disturbance) was analysed. Psychological characteristics (PROMIS Sf questionnaire) and functional outcomes (Constant and Murley Score and Oxford Shoulder Score) were investigated. A gender-based analysis was performed as well. Patients were evaluated before the operation and prospectively at 6 and 12 months.

RESULTS

Of the 973 patients, 611 (62.8%) were men, with the mean age being 57.3 ± 9.4 years (range, 21-84). A high prevalence of sleep disturbances was found before ARCR (88.4%), with 59% of the patients complaining of disturbance every night. Sleep disturbances progressively improved at 6 (37.2%) and 12 months (22.0%). Also, nocturnal pain (frequency of night disturbed by pain) progressively improved from 94.3% to 62.4% and then 37.9%. For depression and anxiety, a statistically significant difference (p < 0.05) was retrieved among every group (undisturbed, occasionally and always disturbed) at all follow-ups. On the other hand, the post-op improvement led to a decrease in anxiety and depression levels passing from 50.1 and 51.4 points at baseline to 45.0 and 45.4 at 12 months, respectively. Women had statistically worse sleep quality at 6 and 12 months (41% vs. 36% and 27% vs. 19%, respectively) (p < 0.05).

CONCLUSIONS

RCTs cause a high prevalence of sleep disturbance and nocturnal pain, which progressively resolves after an arthroscopic tendon repair. Women have a higher risk than men of presenting disturbed sleep quality.

Psychosocial Factors, Sleep, and Central Pain Processing for Making a Prognosis About Recovery of Pain, Function, and Quality of Life After Rotator Cuff Repair: An Exploratory Longitudinal Study

OBJECTIVE: To explore modifiable psychosocial factors, sleep-related variables, indices of central pain processing and patients' characteristics as potential prognostic factors for pain, shoulder function, and quality of life (QoL) 1 year after rotator cuff repair. DESIGN: This observational longitudinal study included 142 patients who were undergoing rotator cuff repair. All measures took place pre-rotator cuff repair (T0), and 12 weeks (T1) and 12 months (T2) after rotator cuff repair. METHODS: Mixed-effects linear regression modeled relationships between the Western Ontario Rotator Cuff Index (WORC, model A), the Subjective Shoulder Value (SSV, model B), and EuroQol's EQ-5D-5L for QoL (model C), and potential prognostic factors over time. Factors included psychosocial variables, sleep-related indices, and proxies of central pain processing. Patients' age, sex, and body mass index complemented the analyses. RESULTS: At follow-up (T2), data from 124 participants were available for analysis. Five prognostic factors were identified for the 1-year outcome. Better expectations for symptom reduction (P<.0001, -1.4 mm) and an increase in Douleur Neuropathique 4 score (P = .0481, -0.9 mm) affected the evolution of WORC over time (model A). An increase in injury perception subscale consequence (P = .0035, 0.04%) influenced the SSV trajectory (model B). In addition, when sleep quality (P = .0011, -0.13%) and sleep efficiency (P = .0002, 0.005%) improved, the EQ-5D-5L slope was affected (model C). CONCLUSION: Addressing cognitions, pain mechanisms and sleep behavior prior to rotator cuff repair can identify people who are at risk of a poor outcome after surgery.

A synthetic peptide exerts nontolerance-forming antihyperalgesic and antidepressant effects in mice

Chronic pain is a prevalent and persistent ailment that affects individuals worldwide. Conventional medications employed in the treatment of chronic pain typically demonstrate limited analgesic effectiveness and frequently give rise to debilitating side effects, such as tolerance and addiction, thereby diminishing patient compliance with medication. Consequently, there is an urgent need for the development of efficacious novel analgesics and innovative methodologies to address chronic pain. Recently, a growing body of evidence has suggested that multireceptor ligands targeting opioid receptors (ORs) are favorable for improving analgesic efficacy, decreasing the risk of adverse effects, and occasionally yielding additional advantages. In this study, the intrathecal injection of a recently developed peptide (VYWEMEDKN) at nanomolar concentrations decreased pain sensitivity in naïve mice and effectively reduced pain-related behaviors in nociceptive pain model mice with minimal opioid-related side effects. Importantly, the compound exerted significant rapid-acting antidepressant effects in both the forced swim test and tail suspension test. It is possible that the rapid antihyperalgesic and antidepressant effects of the peptide are mediated through the OR pathway. Overall, this peptide could both effectively provide pain relief and alleviate depression with fewer side effects, suggesting that it is a potential agent for chronic pain and depression comorbidities from the perspective of pharmaceutical development.

The influence of depression on clinical outcomes of total shoulder arthroplasty: a systematic Review

PURPOSE

Much of the current literature on total shoulder arthroplasty (TSA) has assessed the impact of preoperative medical comorbidities on postoperative clinical outcomes. The literature concerning the impact of psychological disorders such as depression on TSA has increased in popularity in recent years, but there lacks a thorough review of the influence of depression on postoperative pain and functional outcomes.

METHODS

We queried PubMed/MEDLINE and identified six clinical studies that evaluated the influence of a psychiatric diagnosis of depression on patient outcomes after TSA. Studies that discussed the impacts of depression on TSA, including PROs or adverse events in adults, were included. Studies focused on other psychologic pathology, non-TSA shoulder treatments, or TSA not for primary osteoarthritis were excluded. Non-clinical studies, systematic reviews, letters to the editor, commentaries, dissertations, books, and book chapters were excluded.

RESULTS

Three cohort studies described patient-reported pain and functional outcomes and three database studies assessed the risk of postoperative complications. Cohort studies demonstrated that the prevalence of depression in patients undergoing TSA decreased from preoperatively to 12-months postoperatively. Two studies demonstrated that depression is an independent predictor of less pre- to postoperative improvement in the ASES score at minimum 2-year follow-up; however, one study found the difference between patients with and without depression did not exceed the minimum clinically important difference. Database studies demonstrated that depression was associated with higher rates of blood transfusion (n = 1, OR = 1.8), anemia (n = 1, OR = 1.65), wound infection (n = 2, OR = 1.41-2.09), prosthetic revision (n = 1, OR = 1.92), and length of hospital stay (n = 3, LOS = 2.5-3 days).

CONCLUSION

Although patients with a preoperative diagnosis of depression undergoing TSA can achieve satisfactory relief of shoulder pain and restoration of function, they may experience poorer patient-reported outcomes and a higher risk of postoperative adverse events compared to their peers. Surgeons should be cognizant of the influence of depression in their patients to facilitate proper patient selection that maximizes patient satisfaction, function, and minimizes the risk of adverse events following TSA.

Improvements in Sleep After Shoulder Arthroscopy Are Correlated With Improvements in Various Patient-Reported Outcomes: A Systematic Review

Purpose

To determine the prevalence of sleep disturbances in patients before and after arthroscopic surgery of the shoulder and to evaluate the association between patient-reported outcomes and standardized sleep disturbance tools after shoulder arthroscopy.

Methods

A systematic review, following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines, was conducted by searching the PubMed, Embase, and Scopus databases using the terms "arthroscopic surgery" and "sleep." Two independent reviewers evaluated the studies based on the inclusion criteria focused on the effects of shoulder arthroscopy on sleep disturbance and the use of outcome measures related to sleep. Data on sleep quality and functional outcomes were collected and analyzed using various assessment tools, including the Pittsburgh Sleep Quality Index and American Shoulder and Elbow Surgeons score. The methodologic quality of included studies was assessed using the Methodological Index for Non-randomized Studies (MINORS) criteria.

Results

The review included 15 studies (9 Level IV, 5 Level III, and 1 Level II) comprising 1,818 arthroscopic patients (average age, 57.4 ± 8.86 years; follow-up range, 6 months to 75.7 months). The prevalence rates of sleep disturbances before and after shoulder arthroscopy ranged from 75.8% to 100% and from 19% to 62%, respectively. Every study included in this analysis reported an improvement in rates of sleep disturbances postoperatively compared with preoperatively. Improvements in standardized sleep disturbance scores were associated with functional outcomes.

Conclusions

Sleep disturbances are commonly observed before and after arthroscopic surgery of the shoulder. Arthroscopic surgery of the shoulder appears to improve sleep quality, and surgeons can expect functional outcomes, specifically the American Shoulder and Elbow Surgeons score, Simple Shoulder Test score, numeric rating scale or visual analog scale score, and Constant-Murley score, to improve in line with sleep quality.

The effect of cuff arthropathy stage on sleep disturbance and kinesiophobia in reverse shoulder arthroplasty patients

BACKGROUND

The current study aimed to determine the changes in pre-and post-operative Pittsburg sleep quality index (PSQI) and Tampa scale of kinesiophobia (TSK) values ​​according to the Hamada classification in patients who underwent reverse shoulder arthroplasty (RSA) for rotator cuff tear arthropathy (RCTA).

METHODS

One hundred and eight patients who underwent RSA for RCTA were reviewed retrospectively. The patients were divided into two groups with low grade (stages 1-2-3) (n = 49) and high grade (stages 4a-4b-5) (n = 59) according to the Hamada classification, which is the radiographic evaluation of RCTA. PSQI and TSK values ​​were calculated preoperatively, and post-operatively at the 6th week, 6th month, and 1st year. The change in PSQI and TSK values ​​between the evaluations and the effect of staging according to the Hamada classification on this change was examined.

RESULTS

When compared in preoperative evaluations, PSQI and TSK scores were found to be lower in low-grade group 1 (7.39 ± 1.56, 51.88 ± 4.62, respectively) than in high-grade group 2 (10.47 ± 2.39, 57.05 ± 3.25, respectively) according to Hamada classification (both p < 0.001). In the postoperative evaluations, PSQI and TSK results decreased gradually compared to the preoperative evaluations, and there was a severe decrease in both parameters between the 6th-week and 6th-month evaluations (both p < 0.001). Preoperatively, 102 (95%) patients had sleep disturbance (PSQI ≥ 6), and 108 (100%) patients had high kinesiophobia (TSK > 37). In the 1st year follow-ups, sleep disturbance was observed in 5 (5%) patients and kinesiophobia in 1 (1%) patient. When the Hamada stages were compared, it was seen that there was a significant difference before the operation (both p < 0.001), but the statistically significant difference disappeared in the PSQI value in the 1st year (p = 0.092) and in the TSK value in the 6th month (p = 0.164) post-operatively. It was observed that Hamada staging caused significant differences in PSQI and TSK values ​​in the preoperative period but did not affect the clinical results after treatment.

CONCLUSIONS

RSA performed based on RCTA improves sleep quality and reduces kinesiophobia. RCTA stage negatively affects PSQI and TSK before the operation but does not show any effect after the treatment.

Changes in serum levels of pain mediators in hemiplegic shoulder pain

OBJECTIVE

To provide a new insight into the diagnosis and treatment of hemiplegic shoulder pain (HSP) by investigating changes in serum pain mediators.

DESIGN

Cross-sectional study.

SUBJECTS/PATIENTS

Shoulder pain group (n = 34) and control group (n = 21).

METHODS

Pain-free shoulder mobility, anxiety status, depression status, and shoulder pain were measured by passive range of motion (PROM), self-rating anxiety scale, self-rating depression scale (SDS), and visual analog scale, respectively. The enzyme-linked immunosorbent assay was used to test the serum pain mediators, including interleukin (IL)-1β, IL-2, IL-6, IL-10, nerve growth factor (NGF), tumor necrosis factor-α (TNF-α), substance P (SP), calcitonin gene-related peptide (CGRP), bradykinin (BK), 5-hydroxytryptamine (5-HT), prostaglandin E2 (PGE2), and lysophosphatidic acid (LPA).

RESULTS

Shoulder pain group pain-free PROM significantly lower than control (p < .01), and SDS index score of shoulder pain group was significantly higher than control (p < .05). The rate of spasticity in the flexor elbow muscles is higher in shoulder pain group (p < .01). CGRP, IL-10, and IL-2 were significantly upregulated in shoulder pain group compared with control (p < .01), whereas NGF, TNF-α, IL-6, 5-HT, PGE2, SP, LPA, BK, and IL-1β were significantly decreased (p < .01).

CONCLUSION

Patients with HSP have a higher risk of joint mobility disorders and depression; spasticity may be an important factor in the development of shoulder pain; CGRP is thought to be the major pain mediator in HSP, and HSP may not be inflammatory.

Testing the association between shoulder pain prevalence and occupational, physical activity, and mental health factors in two generations of Australian adults

BACKGROUND

Shoulder pain is common among the adult population, but it appears to reduce in prevalence around retirement age. Associations between shoulder pain and work-place exposures, physical activity, or mental health status are unclear and may change with age. This study aimed to determine the prevalence of self-reported shoulder pain in Australian adults across two generations and test the association with occupational factors, physical activity, and mental health.

METHODS

In this cross-sectional study we used data from a longitudinal Australian pregnancy cohort (the Raine Study). We analysed data from the children (Gen2) at the 22-year follow-up (N = 1128) and parents (Gen1) at the 26-year follow-up (N = 1098). Data were collected on self-reported shoulder pain, occupational factors (employment status and work description), physical activity, and mental health at the respective follow-ups. Prevalence rates were provided as percentages with 95% confidence intervals. Univariate analysis for group comparisons included chi squared for categorical comparisons. The association of predictor variables and shoulder pain was assessed using logistical regression.

RESULTS

In Gen1 31.4% of adults aged 40-80 reported the presence of shoulder pain in the last month, with no significant difference between females and males. Gen1 participants younger than 65 reported more shoulder pain (OR[95%CI] = 1.80 [1.04-3.09]). Gen2 females (14.7%) reported shoulder pain in either shoulder more frequently than males (7.7%) and bilateral shoulder pain (8.0%) more frequently than males (1.9%). Gen1 had increased odds of reporting shoulder pain if their work was "physical or heavy manual" compared to "sedentary" (OR [95% CI] = 1.659 [1.185-2.323]) and when categorised with depression (OR [95% CI] = 1.940 [1.386-2.715]) or anxiety (OR [95% CI] = 1.977 [1.368-2.857]). Gen2 participants with depression (OR [95% CI] = 2.356 [1.620-3.427]) or anxiety (OR [95% CI] = 2.003 [1.359-2.952]) reported more shoulder pain.

CONCLUSION

Overall, shoulder pain was more prevalent in young females than males and was more prevalent in those under the age of 65. Cross-sectional associations were established between some occupational factors in older adults and depression in all adults, and shoulder pain.

Improvement in Sleep Disturbance Following Anatomic and Reverse Shoulder Arthroplasty

BACKGROUND

Sleep disturbance is commonly reported by patients with arthritis and rotator cuff disease. Small cohort studies have demonstrated sleep improvements following anatomic total shoulder arthroplasty (TSA) and reverse shoulder arthroplasty (RSA). However, to our knowledge, no large cohort study has evaluated sleep improvement after shoulder arthroplasty. The purpose of the present study was to determine the effects of shoulder arthroplasty on sleep improvement, including the speed of sleep recovery, improvement plateaus, and any differences observed between TSA and RSA.

METHODS

A retrospective analysis of our institution's shoulder and elbow repository evaluated patients who had been managed with TSA and RSA between 2012 and 2021. Our analysis focused on visual analog scale (VAS) pain scores as well as specific sleep-related questions included in the Simple Shoulder Test (SST) and American Shoulder and Elbow Surgeons (ASES) questionnaires. Preoperative characteristics were compared, and comparisons at the 3-month, 6-month, 1-year, and most recent follow-ups were performed to evaluate the efficacy of improvement, speed of recovery, improvement plateaus, and differences among implant types.

RESULTS

Our search identified 1,405 patients who were treated with shoulder arthroplasty, including 698 who underwent TSA and 707 who underwent RSA. Six hundred and seventy-six (97%) of those who underwent TSA and 670 (95%) of those who underwent RSA reported sleep disturbance prior to surgery and were eligible for inclusion. With the exclusion of 357 patients without complete follow-up, 989 patients (517 who underwent TSA and 472 who underwent RSA) met the inclusion criteria, with a median follow-up of 36 months for the TSA group and 25 months for the RSA group. Postoperatively, significant improvements in the ability to sleep comfortably and sleep on the affected side were observed in both the TSA group and the RSA group (p < 0.001). The ability to sleep comfortably returned faster than the ability to sleep on the affected side, with the ability to sleep comfortably reaching a plateau at 3 months and the ability to sleep on the affected side reaching a plateau at 6 months. Despite improvements in terms of sleep disturbance, at the time of most recent follow-up, 13.2% of patients in the TSA group and 16.0% of those in the RSA group could not sleep comfortably and 31.4% of those in the TSA group and 36.8% of those in the RSA group could not sleep on the operative side.

CONCLUSIONS

The results of the study demonstrated that both TSA and RSA provide significant and rapid improvement in patients' ability to sleep comfortably and, to a lesser extent, improves their ability to sleep on their affected side.

Efficacy of combined strategies of physical activity, diet and sleep disorders as treatment in patients with chronic shoulder pain. A systematic review

Introduction: The objective of this systematic review was to analyze the existing scientific evidence on the influence of dietary strategies, exercise, and sleep disorders on the symptomatology of patients with chronic shoulder pain, as well as to assess the methodological quality of the literature collected. Methods: The selection criteria were as follows: we included randomized controlled clinical trials written in English that investigated the effects of such interventions in patients with chronic shoulder pain and excluded studies where pre-operative rehabilitation or rehabilitation combined with corticosteroid injections was performed. We searched six databases Pubmed, Cochrane Library, Web of Science, CINAHL, Sportdiscus and Scopus, using the keywords "shoulder pain," "fasting," "physical therapy modalities," "rehabilitation," "exercise," "circadian clocks," and "chronic pain" to select randomized controlled clinical trials conducted in humans and written in English. The last search was conducted on 24/01/2023. (PROSPERO:CRD42023379925). Results: We used the tool proposed by the Cochrane Handbook to assess the risk of bias in the included studies of the 17 studies included, nine had a high risk of bias, two studies had an unclear risk of bias, and the remaining six studies had a low risk of bias. A total of 17 articles were selected, including 10 studies that showed a positive influences of exercise on chronic shoulder pain and five studies that showed a negative influence of sleep disorders on this patient profile. The remaining two articles analyzed the influence of nutritional strategies and metabolic problems in patients with chronic shoulder pain. The total sample size of the 17 included articles amounted to 9,991 individuals. Discussion: Studies confirm that exercise generates a hypoalgesic effect that improves chronic shoulder pain, functionality, and quality of life. Although dietary strategies and sleep disorders are known to influence chronic shoulder pain, there is a lack of studies that conduct interventions on these problems to assess how chronic shoulder pain varies.

Central sensitization syndrome in patients with rotator cuff tear: prevalence and associated factors

INTRODUCTION

A significant number of rotator cuff tear (RCT) patients developed chronic shoulder pain that did not correspond to physiological changes. Central sensitization syndrome (CSS) is a neurophysiological adaptation process that can result in hypersensitivity to peripheral stimuli. Although there is evidence of an association between CSS and musculoskeletal problems, no studies have focused on the association between CSS and RCT. The primary purpose of this study was to examine the prevalence of CSS in patients with RCT. The secondary purpose was to document the associated conditions and comorbidity that were associated with the CSS.

METHODS

This was a cross-sectional study of patients with RCT who completed the Central Sensitization Inventory (CSI). Patients with score of ≥ 40/100 were considered positive for CSS. Demographic and clinical data and CSI results were collected to analyze the prevalence and associated factors of CSS in RCT patients.

RESULTS

A total of 404 RCT patients were included, and the CSS prevalence was 39.4%. Compared to the non-CSS group, the CSS group had an odds ratio of 4.13 (95% CI, 2.70-6.32; p＜0.001) for ages 51-60, 3.07 (95% CI, 2.00-4.69; p＜0.001) for symptoms lasting more than 6 months, 6.08 (95% CI, 3.90-9.47; p＜0.001) for nonphysical laborers, 3.69 (95%CI, 2.42-5.61; p＜0.001) for long head of biceps (LHB) abnormality, 2.93 (95% CI, 1.93-4.45; p＜0.001) for concurrent shoulder stiffness, 4.82 (95% CI, 2.55-9.10; p＜0.001) for anxiety or panic episodes, and 2.11 (95% CI, 1.12, 4.00; p＜0.001) for depression.

CONCLUSIONS

The prevalence of CSS in patients with RCT was relatively high at 39.4%. The CSS was associated with higher age, female gender, and clinical findings of symptoms lasting over six months, nonphysical laborers, abnormal LHB, concurrent shoulder stiffness, anxiety, and depression.

One-year patient-reported outcomes following primary arthroscopic rotator cuff repair vary little by surgeon

Background

This study's purpose was to investigate the extent to which differences among operating surgeons may influence 1-year patient-reported outcome measures (PROMs) in patients undergoing rotator cuff repair (RCR) surgery, after controlling for general and disease-specific patient factors. We hypothesized that surgeon would be additionally associated with 1-year PROMs, specifically the baseline to 1-year improvement in Penn Shoulder Score (PSS).

Methods

We used mixed multivariable statistical modeling to assess the influence of surgeon (and alternatively surgical case volume) on 1-year PSS improvement in patients undergoing RCR at a single health system in 2018, controlling for eight patient- and six disease-specific preoperative factors as possible confounders. Contributions of predictors to explaining variation in 1-year PSS improvement were measured and compared using Akaike's Information Criterion.

Results

518 cases performed by 28 surgeons met inclusion criteria, with median (quartiles) baseline PSS of 41.9 (31.9, 53.9) and 1-year PSS improvement of 42 (29.1, 55.3) points. Contrary to expectation, surgeon and surgical case volume were neither statistically significantly nor clinically meaningfully associated with 1-year PSS improvement. Baseline PSS and mental health status (VR-12 MCS) were the dominant and only statistically significant predictors of 1-year PSS improvement, with lower baseline PSS and higher VR-12 MCS predicting larger 1-year PSS improvement.

Conclusion

Patients generally reported excellent 1-year outcomes following primary RCR. This study did not find evidence that the individual surgeon or surgeon case volume influences 1-year PROMs, independently of case-mix factors, following primary RCR in a large employed hospital system.

Is there an association between sleep quality and magnitude of capability?

PURPOSE

Given the stigma surrounding mental health, a discussion of how symptoms interfere with sleep might be a useful first step to identify unhelpful thoughts or feelings of distress. We asked: 1) Does sleep quality have an association with magnitude of incapability and pain intensity independent of mental health? and 2) Are mental health factors associated with sleep quality?

METHODS

We performed a cross-sectional study of one hundred and fifty-four patients seeking musculoskeletal care who completed measures of magnitude of capability, pain intensity, unhelpful thoughts regarding symptoms (catastrophic thinking, negative pain thoughts), distress (symptoms of anxiety and depression), and sleep disturbance. We tested factors associated with the magnitude of capability and pain intensity, accounting for sleep quality and mental health in multivariable models.

RESULTS

Accounting for potential confounding in multivariable analysis, lower magnitude of capability was independently associated with greater sleep disturbance, more unhelpful thoughts about symptoms (negative pain thoughts), and older age. Greater pain intensity was independently associated with greater unhelpful thoughts about symptoms (catastrophic thinking) and not using of an electronic device before bed. Greater sleep disturbance was independently associated with use of sleep medication, greater symptoms of anxiety, and greater unhelpful thoughts regarding symptoms (PCS).

CONCLUSION

Given the observation that sleep disturbance is associated with feelings of anxiety, clinicians can consider starting mental health discussions by focusing on sleep quality. App and web-based cognitive behavioral therapy-based treatments for sleep are readily available and have the potential to improve mental health.

Exercise for rotator cuff tendinopathy: Proposed mechanisms of recovery

Rotator cuff (RC) tendinopathy is a common recurrent cause of shoulder pain, and resistance exercise is the first-line recommended intervention. Proposed causal mechanisms of resistance exercise for patients with RC tendinopathy consist of four domains: tendon structure, neuromuscular factors, pain and sensorimotor processing, and psychosocial factors. Tendon structure plays a role in RC tendinopathy, with decreased stiffness, increased thickness, and collagen disorganization. Neuromuscular performance deficits of altered kinematics, muscle activation, and force are present in RC tendinopathy, but advanced methods of assessing muscle performance are needed to fully assess these factors. Psychological factors of depression, anxiety, pain catastrophizing, treatment expectations, and self-efficacy are present and predict patient-reported outcomes. Central nervous system dysfunctions also exist, specifically altered pain and sensorimotor processing. Resisted exercise may normalize these factors, but limited evidence exists to explain the relationship of the four proposed domains to trajectory of recovery and defining persistent deficits limiting outcomes. Clinicians and researchers can use this model to understand how exercise mediates change in patient outcomes, develop subgroups to deliver patient-specific approach for treatment and define metrics to track recovery over time. Supporting evidence is limited, indicating the need for future studies characterizing mechanisms of recovery with exercise for RC tendinopathy.

Anxiety and Depressive Symptoms Correlated to Patient-Reported Outcome Measures after Rotator Cuff Repair: A Prospective Study in the Perioperative Period

Anxiety and depressive symptoms adversely affect surgical outcomes in patients with rotator cuff tear (RCT) undergoing surgical repair. Patients without a diagnosis of mood disorders, such as anxiety and depression, before rotator cuff repair (RCR) can be considered an optimal candidate for surgery. The objective of this prospective observational study was to evaluate the relationship between anxiety and depressive symptoms, using the Hospital Anxiety and Depression Scale (HADS) as an assessment tool, and patient-reported outcome measures in RCT after repair surgery. This study included patients with RCT undergoing arthroscopic rotator cuff repair (RCR). Forty-three patients were included who had completed the HADS, Constant Murley Score (CMS), and Short Form Health Survey 36 (SF-36) questionnaires before surgery and in the postoperative follow-up, at 1 month, 3 months, and 6 months. The Friedman test showed that there were statistically significant changes in the different times point for HADS (p < 0.001), anxiety subscale of HADS, i.e., HADS-A (p < 0.001), depression subscale of HADS, i.e., HADS-D (p < 0.001), CMS (p < 0.001), and SF-36 (p < 0.001). The average scores of HADS, HADS-A, and HADS-D improved at each follow-up, showing improvement in discomfort. From the third month after surgery, there was an improvement in anxiety and depression disorders related to improved quality of life, functionality, and pain perception. The trend remained stable until the sixth month of follow up. This study shows that anxiety and depressive symptoms in RCT patients are significantly reduced after RCR with subsequent important improvements in terms of functionality, ability to carry out activities of daily living, perceived pain, and quality of life.

Association of Anxiety and Depressive Symptoms in Patients with Adhesive Capsulitis

Objective  The present study aimed to assess the association between anxiety and depression symptoms in patients with adhesive capsulitis. Methods  This was a cross-sectional study carried out in a single center from a tertiary hospital with patients presenting with secondary adhesive capsulitis. The control group did not have shoulder disease, thyroid disease, anxiety, and/or depression. The instrument used was the Hospital Anxiety and Depression Scale (HADS). An analysis of covariance compared HADS scores between groups. The significance level was 5%. Results  The final sample consisted of 17 patients (case group) and 27 (control group). The Shapiro-Wilk test revealed normal distribution ( p  > 0.05). A HADS score > 0.70 (Cronbach alpha) was reliable and presented good internal consistency. Patients with adhesive capsulitis reported "doubtful" (average/standard deviation = 8.88/4.50) "anxious symptoms" ( p  = 0.019) but no "depressive symptoms" (average/standard deviation = 6.41/3.69), despite p  = 0.015. Conclusion  There is a "doubtful" positive association between anxiety symptoms and adhesive capsulitis but a negative association with depressive symptoms.

Sleep Disturbance in Musculoskeletal Conditions: Impact of a Digital Care Program

Background

Musculoskeletal (MSK) pain is highly prevalent worldwide, resulting in significant disability, and comorbid sleep disturbances. Digital therapy for MSK pain can provide significant improvements in care access, alongside pain and disability reductions. However, studies on the effect of such programs on sleep are lacking.

Purpose

To evaluate the impact on pain-related sleep impairment after a 12-week remote multimodal digital care program (DCP) for MSK conditions.

Patients and Methods

This is an ad-hoc analysis of a decentralized single-arm study into engagement and clinical outcomes after a DCP for MSK rehabilitation. Patients were stratified by baseline sleep disturbance, based on sleep questions in the questionnaires: Oswestry Disability Index, Neck Disability Index, and the Quick Disabilities of the Arm, Shoulder and Hand questionnaire. Additional outcomes were pain, Generalized Anxiety Disorder 7-item scale, Patient Health 9-item questionnaire, Work Productivity, and Activity Impairment, and program engagement.

Results

At baseline, 5749 patients reported sleep disturbance (78.0% of eligible patients). These reported significantly worse clinical outcomes at baseline than patients without sleep disturbance (all p<0.001). Patients with comorbid sleep disturbance showed improvements in sleep, with a significant proportion reporting full recovery at program completion: 56% of patients with upper limb conditions (including 10% of patients with severe sleep disturbance at baseline), and 24% with spine conditions. These patients also reported significant improvements in all clinical outcomes at program completion. Engagement and satisfaction were high, and also higher than in patients without sleep impairment.

Conclusion

This is the first study of its kind investigating the effect of a completely remote DCP for MSK pain on sleep. Patients reporting comorbid sleep disturbance had significant improvement in sleep, alongside pain, mental health and work productivity at program completion. The results suggest that a DCP for MSK pain can improve sleep disturbances in patients with upper limb and spine conditions.

Biopsychosocial Approach in Identifying Risk Factors of Kinesiophobia in Persons with Subacromial Pain Syndrome and Developing a Clinical Prediction Tool

Introduction

Although the negative effects of kinesiophobia on functional status in subacromial pain syndrome (SAPS) patients are clearly demonstrated, no study examines the risk factors of kinesiophobia in individuals with SAPS from a biopsychosocial perspective. The present study aims to determine the risk factors of kinesiophobia in individuals with SAPS using a biopsychosocial approach. This study also aims to explore the compounding effects of multiple associative risk factors by developing a clinical prediction tool to identify SAPS patients at higher risk for kinesiophobia.

This cross-sectional study included 549 patients who were diagnosed with SAPS. The Tampa-Scale of Kinesiophobia (TSK) was used to assess kinesiophobia. Visual analog scale (VAS), The Shoulder Pain and Disability Index (SPADI), Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, the presence of metabolic syndrome, using any non-steroidal anti-inflammatory drugs, Pain Catastrophizing Scale (PCS), Illness Perception Questionnaire-revised (IPQ-R), Hospital Anxiety and Depression Scale (HADS), behavioral pattern of the patient, sociodemographic characteristics, and treatment expectancy were outcome measures.

Results

Thirteen significant risk factors of having kinesiophobia were: VASat rest (≥ 5.2), VASduring activity (≥ 7.1), DASH (≥ 72.1), presence of metabolic syndrome, PCShelplessness (≥ 16.1), IPQ-Rpersonal control (≤ 17.1), IPQ-Rtreatment control (≤ 16.3), HADSdepression (≥ 7.9), avoidance behavior type, being female, educational level (≤ high school), average hours of sleep (≤ 6.8), and treatment expectancy (≤ 6.6). The presence of seven or more risk factors increased the probability of having high level of kinesiophobia from 34.3 to 51%.

Conclusions

It seems necessary to address these factors, increase awareness of health practitioners and individuals.

Arthroscopic Repair Benefits Reparable Rotator Cuff Tear Patients Aged 65 Years or Older With a History of Traumatic Events

PURPOSE

To evaluate the clinical outcomes of arthroscopic rotator cuff repair at 2-year follow-up in patients aged 65 years or older with a history of traumatic events divided into groups based on symptom duration (<3 months, 3-6 months, and >6 months from injury to surgery) and to compared patient-reported outcomes among the 3 groups.

METHODS

Between 2015 and 2020, 110 patients who met the inclusion criteria were enrolled in this study; these patients were divided into 3 groups according to symptom duration: less than 3 months (group A), 3 to 6 months (group B) and more than 6 months (group C). Preoperative and 2-year postoperative clinical outcomes were compared, including American Shoulder and Elbow Surgeons, Constant-Murley, University of California, Los Angeles, Simple Shoulder Test, and visual analog scale scores; forward elevation; external rotation; and internal rotation. The minimal clinically important difference (MCID), patient acceptable symptom state, substantial clinical benefit, and maximum outcome improvement were also compared among the groups.

RESULTS

The American Shoulder and Elbow Surgeons score, as the primary outcome, improved significantly from 41.0 ± 18.5 to 85.4 ± 8.1 in group A, from 53.7 ± 14.3 to 86.3 ± 11.7 in group B, and from 49.7 ± 18.5 to 83.9 ± 11.9 in group C. All the other parameters showed statistically significant improvements at 2-year follow-up in each group (all P < .05). There was no significant difference in each parameter among the 3 groups except the visual analog scale score, which did not achieve the MCID. Overall, 86 patients (78.2%) exceeded the MCID, 87 patients (79.1%) achieved the patient acceptable symptom state, 77 patients (70.0%) achieved substantial clinical benefit, and 62 patients (56.4%) achieved maximum outcome improvement without significant differences among the 3 groups.

CONCLUSIONS

In rotator cuff tear patients aged 65 years or older with a history of traumatic events, arthroscopic rotator cuff repair significantly improves clinical outcomes at 2-year follow-up regardless of symptom duration if the tear is fully reparable.

Transarterial Embolization of Neovascularity for Refractory Nighttime Shoulder Pain: A Multicenter, Open-Label, Feasibility Trial

PURPOSE

To assess the feasibility of transarterial embolization (TAE) for recalcitrant nighttime shoulder pain in a multicentric study.

MATERIALS AND METHODS

This prospective, open-label, feasibility trial included 100 patients treated at 5 institutions. TAE was performed in 76 patients with adhesive capsulitis (AC) and 24 patients with symptomatic rotator cuff tears (sRCTs). The ipsilateral radial artery was punctured, and imipenem/cilastatin sodium was infused as an embolic agent. Adverse events, 10 point pain numerical rating scale (NRS), range of motion (ROM) of the shoulder joint, and quality of life (via the EuroQol-5D [EQ-5D]) were evaluated.

RESULTS

All patients exhibited neovascularity on baseline angiography, and all TAE procedures were performed successfully. No patient experienced a major adverse event. The mean nighttime pain NRS scores at baseline and 1, 3, and 6 months after TAE were 6.4 ± 2.2, 3.4 ± 2.6, 2.3 ± 2.5, and 1.6 ± 2.2, respectively (for all, P < .001). The mean ROM of anterior elevation at baseline and 1, 3, and 6 months after TAE were 97° ± 29°, 119° ± 28°, 135° ± 27°, and 151° ± 17°, respectively (for all, P < .001). The mean EQ-5D scores at baseline and 1, 3, and 6 months after TAE were 0.63 ± 0.17, 0.73 ± 0.16, 0.80 ± 0.17, and 0.84 ± 0.17, respectively (for all, P < .001). There was no significant difference in the clinical success rate between the AC and sRCT groups.

CONCLUSIONS

TAE for nighttime shoulder pain caused by AC and sRCTs was feasible with sufficient safety and efficacy.

Association between adhesive capsulitis and depression: A five-year retrospective cohort study including 58,516 adults from Germany

BACKGROUND

Little is known on the longitudinal relationship between adhesive capsulitis and depression. Therefore, the aim of this study was to investigate the association between adhesive capsulitis and the five-year cumulative incidence of depression in adults from Germany.

METHODS

The present retrospective cohort study included all adults aged ≥18 years with a first diagnosis of adhesive capsulitis in one of 1198 general practices in Germany between January 2010 and December 2018 (index date). Patients with adhesive capsulitis were matched to those without adhesive capsulitis using a propensity score based on age, sex, index year, average number of visits per year, and diagnoses documented prior to or at the index date (i.e., thyroid gland disorders, diabetes mellitus, coronary heart disease, cerebrovascular diseases, and Parkinson's disease and secondary parkinsonism). In individuals without adhesive capsulitis, the index date was a randomly selected visit date.

RESULTS

This study included 29,258 patients with and 29,258 patients without adhesive capsulitis (mean [SD] age 55.9 [15.6] years; 53.2% men). Within five years of the index date, there were 17.5% of patients with adhesive capsulitis and 8.7% of those without adhesive capsulitis diagnosed with incident depression (log-rank p-value<0.001). This result was corroborated in the Cox regression analysis, as there was a positive and significant association between adhesive capsulitis and the cumulative incidence of depression (HR = 1.86, 95% CI: 1.78-1.95).

CONCLUSION

In this study, adhesive capsulitis was associated with an increased cumulative incidence of depression. Further research is warranted to better understand the mediating factors involved in this relationship.

What factors contribute to the Scapular Assistance Test result? A classification and regression tree approach

The aim of this study was to determine predictive factors related to the Scapular Assistance Test in individuals with shoulder pain during arm elevation, and to analyze how these predictors interact in a nonlinear manner to discriminate the result of a positive and negative Scapular Assistance Test. Eighty-four individuals with shoulder pain with positive (n = 47, average age 38.4 years) and negative (n = 37, average age 37.8 years) Scapular Assistance Test completed the study. Demographic data, affected shoulder, pain duration, pain at rest, angular onset of pain, scapular dyskinesis, serratus anterior and lower trapezius muscle strength, Disabilities of Arm, Shoulder and Hand questionnaire and Pain Catastrophizing Scale were assessed in all participants. The Classification and Regression Tree analysis was used to determine which factors would predict the occurrence of a positive or negative Scapular Assistance Test and possible interactions among them. The resulting tree presented seven levels that combine the following variables: angular onset of pain, presence of scapular dyskinesis, pain catastrophizing, serratus anterior and lower trapezius muscle strength. The angular onset of pain during arm elevation was the main predictor of a positive Scapular Assistance Test selected by the Classification and Regression Tree. This study indicates that the Scapular Assistance Test result may be explained not only by biomechanical variables, but also by psychological factors. Disability of the upper limbs does not seem to contribute to the Scapular Assistance Test result.

The Unhappy Shoulder: A Conceptual Review of the Psychosomatics of Shoulder Pain

INTRODUCTION

Chronic pain is a multifaceted disorder genuinely entangled with psychic and psychosomatic symptoms, which are typically involved in the processes of chronification. The impingement syndrome of the shoulder is no exception to this rule, but several studies have shown respective peculiarities among those with pain and impingement of the shoulder. Notably, chronic pain is a lateralized experience, and, similarly, its psychosomatic correlates may be attached to the hemispheres functionally.

AIM

The present review therefore gives an overview of the respective findings, with regard not only to psychopathology, but also to personality factors and psychologic trauma, since the latter are reportedly associated with chronic pain. Moreover, we acknowledge symmetry as a possible pathogenic factor.

METHODS

This narrative review followed the current standards for conducting narrative studies. Based on prior findings, our research strategy included the relevance of psychotraumatologic and symmetrical aspects, as well as comorbidity. We retrieved the relevant literature reporting on the impact of psychopathology as well as personality features on shoulder pain, as published up to January 2022 from the Medline database (1966-2022). Study selecton: We included numerous studies, and considered the contextual relevance of studies referring to the neuropsychosomatics of chronic pain.

RESULTS

Pain-specific fears, depression, and anxiety are important predictors of shoulder pain, and the latter is generally overrepresented in those with trauma and PTSD. Moreover, associations of shoulder pain with psychological variables are stronger as regards surgical therapies as compared to conservative ones. This may point to a specific and possibly trauma-related vulnerability for perioperative maladaptation. Additionally, functional hemispheric lateralization may explain some of those results given that limb pain is a naturally lateralized experience. Not least, psychosocial risk factors are shared between shoulder pain and its physical comorbidities (e.g., hypertension), and the incapacitated state of the shoulder is a massive threat to the function of the human body as a whole.

CONCLUSIONS

This review suggests the involvement of psychosomatic and psychotraumatologic factors in shoulder impingement-related chronic pain, but the inconclusiveness and heterogeneity of the literature in the field is possibly suggestive of other determinants such as laterality.

Are psychosocial variables, sleep characteristics or central pain processing prognostic factors for outcome following rotator cuff repair? A protocol for a prospective longitudinal cohort study

INTRODUCTION

Prognosis following surgical rotator cuff repair (RCR) is often established through the assessment of non-modifiable biomedical factors such as tear size. This understates the complex nature of recovery following RCR. There is a need to identify modifiable psychosocial and sleep-related variables, and to find out whether changes in central pain processing influence prognosis after RCR. This will improve our knowledge on how to optimise recovery, using a holistic rehabilitation approach.

METHODS AND ANALYSIS

This longitudinal study will analyse 141 participants undergoing usual care for first time RCR. Data will be collected 1-21 days preoperatively (T1), then 11-14 weeks (T2) and 12-14 months (T3) postoperatively. We will use mixed-effects linear regression to assess relationships between potential prognostic factors and our primary and secondary outcome measures-the Western Ontario Rotator Cuff Index; the Constant-Murley Score; the Subjective Shoulder Value; Maximal Pain (Numeric Rating Scale); and Quality of Life (European Quality of Life, 5 dimensions, 5 levels). Potential prognostic factors include: four psychosocial variables; pain catastrophising, perceived stress, injury perceptions and patients' expectations for RCR; sleep; and four factors related to central pain processing (central sensitisation inventory, temporal summation, cold hyperalgesia and pressure pain threshold). Intercorrelations will be assessed to determine the strength of relationships between all potential prognostic indicators.Our aim is to explore whether modifiable psychosocial factors, sleep-related variables and altered central pain processing are associated with outcomes pre-RCR and post-RCR and to identify them as potential prognostic factors.

ETHICS AND DISSEMINATION

The results of the study will be disseminated at conferences such as the European Pain Congress. One or more manuscripts will be published in a peer-reviewed SCI-ranked journal. Findings will be reported in accordance with the STROBE statement and PROGRESS framework. Ethical approval is granted by the Ethical commission of Canton of Zurich, Switzerland, No: ID_2018-02089 TRIAL REGISTRATION NUMBER: NCT04946149.

Sex Differences in Comorbidity Combinations in the Swedish Population

High comorbidity rates, especially mental–physical comorbidity, constitute an increasing health care burden, with women and men being differentially affected. To gain an overview of comorbidity rates stratified by sex across a range of different conditions, this study examines comorbidity patterns within and between cardiovascular, pulmonary, skin, endocrine, digestive, urogenital, musculoskeletal, neurological diseases, and psychiatric conditions. Self-report data from the LifeGene cohort of 31,825 participants from the general Swedish population (62.5% female, 18–84 years) were analyzed. Pairwise comorbidity rates of 54 self-reported conditions in women and men and adjusted odds ratios (ORs) for their comparison were calculated. Overall, the rate of pairwise disease combinations with significant comorbidity was higher in women than men (14.36% vs. 9.40%). Among psychiatric conditions, this rate was considerably high, with 41.76% in women and 39.01% in men. The highest percentages of elevated mental–physical comorbidity in women were found for musculoskeletal diseases (21.43%), digestive diseases (20.71%), and skin diseases (13.39%); in men, for musculoskeletal diseases (14.29%), neurological diseases (11.22%), and digestive diseases (10%). Implications include the need for integrating mental and physical health care services and a shift from a disease-centered to an individualized, patient-centered focus in clinical care.

The correlation between shoulder pathologies and sleep disorders

OBJECTIVE

To assess and characterize the correlation between shoulder pathologies and sleep disturbances.

METHODS

Participants enrolled into this case-control study were divided into two groups: patients with an established clinical diagnosis of active shoulder pathology (study group), and patients without any shoulder pathology (control group). All patients completed the Insomnia Severity Index (ISI) questionnaire, in addition to questions related to participant demographics, health status, medication, and other known insomnia risk factors.

RESULTS

A total of 98 patients were included (46 in the study group and 52 controls). Mean ISI score was significantly higher (indicating more severe insomnia) in the study group versus control group (t[96] = -9.67), even after correcting for confounders (t[53.1] = -8.61). Additionally, in patients with shoulder pathology, those with comorbidities experienced more sleep disturbances than those without comorbidities (β = 0.36). Lastly, the shoulder pathology group was at a higher risk of having sleep disturbances compared with controls (relative risk 4.86, 95% confidence interval 2.24, 10.55).

CONCLUSIONS

Sleep disturbances are more common among patients with shoulder pathologies. Comorbidities and a shorter duration of pathology may predict more severe sleep disturbances.

Depression and Anxiety Are Associated With Worse Subjective and Functional Baseline Scores in Patients With Frozen Shoulder Contracture Syndrome: A Systematic Review

Purpose

To investigate whether psychological factors, such as avoidance behavior, fear, pain catastrophization, kinesiophobia, anxiety, depression, optimism, and expectation are associated with different subjective and functional baseline scores in patients with frozen shoulder contracture syndrome (FSCS).

Methods

Searches were conducted in MEDLINE, Cochrane Library (CENTRAL Database), PEDro, Pubpsych, and PsychNET.APA without restrictions applied to language, date, or status of publication. Two authors reviewed study titles, abstract, and full text based on the following inclusion criteria: adult population (≥ 30 < 70 years old) with FSCS.

Results

Seven hundred and seventy-six records were included by the search strategies. After title final screening, 6 studies were included for the qualitative synthesis. Psychological features investigated were anxiety, depression, pain-related fear, pain catastrophizing, and pain self-efficacy; reported outcomes included pain, function, disability, quality of life, and range of motion. Data suggest that anxiety and depression impact self-assessed function, pain, and quality of life. There is no consensus on the correlation between psychological variables and range of motion. Associations were suggested between pain-related fear, pain-related beliefs, and pain-related behavior and perceived arm function; pain-related conditions showed no significant correlation with range of motion and with perceived stiffness at baseline.

Conclusion

Scores traditionally thought to assess physical dimensions like shoulder pain, disability, and function seem to be influenced by psychological variables. In FSCS patients, depression and anxiety were associated with increased pain perception and decreased function and quality of life at baseline. Moreover, pain-related fear and catastrophizing seem to be associated with perceived arm function.

Nocturnal pain in patients with rotator cuff related shoulder pain: A prospective study

INTRODUCTION

Nocturnal pain is a common complaint in rotator cuff related shoulder pain (RCRSP), and there is no study in literature that has evaluated the relationship between nocturnal pain severity and other evaluation parameters in RCRSP. The objective of the study was to investigate the relationship between the severity of nighttime pain and demographic and clinical data including physical examination findings, magnetic resonance imaging (MRI) findings, disability, kinesiophobia, and quality of life scores in patients diagnosed with RCRSP.

MATERIALS AND METHODS

We assessed 61 patients (52.4% female) using the Visual Analog Scale (VAS) for nighttime and daytime, Shoulder Pain and Disability Questionnaire (SPADI), Tampa Scale of Kinesiophobia (TSK), and Short Form-36 (SF-36). Demographic and clinical data were recorded and rotator cuff specific examinations were performed and documented. RCRSP lesions were evaluated in terms of tendonitis and rupture by MRI.

RESULTS

The nighttime VAS score was positively correlated with SPADI disability and total scores, and daytime VAS score, and negatively correlated with SF-36 physical function subscale. The nighttime VAS score was associated with presence of calcific tendonitis in supraspinatus, infraspinatus tendinosis, and subscapularis tendinosis. On multivariate analysis with a linear regression model, presence of subscapularis tendinosis was an independent predictor of nighttime VAS score. In shoulder clinical tests, the nighttime VAS score correlated with only Neer test positivity.

CONCLUSIONS

Our results suggest that there is a relationship between nocturnal pain severity and disability. Presence of subscapularis tendinosis appears to be a predictor of nocturnal pain severity. Additionally, patients with positive Neer test may experience more nocturnal pain.

Conclusions

Does your sleeping position affect your shoulder pain?

Aim: This study aimed to evaluate patients with shoulder pain according to their sleeping positions based on their clinical and magnetic resonance imaging (MRI) findings and to determine possible factors affecting shoulder pain. Material and Method: A total of 115 patients were included in the study. The severity of shoulder pain was evaluated with the visual analog scale (VAS), shoulder function was evaluated with the simple shoulder test, and the ability to perform physical activities was evaluated with the QuickDASH questionnaire. The biceps tendon, rotator cuff (RC), subacromial-subdeltoid bursa, glenohumeral joint (GHJ), and acromioclavicular joint (ACJ) were evaluated using MRI. Results: Of the patients with shoulder pain, 66.1% were female, 50.4% were primary school graduates, 53.9% were housewives, and 41.7% had a systemic disease. The mean age of the patients was 50.48±13.61 years while the median BMI and VAS values were 26.1 (18.2-41.4) and 8 (2-10), respectively. Considering the sleeping positions, it was found that 39.1% (most common) of the patients were sleeping in the fetus position, and considering the results of patients’ MRI examinations, the most common problem was related to the pathologies of the supraspinatus tendon (42.6%). It was found that sleep quality, which was poor in all patients, was worse in females (p=0.311), in those over 50 years of age (p=0.007), and those with a systemic disease (0.325). It was discovered that Pittsburgh's sleep quality index score was generally worse in those who slept in the soldier position and in the log position (p>0.05). The rates of pathologies of the supraspinatus tendon were found to be the highest in those that slept in the fetus position (p=0.931). It was also found that the rates of impingement, bicipital tendinitis, combined problems, and adhesive capsulitis did not differ significantly according to sleeping positions. Although occupational variables for supraspinatus degeneration remained significant in the model, having a desk job statistically significantly increased the probability of supraspinatus degeneration by 3.38 times when compared to being a housewife (95% CI=1.143-9.996; p=0.028) and it was identified that the probability of acromioclavicular degeneration increased by 1.16 times for every 1-unit increase in BMI. Conclusion: Different sleeping positions may predispose to different shoulder pathologies and shoulder pain, and shoulder pathologies may lead to deterioration of sleep quality, especially in older patients. For this reason, suggesting correct and appropriate sleeping positions may be a useful treatment method in reducing pain and disability and increasing sleep quality.

Shoulder Surgery as an Effective Treatment for Shoulder-Related Sleep Disturbance: A Systematic Review

PURPOSE

The purpose of this systematic review is to evaluate the current literature in an effort to investigate sleep quality and disturbances and the association with clinical outcomes of patients undergoing shoulder surgery.

METHODS

A systematic review of the PubMed, Embase, and Cochrane Library databases was performed according to PRISMA guidelines. All English-language literature reporting clinical outcomes and sleep quality and disturbance after shoulder surgery was reviewed by 2 independent reviewers. Outcomes assessed included patient-reported outcomes (PROs) and sleep quality. Specific PROs included the Pittsburgh Sleep Quality Index (PSQI), Visual Analog Scale (VAS) for pain, Simple Shoulder Test (SST), University of California Los Angeles (UCLA) Shoulder Rating Scale, and American Shoulder and Elbow Surgeons Score (ASES). Study methodology was assessed using the Modified Coleman Methodology Score. Descriptive statistics are presented.

RESULTS

Sixteen studies (11 level IV, 2 level III, 3 level II) with a total of 2748 shoulders were included (age, 12-91 years; follow-up, 0.25-132 months). In total, 2198 shoulders underwent arthroscopic rotator cuff repair (RCR), 131 shoulders underwent arthroscopic capsular release, 372 shoulders underwent total shoulder arthroplasty (TSA), 18 shoulders underwent comprehensive arthroscopic management, and 29 shoulders underwent sternoclavicular joint procedures. All shoulder surgeries improved self-reported sleep and PROs from before to after surgery. In RCR patients, PSQI scores were significantly associated with VAS scores, SST scores (r = 0.453, r = -0.490, P < .05, respectively), but not significantly associated with UCLA Shoulder rating scale or the ASES scores (r = 0.04, r = 0.001, P > .05, respectively). In TSA patients, PSQI scores were significantly associated with ASES scores (r = -0.08, P < .05). All 4 RCR studies and 1 TSA study using PSQI found significant improvements in mean PSQI scores within 6 to 24 months (P < .05).

CONCLUSIONS

Surgical intervention for rotator cuff tear and glenohumeral osteoarthritis significantly improves self-reported sleep in patients with shoulder pain. However, there remains a dearth of available studies assessing the effects of surgical intervention for adhesive capsulitis, sternoclavicular joint instability, and sternoclavicular osteoarthritis on sleep. Future studies should use sleep-specific PROs and quantitative measures of sleep to further elucidate the relationship between sleep and the effect of shoulder surgery.

International physical therapists consensus on clinical descriptors for diagnosing rotator cuff related shoulder pain: A Delphi study

BACKGROUND

There is a lack of standardized criteria for diagnosing rotator cuff related shoulder pain (RCRSP).

OBJECTIVE

To identify the most relevant clinical descriptors for diagnosing RCRSP.

METHODS

A Delphi study was conducted through use of an international physical therapists expert panel. A 3-round Delphi survey involving an international panel of physical therapists experts with extensive clinical, teaching, and research experience was conducted. A search query was performed in Web of Science, along with a manual search, to find the experts. The first round was composed of items obtained from a previous pilot Delphi study along with new items proposed by the experts. Participants were asked to rate items across six clinical domains using a five-point Likert scale. An Aiken's Validity Index ≥ 0.7 was considered indicative of group consensus.

RESULTS

Fifteen experts participated in the Delphi survey. After the three rounds, consensus was reached on 18 clinical descriptors: 10 items were included in the "subjective examination" domain, 1 item was included in the "patient-reported outcome measures" domain, 3 items in the "diagnostic examination" domain, 2 items in the "physical examination" domain", and 2 items in the "functional tests" domain. No items reached consensus within the "special tests" domain. The reproduction of symptoms in relation to the application of load, the performance of overhead activities, and the need of active and resisted movement assessment were some of the results with greatest consensus.

CONCLUSION

In this Delphi study, a total of 18 clinical descriptors across six clinical domains were agreed upon for diagnosing RCRSP.

Treatment of partial rotator cuff lesions is associated with a higher frequency of post-operative shoulder stiffness. A prospective investigation on the role of surgery-related risk factors for this complication

PURPOSE

Post-operative shoulder stiffness (SS) is a common complication after arthroscopic rotator cuff (RC) repair. The aim of this prospective study is to evaluate the role of surgical risk factors in the development of this complication, with special focus on the characteristics of the RC tears.

METHODS

Two-hundred and twenty patients who underwent arthroscopic RC repair for degenerative posterosuperior RC tears were included. Surgery-related risk factors for development of post-operative SS belonging to the following five categories were documented and analyzed: previous surgery, RC tear characteristics, hardware and repair type, concomitant procedures, time and duration of surgery. The incidence of post-operative SS was evaluated according to the criteria described by Brislin and colleagues.

RESULTS

The incidence of post-operative SS was 8.64%. The treatment of partial lesions by tear completion and repair technique was significantly associated with development of post-operative SS (p = 0.0083, pc = 0.04). A multivariate analysis revealed that treatment of partial lesions in patients younger than 60 years was associated to a higher risk of developing post-operative SS (p = 0.007). Previously known pre-operative risk factors such as female sex and younger age were confirmed. No other significant associations were documented.

CONCLUSION

The treatment of partial lesions of the RC may lead to a higher risk of post-operative SS than the treatment of complete lesions, in particular in patients younger than 60 years. Possible explanations of this finding are the increased release of pro-inflammatory cytokines caused by the additional surgical trauma needed to complete the lesion and the different pain perception of the subgroup of patients who require surgical treatment already for partial tears.

EVIDENCE

A higher risk of post-operative SS should be expected after tear completion and repair of partial lesions, especially in young patients. Appropriate pre-operative counseling and post-operative rehabilitation should be considered when approaching this subgroup of RC tears.

Effects of obesity on clinical and functional outcomes following anatomic and reverse total shoulder arthroplasty

BACKGROUND

Limited data exist regarding the clinical and functional outcomes following primary total shoulder arthroplasty in obese patients. The purpose of this study is to determine the effects of obesity on the clinical and functional outcomes following primary anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) in a large patient population with mid-term follow-up.

METHODS

Patients in a multi-institutional shoulder registry receiving either primary aTSA (n = 1520) or rTSA (n = 2054) from 2004 to 2018 with a minimum follow-up period of 2 years were studied. All patients received the same single-platform shoulder prosthesis. Study groups were assigned based on implant type (anatomic or reverse), and further stratification was based on patient body mass index (BMI), with obese patients having a BMI ≥ 30 and non-obese patients having a BMI < 30. Patients were evaluated and scored preoperatively and at latest follow-up by use of 5 scoring metrics and range of motion (ROM).

RESULTS

The mean follow-up period was 5 years (range, 2-14 years). Obese patients comprised 41% of the aTSA group and 35% of the rTSA group. Significant postoperative improvements in visual analog scale pain scores, ROM, and all 5 scoring metrics occurred in both obese and non-obese patients (P < .05). Obese patients in both groups reported higher preoperative and postoperative visual analog scale pain scores and less preoperative and postoperative ROM compared with non-obese patients. Compared with non-obese patients, obese patients receiving aTSA reported significantly worse postoperative Simple Shoulder Test, Constant-Murley, American Shoulder and Elbow Surgeons, University of California, Los Angeles, and Shoulder Pain and Disability Index scores compared with non-obese patients, and those receiving rTSA reported significantly worse American Shoulder and Elbow Surgeons and Shoulder Pain and Disability Index scores (all P < .05). However, these differences did not exceed the minimal clinically important difference or substantial clinical benefit criteria. Radiographic analysis showed that in the rTSA group, obese patients had significantly less postoperative scapular notching and a lower scapular notching grade compared with non-obese patients (P < .05).

DISCUSSION

Both non-obese and obese patients can expect clinically significant improvements in pain, motion, and functional outcome scores following both aTSA and rTSA. Obese patients reported significantly more postoperative pain, lower outcome scores, and less ROM compared with non-obese patients after both aTSA and rTSA at a mean follow-up of 5 years. However, statistically significant differences were not found to be clinically significant with respect to established minimal clinically important difference and substantial clinical benefit criteria. Therefore, obese and non-obese patients experience similar clinical outcomes following total shoulder arthroplasty, regardless of BMI. However, obese patients have more comorbidities, greater intraoperative blood loss, and less scapular notching compared with non-obese patients.

Serum Levels of TNF-α Are Increased in Patients with Rotator Cuff Tear and Sleep Disturbance

The purpose of this study was to determine serum levels of sleep-related cytokines in patients with rotator cuff tear (RCT) who were experiencing pain-related sleep disturbance. Peripheral blood samples before surgery were collected from 63 study participants and divided into three groups: RCT with sleep disturbance group; SD group (n = 21), RCT with normal sleep group; NS group (n = 21), and patients with chronic shoulder instability; control group (n = 21). Serum concentration levels of interleukin-1α (IL-1α), IL-1β, IL-2, IL-6, IL-8, IL-10, and tumor necrosis factor-α (TNF-α) were measured via ELISA. The associations between serum levels of sleep-related cytokines and clinical scores and the Pittsburgh Sleep Quality Index (PSQI) were analyzed. Serum concentration levels of TNF-α were significantly higher in the SD group compared with those of the NS and control groups (p = < 0.001 and 0.05). Serum levels of IL-8 and IL-10 were significantly higher in the SD group compared with those of control group (p = 0.01 and = 0.05), but did not differ significantly from that of the NS group. There were no associations between serum levels of sleep-related cytokines and all clinical scores. The current findings suggest that TNF-α may be associated with sleep disturbance in patients with RCT.

Effects of ischemic compression and instrument-assisted soft tissue mobilization techniques in trigger point therapy in patients with rotator cuff pathology: randomized controlled study

PURPOSE

To compare the ischaemic compression (IC) and instrument-assisted soft tissue mobilization (IASTM) in the treatment of MTrPs in addition to standard rehabilitation program in patients with rotator cuff tears.

METHODS

Participants with rotator cuff tears were included the study (n = 46). Patients were randomly divided into two groups; which were Group 1 (IC + standard rehabilitation program (n = 23)), and Group 2 (IASTM + standard rehabilitation program (n = 23)) groups. Pain were assessed by visual analog scale (VAS). Range of motion (ROM) was assessed by a universal goniometer. Active MTrPs were assessed according to the Travel and Simons criteria. Pressure pain threshold (PPT) were assessed by a digital algometer. Function were evaluated by the Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH) and American Shoulder and Elbow Surgeons Standardised Shoulder Assessment (ASES) Form. Anxiety and depression were evaluated by the Hospital Anxiety and Depression (HAD) scale. Satisfaction was assessed by the Global Rating of Change scale after 6 weeks treatment.

RESULTS

After the treatment, pain, ROM and the DASH, ASES, HAD scores improved in both groups (p < 0.05). The active MTrPs of 2 muscles, PPT of 4 muscles and DASH in Group 1 significantly improved compared to Group 2 (p < 0.05).

CONCLUSION

Although patients with low functionality accumulated in the IC group, the IC is more effective than the IASTM in increasing the PPT and functional improvement according to the results of the DASH score.

Simultaneous or Staged Bilateral Arthroscopic Rotator Cuff Repair: An Observational Study of Intraoperative and Postoperative Outcomes

Background:

Bilateral arthroscopic rotator cuff repair (ARCR) is frequently performed in patients with symptomatic bilateral rotator cuff tears.

Purpose:

To compare patient-reported outcomes and mobility between simultaneous and staged bilateral ARCR.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Included were 51 patients who underwent simultaneous (anesthetized once) and 42 patients who underwent staged (anesthetized twice) bilateral ARCR between January 2014 and January 2018; for the staged group, the interval between procedures was at least 12 months. All operations were performed by the same surgeon, and all patients had minimum 24-month follow up in both shoulders. Patient-reported outcomes and range of motion (ROM) were assessed preoperatively and postoperatively and compared between groups. Outcome measures included the Constant-Murley score (CMS) and American Shoulder and Elbow Surgeons (ASES) score as well as measures of psychological status, health-related quality of life, activities of daily living (ADL), and patient satisfaction with the state of one’s shoulders.

Results:

The mean follow-up times for the staged and simultaneous ARCR groups were 44.1 months (range, 36-60 months) and 37.5 months (range, 25-59 months), respectively. There were no significant differences in age, tear size, or fatty degeneration of rotator cuff muscles between the groups. The cumulative length of hospital stay in the staged group was significantly longer than in the simultaneous group (P < .001). At the final follow-up, both groups showed significant improvement in ROM, CMS, and ASES scores (P < .05). No significant differences between the groups were observed in terms of ROM, CMS, and ASES scores postoperatively. At 24 months postoperatively, psychological status and health-related quality of life in both groups improved significantly (P < .05), and there were no significant between-group differences. Patients were able to perform most essential ADL. Both groups had high patient satisfaction, but patient satisfaction for the second shoulder of the staged group was lower than that of the simultaneous group (P = .039).

Conclusion:

Simultaneous bilateral ARCR was shown to be effective, resulting in similar improvements in clinical outcomes to staged bilateral ARCR at 2-year follow-up. In addition to higher patient satisfaction, simultaneous bilateral ARCR also had a shorter treatment cycle.

Prior mood disorder diagnoses do not relate to current mood disorder symptoms or patient-reported disease severity in rotator cuff patients

BACKGROUND

Surgery for rotator cuff syndrome does not always produce symptom improvement. Biological factors may explain some symptoms, but mood disorder symptoms may also contribute. The purpose of this study is to examine the interaction between disease severity, prevalence of mood disorder diagnoses, and current mood disorder symptoms in preoperative rotator cuff patients.

METHODS

A prospective cohort of patients aged 35-75 years with unilateral rotator cuff disease awaiting surgery participated. Demographics, psychiatric history, the Hospital Anxiety & Depression Scale, and the Western Ontario Rotator Cuff index were collected. Descriptive and univariate statistical testing was performed.

RESULTS

Of 140 participants (75M:65W) aged 55 ± 8 years, 34 reported a prior diagnosis of a mood disorder. There was a moderate positive relationship between disease severity and current depression and anxiety scores. Women were more likely to carry a diagnosis of a mood disorder, but there were no differences in current symptom levels between genders. No differences were found in patient-reported outcome measure scores between patients with and without a mood disorder diagnosis.

DISCUSSION

Current mood disorder symptoms were associated with greater disease severity, whereas the presence of a past mood disorder diagnosis was not. Awareness of this relationship may reduce bias about past mood disorder diagnoses during decision-making.

Kinesio taping for rotator cuff disease

BACKGROUND

Kinesio Taping (KT) is one of the conservative treatments proposed for rotator cuff disease. KT is an elastic, adhesive, latex-free taping made from cotton, without active pharmacological agents. Clinicians have adopted it in the rehabilitation treatment of painful conditions, however, there is no firm evidence on its benefits.

OBJECTIVES

To determine the benefits and harms of KT in adults with rotator cuff disease.

SEARCH METHODS

We searched the Cochrane Library, MEDLINE, Embase, PEDro, CINAHL, Clinicaltrials.gov and WHO ICRTP registry to July 27 2020, unrestricted by date and language.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials (RCTs) including adults with rotator cuff disease. Major outcomes were overall pain, function, pain on motion, active range of motion, global assessment of treatment success, quality of life, and adverse events.

DATA COLLECTION AND ANALYSIS

We used standard methodologic procedures expected by Cochrane.

MAIN RESULTS

We included 23 trials with 1054 participants. Nine studies (312 participants) assessed the effectiveness of KT versus sham therapy and fourteen studies (742 participants) assessed the effectiveness of KT versus conservative treatment. Most participants were aged between 18 and 50 years. Females comprised 52% of the sample. For the meta-analysis, we considered the last available measurement within 30 days from the end of the intervention. All trials were at risk of performance, selection, reporting, attrition, and other biases.  Comparison with sham taping Due to very low-certainty evidence, we are uncertain whether KT improves overall pain, function, pain on motion and active range of motion compared with sham taping. Mean overall pain (0 to 10 scale, 0 no pain) was 2.96 points with sham taping and 3.03 points with KT (3 RCTs,106 participants), with an absolute difference of 0.7% worse, (95% CI 7.7% better to 9% worse) and a relative difference of 2% worse (95% CI 21% better to 24% worse) at four weeks. Mean function (0 to 100 scale, 0 better function) was 47.1 points with sham taping and 39.05 points with KT (6 RCTs, 214 participants), with an absolute improvement of 8% (95% CI 21% better to 5% worse)and a relative improvement of 15% (95% CI 40% better to 9% worse) at four weeks. Mean pain on motion (0 to 10 scale, 0 no pain) was 4.39 points with sham taping and 2.91 points with KT even though not clinically important (4 RCTs, 153 participants), with an absolute improvement of 14.8% (95% CI 22.5% better to 7.1% better) and a relative improvement of 30% (95% CI 45% better to 14% better) at four weeks. Mean active range of motion (shoulder abduction) without pain was 174.2 degrees with sham taping and 184.43 degrees with KT (2 RCTs, 68 participants), with an absolute improvement of 5.7% (95% CI 8.9% worse to 20.3% better) and a relative improvement of 6% (95% CI 10% worse to 22% better) at two weeks. No studies reported global assessment of treatment success. Quality of life was reported by one study but data were disaggregated in subscales. No reliable estimates for adverse events (4 studies; very low-certainty) could be provided due to the heterogeneous description of events in the sample. Comparison with conservative treatments Due to very low-certainty evidence, we are uncertain if KT improves overall pain, function, pain on motion and active range of motion compared with conservative treatments. However, KT may improve quality of life (low certainty of evidence).  Mean overall pain (0 to 10 scale, 0 no pain) was 0.9 points with conservative treatment and 0.46 points with KT (5 RCTs, 266 participants), with an absolute improvement of 4.4% (95% CI 13% better to 4.6% worse) and a relative improvement of 15% (95% CI 46% better to 16% worse) at six weeks. Mean function (0 to 100 scale, 0 better function) was 46.6 points with conservative treatment and 33.47 points with KT (14 RCTs, 499 participants), with an absolute improvement of 13% (95% CI 24% better to 2% better) and a relative improvement of 18% (95% CI 32% better to 3% better) at four weeks. Mean pain on motion (0 to 10 scale, 0 no pain) was 4 points with conservative treatment and 3.94 points with KT (6 RCTs, 225 participants), with an absolute improvement of 0.6% (95% CI 7% better to 8% worse) and a relative improvement of 1% (95% CI 12% better to 10% worse) at four weeks. Mean active range of motion (shoulder abduction) without pain was 156.6 degrees with conservative treatment and 159.64 degrees with KT (3 RCTs, 143 participants), with an absolute improvement of 3% (95% CI 11% worse to 17 % better) and a relative improvement of 3% (95% CI 9% worse to 14% better) at six weeks.  Mean of quality of life (0 to 100, 100 better quality of life) was 37.94 points with conservative treatment and 56.64 points with KT (1 RCTs, 30 participants), with an absolute improvement of 18.7% (95% CI 14.48% better to 22.92% better) and a relative improvement of 53% (95% CI 41% better to 65% better) at four weeks.  No studies were found for global assessment of treatment success. No reliable estimates for adverse events (7 studies, very low certainty of evidence) could be provided due to the heterogeneous description of events in the whole sample.

AUTHORS' CONCLUSIONS

Kinesio taping for rotator cuff disease has uncertain effects in terms of self-reported pain, function, pain on motion and active range of motion when compared to sham taping or other conservative treatments as the certainty of evidence was very low. Low-certainty evidence shows that kinesio taping may improve quality of life when compared to conservative treatment. We downgraded the evidence for indirectness due to differences among co-interventions, imprecision due to small number of participants across trials as well as selection bias, performance and detection bias. Evidence on adverse events was scarce and uncertain. Based upon the data in this review, the evidence for the efficacy of KT seems to demonstrate little or no benefit.

The influence of psychosocial factors on patient-reported outcome measures in rotator cuff tears pre- and post-surgery: a systematic review

PURPOSE

Recent research shows that major levels of psychological distress correlate with higher pain and reduced function in patients with shoulder and rotator cuff pathology. A systematic review updating a review published in 2016 was conducted to determine the degree of consistency and the strength of association between psychosocial factors and patient-reported outcomes (PROMs) in patients with rotator cuff repair (RCR) with new high-quality literature.

METHODS

The bibliographic searches were conducted from May to June 2020 within the following databases: MEDLINE/PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, and Web of Science. The articles included should discuss the association between psychosocial factors and outcomes in patients with documented or diagnosed rotator cuff tears through clinical and/or radiological examination. The Methodological Index for Non-Randomized Studies (MINORS) tool was used to assess the methodological quality.

RESULTS

Fifteen articles were included. Negative psychosocial factors were found consistently associated with worse function and disability in the pre- and post-operative period. In particular, psychosocial factors regarding emotional or mental health were associated with a weak to a substantial degree with preoperative and postoperative function/disability and pain intensity in patients undergoing RCR.

CONCLUSION

In patients undergoing repair of the rotator cuff tear, there was a correlation between poor psychological function before surgery and worsening post-surgical outcomes, such as persistence of postoperative pain intensity and worse levels of function/disability.

The impact of Charlson and Elixhauser comorbidities on patient outcomes following shoulder arthroplasty

AIMS

To investigate the impact of the Charlson and Elixhauser comorbidity indices on patient-reported outcomes measures (PROMs) following shoulder arthroplasty.

METHODS

Patients undergoing total shoulder arthroplasty (TSA), reverse shoulder arthroplasty (RSA), or hemiarthroplasty (HA) from 2016 to 2018 were identified, along with the Charlson and Elixhauser comorbidities listed as their secondary diagnoses in the electronic medical records. Patients were matched to our institution's registry to obtain their PROMs, including shoulder-specific (American Shoulder and Elbow Society (ASES) and Shoulder Activity Scale (SAS)) and general health scales (12-Item Short Form Survey (SF-12) and Patient-Reported Outcomes Measurement Information System-Pain Interference). Linear regression models adjusting for age and sex were used to evaluate the association between increasing number of comorbidities and PROM scores. A total of 1,817 shoulder arthroplasties were performed: 1,017 (56%) TSA, 726 (40%) RSA, and 74 (4%) HA. The mean age was 67 years (SD 10), and 936 (52%) of the patients were female.

RESULTS

The most common comorbidities were obesity (1,256, 69%) and hypertension (990, 55%). Patients with more comorbidities had lower ASES and SAS scores at baseline (p < 0.001). Elixhauser comorbidities continued to negatively impact ASES and SAS scores at one year (p = 0.002) and two-year follow-up (p = 0.002). Patients with more comorbidities reported greater pain interference on PROMIS at baseline (p = 0.007), but not at two years. Higher number of Charlson comorbidities were associated with lower scores on the SF-12 mental component at baseline (p < 0.001) and two years (p = 0.020). Higher number of Elixhauser comorbidities were associated with lower SF-12 physical component scores at baseline (p < 0.001) and two years (p = 0.004).

CONCLUSION

Higher number of comorbidities was associated with lower baseline scores and worse outcomes on both shoulder-specific and general health PROMs. The presence of specific comorbidities may be used during shared decision-making to manage expectations for patients undergoing shoulder arthroplasty.

Does the timing of surgical intervention impact the clinical outcomes and overall duration of symptoms in frozen shoulder?

BACKGROUND

The optimal timing of arthroscopic capsular release in patients with frozen shoulder is controversial. Some surgeons delay surgery in the belief that early surgical intervention results in a poorer prognosis. However, whether early surgical intervention causes inferior clinical outcomes and a longer duration of symptoms in frozen shoulder remains unclear. The objective of this study was to compare the clinical outcomes and overall duration of symptoms in frozen shoulder between patients who underwent early surgical intervention and those subjected to late surgical intervention. Our hypotheses were that (1) early surgical intervention would provide significant improvement in symptoms but inferior clinical outcomes because of more severe synovitis compared with late surgical intervention and (2) early surgical intervention would shorten the overall duration of symptoms compared with late surgical intervention.

METHODS

We reviewed 60 consecutive patients with frozen shoulder who underwent arthroscopic capsular release. We compared clinical outcomes and the overall duration of symptoms between 2 groups: Group I comprised 27 patients who underwent surgery <6 months after onset (mean, 3.8 months), whereas group II comprised 33 patients who underwent surgery ≥6 months after onset (mean, 11.1 months). The severity of glenohumeral synovitis at the time of surgery was evaluated. Patient-reported pain, shoulder function, and range of motion, as well as the presence of sleep disturbance, were assessed preoperatively and at 3 and 6 months after surgery.

RESULTS

Both groups showed significant improvements in the visual analog scale pain score, Japanese Orthopaedic Association score, American Shoulder and Elbow Surgeons score, and prevalence of sleep disturbance after surgery (P < .001), although the glenohumeral synovitis score was significantly higher in group I than in group II (P < .0001). Forward flexion at 6 months after surgery was significantly greater in group I than in group II (P = .007). The overall duration of symptoms was shorter in group I than in group II (P < .0001). Neither the pain score, functional score, prevalence of sleep disturbance, nor postoperative recovery time differed between groups.

CONCLUSIONS

Arthroscopic capsular release provided significant pain relief and improvement in shoulder function in patients with frozen shoulder regardless of the timing of surgery. Early surgical intervention might shorten the overall duration of symptoms in frozen shoulder and is not associated with inferior clinical outcomes when compared with late surgical intervention. Surgeons do not need to delay surgical intervention for patients who have intolerable pain and/or nocturnal pain with sleep disturbance.

How does rerupture affect sleep and quality of life in patients undergoing arthroscopic rotator cuff repair?

Background/aim

Sleep disturbance and related improvement in quality of life as a result of arthroscopic repair in rotator cuff tear (RCT) patients can be considered as an important parameter. The aim of our study is to evaluate the rotator cuff by ultrasonography (USG) in the first postoperative year and to examine whether there is a difference between sleep disturbance and quality of life between cases of rupture and healthy patients. In addition, we aim to compare the preoperative and at least the first postoperative year’s sleep disturbances and quality of life among patients who underwent arthroscopic RCT repair and to examine the effects of factors affecting this situation.

Materials and methods

We retrospectively reviewed the records of patients who were operated on for RCT. In this process, 257 patients were examined and 76 patients who met the inclusion criteria were included in the study. The Pittsburgh sleep quality index (PSQI), Constant–Murley shoulder score (CSS), and Oxford shoulder score (OSS) were used to evaluate the results preoperatively and at the last control visit of each patient. In the USG performed in the postoperative first year, the rotor cuff was evaluated in terms of rerupture.

Results

It was observed that 14 (18.4%) patients’ rotor cuffs were reruptured and those of 62 (81.6%) patients were intact. The preoperative PSQI, CSS, and OSS values of the patients were calculated as an average of 10.79 ± 3.58, 35.61 ± 8.88, and 17.61 ± 4.20 and the mean postoperative values were calculated as 5.45 ± 1.68, 81.55 ± 5.27, and 38.05 ± 3.06, respectively. The postoperative PSQI value was statistically significantly lower in patients with tears of <1 cm (PSQI: 4.29 ± 0.73) than in those with tears of 1–3 cm (PSQI: 5.50 ± 2.17) and 3–5 cm (PSQI: 5.88 ± 1.25) (P < 0.001). The mean CSS and OSS values were significantly higher in postoperative measurements for all tear types. According to the size of the tear, postoperative CSS and OSS values were statistically significantly lower in patients with tears of 3–5 cm (CSS: 78.59 ± 4.50 and OSS: 36.18 ± 2.47) than those with <1 cm (CSS: 85.43 ± 2.14 and OSS: 40.57 ± 1.55) and 1–3 cm (CSS: 83.21 ± 5.35 and OSS: 39.07 ± 2.94) tears (P < 0.001).

Conclusion

In the USG performed in the postoperative first year, it was determined that the patients with healthy rotator cuffs recovered better than those with rerupture.

Effects of Anxiety and Depression Measured via the Hospital Anxiety and Depression Scale on Early Pain and Range of Motion After Rotator Cuff Repair

BACKGROUND

Preoperative anxiety and depression are independent predictors of clinical outcomes after arthroscopic rotator cuff repair. However, few studies have evaluated correlations between outcomes such as pain and range of motion (ROM) after arthroscopic rotator cuff repair and preoperative anxiety and depression.

PURPOSE

To evaluate the effects of preoperative anxiety and depression, measured using the Hospital Anxiety and Depression Scale (HADS), on early pain and ROM after rotator cuff repair.

STUDY DESIGN

Cohort study; Level of evidence, 2.

METHODS

A total of 144 consecutive patients who underwent arthroscopic rotator cuff repair were enrolled and divided into 2 groups according to HADS scores: group A, those with a healthy psychological status (n = 103; anxiety ≤7 and depression ≤7), and group B, those with psychological distress (n = 41; anxiety ≥8 or depression ≥8). Clinical outcomes were assessed using the visual analog scale for pain (pVAS) and ROM at 3 and 6 months postoperatively and annually.

RESULTS

There were no significant preoperative differences in age, sex, tear size, pVAS scores, and ROM. However, at 3 months postoperatively, group A showed significantly lower mean pVAS scores (2.2 ± 1.3 vs 3.4 ± 1.8, respectively; P = .001) and significantly higher mean forward flexion (146.4°± 23.0° vs 124.1°± 28.2°, respectively; P < .001) than group B, as well as significantly higher mean levels of internal rotation at the back (T11.5 ± 2.8 vs L1.9 ± 2.5, respectively; P < .001) and significantly higher mean external rotation (42.4°± 15.9° vs 35.2°± 16.8°, respectively; P = .019). At 6 months postoperatively, the mean pVAS score was still significantly lower in group A than in group B (0.8 ± 1.6 vs 1.8 ± 2.1, respectively; P = .016), but other ROM measurements had no significant differences. There was also no significant difference in clinical and functional outcomes at the final follow-up.

CONCLUSION

Anxiety and depression negatively affected clinical outcomes after rotator cuff repair. Recovery from pain and of ROM after arthroscopic rotator cuff repair occurred more quickly in patients with a healthy psychological status. Therefore, assessments of preoperative psychological status should be emphasized to improve early clinical outcomes after arthroscopic rotator cuff repair.

Risk factors for sleep disturbance in patients with cervical myelopathy and its clinical significance: a cross-sectional study

BACKGROUND CONTEXT

Sleep disturbance is highly prevalent in patients with spinal cord injury and is one of the most important clinical issues affecting their quality of life. However, it has not been properly measured or treated in patients with cervical myelopathy (CM), although most typical or atypical symptoms of CM are known to be risk factors for sleep disturbance. In addition, previous studies identified that the presence of sleep disturbance is unintentionally missed under the current evaluation process for degenerative spinal disease without direct investigation using validated tools for sleep. Therefore, studies about sleep disturbances in patients with CM are essential.

PURPOSE

The purpose of this study was to investigate the prevalence of sleep disturbance in patients with CM using validated tools and to understand its mechanism by identifying high-risk patients.

STUDY DESIGN/SETTING

Cross-sectional study.

PATIENT SAMPLE

Consecutive patients diagnosed with CM.

OUTCOME MEASURES

Pittsburgh sleep quality index.

METHODS

This study was performed on patients diagnosed with CM. Sleep disturbance was determined using the Pittsburgh sleep quality index. Variables associated with sleep disturbance including demographics, lifestyle, medical history, and radiologic parameters were investigated. Independent risk factors related to sleep disturbance were identified using multivariate logistic regression analysis.

RESULTS

A total of 203 patients with CM were included in our study. Among them, 126 patients (62.1%) were men, and the mean age was 63.0 years. Despite male predominance, sleep disturbance was identified in 71.4% of patients (145 of 203). Multivariate analysis identified a worse depression scale score, a lower modified Japanese Orthopedic Association score, chronic shoulder joint pain, smaller spinal cord area, and decreased cervical range of motion as independent risk factors for sleep disturbance.

CONCLUSIONS

In patients with CM, sleep disturbance was associated with a more severe type of myelopathy. Further studies including polysomnography and measurement of melatonin will be helpful to identify the mechanisms of the sleep disturbance in patients with CM and to improve their quality of life and clinical outcomes.

Prevalence and Associated Factors of Depressive Symptoms Among Patients With Chronic Low Back Pain: A Cross-Sectional Study

Background: Few studies have focused on depressive symptoms among patients with chronic low back pain in China. The aim of this cross-sectional study was to assess the prevalence and associated factors of depressive symptoms in patients with chronic low back pain. Methods: From May to August 2021, 1,172 patients with chronic low back pain were recruited in China. Depressive symptoms were assessed through the Patient Health Questionnaire. Associations of demographic characteristics, clinical characters and social-psychological factors with depressive symptoms were investigated among patients with chronic low back pain. Results: The prevalence of depressive symptoms was 25.00%. Logistic regression analysis found that duration of pain in 1-5 years (1-3 years: OR = 2.91, 95%CI: 1.65-5.14, 3-5 years: OR = 3.09, 95%CI: 1.55-6.15) and more severe pain (OR = 1.13, 95%CI: 1.10-1.17) were associated with higher risks of depressive symptoms. Better family function (good family function: OR = 0.25, 95%CI: 0.15-0.41, moderate family dysfunction: OR = 0.47, 95%CI: 0.29-0.77) and higher pain self-efficacy (OR = 0.94, 95%CI: 0.93-0.95) were associated with lower risks of depressive symptoms. Conclusion: Patients with chronic low back pain have a high prevalence of depressive symptoms in China. Duration of pain, pain severity, family function and pain self-efficacy were predictors of depressive symptoms among chronic low back pain patients in China. Early identification of the associated factors may be helpful for the timely management of depressive symptoms.

Systematic Review of Sleep Quality Before and After Arthroscopic Rotator Cuff Repair: Are Improvements Experienced and Maintained?

Background:

Poor sleep quality is prevalent among patients with rotator cuff tears (RCTs) and negatively influences the potential for healing and quality of life. However, there is a paucity of literature describing the magnitude and timing of changes in sleep quality after arthroscopic rotator cuff repair (RCR).

Purpose:

(1) To evaluate the prevalence of poor sleep quality in patients undergoing arthroscopic RCR and (2) to determine the timing and magnitude of changes in sleep quality after RCR.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

PubMed, OVID/Medline, and Cochrane databases were queried in January 2020 for literature investigating the prevalence of poor sleep quality in patients with RCTs or changes in sleep quality after arthroscopic RCR. Data pertaining to study characteristics, risk of bias, sleep quality assessments, and clinical outcomes were extracted. A qualitative analysis of the prevalence of poor sleep quality and changes in sleep quality was performed.

Results:

A total of 8 studies (1034 patients) were included. The mean Pittsburgh Sleep Quality Index (PSQI) ranged from 5.2 to 15.0 preoperatively among all studies, while the frequency of patients experiencing poor sleep quality ranged from 40.8% to 89.0% in 4 studies. Four studies reported the mean PSQI at a minimum of 6 months postoperatively, which ranged from 4.2 to 7.1. Four studies did not report the PSQI score or the proportion of patients who experienced poor postoperative sleep quality. One study evaluated the PSQI at 12 months postoperatively, which decreased to 4.2 from 5.8 at 6 months. One study evaluated the PSQI at 24 months postoperatively, which decreased to 5.5 from 6.2 at 6 months.

Conclusion:

Patients with RCTs have a high prevalence of poor sleep quality. Consistent improvements in sleep quality are observed in the 6 months after arthroscopic RCR, but there is limited evidence based on the available data to characterize changes in sleep quality beyond this time. More evidence is needed to characterize changes in sleep quality beyond 6 months and how these changes are perceived by this patient population.

Influence of mental health on postoperative outcomes in patients following biceps tenodesis

PURPOSE

To evaluate the relationship between preoperative mental health measured by the Short-Form 12 health survey mental component score and outcomes after isolated biceps tenodesis.

METHODS

The American Shoulder and Elbow Surgeons form (ASES), Single Assessment Numeric Evaluation (SANE), Constant-Murley score (CMS), and visual analog scale (VAS) for pain were administered preoperatively and at 6 and 12 months postoperatively to consecutive patients undergoing isolated biceps tenodesis between 2014 and 2018. Minimal clinically important difference, substantial clinical benefit (SCB), patient-acceptable symptom state (PASS), and rates of achievement were calculated. Patients were stratified by mental health status based on preoperative scores on the Short-Form 12 health survey mental component score. Multivariate logistic regression was performed to evaluate preoperative mental health status on achievement of minimal clinically important difference, SCB, and PASS.

RESULTS

Patients demonstrated significant improvements in all outcome measures (P < .001). Patients with depression reported inferior postoperative scores on all patient-reported outcome measures. Low preoperative mental health score significantly predicted reduced likelihood to achieve SCB (odds ratio [OR]: 0.38, 95% confidence interval [CI]: 0.17-0.81, P = .01) and PASS (OR: 0.28, 95% CI: 0.12-0.65, P = .003) on the ASES form, SANE (OR: 0.24, 95% CI: 0.10-0.61, P = .003), CMS (OR: 0.25, 95% CI: 0.08-0.77, P = .016), and VAS pain (OR: 0.01, 95% CI: 0.00-0.31, P = .008).

CONCLUSION

Patients with depression reported inferior scores on all postoperative patient-reported outcome measures and demonstrated lower odds of achieving the SCB and PASS on the ASES form and PASS on the SANE, CMS, and VAS pain, compared with nondepressed patients.

Increased Health Care Costs and Opioid Use in Patients with Anxiety and Depression Undergoing Rotator Cuff Repair

PURPOSE

To (1) quantify the prevalence of mood disorders in patients undergoing arthroscopic rotator cuff repair (RCR) by use of a large claims database and (2) compare opioid use and medical costs in the year before and the year after RCR between patients with and without comorbid mood disorders.

METHODS

A large claims database was queried to identify patients who underwent arthroscopic RCR (Current Procedural Terminology code 29827) between October 2010 and December 2015. All patients were then screened for insurance claims relating to either anxiety or depression. We compared net costs and opioid use both 1 year preoperatively and 1 year postoperatively between patients with and without mood disorders by use of an analysis of covariance.

RESULTS

A total of 170,329 patients (97,427 male patients [57.2%] and 72,902 female patients [42.8%]) undergoing arthroscopic RCR were identified. Of the 170,329 patients, 46,737 (27.4%) had comorbid anxiety or depression, and after adjustment for preoperative cost, sex, age, and both preoperative and postoperative opioid use, the 1-year postoperative cost was 7.05% higher for those with a preoperative mood disorder than for those without a mood disorder. In addition, opioid use both in the 180 days prior to surgery (36.7% vs 26.9%) and more than 90 days after surgery (33.0% vs 27.2%) was substantially greater in the group with comorbid depression or anxiety.

CONCLUSIONS

In patients with comorbid mood disorders, opioid use and health care costs were increased both preoperatively and postoperatively. The increased cost in this patient population is estimated at $62.3 million annually. In an effort to provide high-quality, value-based care, treatment strategies should be developed to identify these patients preoperatively and provide the appropriate resources needed to improve the probability of a successful surgical outcome.

LEVEL OF EVIDENCE

Level III, retrospective, comparative therapeutic study.
