Anxiety disorders and adhesive capsulitis: a bidirectional Mendelian randomization study

Background

Previous epidemiological investigations and related research efforts consistently have outlined an observable association between anxiety disorders and adhesive capsulitis (AC). However, the intricate nature of the causal connection between these entities has yet to be fully clarified. Therefore, this investigative study aims to thoroughly examine and delineate the causal interrelationship between anxiety disorders and AC using a bidirectional, two-sample Mendelian randomization (MR) approach.

Methods

To pursue this inquiry, datasets related to anxiety disorders and AC were meticulously obtained from a publicly accessible genomewide association study. Instrumental variables, in the form of single nucleotide polymorphisms, were subsequently identified, undergoing a rigorous screening process that included intensity adjustment and the amelioration of linkage disequilibrium. The primary analytical tool for scrutinizing causal ramifications was the inverse variance weighting (IVW) methodology, complemented by supplementary analytical techniques such as weighted median, MR-Egger, simple mode, and weighted mode. Additionally, evaluations of heterogeneity and pleiotropy were meticulously conducted. Heterogeneity was assessed using Cochran's Q-test in conjunction with the IVW and MR-Egger methods, while pleiotropy was appraised through the MR-Egger intercept and MR-PRESSO analysis methods. A leave-one-out analysis was undertaken to enhance the reliability of our findings. Finally, AC was utilized to infer reverse causality concerning the risk of anxiety disorders.

Results

The random effects IVW analysis results yielded statistical significance (P = 9.362 × 10-6), demonstrating a causal link between anxiety disorders and elevated susceptibility to AC, reflected in an odds ratio of 1.267 (95% confidence interval: 1.141-1.407). Conversely, the inverse MR analysis predominantly produced null findings. Furthermore, sensitivity analyses underscored the robustness of our conclusions.

Conclusion

In summary, our meticulously conducted study unequivocally supports the presence of a causal connection between anxiety disorders and an increased propensity for AC. Unfortunately, the reverse MR analysis failed to provide compelling evidence indicative of a reciprocal genetic causative relationship between AC and anxiety disorders.

Perspectives, perceptions, and expectations of subjects with frozen shoulder: a web-based Italian survey

Introduction

Frozen shoulder (FS) is a musculoskeletal disorder affecting the glenohumeral joint. This condition leads to disability and a worsening in quality of life. Despite its considerable impact on patients and its economic burden, research on the psychological and social implications of FS-as well as patients' perspectives and needs-is limited. This study aims to explore the perspectives, perceptions, and expectations of individuals suffering from FS, providing a comprehensive understanding of their experiences and needs.

Methods

A cross-sectional observational study was conducted following STROBE guidelines. A 59-question survey was administered to Italian individuals diagnosed with FS from April 1 to July 1, 2023.

Results

All 110 participants completed the survey. Most preferred an experienced and empathetic physiotherapist (73.64%) and relied primarily on physiotherapy (49.09%) for FS management. Additionally, 45.45% were open to a multidisciplinary approach. Subjects reported reducing night pain (71.82%) and achieving full range of motion (ROM) recovery (70.91%) as their top priorities. Participants reported a notable shift in their mood from "pre" to "post" FS, with many experiencing fear and catastrophizing thoughts and perceiving a lack of social support. Furthermore, 27.27% were open to cortisone use, while 25.45% considered electrophysical agents beneficial for managing the painful phase of FS.

Conclusion

These results underscore a strong preference for empathetic physiotherapists and the value of a multidisciplinary approach. Addressing night pain and restoring ROM are crucial priorities-emphasizing the need for tailored and shared decision-making. Additionally, these findings highlight the importance of addressing psychological well-being alongside physical symptoms.

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.

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.

Psychological risk factors for the occurrence of frozen shoulder after rotator cuff repair

INTRODUCTION

Frozen shoulder is a dreaded complication after rotator cuff repair.

HYPOTHESIS

There are psychological determinants for this complication.

MATERIALS AND METHODS

We prospectively included 77 consecutive patients who underwent arthroscopic rotator cuff repair between May 2018 and April 2019. Along with a functional evaluation, we determined the Constant score, anxiety and depression levels based on the HADS, and kinesiophobia based on the Tampa Scale preoperatively and 6months after the surgery.

RESULTS

At the 6-month follow-up, 8 patients had been diagnosed with frozen shoulder (group A), 65 patients had satisfactory joint range of motion (group B) and 4 were lost to follow-up. In the frozen shoulder group, the preoperative anxiety rate was significantly higher than in group B (50% versus 17%, p=0.04). Furthermore, there were significantly more women (p=0.028) and more patients with an occupational disease in group A (75% versus 18%, p=0.027). At 6months postoperative, the Constant score was 55 in the group with a frozen shoulder versus 72 in group B (p=0.004). Neither depression nor kinesiophobia were risk factors for the development of frozen shoulder after rotator cuff repair.

CONCLUSION

Preoperative anxiety, the female sex and occupational disease are all risk factors for the occurrence of frozen shoulder after rotator cuff repair. Knowing these predisposing factors will help us better manage at-risk patients.

The Relationship between Depression or Anxiety Symptoms and Objective and Subjective Symptoms of Patients with Frozen Shoulder

Background

the aim of this study is to evaluate the prevalence and effect of depression and anxiety on the shoulder range of motion, as well as the objective and subjective symptoms in patients suffering from frozen shoulder.

Methods

Between 2013 and 2014, in a cross-sectional study, we evaluated 120 patients with idiopathic frozen shoulder. We collected the demographic data for each patient and measured shoulder range of motion in four directions in both limbs. All patients filled out visual analog scale (VAS) for pain and the disabilities of the arm, shoulder, and hand (DASH) questionnaires. Both Hamilton anxiety and depression questionnaires were filled out for each patient.

Results

A total of 92 patients (77%) with idiopathic frozen shoulder showed symptoms of depression, while only 32 (27%) of them experienced anxiety. Thirty-two patients (27%) showed symptoms of both depression and anxiety. Although elevation and abduction were not affected by depression, internal and external rotations were more restricted among patients who had symptoms of depression. DASH and VAS scores were higher in patients with symptoms of depression. In terms of anxiety, only VAS and DASH were different between two groups. In multivariable analysis, DASH score was correlated with severity of both anxiety and depression symptoms.

Conclusion

While there is no definitive relationship between symptoms of depression or anxiety and shoulder range of motion in patients suffering from frozen shoulder, patients who suffer from depression or anxiety experienced increased pain and limb disability.

Pain, depression and the postoperative stiff shoulder

Background

The surgical repair of shoulder pathologies, including rotator cuff disease and acromio-clavicular joint arthritis, have undergone many technical advances. However the debilitating postoperative stiff shoulder remains a common and significant complication of these surgeries, occurring in 4.9 to 23.2 % of patients undergoing rotator cuff repairs.

The pathology of the pathological postoperative stiff shoulder and its associated condition “frozen shoulder” are poorly understood and both lack formal objective clinical diagnostic criteria. Additionally, although factors associated with the development of idiopathic frozen shoulder have been well described, multiple studies looking at predictors of postoperative stiff shoulder have produced conflicting results. It has been hypothesised that increased pain in the postoperative period, and depression may be predictors of the development of postoperative stiff shoulder.

Method

A prospective cohort study involving 132 consecutive participants. Preoperatively, participants undergoing arthroscopic subacromial decompression and/or excision of the distal clavicle and/or rotator cuff repair will complete questionnaires about their levels of shoulder pain using a numerical rating scale from 0 to 10, and answer a Patient Health Questionnaire – 9 depression questionnaire. Postoperatively, the participants’ pain levels will be self-assessed at two, five and seven days and weeks four, seven and ten. They will complete the depression questionnaire twice, at the time of their routine first and final postoperative appointments with the treating surgeon. At the final appointment, approximately three months postoperatively, the treating surgeon will clinically diagnose participants as having a postoperative stiff shoulder or not. Their shoulders’ range of motion will be measured. The incidence of postoperative stiff shoulder will be determined, both pain and depression will be analysed as predictors for its development and incidences determined by different objective criteria will be compared.

Discussion

This trial will add to clinical understanding of the postoperative stiff shoulder by providing further insight into the incidence of this condition following shoulder surgery and assessing whether perioperative pain and depression can be used as clinical predictors of postoperative stiff shoulder or markers for possible early intervention. This study will also allow the comparison of incidences determined by different objective criteria in the same cohort.

Frozen shoulder and the Big Five personality traits

BACKGROUND

In the past, several studies have suggested the existence of a "periarthritic personality" in patients with frozen shoulder. We conducted a study to determine differences in personality traits in patients with primary and secondary frozen shoulders.

MATERIALS AND METHODS

We prospectively evaluated 118 patients (84 women and 34 men; mean age, 53.8 years; SD 7.56) with a frozen shoulder. Of these patients, 48 had an idiopathic frozen shoulder and 70 had a secondary frozen shoulder. Personality traits were determined by the NEO Five-Factor Inventory (NEO-FFI) scale. This questionnaire measures the 5 major personality traits and is based on the norms determined in a neutral test situation for 2415 controls.

RESULTS

Compared with healthy controls, no differences in personality traits were found in patients with primary and secondary frozen shoulder, except for Conscientiousness and Extraversion, for which patients with secondary frozen shoulder scored significantly higher than healthy controls. Patients with primary frozen shoulder scored significantly higher on Openness to Experience than did patients with secondary frozen shoulder; on the other 4 Big Five personality traits, no significant differences were found between patients with primary and secondary frozen shoulder. More specifically, patients with idiopathic frozen shoulder did not score higher on the trait Neuroticism as would be expected from previous publications.

CONCLUSIONS

Our study results do not indicate that patients with an idiopathic frozen shoulder have a specific personality compared with healthy controls. Only a few differences were found in personality traits when the entire frozen shoulder group was compared with healthy controls and between patients with primary and secondary frozen shoulders. The results of this study suggest that these differences are not sufficient to speak about a specific "frozen shoulder personality."

[Physical therapy of frozen shoulder: literature review]

OBJECTIVE

To determine the efficacy of physical treatments in adhesive capsulitis of the shoulder by a systematic review of literature, attempting to perform a meta-analysis from randomised clinical trials.

METHOD

A systematic literature search was conducted to retrieve all randomised controlled trials of physical therapy such as physiotherapy and manipulation, but also arthrographic distension, mobilisation under general anaesthesia or nerve block, arthroscopic distension or arthrolysis, and intra-articular corticoid injections. The main outcome for meta-analysis was the restoration of range of movement between the sixth week and the third month.

RESULTS

Only 16 articles could be selected, and only three about capsular distension were included in a meta-analysis because of the heterogeneity of the criteria assessing the functional results and of the poor methodological value of most of the articles.

DISCUSSION

Some open studies stressed the value of daily manipulations and physiotherapy, intra-articular corticosteroid injections, but their quality was poor or limited. Nothing was written about antalgic drugs to facilitate joint mobilisation, and the use of a thoraco-brachial abduction device between exercises was only quoted. The most refractory cases might need more aggressive interventions: arthrographic distension with local anaesthesia and steroid injection; mobilisation under general or local anaesthesia, specially interscalene brachial plexus block; arthroscopic release. But there was no randomised controlled study comparing these three techniques and it seemed impossible to come to any conclusion about the superiority of one of them. The meta-analysis showed yet that capsular distension with intra-articular corticoid injections was better than corticoid injections alone.

CONCLUSION

This demonstrated the need of a consensus about the criteria of assessment, the time of evaluation, before assessing by randomised clinical trials of good quality their therapeutic value.

Idiopathic adhesive capsulitis. A prospective functional outcome study of nonoperative treatment

BACKGROUND

Idiopathic adhesive capsulitis is a commonly recognized but poorly understood cause of a painful and stiff shoulder. Although most orthopaedic literature supports treatment with physical therapy and stretching exercises, some studies have demonstrated late pain and functional deficits. The purpose of this study was to evaluate the outcome of patients with idiopathic adhesive capsulitis who were treated with a stretching-exercise program.

METHODS

Seventy-five consecutive patients (seventy-seven shoulders) with phase-II idiopathic adhesive capsulitis were treated with use of a specific four-direction shoulder-stretching exercise program and evaluated prospectively. The initial evaluation included the recording of a detailed medical and orthopaedic history and assessment of pain, range of motion, and function. The outcome evaluation included assessment of pain, range of motion, and function; completion of the Disabilities of the Arm, Shoulder, and Hand (DASH) Questionnaire; and completion of the Short Form-36 (SF-36) Health Survey. The mean duration of follow-up was twenty-two months (range, twelve to forty-one months). One patient died prior to the final evaluation, and three patients were lost to follow-up.

RESULTS

Sixty-four (90 percent) of the patients reported a satisfactory outcome. Seven (10 percent) were not satisfied with the outcome, and five (7 percent) underwent manipulation and/or arthroscopic capsular release. The outcomes of the patients who did not have manipulation or capsular release were evaluated. There were significant improvements in the scores for pain at rest (from a mean of 1.57 points before treatment to a mean of 1.16 points at the final evaluation; p < 0.001) and pain with activity (from a mean of 4.12 points before treatment to a mean of 1.33 points at the final evaluation; p < 0.0001). On the average, active forward elevation increased 43 degrees, active external rotation increased 25 degrees, passive internal rotation increased eight vertebral levels, and the glenohumeral rotation arc at 90 degrees of abduction increased 72 degrees (p < 0.00001). The number of "yes" responses to the Simple Shoulder Test increased from a mean of 4.1 (of a possible twelve) to a mean of 10.75 (p < 0.00001). Despite the significant improvements and the high rate of patient satisfaction, there were still significant differences in the pain and motion of the affected shoulder when compared with those of the unaffected, contralateral shoulder (p < 0.00001). At the final outcome evaluation, the DASH scores demonstrated limitations when compared with known population norms, whereas the profiles of the SF-36 were comparable with those of age and gender-matched control populations. Prior treatment with physical therapy and a Workers' Compensation claim or pending litigation were the only variables that were associated with the eventual need for manipulation or capsular release. Male gender and diabetes mellitus were associated with worse motion at the final evaluation. Patients with a greater severity of pain with activity at the initial evaluation had significantly lower DASH scores at the final evaluation, and patients with lower initial scores on the Simple Shoulder Test had comparatively lower scores on the Simple Shoulder Test at the outcome evaluation.

CONCLUSIONS

The vast majority of patients who have phase-II idiopathic adhesive capsulitis can be successfully treated with a specific four-direction shoulder-stretching exercise program. Although measurable limitations and deficiencies were noted at the outcome evaluation, these appeared to be acceptable to most of the patients and did not affect their general health status. Patients with more severe pain and functional limitations before treatment had relatively worse outcomes. More aggressive treatment such as manipulation or capsular release was rarely necessary, and the efficacy of early use of these treatments should be further studied.

Long-term effectiveness of translational manipulation for adhesive capsulitis

Long term effects of glenohumeral joint translational (gliding) manipulation on range of motion, pain, and function in patients with adhesive capsulitis were studied. Thirty-one patients underwent brachial plexus block followed by translational manipulation of the glenohumeral joint. Changes in range of motion and pain were assessed before manipulation with the patient under anesthesia, immediately after manipulation with the patient still under anesthesia, at early followup (5.3 +/- 3.2 weeks), and at long term followup (14.4 +/- 7.3 months). Passive range of motion increased significantly for flexion, abduction, external rotation, and internal rotation. Significant decreases in visual analog pain scores between initial evaluation and the followup assessments also occurred. Furthermore, Wolfgang's criteria score increased significantly between initial evaluation and followup assessments. Translational manipulation provides a safe, effective treatment option for adhesive capsulitis.

The diabetic frozen shoulder: arthroscopic release

Seventeen patients who were diabetics developed frozen shoulders which failed to respond to conservative management. They had persistent pain, stiffness, and limited function. An arthroscopic release was performed by progressively releasing the anterior structures from superior to inferior. Starting from the interval area we progressed to the anterior superior glenohumeral ligament, the intra-articular portion of the subscapularis, the anterior capsule, and the inferior capsule. Postoperatively physiotherapy was carried out daily to maintain the range of movement. At a follow up of 1 to 5 years the patients were assessed using the American Shoulder Society scheme. In addition the patients were assessed preoperatively and postoperatively on four criteria; pain, external rotation, abduction, and function. We found that the patients were statistically significantly improved in all four categories. Thirteen of the 17 patients had no pain, full range of motion compared with the opposite side, and full function. There was one poor result with no improvement. The remaining three patients had improved but still had residual abnormalities. We consider arthroscopic release to be an effective treatment for the resistant diabetic frozen shoulder.

Frozen shoulder: current concepts

The literature on frozen shoulder (FS) is reviewed. The etiology of FS is still not known and our understanding of the pathogenesis is limited. Studies on treatment programs under controlled conditions are few and incomplete. Further research is urgently needed.
