Frozen shoulder: subjects' needs and perspectives and clinicians' beliefs and management strategies: do they align? A cross-sectional study

OBJECTIVE

Physiotherapists (PTs) play a crucial role in managing individuals with Frozen Shoulder (FS), frequently being the first healthcare professionals involved in the treatment of this condition.

AIM

This study aimed to compare the beliefs, expectations, and perspectives of individuals with FS with the knowledge, skills, and strategies of PTs, highlighting similarities and differences.

METHOD

This study adhered to the Checklist for Reporting Results of Internet E-Surveys (CHERRIES). From May 1st to August 1st, 2023, a two-part survey was conducted involving PTs and individuals diagnosed with FS. The survey focused on comparing key areas such as clinical assessment, patient education, treatment expectations, and the psychological aspects of the patient-clinician relationship.

RESULTS

A total of 501 PTs and 110 subjects with FS participated in the survey. Most PTs showed proficiency in FS pathoanatomical conditions and were also attentive to psychological aspects (88.4%), describing the pathology evolution in three or two stages (68.2%). They also highlighted the importance of patient education (89.6%) and recognized the potential benefits of a multiprofessional collaboration in managing FS (82.2%). Reassurance was reported as a priority by 32.3% of PTs. Subjects with FS expressed a preference for PTs who are both expert and empathetic (73.6%). Regarding their understanding of FS, 29.09% of subjects reported receiving a three-phase explanation, while 26.36% felt inadequately informed. Nearly half of the subjects (49.09%) anticipated being managed independently by a PT, with 93.64% prioritizing the improvement of their range of motion.

CONCLUSION

This study revealed a general agreement between subjects with FS and PTs regarding aspects of the therapeutic relationship, patient education, pathology management, compliance and motivation strategies, and pain management preferences. However, significant differences emerged concerning the perception of physiotherapy effectiveness, primary treatment goals, subjects' priorities, and the importance of psychological assessment.

Study of Functional Outcome of Intra-articular Steroid Injection and Manipulation of Shoulder Joints in Frozen Shoulder

INTRODUCTION

Frozen shoulder, also known as adhesive capsulitis, is characterized by the insidious onset of pain and progressive loss of global active and passive mobility of the glenohumeral joint, which can be treated by non-surgical or surgical methods. This study was done to evaluate the functional outcome of intra-articular (I/A) steroid injection and manipulation of the shoulder joint manipulation under anesthesia (MUA) in frozen shoulder.

METHODS

A cross-sectional study was done in a tertiary care hospital in Pokhara, Nepal. A total of 35 patients over 40 years were included in the study. All the patients underwent I/A steroid injection and MUA. The functional outcome was evaluated using a Constant-Murley shoulder score (CSS) and a visual analogue scale (VAS) scoring system.

RESULT

The mean age was 53.46±7.524 years. Twenty-two were female, while 13 were male. Twelve patients were associated with diabetes. Minor complications were noted in 15 patients (14 with transient pain and one with facial flushing). At 12 weeks, the mean VAS score was 2.16±1.33 cm, and the mean CSS score was 82.66±7.008. At 24 weeks, the mean VAS was 1.534±1.195 cm, and the mean CSS score was 85.77±6.998.

CONCLUSION

This study shows that patients with frozen shoulder treated with I/A steroid injection and MUA give excellent functional outcomes in most patients.

Rehabilitation in subjects with frozen shoulder: a survey of current (2023) clinical practice of Italian physiotherapists

OBJECTIVE

Frozen Shoulder (FS) is a musculoskeletal pathology that leads to disability, functional decline, and a worsening in quality of life. Physiotherapists are the primary professionals involved in the treatment of FS, and it is essential to determine if their practice aligns with evidence-based suggestions.

AIM

The aim is to assess the knowledge, skills, and operational strategies of Italian physiotherapists regarding FS and compare them with the existing literature.

METHODS

A web-based, anonymous, and voluntary cross-sectional survey was developed and administered to Italian physiotherapists to evaluate their clinical practices.

RESULTS

A total of 501 physiotherapists (38.5% female), completed the survey. More than half were under 35 years old (67.8%), declared working in private practice settings or being self-employed (57.1%), and were primarily engaged with musculoskeletal patients (81.8%). For subjects with FS at their first access, 21.4% identified X-rays as the most useful imaging technique to recognize pathologies beyond rehabilitation competence. In terms of general management, the majority reported working with an orthopaedic or physiatrist (47.5%) or in a multidisciplinary team (33.5%). Regarding manual therapy techniques, 63.3% of physiotherapists preferred intense degree mobilization, posterior direction, and moderate pain at the end of the range of motion for low irritable/high stiffness FS; however, there is a lack of consensus for managing very irritable/low stiffness FS. The majority of physiotherapists (57.7%) concurred that stretching improves the balance between metalloproteinase and its inhibitors. Additionally, 48.3% of physiotherapists selected mobile phone videos and messages to improve patients' compliance with exercises at home and for motivational/educational purposes.

DISCUSSION AND CONCLUSION

The clinical practices of Italian physiotherapists in FS subjects sometimes deviate from evidence-based recommendations. While some discrepancies may be attributed to the existing uncertainties in the literature regarding knowledge and management strategies for FS patients, the authors recommend a stronger adherence to evidence-based practice.

The effect of muscle-biased manual therapy on shoulder kinematics, muscle performance, functional impairment, and pain in patients with frozen shoulder

BACKGROUND

Frozen shoulder (FS) is characterized by restricted active and passive shoulder mobility and pain.

PURPOSE

Compare the effect of muscle-biased manual therapy (MM) and regular physical therapy (RPT) in patients with FS.

STUDY DESIGN

Pretest-post-test control group study design.

METHODS

We recruited 34 patients with FS and compared the effect of 12-session MM and RPT. The outcome measures were scapular kinematics and muscle activation, scapular alignment, shoulder range of motion, and pain intensity. Two-way analysis of variance was used to examine the intervention effect with α = 0.05.

RESULTS

Both programs resulted in similar improvements in pain and shoulder function. Compared to the RPT, MM resulted in increased posterior tilt (MM: 7.04°-16.09°, RPT: -2.50° to -4.37°; p = 0.002; ES = 0.261) and lower trapezius activation (MM: 260.61%-470.90%, RPT: 322.64%-313.33%; p = 0.033; ES = 0.134) during scaption, and increased posterior tilt (MM: 0.70°-15.16°, RPT: -9.66° to -6.44°; p = 0.007; ES = 0.205) during the hand-to-neck task. The MM group also showed increased GH backward elevation (MM: 37.18°-42.79°, RPT: 43.64°-40.83°; p = 0.004, ES = 0.237) and scapular downward rotation (MM: -2.48° to 6.80°, RPT: 1.93°-1.44°; p < 0.001; ES = 0.404) during the thumb-to-waist task, enhanced shoulder abduction (MM: 84.6°-102.3°, RPT: 85.1°-92.9°; p = 0.02; ES = 0.153), and improved scapular alignment (MM: 10.4-9.65 cm, RPT: 9.41-9.56 cm; p = 0.02; ES = 0.114).

CONCLUSIONS

MM was superior to the RPT regarding scapular neuromuscular performance. Clinicians should consider adding muscle-biased treatment when treating FS.

Efficacy of hydrodistension for frozen shoulder: A systematic review and meta-analysis

BACKGROUND

The aim of this study was to provide comprehensive and reliable evidence for the treatment of pain and motor function in patients with frozen shoulder (FS) with hydrodistension.

METHODS

The research including randomized controlled trials (RCTs) for FS that compared hydrodistension with routine treatments to controls was searched and screened in the PubMed, Library of congress, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, China Science and Technology Journal Database. Constant-Murley score (CMS) for shoulder function and visual analog scale (VAS) for pain must be assessed. RevMan 5.3 software was used to evaluate the bias and quality of the included studies.

RESULTS

We found that analgesic effects (MD: -1.07; 95% CI: -1.94 to -0.20; P < .00001; I2 = 99%) and function (MD: 8.54; 95% CI: 3.35 to 13.71; P < .00001; I2 = 97%) were better in the groups where hydrodistension plus routine treatments were used to treat FS compared to other interventions.

CONCLUSION

The result suggests that hydrodistension is of great clinical significance in alleviating pain and improving function to patients with FS.

Capsule elongation occurs after first time shoulder dislocation A biomechanical in-vitro investigation on human cadaveric specimen

Purpose

As capsule elongation is assumed to weaken the static stability of the shoulder joint, the purpose of this biomechanical study was to demonstrate that capsule elongation occurs immediately after a first-time shoulder dislocation and not just after recurrent dislocation events. We hypothesize an increment in joint clearance due to joint capsule elongation after a first-time dislocation.

Methods

An experimental in-vitro study was conducted on 6 paired fresh frozen human shoulders (4 females; 2 males; 12 specimen) with a mean age of 80 (Range 67-89) years. The shoulder joint with the articular capsule was exposed and an inferior static tension force of 2.5 N was applied to the humerus prior to dislocation. Next, the humeral head was dislocated and was then immediately reduced back into the start position. The joint gap as well as joint capsule deformation was assessed using optical techniques.

Results

The radiographic joint gap increased from 13.7 ± 6.9 mm (prior to dislocation) to 18.1 ± 6.5 mm (post dislocation) (p < .001). The increase in joint clearance was 4.4 mm. The joint capsule elongated from 5.9 ± 0.005 % (prior to dislocation) to 9.4 ± 0.007 % (post dislocation) (p < .001). The mean increase in joint capsule elongation was 3.5 %.

Conclusions

Capsule elongation was observed immediately after a simulated first-time shoulder dislocation in an in-vitro model of elderly human cadavers. It might therefore not only be a phenomenon of recurrent dislocation events.

Psychometric properties of the Disability of Arm Shoulder and Hand (DASH) in subjects with frozen shoulder: a reliability and validity study

BACKGROUND

Frozen Shoulder (FS) is a painful condition characterized by severe pain and progressive restriction of shoulder movement, leading to functional impairment and reduced quality of life. While different Patient Reported Outcome Measurements (PROMs) tools exist for assessing shoulder diseases, few specific PROMs are validated for FS patients.

PURPOSE

This study aims to assess the psychometric properties of the Disability of Arm, Shoulder, and Hand (DASH) questionnaire in FS patients.

METHODS

One hundred and twenty-four subjects (mean ± SD age = 55.4 ± 7.9 years; 55.6% female) diagnosed with FS were included and completed the DASH questionnaire, the Numerical Pain Rating Scale (NPRS), the Shoulder Pain and Disability Index (SPADI), and the Short-Form Health Survey 36 (SF-36). Floor or ceiling effects were investigated. Structural validity was analysed through a unidimensional Confirmatory Factor Analysis (CFA), internal consistency through Cronbach's alpha, test-retest reliability through the Intraclass Correlation coefficient (ICC), measurement error through the Standard Error of Measurement (SEM), and the Minimum Detectable Change (MDC), and construct validity through the hypothesis testing with the correlation with the other outcome measures used.

RESULTS

No floor or ceiling effects were observed. CFA confirmed a one-factor structure after addressing local item dependency (Root Mean Square Error of Approximation = 0.055; Standardized Root Mean Square Residual = 0.077; Comparative Fit Index = 0.970; Tucker-Lewis Index = 0.968). Cronbach's alpha was high (= 0.951), and test-retest reliability was excellent (ICC = 0.999; 95% CI: 0.998-1.000). SEM was equal to 0.5 points, and MDC to 1.5 points. Construct validity was considered satisfactory as 80% of the a-priori hypotheses were met.

CONCLUSION

The DASH questionnaire demonstrated good psychometric properties in FS patients, supporting its use as a valuable tool for assessing the impact of FS in clinical and research settings.

Improved range of motion after manipulation under anesthesia versus physiotherapy for stage two frozen shoulder: a randomized controlled trial

Background

Frozen shoulder (FS) is a common cause of shoulder pain and stiffness. Conservative treatment is sufficient for the majority of patients with long-term recovery of shoulder function. Manipulation under anesthesia (MUA) is known as a well-established treatment option if conservative treatment fails. It is unknown whether MUA does indeed shorten the duration of symptoms or leads to a superior outcome compared to conservative treatment. The objective of the current trial is to evaluate the effectiveness of MUA followed by a physiotherapy (PT) program compared to a PT program alone in patients with stage 2 FS.

Methods

A prospective, single-center randomized controlled trial was performed. Patients between 18 and 70 years old with stage 2 FS were deemed eligible if an initial course of conservative treatment consisting of PT and intra-articular corticosteroid infiltration was considered unsatisfactory. Patients were randomized, and data was collected with an online data management platform (CASTOR). MUA was performed by a single surgeon under interscalene block, and intensive PT treatment protocol was started within 4 hours after MUA. In the PT group, patients were referred to instructed physiotherapist, and treatment was guided by tissue irritability. The primary outcome was the Shoulder Pain and Disability Index (SPADI) score. Secondary outcomes were pain, range of motion (ROM), Oxford Shoulder Score, quality of life, and ability to work.

Results

In total, 82 patients were included, 42 in the PT group and 40 in the MUA group. There was a significant improvement in SPADI, Oxford Shoulder Score, pain, ROM, and quality of life in both groups at 1-year follow-up. SPADI scores at three months were significantly improved in favor of MUA. MUA showed a significantly bigger increase in anteflexion and abduction compared to PT at all points of follow-up. No significant differences between both groups were found for all other parameters. No fractures, dislocations, or brachial plexus injuries occurred in this trial.

Conclusion

MUA in stage 2 FS can be considered safe and results in a faster recovery of ROM and improved functional outcome, measured with SPADI scores, compared to PT alone in the short term. After 1 year, except for slightly better ROM scores for MUA, the result of MUA is equal to PT.

Continuous suprascapular nerve blockade to potentiate intensive rehabilitation for refractory adhesive shoulder capsulitis: a cohort study

PURPOSE

Evaluating the short- and long-term efficacy of a continuous ten day suprascapular nerve block combined with daily multidisciplinary rehabilitation on shoulder range of motion (ROM), pain, and function in patients with refractory adhesive capsulitis (AC).

METHODS

In this retrospective cohort study, patients admitted to a specialized pain clinic for refractory AC for more than 6 months underwent continuous suprascapular nerve blockade for ten days and received 2 hours of physiotherapy and occupational therapy daily. Standardized assessments were performed at baseline, at days three, six, ten, 30, 90, and 180, and included active and passive ROM measurements, the visual analog scale (VAS) for pain and the disabilities of the arm, shoulder and hand (DASH) questionnaire to assess pain, disability, and quality of life. Improvements over time were assessed using ANOVAs.

RESULTS

Thirty-two patients were followed (age: 52 ± 8 years, 25 females, mean symptoms duration of two years). There was a significant improvement in ROM for all amplitudes at day ten (short-term; range: 20-35°, p < 0.001) and at day 180 (long-term; range: 18-47°, p < 0.001). The pain and disability scores significantly reduced by day 180 (mean VAS reduction: 2.6 units, p < 0.001; mean DASH reduction: 9.5 points, p < 0.001).

CONCLUSION

Continuous SSNB combined with intensive multidisciplinary rehabilitation represents an efficient therapeutic option for patients with chronic AC who did not respond to conventional treatments.

Effectiveness of high-intensity laser therapy in the treatment of patients with frozen shoulder: a systematic review and meta-analysis

The purpose of this study is to evaluate the effects of high-intensity laser therapy (HILT) in patients with frozen shoulder. PRISMA guidelines were adhered to, and a systematic search was conducted in the PubMed, Web of Science, Scopus, CINAHL, Science Direct, and PEDro databases (last update: September 4, 2023; search period: December 2022-September 2023). The inclusion criteria encompassed RCTs comparing HILT with other physical therapy interventions in frozen patients with frozen shoulders, with or without sham HILT, assessing pain intensity, shoulder ROM, and disability outcomes. The quality of the RCTs was assessed with the Cochrane Risk of Bias tool, and evidence was assessed using the GRADE approach. Five trials met the eligibility criteria and were included in the review and meta-analysis, which pooled results from the visual analog scale (VAS), goniometry, and the shoulder pain and disability index (SPADI). Mean differences (MDs) for pain intensity and disability show a pooled effect in favor of HILT both for VAS (MD =  - 2.23 cm, 95% CI: - 3.25, - 1.22) and SPADI (MD =  - 10.1% (95% CI =  - 16.5, - 3.7), changes that are statistical (p < 0.01) and clinical. The MD for flexion (MD = 9.0°; 95% CI: - 2.36°, 20.3°; p = 0.12), abduction (MD = 3.4°; 95% CI: - 6.9°, 13.7°; p = 0.51), and external rotation (MD =  - 0.95°; 95% CI: - 5.36°, 3.5°; p = 0.67) does not show statistical and clinical differences between groups after treatment. PI and disability changes were graded as important due to their clinical and statistical results. HILT into a physical therapy plan reduce pain and disability, but it does not outperform conventional physical therapy in improving shoulder ROM. It is suggested that future RCTs compare the effects of HILT and LLLT to assess their possible differences in their analgesic effects.

Effect of Transfer Energy Capacitive and Resistive Therapy on Shoulder Pain, Disability, and Range of Motion in Patients With Adhesive Capsulitis: A Study Protocol for a Randomized Controlled Trial

Objective

We describe a protocol to evaluate the effectiveness of transfer energy capacitive and resistive (TECAR) therapy on shoulder passive range of motion, shoulder pain, and disability index in patients with adhesive capsulitis.

Methods

This study will be a double-blinded randomized clinical trial with a 1-month follow-up. For the purpose of this research, 30 patients with a 3-month history of shoulder pain and disability diagnosed as adhesive capsulitis will be selected and then randomized into 2 groups, including conventional physiotherapy consisting of electrophysical modalities and therapeutic exercises, which will be given to the control group. In the intervention group, after conventional physiotherapy, 10 minutes of TECAR therapy in resistive mode will be applied on both the anterior and inferior aspects of the shoulder joint. Outcome measures will be related to shoulder passive range of abduction, flexion, and external rotation that will be measured using a digital inclinometer, as well as shoulder pain and disability index that will be assessed by the validated questionnaire. Assessment will be done at baseline, 1 day after the intervention, and by passing 1 month.

Results

The statistical analysis will describe within-group and between-group comparisons; the findings will be illustrated in tables and charts.

Conclusion

Given the reason that the effectiveness of TECAR therapy has not been widely evaluated in adhesive capsulitis, the findings of this pilot study would provide baseline information on the effectiveness and complications of this treatment method and possibly propose a more appropriate protocol for patients with adhesive capsulitis.

Deficits in the thalamocortical pathway associated with hypersensitivity to pain in patients with frozen shoulder

Background and purpose

Frozen shoulder (FS) is a chronic pain condition and has been shown to be associated with pain sensitization. However, the underyling brain mechanisms remain unclear. Here, we aimed to explore brain alterations and their association with pain sensitization in patients with FS.

Materials and methods

A total of 54 FS patients and 52 healthy controls (HCs) were included in this study. Here, we applied both structural and functional magnetic resonance imaging (MRI) techniques to investigate brain abnormalities in FS patients. Voxel-wise comparisons were performed to reveal the differences in the gray matter volume (GMV) and amplitude of low-frequency fluctuation (ALFF) between FS patients and HCs. Furthermore, the region of interest (ROI) to whole-brain functional connectivity (FC) was calculated and compared between groups. Finally, Pearson's correlation coefficients were computed to reveal the association between clinical data and brain alterations.

Results

Four main findings were observed: (1) FS patients exhibited decreased thalamus GMV, which correlated with pain intensity and pain threshold; (2) relative to HCs, FS patients exhibited a higher level of ALFF within the anterior cingulate cortex (ACC) and the thalamus; (3) FS patients exhibited a significant increase in Tha-S1 FC compared to HCs; and (4) the effect of thalamus GMV on pain intensity was mediated by pain threshold in FS patients.

Conclusion

The dysfunctional thalamus might induce pain hypersensitivity, which further aggravates the pain in FS patients.

Traditional Chinese medicine for frozen shoulder: An evidence-based guideline

BACKGROUND

Frozen shoulder is a common disorder that can lead to long-lasting impairment in shoulder-related daily activities. Traditional Chinese medicine (TCM) has played an important role in the effort to manage frozen shoulder.

PURPOSE

We aimed to develop an evidence-based guideline for treating frozen shoulder with traditional Chinese medicine.

STUDY DESIGN

Evidence-based guideline.

METHODS

We developed this guideline based on internationally recognized and accepted guideline standards. The guideline development group used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to rate the certainty of evidence and the strength of recommendations. The benefits and harms, resources, accessibility, and other factors were fully taken into account, and the GRADE grid method was used to reach consensus on all recommendations.

RESULTS

We established a multidisciplinary guideline development panel. Based on a systematic literature search and a face-to-face meeting, nine clinical questions were identified. Finally, twelve recommendations were reached by consensus, comprehensively considering the balance of benefits and harms, certainty of evidence, costs, clinical feasibility, accessibility, and clinical acceptability.

CONCLUSION

This guideline panel made twelve recommendations, which covered the use of manual therapy, acupuncture, needle knife, Cheezheng Xiaotong plaster, Gutong plaster, exercise therapy and integrated TCM and Western medicine, such as combined modalities and corticosteroid injections. Most of them were weakly recommended or consensus based. The users of this guideline are most likely to be clinicians and health administrators.

Living with frozen shoulder. 'Here are the risks. I want the injection'. An interpretative phenomenological analysis

BACKGROUND

Frozen shoulder is a disabling condition characterised by severe pain and loss of shoulder movement and may affect up to 5% of the population. Qualitative research documents debilitating pain and how treatment to reduce pain is a priority for people diagnosed with frozen shoulder. Corticosteroid injections are a principal treatment to reduce the pain of frozen shoulder, however little is known about the patient experience.

OBJECTIVES

This study aims to address this gap in the knowledge by exploring the lived experience of people with frozen shoulder who have undergone an injection and to highlight other novel findings.

DESIGN

This is a qualitative study using interpretative phenomenological analysis. One-to-one, semi-structured interviews were conducted with seven people diagnosed with frozen shoulder who had received a corticosteroid injection as part of their management.

METHODOLOGY

A purposive sample of participants were interviewed via MSTeams™ due to Covid-19 restrictions. Data was collected through semi-structured interviews and analysed in accordance with interpretive phenomenological analysis methods.

RESULTS

Three group experiential themes were identified: the dilemma surrounding injections; the challenges of understanding the causes of frozen shoulder; the impact on self and others.

CONCLUSION

Participants conveyed a strong desire in seeking a corticosteroid injection whilst seemingly dismissing the risks. A novel concept was illuminated as frozen shoulder seemed inextricably linked with the ageing process, which negatively impacted body-image. The impact on others is driven by a sense of the unfamiliar nature of illness and it is incumbent on healthcare professionals to seek opportunities to explore the individual's beliefs.

Managing painful shoulder after neurological injury

Shoulder pain is common after neurological injury and can be disabling, lead to poor functional outcomes and increase care costs. Its cause is multifactoral and several pathologies contribute to the presentation. Astute diagnostic skills and a multidisciplinary approach are required to recognise what is clinically relevant and to implement appropriate stepwise management. In the absence of large clinical trial data, we aim to provide a comprehensive, practical and pragmatic overview of shoulder pain in patients with neurological conditions. We use available evidence to produce a management guideline, taking into account specialty opinions from neurology, rehabilitation medicine, orthopaedics and physiotherapy.

Effect of Functional Scapular Stabilization Training on Function and Pain in Frozen Shoulder Syndrome: A Randomized Controlled Trial

OBJECTIVE

The purpose of this study was to determine the effect of functional scapular stabilization training compared with the standard physical therapy on function and pain in people with frozen shoulder syndrome (FSS).

METHODS

In a single-blind randomized controlled trial, 86 people with FSS were randomly allocated into the intervention group (functional stabilization training [n = 43]) and control group (standard physical therapy [n = 43]) using block randomization for 12 weeks. The primary outcome measures were the Shoulder Pain and Disability Index and the numeric pain rating scale. The secondary outcome measures were range of motion (ROM), range of passive abduction, and coracoid pain test. All the outcome measures were carried out by an independent blind outcome assessor at baseline and at the end of 12 weeks.

RESULTS

A significant group × time interaction effect was observed for the Shoulder Pain and Disability Index (95% CI, 2.95-16.74; P < .01) and the numeric pain rating scale (95% CI, 0.67-2.07; P < .01) at the end of 12 weeks. The external rotation ROM showed a statistical significance with a mean change of 7.8° and P value of <.01.

CONCLUSION

The present findings show that scapular functional stabilization training resulted in improvement of function, reduction in pain, and greater improvement in external rotation ROM in patients with FSS. Also, our study findings suggest the involvement of rotator interval and inferior soft-tissue structures as indicated by the coracoid pain test and range of passive abduction.

Arthroscopic Pan-Capsular and Transverse Humeral Ligament Release with Biceps Tenodesis for Patients with Refractory Frozen Shoulder

Arthroscopic capsular release allows direct visualization and release of inflamed tissues in refractory frozen shoulder. The reticular neural network in the long head of the biceps tendon (LHBT) and nerve endings of the transverse humeral ligament (THL) might be responsible for shoulder pain. We hypothesized that patients with painful refractory frozen shoulder benefited from pan-capsular release, THL release, and LHBT tenodesis. The LHBT tenodesis decreased the possibility of LHBT instability. The balance of the shoulder joint was maintained after such extensive release. From October 2013 to June 2019, patients with painful refractory frozen shoulder were enrolled consecutively at the same institute. All patients received arthroscopic pan-capsular, THL release, and suprapectoral LHBT tenodesis with a minimum of 2-year follow-up. Preoperative and postoperative shoulder range of motion (ROM), pain visual analog scale (PVAS), subjective shoulder value (SSV), constant score, LHBT score, acromio-humeral distance (AHD), and critical shoulder angle (CSA) were recorded. In total, 35 patients with an average age of 53.1 ± 9 years were enrolled. The average follow-up period was 24 ± 1.5 months. Forward elevation improved from 105.1° ± 17° to 147° ± 12° (p < 0.001), external rotation improved from 24.1° ± 13.3° to 50.9° ± 9.7° (p < 0.001), and internal rotation improved from L3 to T9 (p < 0.001), respectively, at final follow-up. PVAS improved from 7.3 ± 1.1 to 1.8 ± 0.6 (p < 0.001), constant score from 23.4 ± 11 to 80.7 ± 5.2 (p < 0.001), and SSV from 27.7 ± 10.5 to 77.4 ± 3.8, respectively, at follow-up. No differences were found in AHD and CSA after surgery (p = 0.316, and p = 0.895, respectively). Patients with painful refractory frozen shoulder benefited from pan-capsular and THL release. A radiographically balanced shoulder joint was maintained even after such extensive release.

Musculoskeletal complications in patients with diabetes mellitus

Musculoskeletal conditions are common in patients with diabetes. Several musculoskeletal disorders are viewed as chronic complications of diabetes because epidemiological studies have revealed high correlations between such complications and diabetes, but the pathophysiological links with diabetes remains unclear. Genetic predispositions, shared risk factors, microvascular impairments, progressive accumulation of advanced glycation end-products, and diabetic neuropathy may underlie the development of musculoskeletal disorders. Musculoskeletal complications of diabetics have received less attention than life-threatening microvascular or macrovascular complications. Here, we review several diabetic musculoskeletal complications with a focus on the clinical importance of early recognition and management, which would improve quality of life and physical function.

Frozen shoulder

Frozen shoulder is a common debilitating disorder characterized by shoulder pain and progressive loss of shoulder movement. Frozen shoulder is frequently associated with other systemic conditions or occurs following periods of immobilization, and has a protracted clinical course, which can be frustrating for patients as well as health-care professionals. Frozen shoulder is characterized by fibroproliferative tissue fibrosis, whereby fibroblasts, producing predominantly type I and type III collagen, transform into myofibroblasts (a smooth muscle phenotype), which is accompanied by inflammation, neoangiogenesis and neoinnervation, resulting in shoulder capsular fibrotic contractures and the associated clinical stiffness. Diagnosis is heavily based on physical examination and can be difficult depending on the stage of disease or if concomitant shoulder pathology is present. Management consists of physiotherapy, therapeutic modalities such as steroid injections, anti-inflammatory medications, hydrodilation and surgical interventions; however, their effectiveness remains unclear. Facilitating translational science should aid in development of novel therapies to improve outcomes among individuals with this debilitating condition.

Non-Surgical and Rehabilitative Interventions in Patients with Frozen Shoulder: Umbrella Review of Systematic Reviews

Background

Frozen shoulder (FS) is a painful condition characterized by progressive loss of shoulder function with passive and active range of motion reduction. To date, there is still no consensus regarding its rehabilitative treatment for pain management.

Purpose

The aim of this umbrella review of systematic reviews was to analyze the literature, investigating the effects of non-surgical and rehabilitative interventions in patients suffering from FS.

Patients and Methods

A review of the scientific literature was carried out from 2010 until April 2020 using the following search databases: PubMed, Medline, PEDro, Scopus and Cochrane Library of Systematic Reviews. A combination of terms was used for the search: frozen shoulder OR adhesive capsulitis AND systematic review OR meta-analysis AND rehabilitation NOT surgery NOT surgical intervention. We included systematic reviews that specifically dealt with adults with FS, treated with non-surgical approaches. All the systematic reviews and meta-analyses included in the study that met the inclusion criteria were assessed using the Assessment of Multiple Systematic Reviews as a quality assessment tool.

Results

Out of 49 studies, only 14 systematic reviews respected the eligibility criteria and were included in this study. Their results showed an important heterogeneity of the studies and all of them agree on the lack of high-quality scientific work to prove unequivocally which rehabilitative treatment is better than the other. Due to this lack of gold standard criteria, there may be also a heterogeneity in the diagnosis of the reviews analyzed.

Conclusion

Non-surgical and rehabilitative interventions are undoubtedly effective in treating FS, but there is no evidence that one approach is more effective than the other regarding the methods reported. Future high-quality RCTs are needed to standardize the treatment modalities of each physiotherapy intervention to provide strong recommendations in favor.

Manipulation under Anesthesia versus Non-Surgical Treatment for Patients with Frozen Shoulder Contracture Syndrome: A Systematic Review

Purpose: To investigate the efficacy of manipulation under anesthesia (MUA) compared to other non-surgical therapeutic strategies for patients with frozen shoulder contracture syndrome (FSCS). Methods: A systematic review of literature was conducted. A literature search was performed in MEDLINE, EMBASE, PEDro, Cochrane Central Library and Scopus. Only randomized controlled trials were included and assessed for critical appraisal through the Cochrane Collaborations tools. Results: Five randomized controlled trials were included. The overall risk of bias (RoB) was high in 4 out of 5 of the included studies. MUA was found to be not superior in terms of reduction of pain and improvement of function when compared to cortisone injections with hydrodilatation (mean regression coefficient MUA −2.77 vs. injection −2.75; 95% CI (−1.11 to 1.15)) and home exercise (mean difference 95% CI: 0.2 (−0.64 to 1.02)) in the short term (3 months), and cortisone injections with hydrodilatation (mean regression coefficient MUA 3.13 vs. injection 3.23; 95% CI (−0.90 to 1.11)) in the long term (>6 months). Moreover, if compared to structured physiotherapy, MUA highlighted a higher Oxford Shoulder Score at final 1-year follow up (mean difference 95% CI: 1.05 (−1.28 to 3.39); p = 0.38). Similar results were obtained for disability, with statistically no significant long-term (>12 months) differences between MUA and home exercise (mean difference 95% CI: 0 (−3.2 to 3.2)) or structured physiotherapy (mean difference 95% CI: −0.50 (−5.70 to 4.70); p = 0.85)). Only two trials reported adverse events. Conclusions: This review suggested that limited and inconsistent evidence currently exists on the efficacy of MUA compared to other non-surgical strategies in the management of patients with FSCS. Future research should focus on clinical trials with higher methodological quality.

Post-surgical physiotherapy in frozen shoulder: A review

Despite its prevalence, the optimal management of frozen shoulder is unclear. A range of conservative measures are often undertaken with varying degrees of success. In cases of severe and persistent symptoms, release procedures which could include any combination of manipulation under anaesthetic, arthroscopic capsular release or hydrodilatation are frequently offered, none of which has been shown to offer superior outcome over the others. When surgical release is performed a period of rehabilitation is normally recommended but no best practice guidelines exist resulting in considerable variations in practice which may or may not directly affect patient outcome. During this narrative review, we hypothesise that these differing responses to treatment (both conservative and surgical options) are potentially the result of different causal mechanisms for frozen shoulder and may also suggest that post-release rehabilitation may need to take this into account.

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.

Living with a frozen shoulder - a phenomenological inquiry

BACKGROUND

Frozen shoulder (adhesive capsulitis) is an inflammatory condition affecting the capsule of the glenohumeral joint. It is characterised by a painful restricted range of passive and active movement in all planes of motion. The impact of frozen shoulder on affected individuals remains poorly characterised. In this study we sought to better understand the lived experience of people suffering from frozen shoulder to characterise the physical, psychological and socioeconomic impact of the condition.

METHODS

A qualitative study using a phenomenological approach was undertaken. Purposeful sampling was used to identify individuals for interview. Semi-structured interviews were performed and continued until saturation was achieved. A biopsychosocial framework was used during the analysis in order to generate themes which best described the phenomenon and reflected the lived experience of individuals' suffering from this condition.

RESULTS

Ten interviews were conducted, and five main themes emerged including; the severity of the pain experience, a loss of independence, an altered sense of self, the significant psychological impact, and the variable experience with healthcare providers.

CONCLUSIONS

These findings offer an insight into the lived experience of individuals with frozen shoulder, both on a personal and sociocultural level. The pain endured has profound impacts on physical and mental health, with loss of function resulting in a narrative reconstruction and altered sense of self. Our findings illustrate that frozen shoulder is much more than a benign self-limiting musculoskeletal condition and should be managed accordingly.

Anchoring Apparatus of Long Head of the Biceps Tendon: Ultrasonographic Anatomy and Pathologic Conditions

The long head of the biceps tendon (LHBT) has been recognized as an important generator of anterior shoulder pain, causing a significant reduction in the shoulder flexion range. Various tendinous and ligamentous structures form the anchoring apparatus of the LHBT along its course to maintain its appropriate location during shoulder movements, including the coracohumeral ligament (CHL), superior glenohumeral ligament (SGHL), subscapularis (SSC) tendon and supraspinatus (SSP) tendon as well as the less recognized tendons of pectoralis major (PM), latissimus dorsi (LD) and teres major (TM). Lesions of this stabilizing apparatus may lead to an instability of the LHBT, resulting in pain at the anterior shoulder. Ultrasonography (US) has been increasingly used in the assessment of shoulder injuries, including the anchoring apparatus of the LHBT. An accurate diagnosis of these injuries is often challenging, given the complex anatomy and wide spectrum of pathologies. In this review article, US anatomy and common pathologic conditions that affect the anchoring apparatus of the LHBT are discussed, including biceps pulley lesions, adhesive capsulitis, chronic pathology of SSC and SSP tendons, tears in the PM tendon and injuries to the LD and TM. Knowledge of a normal anatomy, an appropriate scanning technique and US findings of common pathologic conditions are the keys to accurate diagnoses.

Tender point examination with palpation in different shoulder pathologies: A retrospective study

BACKGROUND

Shoulder pain is a common symptom for non-traumatic shoulder pathologies and affects 4.7-66.7% of entire population. Even with the latest technological advantages, palpation still is a cost and time efficient tool to evaluate the shoulder pathologies. Our aim was to investigate and compare palpation findings in different shoulder pathologies.

METHOD

We used first assessments of impingement syndrome (IS) (n = 205), rotator cuff tear (RCT) (n = 185) and frozen shoulder (FS) (n = 210) patients who received treatment between 2010 and 2019 years. Two experienced physiotherapists palpated predefined points: long head of biceps brachii, pectoralis minor, lateral intermuscular septum, proximal tendons of extensor group. These points categorized into "proximal", "mid-proximal", "mid-distal", "distal", "irregular". We also grouped patients by their BMIs.

RESULTS

We found RCT patients had higher BMI than IS and FS patients (p < 0.001, p = 0.001); more tender intermuscular septum points and night pain than IS patients (p = 0.001, p = 0.003) and more extensor group proximal tendon points than IS and FS patients (p < 0.001, p = 0.001). "No tenderness" group had lesser resting pain than distal group (p < 0.001) and lesser activity and night pain than middle-proximal, middle-distal, and distal groups (all ps < 0.002). Distal group had higher night pain than middle-proximal group (p = 0.003). Morbidly obese patients had higher night pain than normal and overweight patients (p = 0.003 and p = 0.009).

CONCLUSIONS

Tender point distribution varies depending on the pathology with biceps brachii being the most common. RCT patients had higher night pain related to more distal tender points. Patients with higher night pain had increased tenderness in septum intermuscular and extensor muscles' proximal tendons.

A Central Nervous System Focused Treatment Program for People with Frozen Shoulder: A Feasibility Study

Background: Frozen shoulder (FS) is a highly disabling pathology of poorly understood etiology, which is characterized by the presence of intense pain and progressive loss of range of motion (ROM). The aim of this study is to evaluate the feasibility and clinical impact of a CNS-focused treatment program for people with FS. Methods: 10 subjects with primary FS received a 10-week CNS-focused intervention including sensory discrimination training and graded motor imagery techniques delivered as clinic sessions (60 min) and home therapy (30 min five times per week). Measurements were taken at baseline, after a 2-week “washout” period, after treatment, and at three months follow-up. The Shoulder Pain and Disability Index (SPADI) was the primary outcome. Secondary measures were feasibility-related outcomes, self-reported shoulder pain, active and passive range of motion, two-point discrimination threshold (TPDT), left/right judgement task (LRJT), fear-avoidance (Tampa Scale for Kinesiophobia), pain catastrophization (Pain Catastrophizing Scale), and pain sensitization (Central Sensitization Inventory). A Student’s t-test was used to assess the “washout” period. A repeated measure analysis of variance (ANOVA) was used to evaluate within-subjects’ differences for all outcome measures in the different assessment periods and a pairwise analysis was used to compare between the different assessment points. Statistical significance was set at p < 0.05. Results: 70% of participants completed the treatment. No significant changes were found after “washout” period except for TPDT (p = 0.02) and SPADI (p = 0.025). Improvements in self-reported shoulder pain (p = 0.028) and active shoulder flexion (p = 0.016) were shown after treatment (p = 0.028) and follow-up (p = 0.001) and in SPADI at follow-up (p = 0.008). No significant changes were observed in TPDT, LRJT, fear-avoidance, pain catastrophization, and pain sensitization. Conclusions: a CNS-focused treatment program might be a suitable approach to improve pain and disability in FS, but further research is needed to draw firm conclusions.

Frozen shoulder: living with uncertainty and being in "no-man's land"

BACKGROUND

Frozen Shoulder (FS) is a painful debilitating condition that is a significant burden to those experiencing it and healthcare systems. Despite research investigating the pathogenesis and effective treatment for the condition, there is a paucity of research exploring how having frozen shoulder is lived through and meaningful to persons experiencing it.

OBJECTIVE

To explore how living with Frozen Shoulder is experienced and meaningful.

METHODS

A qualitative research study design using hermeneutic phenomenology methodology was used. In-depth unstructured interviews were conducted with six purposively recruited participants. Interpretive Phenomenological methods were used to analyze the data forming emergent, superordinate and master themes to qualitatively expose the meaningful aspects of living through FS.

FINDINGS

Five Master themes were identified: 1) "Dropping me to my knees," an incredible pain experience; 2) The struggle for normality; 3) An emotional change of self; 4) The challenges of the healthcare journey; and 5) Coping and adapting. The overarching 'binding theme' was Frozen Shoulder: Living with uncertainty and being in "no-man's land."

CONCLUSIONS

This study illuminated the struggle to maintain a normal life while living with the significant pain, physical restriction, sleep loss and disability experienced by persons with Frozen Shoulder. Attempts to cope and adapt were impeded by the challenges of the healthcare journey. The uncertainty of these experiences was conveyed as being in "no man's land" an expression that reflected the existential crisis and impact on persons' sense of self.

Association between subscapularis trigger point and frozen shoulder: A cross sectional study

BACKGROUND

Frozen shoulder (FS) is one of the most common shoulder conditions characterized by pain, restricted range of motion and high morbidity. Though FS is known as adhesive capsulitis, presence of capsular adhesions has been rebutted and the nomenclature adhesive capsulitis is debated. It has been proposed that FS is a condition of cytokine driven capsular, ligamentous fibrosis and contracture. Despite extensive research on it, still it is unclear that how far the capsular contracture contribute to range of motion restriction in FS. Evidence also suggested that myofascial trigger points play a role in restricted range of motion.

OBJECTIVE

To find an association between subscapularis trigger point and frozen shoulder.

STUDY DESIGN

Cross-sectional study.

METHOD

143 Patients were screened for inclusion and exclusion criteria, out of which 100 patients, were selected for the study. Manual palpation was performed to look for subscapularis muscle trigger points via axillary approach on both the affected and unaffected side. Trigger point diagnosing criteria was used to diagnose subscapularis trigger points.

RESULTS

Results have shown that there was an association between subscapularis trigger point and frozen shoulder (X 2 = 32.151 P < 0.0001) on the affected side. We used Phi coefficient to measure the degree of association which denotes (Phi = 0.567 P < 0.0001) strong association between frozen shoulder and subscapularis trigger point on the affected side compared to unaffected side (X 2 9.157; P < 0.002: Phi:0.303: P < 0.002).

CONCLUSION

This study concluded that there appears to be a strong association between subscapularis trigger point and frozen shoulder.

Diabetes as a Prognostic Factor in Frozen Shoulder: A Systematic Review

•

People with diabetes may experience worse outcomes from frozen shoulder than those without diabetes; however, the certainty in evidence was moderate to low.

•

If high-quality studies can confirm the findings of this review, then clinicians should monitor patients with frozen shoulder with diabetes more closely and offer further treatment if pain or lack of function persists long-term.

Objective

To summarize evidence from longitudinal observational studies to determine whether diabetes (types 1 and 2) is associated with the course of symptoms in people with frozen shoulder.

Data Sources

A systematic literature search of 11 bibliographic databases (published through June 2021), reference screening, and emailing professional contacts.

Study Selection

Studies were selected if they had a longitudinal observational design that included people diagnosed with frozen shoulder at baseline and compared outcomes at follow-up (>2wk) among those with and without diabetes at baseline.

Data Extraction

Data extraction was completed by 1 reviewer using a predefined extraction sheet and was checked by another reviewer. Two reviewers independently judged risk of bias using the Quality in Prognostic Factor Studies tool.

Data Synthesis

A narrative synthesis, including inspection of forest plots and use of the prognostic factor Grading of Recommendations, Assessment, Development and Evaluations framework. Twenty-eight studies satisfied the inclusion criteria. Seven studies were judged to be at a moderate risk of bias and 21 at a high risk of bias. Diabetes was associated with worse multidimensional clinical scores (moderate certainty in evidence), worse pain (low certainty in evidence), and worse range of motion (very low certainty in evidence).

Conclusions

This review provides preliminary evidence to suggest that people with diabetes may experience worse outcomes from frozen shoulder than those without diabetes. If high-quality studies can confirm the findings of this review, then clinicians should monitor patients with frozen shoulder with diabetes more closely and offer further treatment if pain or lack of function persists long-term.

An overview of effective and potential new conservative interventions in patients with frozen shoulder

Frozen shoulder (FS) is a pathology that is difficult to understand and difficult to manage. Over the last ten years, contradictory and new evidence is provided regarding the recovery and its natural course. This narrative review provides new information about the diagnosis and conservative treatment of patients with FS and ongoing research hypotheses that might provide new insights in the pathology and treatment options. FS has a characteristic course. People with Diabetes Mellitus and thyroid disorders have a higher risk of developing a FS. The diagnosis FS is based on pattern recognition and physical examination. Additionally, 'rule-in' and 'rule-out' criteria can be used to increase the likelihood of the frozen shoulder diagnosis. Recommended and most common physical therapy interventions are mobilization techniques and exercises, in which tissue irritability can guide its intensity. In addition, physical therapy is often complementary with patient education and pharmacotherapy. The latest evidence-based practice related to FS is proprioceptive neuromuscular facilitation and mirror therapy. In addition, interventions like pain neuroscience education, high-intensity interval training and lifestyle changes are still hypothetical. Finally, better insight in the involvement of biochemical processes, function of myofibroblasts and matrix metalloproteinases can provide better understanding in the pathophysiology and will be addressed in current review.

Immediate Pain Relief at Time of Corticosteroid Injection for Idiopathic Adhesive Capsulitis as a Predictor of Eventual Outcomes

Background

Corticosteroid injection and physical therapy remain the mainstay of treatment for idiopathic adhesive capsulitis of the shoulder; however, a certain percentage of patients will not improve using these interventions and will require manipulation under anesthesia (MUA) and/or lysis of adhesions (LOA).

Purpose

To evaluate whether the immediate pain reduction after fluoroscopic-guided, mixed anesthetic-corticosteroid injection for idiopathic adhesive capsulitis is related to the eventual need for LOA/MUA or a repeat glenohumeral steroid injection.

Study Design

Case-control study; Level of evidence, 3.

Methods

This single-institution study involved patients undergoing fluoroscopic glenohumeral corticosteroid injection for a diagnosis of idiopathic adhesive capsulitis between 2010 and 2017. Included were patients with a minimum of 1-year postinjection follow-up and visual analog scale (VAS) pain scores from immediately before and after the injection. The primary analysis was the relationship between patients with an immediate change in VAS score after injection and those who underwent LOA/MUA. A repeat glenohumeral injection was also evaluated as an outcome. Receiver operator characteristic curves and a multivariate binomial logistic regression analysis were performed.

Results

Overall, 739 shoulders in 728 patients (mean age, 52.6 years; 68% women) were included, of which 38 (5.1%) underwent LOA/MUA and 209 (28%) underwent repeat injections. The immediate change in the VAS score was not significantly associated with the eventual need for LOA/MUA. Preinjection VAS and immediate postinjection VAS scores were not significant predictors of eventual LOA/MUA or subsequent injection. For all 3 predictors, the area under the receiver operator characteristic curve classified them as extremely poor discriminators.

Conclusion

The immediate pain response to a fluoroscopic-guided glenohumeral injection for idiopathic shoulder adhesive capsulitis was not predictive of the eventual need for LOA/MUA or subsequent injection. Patients can be counseled that even if their initial pain response to an injection is poor, they still have an excellent chance of avoiding surgery, as the overall rate of LOA/MUA was low (5.1%).

Efficacy of Arthroscopic Surgery in the Management of Adhesive Capsulitis: A Systematic Review and Network Meta-analysis of Randomized Controlled Trials

PURPOSE

To determine which interventions optimize clinical outcomes in adhesive capsulitis by performing a network meta-analysis of randomized controlled trials.

METHODS

A systematic review was conducted of all clinical trials on adhesive capsulitis published since 2008. Patient cohorts were grouped into treatment categories; data collected included range of motion (ROM) and patient-reported outcome measures (PROMs). Interventions were compared across groups by means of arm-based Bayesian network meta-analysis in a random-effects model.

RESULTS

Sixty-six studies comprising 4042 shoulders (57.6% female patients, age 54.8 ± 3.2 years [mean ± standard deviation]) were included. The most commonly studied interventions were physical therapy (PT) or shoulder injections. Network meta-analysis demonstrated that arthroscopic surgical capsular release was the most effective treatment in increasing ROM. This effect was apparent in forward flexion (effect difference [ED] versus placebo, 44°, 95% confidence interval [CI] 31° to 58°), abduction (ED 58°, 45° to 71°), internal rotation (ED 34°, 24° to 44°), and external rotation (ED 59°, 37° to 80°). Interventions most effective for pain relief included PT supplemented with either medical therapy (ED -4.50, -9.80 to 2.80) or ultrasound therapy (ED -5.10, -5.10 to -1.40). Interventions most effective for improvement of functional status included PT, manipulation under anesthesia (MUA), intra-articular or subacromial steroid injection, surgical capsular release, and supplementation of PT with alternative therapy.

CONCLUSIONS

No one treatment emerged superior in regard to ROM, pain symptoms, and functional status. Surgery (after failure of conservative treatment) ranked highest across all ROM domains. Treatments that ranked highest for treatment of pain included PT supplemented with either medical therapy or ultrasound. Finally, treatments that ranked highest for improvements in functional status included MUA, PT with medical therapy, surgical intervention, PT with ultrasound, PT with injection, and injection alone.

LEVEL OF EVIDENCE

II, systematic review and network meta-analysis of level I and II studies.

The Efficacy and Treatment Fidelity of Kinesiology Taping in Conjunction With Conservative Treatment Interventions Among Individuals With Shoulder Pain: A Systematic Review with Meta-Analysis

PURPOSE

Kinesiology taping is a common intervention used to treat individuals with shoulder pain. While there have been several studies published to date evaluating the effectiveness of this intervention, a systematic review with meta-analysis synthesizing the collective effectiveness of kinesiology taping is not available. Therefore, the purpose of this study was to perform a systematic review with meta-analysis investigating the efficacy and treatment fidelity of kinesiology taping (KT) in combination with conservative interventions for shoulder pain.

METHODS

Databases (PubMed, EMBASE, SportDiscus, CINAHL) of studies published in English meeting criteria were searched to October 2019. Methodologic quality was assessed utilizing the Modified Downs and Black checklist. Treatment fidelity was evaluated using a modified fidelity tool. Random effects meta-analyses were performed when an outcome (disability, pain, range of motion (ROM)) was reported by two or more studies. Overall effect size (pooled random effects) was estimated for studies with acceptable clinical homogeneity.

RESULTS

When KT was used with conservative treatments, meta-analysis revealed large effect sizes for improvements in disability (standard mean difference (SMD) = -1.35; 95% CI, -2.09 to -0.60) and ROM (SMD = 0.96; 95% CI, 0.60-1.33) with no significant effects for pain. The average Modified Downs & Black score for bias was 11.5 ± 3.9. Of 10 retained studies, only two had good treatment fidelity.

CONCLUSIONS

Adding KT to interventions performed in clinical settings appears to demonstrate efficacy regarding disability and ROM when compared to conservative interventions alone. However, despite reasonably good methodologic quality, fidelity was lacking in a majority of studies. Because of its impact on the implementation of evidence-based practice, lower fidelity should be considered when interpreting results.

Comparison of efficacy and safety of complementary and alternative therapies for scapulohumeral periarthritis: A protocol for Bayesian network meta-analysis

BACKGROUND

Scapulohumeral periarthritis is a disease with high incidence and great pain. The current western treatments with many side effects, poor efficacy cannot fundamentally solve the problem. Complementary and alternative therapies have played an excellent role in the treatment of scapulohumeral periarthritis. However, it is not clear which complementary and alternative therapy is more effective. Therefore, we propose a protocol to compare the efficacy and safety of various complementary and alternative therapies through network meta-analysis (NMA) to provide choice guidance for the therapy.

METHODS

A comprehensive search will be conducted for randomized controlled trials of complementary and alternative therapy for scapulohumeral periarthritis as well as ongoing trials. The time limit is from the establishment of the database until January 2021. Literature and data extraction were completed independently by two researchers. Through pairwise comparison and meta-analysis of Bayesian NMA, all the evidences are evaluated comprehensively. STATA16.0 and WinBUGS1.4.3 software will be used for data processing and analysis, and recommendation evaluation will be used to develop and assess grades to classify the quality of NMA evidence.

RESULTS

Through the analysis, we will obtain the ranking of the efficacy and safety of different complementary and alternative therapies in the treatment of scapulohumeral periarthritis, in order to provide reference for clinical selection of treatment methods.

CONCLUSION

Complementary and alternative therapies of scapulohumeral periarthritis plays a positive role in improving the symptoms of scapulohumeral periarthritis. This study can provide evidence support for clinicians and patients.International Platform of Registered Systematic Review and Meta-Analysis Protocols registration number: INPLASY202140044.

Updates on the treatment of adhesive capsulitis with hydraulic distension

Adhesive capsulitis of the shoulder joint is a common disease characterized by pain at the insertional area of the deltoid muscle and decreased range of motion. The pathophysiological process involves fibrous inflammation of the capsule and intraarticular adhesion of synovial folds leading to capsular thickening and contracture. Regarding the multidirectional limitation of motion, a limitation in external rotation is especially prominent, which is related to not only global fibrosis but also to a localized tightness of the anterior capsule. Ultrasound and magnetic resonance imaging studies can be applied to rule out other structural lesions in the diagnosis of adhesive capsulitis. Hydraulic distension of the shoulder joint capsule provides pain relief and an immediate improvement in range of motion by directly expanding the capsule along with the infusion of steroids. However, the optimal technique for hydraulic distension is still a matter of controversy, with regards to the infusion volume and rupture of the capsule. By monitoring the real-time pressure-volume profile during hydraulic distension, the largest possible fluid volume can be infused without rupturing the capsule. The improvement in clinical outcomes is shown to be greater in capsule-preserved hydraulic distension than in capsule-ruptured distension. Moreover, repeated distension is possible, which provides additional clinical improvement. Capsule-preserved hydraulic distension with maximal volume is suggested to be an efficacious treatment option for persistent adhesive capsulitis.

Pain-related beliefs are associated with arm function in persons with frozen shoulder

BACKGROUND

Frozen shoulder is a painful glenohumeral joint condition. Pain-related beliefs are recognized drivers of function in musculoskeletal conditions. This cross-sectional study investigates associations between pain-related beliefs and arm function in frozen shoulder.

METHODS

Pain intensity, arm function (Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH)), pain catastrophizing (Pain Catastrophizing Scale (PCS)), pain-related fear (Tampa Scale for Kinesiophobia (TSK-11)) and pain self-efficacy (Pain Self-Efficacy Questionnaire (PSEQ)) were administered in 85 persons with frozen shoulder. Correlation analyses assessed associations between pain-related beliefs and arm function. Regression analysis calculated the explained variance in arm function by pain-related beliefs.

RESULTS

Pain-related fear, pain catastrophizing and pain self-efficacy were significantly associated with arm function (r = 0.51; r = 0.45 and r = -0.69, all p < .0001, respectively). Thirty-one percent of variance in arm function was explained by control variables, with pain intensity being the only significant one. After adding TSK-11, PCS and PSEQ scores to the model, 26% extra variance in arm function was explained, with significant contributions of pain intensity, pain-related fear and pain self-efficacy (R²= 0.57).

CONCLUSIONS

Attention should be paid towards the negative effect of pain-related fear on outcomes in frozen shoulder and towards building one's pain self-efficacy given its protective value in pain management.

Are clinical outcomes of frozen shoulder linked to pain, structural factors or pain-related cognitions? An explorative cohort study

BACKGROUND

In frozen shoulder (FS), inflammatory-fibrotic adaptations in capsuloligamentous structures are typically linked to perceived glenohumeral stiffness, glenohumeral range of motion (ROM) restrictions and decreased arm function. However, ROM restrictions based on muscle guarding are suggested as well.

OBJECTIVES

To assess differences between pain, perceived stiffness, ROM restrictions and arm function at time of diagnosis and at four months follow-up and to assess whether perceived stiffness, ROM restrictions and arm function relate to pain, structural and/or cognitive factors.

DESIGN

observational cohort study.

METHODS

In persons with idiopathic FS, pain intensity at rest/at night/during activities (Numeric Rating Scale), perceived stiffness (Numeric Rating Scale), abduction/external rotation ROM (goniometry), and function (Disabilities of the Arm, Shoulder and Hand Questionnaire) were compared between both time points (Wilcoxon-signed rank tests). Spearman correlation coefficients assessed the relation between perceived stiffness, ROM and function on the one hand and structural factors (coracohumeral ligament (CHL) thickness and inferior glenohumeral recess (IGR) perimeter - arthroMRI), pain intensity and pain-related cognitions (Pain Catastrophizing Scale, Tampa Scale for Kinesiophobia) on the other hand.

RESULTS

Twenty persons participated (14 female; 56±8yrs) and three persons dropped out at 4 months. Pain intensity, perceived stiffness, ROM and arm function improved over time. ROM was related to CHL-thickness and IGR-perimeter; perceived stiffness was related to pain intensity; and arm function was related to pain intensity and pain-related cognitions.

CONCLUSION

Objectively measured ROM is related to structural factors, while patient-reported outcomes are related to pain intensity and/or pain-related cognitions. Perceived stiffness does not relate to structural factors.

Intra-articular distension preceded by physical therapy versus intra-articular distension followed by physical therapy for treating adhesive capsulitis of the shoulder

BACKGROUND

Intra-articular distension is a validated treatment in adhesive capsulitis of the shoulder and is commonly followed by intensive in-patient physical therapy. A recent meta-analysis found that physical therapy is as effective as intra-articular distension (IAD) and that an early distension could be the primary choice for treating frozen shoulder. The question of the additional contribution of physical therapy prior to IAD compared with IAD followed by physical therapy has not been raised.

OBJECTIVES

We compared IAD preceded by physical therapy to that followed by physical therapy in terms of pain relief and functional outcome.

METHODS

We enrolled patients with primitive adhesive capsulitis of the shoulder. The eligible patients were randomized into three groups: A, B and C. Group A received intra-articular distension followed by physical therapy, group B received intra-articular distension in the middle of physical therapy and group C received physical therapy alone. Patients were assessed at the beginning of the protocol (T0), after 6 weeks (T1) and after 12 weeks (T2). The main outcome measures were pain using a Visual Analog Scale and the Disabilities of Arm, Shoulder and Hand Questionnaire.

RESULTS

Out of the 179 enrolled patients, only 122 completed the follow up: group A (n= 34), group B (n= 46) and group C (n= 42). Compared to intra-articular distension preceded by physical therapy, IAD followed by physical therapy did not improve significantly the outcome in terms of pain relief (p= 0.123) but it enhanced the upper extremity function (p= 0.002). Upper extremity pain and function were found to improve with time regardless of the protocol (p< 0.001).

CONCLUSIONS

IAD followed by physical therapy is more beneficial than IAD preceded by physical therapy in terms of upper extremity function. IAD, whether or not preceded by physical therapy, does not significantly improve pain compared to physical therapy alone. Time is a crucial factor to take into consideration while treating adhesive capsulitis of the shoulder.

Motor Imagery Performance and Tactile Spatial Acuity: Are They Altered in People with Frozen Shoulder?

Frozen shoulder (adhesive capsulitis) is a severe chronic pain condition that is not well understood and current treatment is suboptimal. In several other chronic pain conditions motor imagery and tactile acuity deficits are present, which are thought to represent associated neuroplastic changes. The aims of this study were to determine if motor imagery performance assessed by the left/right judgement task, and tactile acuity assessed by two-point discrimination, are altered in people with unilateral frozen shoulder. In this cross-sectional, prospective study eighteen adults diagnosed with frozen shoulder in a physiotherapy clinic setting completed a left/right judgement task, response times (RT) and accuracy for the left/right judgement task were determined. Next, tactile acuity over both shoulders was assessed with a novel, force-standardised two-point discrimination test. Results corresponding to the affected side were compared to the pain free shoulder; Left/right judgement task: mean RT (SD) corresponding to the affected shoulder was significantly slower than RT for the healthy shoulder (p = 0.031). There was no side-to-side difference in accuracy (p > 0.05). Neither RT nor accuracy was related to pain/disability scores or duration of symptoms (p > 0.05). Two-point discrimination: mean two-point discrimination threshold of the affected shoulder was significantly larger than the contralateral healthy shoulder (p < 0.001). Two-point discrimination threshold was not related to pain/disability scores or pain duration (p > 0.05); One explanation for these findings is altered sensorimotor processing and/or disrupted sensorimotor cortex representations of the affected shoulder. A case then exists for the use of treatments aimed at reversing these changes, training the brain to reduce chronic shoulder pain.

'Frozen shoulder' is ill-defined. How can it be described better?

Frozen shoulder, a common and debilitating shoulder complaint, has been the subject of uncertainty within the scientific literature and clinical practice.

We performed an electronic PubMed search on all (1559) articles mentioning ‘frozen shoulder’ or ‘adhesive capsulitis’ to understand and qualify the range of naming, classification and natural history of the disease. We identified and reviewed six key thought leadership papers published in the past 10 years and all (24) systematic reviews published on frozen shoulder or adhesive capsulitis in the past five years.

This revealed that, while key thought leaders such as the ISAKOS Upper Extremity Council are unequivocal that ‘adhesive capsulitis’ is an inappropriate term, the long-term and short-term trends showed the literature (63% of systematic reviews assessed) preferred ‘adhesive capsulitis’.

The literature was divided as to whether or not to classify the complaint as primary only (9 of 24) or primary and secondary (9 of 24); six did not touch on classification.

Furthermore, despite a systematic review in 2016 showing no evidence to support a three-phase self-limiting progression of frozen shoulder, 11 of 12 (92%) systematic reviews that mentioned phasing described a three-phase progression. Eight (33%) described it as ‘self-limiting’, three (13%) described it as self-limiting in ‘nearly all’ or ‘most’ cases, and six (25%) stated that it was not self-limiting; seven (29%) did not touch on disease resolution.

We call for a data and patient-oriented approach to the classification and description of the natural history of the disease, and recommend authors and clinicians (1) use the term ‘frozen shoulder’ over ‘adhesive capsulitis’, (2) use an updated definition of the disease which recognizes the often severe pain suffered, and (3) avoid the confusing and potentially harmful repetition of the natural history of the disease as a three-phase, self-limiting condition.

Common Musculoskeletal Disorders in the Elderly: The Star Triad

Musculoskeletal disorders are debilitating conditions that significantly impair the state of health, especially in elderly subjects. A pathological triad of inter-related disorders that are highly prevalent in the elderly consists of the following main “components”: sarcopenia, tendinopathies, and arthritis. The aim of this review is to critically appraise the literature relative to the different disorders of this triad, in order to highlight the pathophysiological common denominator and propose strategies for personalized clinical management of patients presenting with this combination of musculoskeletal disorders. Their pathophysiological common denominator is represented by progressive loss of (focal or generalized) neuromuscular performance with a risk of adverse outcomes such as pain, mobility disorders, increased risk of falls and fractures, and impaired ability or disability to perform activities of daily living. The precise management of these disorders requires not only the use of available tools and recently proposed operational definitions, but also the development of new tools and approaches for prediction, diagnosis, monitoring, and prognosis of the three disorders and their combination.

An investigation of perceptual biases in complex regional pain syndrome

Patients with complex regional pain syndrome (CRPS) report cognitive difficulties, affecting the ability to represent, perceive and use their affected limb. Moseley, Gallace & Spence (2009) observed that CRPS patients tend to bias the perception of tactile stimulation away from the pathological limb. Interestingly, this bias was reversed when CRPS patients were asked to cross their arms, implying that this bias is embedded in a complex representation of the body that takes into account the position of body-parts. Other studies have failed to replicate this finding (Filbrich et al., 2017) or have even found a bias in the opposite direction (Sumitani et al., 2007). Moreover, perceptual biases in CRPS patients have not often been compared to these of other chronic pain patients. Chronic pain patients are often characterized by an excessive focus of attention for bodily sensations. We might therefore expect that non-CRPS pain patients would show a bias towards instead of away from their affected limb. The aim of this study was to replicate the study of Moseley, Gallace & Spence (2009) and to extend it by comparing perceptual biases in a CRPS group with two non-CRPS pain control groups (i.e., chronic unilateral wrist and shoulder pain patients). In a temporal order judgment (TOJ) task, participants reported which of two tactile stimuli, one applied to either hand at various intervals, was perceived as occurring first. TOJs were made, either with the arms in a normal (uncrossed) position, or with the arms crossed over the body midline. We found no consistent perceptual biases in either of the patient groups and in either of the conditions (crossed/uncrossed). Individual differences were large and might, at least partly, be explained by other variables, such as pain duration and temperature differences between the pathological and non-pathological hand. Additional studies need to take these variables into account by, for example, comparing biases in CRPS (and non-CRPS) patients in an acute versus a chronic pain state.

The effectiveness of hydrodistension and physiotherapy following previously failed conservative management of frozen shoulder in a UK primary care centre

BACKGROUND

There is a lack of evidence on the clinical effectiveness of hydrodistension for frozen shoulder following failed conservative management.

METHODS

A total of 90 patients opted for hydrodistension following failed initial treatment which included physiotherapy and at least one corticosteroid injection. Shoulder pain and function were assessed at baseline, and 6, 12 and 24 weeks using the Shoulder Pain Disability Index (SPADI), The Upper Extremity Functional Index (UEFI) and a visual analogue scale (VAS) for pain. Active ranges of motion were assessed at baseline, post-24 hr and discharge.

RESULTS

We observed clinically important improvements in pain (VAS -5.5; 90% confidence interval [CI] -6.0 to -5.0; SPADI pain, -20; 90% CI-23 to -17) and function (UEFI 23; 90% CI 19 to 26; SPADI disability, -32; 90% CI -36 to -28) at 6 weeks. These improvements remained clearly substantial at 24 weeks. Active range of motion improved substantially post-24 hr (flexion 20, 90% CI 18 to 23; lateral rotation 14, 90% CI 12 to 16; abduction 22, 90% CI 19 to 25) and at discharge (flexion 37, 90% CI 33 to 41; lateral rotation 24, 90% CI 21 to 27; abduction 44, 90% CI 38 to 50).

DISCUSSION

This single-arm observational study suggests that hydrodistension is an effective treatment of frozen shoulder within a UK primary care setting when standard treatment has failed.
