Fostering Adherence to Evidence-Based Care in the Management of Musculoskeletal Shoulder Pain: A Mixed-Methods Study

OBJECTIVE

The objective was to identify the priorities of individuals with musculoskeletal shoulder pain and their health care providers (HCPs) that are perceived to foster multistakeholder adherence to evidence-based recommendations.

METHODS

The study used a mixed-methods design, informed by concept mapping. Patients with shoulder pain (ie, ≥6 weeks) and HCPs involved in their care (recruited via social media, email, etc) were invited to complete an initial survey to identify perceived priorities to foster adherence to evidence-based recommendations. Preliminary data sorting resulted in a final priority list, with a subset (n = 20) of respondents rating their importance using a Likert scale. A public and patient involvement (PPI) panel (N = 8) assisted in this rating phase, further sorting of priorities based on thematic similarities (ie, into categories and then domains), analysis, interpretation, and developing a concept map illustrating relationships between them.

RESULTS

One hundred and fifty-four participants (HCPs = 133; patients = 21) responded to the initial survey, generating 77 priorities, grouped into 13 categories, and then into 3 domains: (1) Education, (2) Patient-centered care, and (3) Health care communication. Patients prioritized categories relating to the provision of a specific diagnosis, the establishment of a strong therapeutic relationship, and the need for education on progress and recovery timelines, as well as treatment options. HCPs prioritized these same educational categories, also prioritizing the need for tailoring exercise therapy and providing a unified message on best management. PPI panelists identified education on treatment options coupled with a strong therapeutic alliance and a unified message on best management to be of pivotal importance in fostering adherence. Panelists also stressed that future knowledge translation resources must provide tailored education.

CONCLUSION

HCPs and patients agree on the need to prioritize education related to progress and recovery timelines as well as treatment options, with a strong therapeutic alliance and a unified message on best management also considered of pivotal importance for adherence to evidence-based recommendations.

IMPACT

To the knowledge of the authors, this is the first study, including a broad range of stakeholder groups spanning across 11 different countries, to explore the priorities that stakeholders perceived to support stricter adherence to evidence-based recommendations for musculoskeletal shoulder pain, with the relationship between these priorities visually illustrated using a concept map. Patients and HCPs were united in their prioritization of education relating to expected progress and recovery timelines, as well as treatment options and supporting evidence. Stakeholders also identified the need for greater emphasis to be placed on establishing a therapeutic relationship and on integrating shared decision-making into clinical practice to further facilitate adherence. Education relating to treatment options and supporting evidence, a strong therapeutic relationship, and a unified message on best management were perceived by the PPI panel as being pivotal in facilitating adherence to evidence-based treatment. The findings of this study highlight the need for improved tailoring of educational resources for shoulder pain, as well as more cohesive messaging from health care providers, both assisting in supporting first-line treatments, such as exercise therapy, for musculoskeletal shoulder pain.

Patterns of Imaging Requests By General Practitioners for People With Musculoskeletal Complaints: An Analysis From a Primary Care Database

OBJECTIVE

The aim of this study was to examine imaging requested by general practitioners (GPs) for patients with low back, neck, shoulder, and knee complaints over 5 years (2014-2018).

METHODS

This analysis from the Australian Population Level Analysis and Reporting database included patients presenting with a diagnosis of low back, neck, shoulder, and/or knee complaints. Eligible imaging requests included low back and neck x-ray, computed tomography (CT), and magnetic resonance imaging (MRI); knee x-ray, CT, MRI, and ultrasound; and shoulder x-ray, MRI, and ultrasound. We determined number of imaging requests and examined their timing, associated factors, and trends over time. Primary analysis included imaging requests from 2 weeks before diagnosis to 1 year after diagnosis.

RESULTS

There were 133,279 patients (57% low back, 25% knee, 20% shoulder, and 11% neck complaints). Imaging was most common among those with a shoulder (49%) complaint, followed by knee (43%), neck (34%), and low back complaints (26%). Most requests occurred simultaneously with the diagnosis. Imaging modality varied by body region and, to a lesser extent, by gender, socioeconomic status, and primary health network. For low back, there was a 1.3% (95% confidence interval [95% CI] 1.0-1.6) annual increase in proportion of MRI and a concomitant 1.3% (95% CI 0.8-1.8) decrease in CT requests. For neck, there was a 3.0% (95% CI 2.1-3.9) annual increase in proportion of MRI and a concomitant 3.1% (95% CI 2.2-4.0) decrease in x-ray requests.

CONCLUSION

GPs commonly request early diagnostic imaging for musculoskeletal complaints at odds with recommended practice. We observed a trend towards more complex imaging for neck and back complaints.

Shoulder Musculoskeletal Disorder Rehabilitation Using a Robotic Device Based on Electromyography (EMG) Biofeedback: A Retrospective Cohort Study

Background and Objectives: While shoulder injuries represent the musculoskeletal disorders (MSDs) most encountered in physical therapy, there is no consensus on their management. In attempts to provide standardized and personalized treatment, a robotic-assisted device combined with EMG biofeedback specifically dedicated to shoulder MSDs was developed. This study aimed to determine the efficacy of an 8-week rehabilitation program (3 sessions a week) using a robotic-assisted device combined with EMG biofeedback (RA-EMG group) in comparison with a conventional program (CONV group) in patients presenting with shoulder MSDs. Materials and Methods: This study is a retrospective cohort study including data from 2010 to 2013 on patients initially involved in a physical rehabilitation program in a private clinic in Chicoutimi (Canada) for shoulder MSDs. Shoulder flexion strength and range of motion were collected before and after the rehabilitation program. Forty-four patients participated in a conventional program using dumbbells (CONV group), while 73 completed a program on a robot-assisted device with EMG and visual biofeedback (RA-EMG group); both programs consisted of two sets of 20 repetitions at 60% of maximal capacity. Results: We showed that the RA-EMG had significantly greater benefits than the CONV group for shoulder flexion strength (4.45 [2.6;6.15] kg vs. 2.3 [0.90;4.775] kg, U = 761, p = 0.013) and for normalized strength (77.5 [51.3;119.1] % vs. 39.1 [16.6;89.2] %, U = 755, p = 0.016). In addition, the RA-EMG group showed a trend to greater absolute gain of ROM than the CONV group (10.0 [0;24.3] degrees vs. 5.5 [0;12.0] degrees, U = 1931, p = 0.067), and a greater benefit in normalized ROM was observed for the RA-EMG (7.4. [0;17.7] %) than the CONV group (4.6 [0;10.8], U = 1907, p = 0.046). Conclusions: The current retrospective cohort study showed that a specific and tailored 8-week rehabilitation program with constant effort by automatic adjustment of the level of resistance by EMG feedback induced greater benefits for shoulder flexion strength and a trend to improve range of motion compared to conventional rehabilitation in patients with shoulder MSDs. Future research should be pursued to determine the added potential of this approach for abduction and external rotation with a randomized controlled design.

Theory-Informed Development of a Multicomponent Intervention to Implement Clinical Practice Guideline Recommendations in the Management of Shoulder Pain

OBJECTIVE

Suboptimal primary health care management of shoulder pain has been reported in previous studies. Implementing clinical practice guidelines (CPGs) recommendations using a theoretical approach is recommended to improve shoulder pain management. This study aims to identify determinants of implementing recommendations from shoulder CPGs to help develop an intervention based on the identified determinants.

METHODS

Family physicians and physical therapists managing patients with shoulder pain in primary care were invited to participate in a qualitative study to identify determinants to implementing recommendations from shoulder CPGs. The Theoretical Domains Framework (TDF) was used to inform the creation of the semi-structured interview guide and for deductive coding of transcriptions. The determinants were mapped to intervention functions and behavior change techniques (BCT) using the Behavior Change Wheel method and strategies for implementing CPGs recommendations were identified.

RESULTS

Interviews were conducted with 16 family physicians and 19 physical therapists. We identified 12 barriers and 6 facilitators within 7 TDF domains: knowledge, skills, beliefs about capabilities, beliefs about consequences, intentions, environmental context and resources, and social influence. We identified 6 intervention functions and 12 BCT addressing the relevant determinants. The 11 implementation strategies identified include the development and distribution of educational material, interactive educational outreach visits, and audit and feedback. Other components to consider are the identification and preparation of champions in primary care clinical settings, revision of professional roles, and creation of interdisciplinary clinical teams.

CONCLUSIONS

The identification of barriers and facilitators to implementing recommendations from shoulder CPGs allowed us to select implementation strategies at individual and organizational levels.

IMPACT

The implementation strategies will be adapted to specific primary care contexts in consultation with stakeholders and operationalized into a multicomponent implementation intervention. Implementing the intervention has the potential to improve shoulder pain management in primary care and facilitate the use of evidence-based recommendations from CPGs.

Preoperative corticosteroid injections are associated with a higher periprosthetic infection rate following primary total shoulder arthroplasty: a systematic review and meta-analysis

BACKGROUND

Corticosteroid injections (CSIs) are commonly used for the treatment of shoulder pain in patients with osteoarthritis and rotator cuff arthropathy. These injections may increase the risk of infection following eventual shoulder arthroplasty. The purpose of this study was to perform a systematic review and meta-analysis of existing data to explore the relationship between preoperative CSI's and postoperative periprosthetic joint infection (PJI) following shoulder arthroplasty.

METHODS

A literature search was performed on PubMed, Embase, and Web of Science databases through September 29, 2023. Of the 4221 retrieved, 7 studies including 136,233 patients were included for qualitative analysis. Studies describing patients receiving CSI prior to shoulder arthroplasty and the effect on postoperative infection risk were included in the systematic review and subsequent meta-analysis. Assessment of risk of bias was performed using the Methodological Index for Non-Randomized Studies (MINORS) criteria.

RESULTS

Receiving a CSI prior to shoulder arthroplasty was found to have a statistically significant association with increased risk for PJI (odds ratio [OR]: 1.13; 95% confidence interval [CI]: 1.06-1.19; P < .0001). The rate of PJI increased when injections were given closer to the time of surgery. Patients who received an injection at any time point before surgery had a 5.4% risk of PJI compared to 7.9% and 9.0% in patients receiving an injection within 3 months and 1 month of surgery, respectively. This time dependent association however did not reach statistical significance: 1 month OR 1.48; 95% Cl: 0.86-2.53; P = .16, 3 months OR 1.95; 95% Cl: 0.95-4.00; P = .07.

CONCLUSION

The results of this systematic review and meta-analysis demonstrate that patients receiving corticosteroid shoulder injections prior to shoulder arthroplasty may be at an increased risk for PJI postoperatively. While time dependent stratification did not reach statistical significance, our findings indicate a clear trend of increased risk for patients receiving injections closer to surgery.

Patient experiences of rotator cuff-related shoulder pain and their views on diagnostic shoulder imaging: a qualitative study

PURPOSE

To explore patient experiences of rotator cuff-related shoulder pain, and their views on the role and value of diagnostic shoulder imaging.

MATERIALS AND METHODS

Semi-structured interviews were conducted with 20 patients with shoulder pain exploring the impact and management of their shoulder condition, reasons for and experiences of diagnostic imaging, and feelings about and responses to diagnostic imaging findings. Framework analysis was used to analyse the dataset.

RESULTS

Five themes were identified [1]: Lived experience and beliefs about pain and movement [2]; Contextualisation of imaging findings by health professionals is more important than the imaging report [3]; Factors influencing whether and when to have imaging [4]; Imaging can identify the actual problem and guide treatment; and [5] Treatment responses and treatment decision making.

CONCLUSION

Patients commonly believe imaging is needed to formulate a diagnosis. There was minimal concern about potential indirect harms that could arise (e.g., inappropriate diagnosis leading to unnecessary treatments). The context of the diagnostic imaging reports (i.e., what needed to be done) was perceived as more important than the exact meaning of the imaging findings. Patients felt that the diagnostic imaging confirmed their existing biomedical beliefs, and these beliefs were not challenged by their healthcare professionals.

An Analysis of the Structures People With Shoulder Pain Recall After Receiving Their Diagnostic Imaging Results

AIMS

Rotator cuff related shoulder pain (RCRSP) is a prevalent cause of musculoskeletal pain. Patients presenting with this condition often undergo diagnostic imaging. However, many patients appear to have difficulty recalling the nature of their diagnosis. This may impact their rehabilitation outcomes. The aim of this study was to explore peoples' recall of their structural features relating to RCRSP by comparing their recalled description of their condition with the contents of their imaging reports as reported in an online questionnaire. In doing so, we aim to explore the potential emphasis they place on structural features related to their condition.

METHODS

This study was a content analysis embedded within a larger survey study published previously. Data containing patients' recall of their diagnosis was used from the study, and analysed using content analysis to quantify content in terms of codes and categories. The aims of frequency, completeness and accuracy of recall were then explored.

RESULTS

The analysis identified eight categories of terminology either recalled by patients or reported in imaging reports. The most frequent categories in reports were tendinopathy (71%) and joint (67%), but only 17% and 36% of participant responses contained these codes, respectively. Participants' completeness of recall compared with their imaging report was 30% on average. In terms of accuracy, only 8 out of 95 participants recalled their diagnoses 100% correctly.

CONCLUSION

This study indicates that patients have poor overall recall of their RCRSP-related structural features. We contend that participants may have been able to recall what they viewed to be the most prominent structural feature in their imaging findings. It may be important for clinicians to consider the impact of diagnostic labelling, and whether a patient's ability to recall such labelling may have an influence on their outcomes.

Influence of Frequent Corticosteroid Local Injections on the Expression of Genes and Proteins Related to Fatty Infiltration, Muscle Atrophy, Inflammation, and Fibrosis in Patients With Chronic Rotator Cuff Tears: A Pilot Study

Background

The effect of local corticosteroid (CS) injections on rotator cuff muscles remains poorly defined, despite the significance of muscle quality as a crucial prognostic factor for patients with rotator cuff tears (RCTs).

Purpose

To compare alterations in gene and protein expression patterns in the rotator cuff muscles of patients with RCTs who received frequent joint CS injections with alterations in those without a history of CS injections.

Study Design

Controlled laboratory study.

Methods

A total of 24 rotator cuff muscle samples with medium-sized tears from 12 patients with a frequent joint CS injection history (steroid group; 7 men and 5 women who had received ≥5 injections with at least 1 within the previous 3 months; mean age, 63.0 ± 7.2 years) and 12 age- and sex-matched control patients without a history of CS injections (no-steroid group) were acquired. Alterations in the expression of genes and proteins associated with adipogenesis, myogenesis, inflammation, and muscle fibrosis were compared between the groups using quantitative reverse transcription-polymerase chain reaction, Western blotting, and immunohistochemistry. Statistical analysis included comparison of group means using the Mann-Whitney U test, chi-square test, or Fisher exact test and logistic regression for multivariate analysis.

Results

In the steroid group, the mRNA expression levels of adipogenic CCAAT/enhancer-binding protein alpha (C/EBPα; P = .008) and muscle atrophy-related genes (atrogin; P = .019) were significantly higher, and those of myogenic differentiation 1 (MyoD; P = .035), inflammatory interleukin 6 (IL-6; P = .035), and high mobility group box 1 (P = .003) were significantly lower compared with the no-steroid group. In addition, MyoD (P = .041) and IL-6 (P = .026) expression were decreased in the steroid versus no-steroid group. Immunohistochemistry revealed increased expression of C/EBPα and atrogin and decreased expression of MyoD and IL-6 in the steroid versus no-steroid group.

Conclusion

Patients with RCTs and a history of frequent CS injections exhibited an upregulation of adipogenic and muscle atrophy-related genes and proteins within the rotator cuff muscles and a downregulation in the expression of myogenic and inflammatory genes and proteins in the same muscles.

Clinical Relevance

These altered gene and protein expressions by frequent local CS injections may cause poor outcomes in patients with RCTs.

Ultrasound Versus Magnetic Resonance Imaging as First-Line Imaging Strategies for Rotator Cuff Pathologies: A Comprehensive Analysis of Clinical Practices, Economic Efficiency, and Future Perspectives

Rotator cuff injuries are a prevalent cause of atraumatic chronic shoulder pain, imposing a significant healthcare burden. This article reviews the clinical presentation, diagnostic imaging modalities, practice variations, and economic efficiency considerations in the evaluation of rotator cuff pathologies. Ultrasound (US) and magnetic resonance imaging (MRI) are the primary imaging methods for diagnosing rotator cuff injuries. US provides real-time visualization but has limited tissue penetration, while MRI offers detailed anatomical information but is not a dynamic process. Studies show that MRI is superior to US with higher sensitivity and specificity. MRI is the gold standard, particularly for surgical planning, but US remains relevant when MRI is not feasible. Both require standardized protocols for evaluating tear dimensions and muscle atrophy. With the operator-dependent nature of US, MRI offers a more comprehensive assessment of rotator cuff tears and predictive insights for clinical outcomes. Practice variations exist in the management of rotator cuff pathologies, with some countries favoring US as the primary imaging modality and others relying more on MRI. These variations are influenced by factors like resource availability and healthcare system nuances. In Australia, current guidelines lean toward conservative management, potentially leading to delayed diagnoses and increased costs. The United States often favors MRI, while Canada advocates for US as the initial choice. Economic considerations play a significant role in selecting imaging modalities. While US is cost-effective, it may necessitate subsequent MRI examinations, contributing to inefficiencies in the diagnostic process. Studies suggest that a combined approach of US and MRI is less efficient and cost-effective than MRI alone. However, the use of both modalities rather than MRI alone is common in clinical practice, adding to healthcare expenses. In conclusion, the choice of imaging modality for rotator cuff pathologies should consider factors such as diagnostic efficacy, cost-effectiveness, and resource availability. Radiologists play a pivotal role in guiding this selection and ensuring comprehensive evaluations. Future considerations should include the revision of management guidelines and the potential inclusion of shoulder pathologies in healthcare coverage to optimize patient care and healthcare expenditure.

Education can reassure people with rotator cuff-related shoulder pain: a 3-arm, randomised, online experiment

ABSTRACT

We aimed to investigate the immediate effect of best practice education (with and without pain science messages) and structure-focused education on reassurance among people with rotator cuff-related shoulder pain. We conducted a 3-arm, parallel-group, randomised experiment. People with rotator cuff-related shoulder pain were randomised (1:1:1) to (1) best practice education (highlights that most shoulder pain is not serious or a good indicator of tissue damage and recommends simple self-management strategies); (2) best practice education plus pain science messages (which attempt to improve understanding of pain); and (3) structure-focused education (highlighting that structural changes are responsible for pain and should be targeted with treatment). Coprimary outcomes were self-reported reassurance that no serious condition is causing their pain and continuing with daily activities is safe. Secondary outcomes measured management intentions, credibility and relevance of the education, and similarity to previous education. Two thousand two hundred thirty-seven participants were randomised and provided primary outcome data. Best practice education increased reassurance that no serious condition is causing their pain (estimated mean effect 0.5 on a 0-10 scale, 95% confidence interval [CI] 0.2-0.7) and continuing with daily activities is safe (0.6, 95% CI 0.3-0.8) compared with structure-focused education . Adding pain science messages to best practice education slightly increased both measures of reassurance (0.2, 95% CI 0.0-0.4). Clinicians treating patients with rotator cuff-related shoulder pain should highlight that most shoulder pain is not serious or a good indicator of tissue damage and recommend simple self-management strategies. The benefit of adding pain science messages is small.

Differentiating Shoulder Pathology from Cervical Spine Pathology: An Algorithmic Approach

Accurate and timely diagnosis of musculoskeletal conditions is an essential component of high-quality orthopaedic care. The proximity of the shoulder to the cervical spine leads to a multitude of pathologic conditions whose clinical presentations overlap, posing a diagnostic challenge to orthopaedic providers. Missed or delayed diagnosis of the etiology for patient-described 'shoulder pain' causes frustration among patients, incurs increased healthcare costs, and delays treatment. Moreover, patients with concurrent conditions of the cervical spine and shoulder require deliberate consideration for how each condition contributes to patients' symptoms. The purpose of this review was to describe a systematic approach for evaluating and differentiating pathologies of the shoulder and cervical spine.

Co-development and evaluation of the Musculoskeletal Telehealth Toolkit for physiotherapists

INTRODUCTION

In-person physiotherapy services are not readily available to all individuals with musculoskeletal conditions, especially those in rural regions or with time-intensive responsibilities. The COVID-19 pandemic highlighted that telehealth may facilitate access to, and continuity of care, yet many physiotherapists lack telehealth confidence and training. This project co-developed and evaluated a web-based professional development toolkit supporting physiotherapists to provide telehealth services for musculoskeletal conditions.

METHODS

A mixed-methods exploratory sequential design applied modified experience-based co-design methods (physiotherapists [n = 13], clinic administrators [n = 2], and people with musculoskeletal conditions [n = 7]) to develop an evidence-informed toolkit. Semi-structured workshops were conducted, recorded, transcribed, and thematically analysed, refining the toolkit prototype. Subsequently, the toolkit was promoted via webinars and social media. The usability of the toolkit was examined with pre-post surveys examining changes in confidence, knowledge, and perceived telehealth competence (19 statements modelled from the theoretical domains framework) between toolkit users (>30 min) and non-users (0 min) using chi-squared tests for independence. Website analytics were summarised.

RESULTS

Twenty-two participants engaged in co-design workshops. Feedback led to the inclusion of more patient-facing resources, increased assessment-related visual content, streamlined toolkit organisation, and simplified, downloadable infographics. Three hundred and twenty-nine physiotherapists from 21 countries completed the baseline survey, with 172 (52%) completing the 3-month survey. Toolkit users had greater improvement in knowledge, confidence, and competence than non-users in 42% of statements. Seventy-two percentage of toolkit users said it changed their practice, and 95% would recommend the toolkit to colleagues. During the evaluation period, the toolkit received 5486 total views.

DISCUSSION

The co-designed web-based Musculoskeletal Telehealth Toolkit is a professional development resource that may increase physiotherapist's confidence, knowledge, and competence in telehealth.

Comparison of triamcinolone and methylprednisolone efficacy and steroid flare reaction rates after shoulder corticosteroid injection: a prospective interrupted time series study

BACKGROUND

A corticosteroid flare reaction is a well-described phenomenon that causes significant pain and dysfunction. The paucity of literature impedes decision making regarding which corticosteroid to use for shoulder injection. The purpose of this study was to compare methylprednisolone acetate (MPA) and triamcinolone acetonide (TA) injections in the glenohumeral joint and/or subacromial space in terms of efficacy and the incidence of steroid flare reactions.

METHODS

In this prospective, interrupted time series, parallel study, patients received injections in the glenohumeral joint and/or subacromial space. MPA and TA were used during 2 discrete 3-month periods. The injections consisted of 2 mL of lidocaine, 2 mL of bupivacaine, and 80 mg of either MPA or TA. Visual analog scale (VAS) pain scores were recorded immediately before injection; 1-7 days after injection; and 3, 6, and 12 months after injection. The primary outcome was the incidence of a steroid flare reaction, defined as a post-injection increase in the VAS score by ≥2 points. The secondary outcome was injection failure, defined as a post-injection VAS score greater than the baseline score or the need for another intervention. We used linear mixed models with a patient-level random intercept to identify the mean VAS score change for TA injections in the first week after injection.

RESULTS

MPA or TA shoulder injections were administered in 421 patients; of these patients, 15 received bilateral-joint injections whereas 406 received a single-joint injection, for a total of 436 injections (209 MPA and 227 TA injections). Pain scores in the first week after injection were available for 193 MPA and 199 TA injections. Significantly more patients in the MPA cohort reported flare reactions compared with the TA cohort (22.8% vs. 4.0%, P < .001) during the first week after injection. In the first week after injection, the mean VAS score of patients receiving TA injections was 1.05 (95% confidence interval, 0.47-1.63) lower than that of patients receiving MPA injections when adjusted for age, sex, race, pain type, surgeon type, and injection site. At 3 months, surveys for 169 MPA and 172 TA injections were completed, with no significant difference in the rate of injection failure for MPA vs. TA (42.6% vs. 36.1%, P = .224). Treatment failure rates were significantly higher for MPA than for TA at 6 months (78.44% vs. 62.5%, P < .001) but not at 12 months (81.18% vs. 81.42%, P = .531.) CONCLUSION: TA injections resulted in a >5-fold reduction in steroid flare reactions, with statistically superior 6-month efficacy rates, compared with MPA injections. This study supports TA as a more viable corticosteroid option for shoulder injection.

Exploration of the Usual Care Pathway for Rotator Cuff Related Shoulder Pain in the Western Australian Workers' Compensation System

PURPOSE

Investigate components of care for rotator cuff related shoulder pain in workers' compensation in relation to claim outcomes (claim duration, total medical spend, total claim cost, return to work outcome).

METHODS

Engagement with (had care, time to care) four components of care (prescribed exercise, imaging, injections, surgery) were obtained from auditing 189 closed workers' compensation files. Associations were analysed between components of care and claim outcomes.

RESULTS

80% received prescribed exercise, 81% imaging, 42% injection and 35% surgery. Median time to imaging (11 days) was shorter than the prescribed exercise (27 days), with injection at 38 days and surgery 118.5 days. With univariable regression analysis higher age, the involvement of legal representation and the presence of rotator cuff pathology from diagnostic imaging (partial thickness tear or full thickness tear) were all associated with increased claim duration, total medical spend, total claim cost and less successful return to work outcomes. After adjusting for these three associations, having an injection or surgery were both positively associated with longer claim duration and greater medical spend, and surgery with greater total claim costs. In general, longer time to receiving components of care was associated with increased claim duration and reduced odds of returning to full duties at work.

CONCLUSION

Early management was not consistent with clinical guidelines for managing workers' compensation rotator cuff related shoulder pain. This may negatively affect claims outcomes.

Anatomic characteristics of shoulder based on MRI accurately predict incomplete rotator cuff injuries in patients: relevance for predictive, preventive, and personalized healthcare strategies

Background and PPPM-related working hypothesis

In the diagnosis of incomplete rotator cuff injuries (IRCI), magnetic resonance imaging (MRI) and ultrasound examination often have false-positive and false-negative results, while arthroscopy is expensive, invasive, and complex. From the strategy of predictive, preventive, and personalized medicine (PPPM), shoulder anatomical characteristics based on MRI have been demonstrated to accurately predict IRCI and their clinical applicability for personalized prediction of IRCI.

Aims

This study aimed to develop and validate a nomogram based on anatomical features of the shoulder on MRI to identify IRCI for PPPM healthcare strategies.

Methods

The medical information of 257 patients undergoing preoperative MRI examination was retrospectively reviewed and served as the primary cohort. Partial-thickness rotator cuff tears (RCTs) and tendinopathy observed under arthroscopy were considered IRCI. Using logistic regression analyses and least absolute shrinkage and selection operator (LASSO), IRCI was identified among various preoperative factors containing shoulder MRI and clinical features. A nomogram was constructed and subjected to internal and external validations (80 patients).

Results

The following eight independent risk factors for IRCI were identified:AgeThe left injured sidesThe Goutallier classification of supraspinatus in oblique coronal positionThe Goutallier classification of supraspinatus in the axial positionAcromial thicknessAcromiohumeral distanceCoracohumeral distanceAbnormal acromioclavicular joint signalsThe nomogram accurately predicted IRCI in the development (C-index, 0.932 (95% CI, 0.891, 0.973)) and validation (C-index, 0.955 (95% CI, 0.918, 0.992)) cohorts. The calibration curve was consistent between the predicted IRCI probability and the actual IRCI ratio of the nomogram. The decision curve analysis and clinical impact curves demonstrated that the model had high clinical applicability.

Conclusions

Eight independent factors that accurately predicted IRCI were determined using MRI anatomical findings. These personalized factors can prevent unnecessary diagnostic interventions (e.g., arthroscopy) and can assist surgeons in implementing individualized clinical decisions in medical practice, thus addressing the goals of PPPM.

How do people perceive different advice for rotator cuff disease? A content analysis of qualitative data collected in a randomised experiment

OBJECTIVES

To explore how people perceive different advice for rotator cuff disease in terms of words/feelings evoked by the advice and treatment needs.

SETTING

We performed a content analysis of qualitative data collected in a randomised experiment.

PARTICIPANTS

2028 people with shoulder pain read a vignette describing someone with rotator cuff disease and were randomised to: bursitis label plus guideline-based advice, bursitis label plus treatment recommendation, rotator cuff tear label plus guideline-based advice and rotator cuff tear label plus treatment recommendation. Guideline-based advice included encouragement to stay active and positive prognostic information. Treatment recommendation emphasised that treatment is needed for recovery.

PRIMARY AND SECONDARY OUTCOMES

Participants answered questions about: (1) words/feelings evoked by the advice; (2) treatments they feel are needed. Two researchers developed coding frameworks to analyse responses.

RESULTS

1981 (97% of 2039 randomised) responses for each question were analysed. Guideline-based advice (vs treatment recommendation) more often elicited words/feelings of reassurance, having a minor issue, trust in expertise and feeling dismissed, and treatment needs of rest, activity modification, medication, wait and see, exercise and normal movements. Treatment recommendation (vs guideline-based advice) more often elicited words/feelings of needing treatment/investigation, psychological distress and having a serious issue, and treatment needs of injections, surgery, investigations, and to see a doctor.

CONCLUSIONS

Words/feelings evoked by advice for rotator cuff disease and perceived treatment needs may explain why guideline-based advice reduces perceived need for unnecessary care compared to a treatment recommendation.

Cytokines' Role in the Pathogenesis and Their Targeting for the Prevention of Frozen Shoulder: A Narrative Review

Frozen shoulder (FS) is a common name for shoulder movement limitation with different degrees of shoulder rigidity and pain. It is characterized by varying developmental courses, different levels of shoulder movement limitation, and background ambiguity due to the multiplicity of its causative factors. Systemic inflammatory cytokines monitoring and restraining is easy to apply, fast to conduct, and needs lower costs compared to invasive methods for frozen shoulder stage evaluation and early controlling of its progress to the stage that necessitates surgical intervention. The aim of this review was to assess the recent findings concerning the role of cytokines in FS pathogenesis and the possibility of preventing or controlling their progress through targeting these cytokines by the new drugs candidates, such as hyaluronan (HA), botulinum toxin type A (BoNT A), Tetrandrine, tumor necrosis factor-stimulated gene-6 (TSG-6), and cannabidiol. Searching the PubMed site, we encountered out of 1608 records, from which 16 original studies were included for the quantitative construction of this systematic review screening of the recent studies to investigate the different FS pathogenic pathways. Most of the scenarios are centered around the inflammatory and fibrotic process triggered by synovial and capsular fibroblast stimulation. This mechanism depends mainly on alarmins cytokines, including thymic stromal lymphopoietin (TSLP), interleukin-33 (IL-33), and interleukin-25 (IL-25), with the stimulation of interleukin-1 α (IL-1α), interleukin-1 β (IL-1β), tumor necrosis alpha (TNF-α), cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) in a joint capsule. Different pathways of transforming growth factor- β (TGF-β) stimulation, resulting in overexpression of the fibrotic factors as tenascin C (TNC), fibronectin 1, collagen I (COL 1) and collagen III (COL III), and matrix metalloproteinases (MMPs) in the capsular or synovial/capsular fibroblasts. The overall investigation of these studies led us to conclude that the new drug candidates proved their efficiency in controlling the common pathogenesis of the inflammatory and fibrotic pathways of frozen shoulder and therefore represent a prospect for easy and early controlling and efficiently treating this serious disease.

Knowledge and appropriateness of care of family physicians and physiotherapists in the management of shoulder pain: a survey study in the province of Quebec, Canada

BACKGROUND

Shoulder pain is difficult to diagnose and treat with half of those affected still symptomatic six months after initial consultation. This may be explained by primary care management not conforming to evidence-based practice. This survey evaluated physiotherapists (PTs) and family physicians' (FPs) knowledge and appropriateness of care in shoulder pain management.

METHODS

A survey sent to PTs and FPs in the province of Quebec, Canada presented four clinical vignettes with cases of rotator cuff (RC) tendinopathy, acute full-thickness RC tear, adhesive capsulitis and traumatic anterior glenohumeral instability. Respondents indicated diagnosis, indications for imaging, specialists' referrals, and choice of treatments. Answers were compared to recommendations from clinical practice guidelines (CPGs). Participants' responses were compared between types of providers with Fisher's exact test.

RESULTS

Respondents (PTs = 175, FPs = 76) were mostly women with less than ten years of experience. More than 80% of PTs and 84% of FPs correctly diagnosed cases presented. Despite this practice not being recommended, more FPs than PTs recommended an imaging test in the initial management of RC tendinopathy (30% compared to 13%, p = 0.001) and adhesive capsulitis (51% compared to 22%, p = 0.02). For full-thickness RC tear and shoulder instability, up to 72% of FPs and 67% of PTs did not refer to a specialist for a surgical opinion, although recommended by CPGs. For RC tendinopathy, 26% of FPs and 2% of PTs (p < 0.001) would have prescribed a corticosteroid infiltration, which is not recommended in the initial management of this disorder. For adhesive capsulitis, significantly more FPs (76%) than PTs (62%) (p < 0.001) suggested an intra-articular corticosteroid infiltration, as recommended by CPGs. For all presented vignettes, up to 95% of family physicians adequately indicated they would refer patients for physiotherapy. In prioritizing rehabilitation interventions, up to 42% of PTs did not consider active exercises as a priority and up to 65% selected passive modalities that are not recommended for all shoulder pain vignettes.

CONCLUSIONS

Most FPs and PTs were able to make adequate diagnoses and select appropriate treatments for shoulder pain, but practices opposed to evidence-based recommendations were chosen by several respondents. Further training of FPs and PTs may be needed to optimize primary care management of different shoulder disorders.

Prevalence and characteristics of musculoskeletal complaints in primary care: an analysis from the population level and analysis reporting (POLAR) database

BACKGROUND

Electronic health record datasets have been used to determine the prevalence of musculoskeletal complaints in general practice but not to examine the associated characteristics and healthcare utilisation at the primary care level.

AIM

To describe the prevalence and characteristics of patients presenting to general practitioners with musculoskeletal complaints.

DESIGN AND SETTING

A five-year analysis within three Primary Health Networks (PHNs) in Victoria, Australia.

METHOD

We included patients with at least one face-to-face consultation 2014 to 2018 inclusive and a low back (≥ 18 years), and/or neck, shoulder or knee (≥ 45 years) complaint determined by SNOMED codes derived from diagnostic text within the medical record. We determined prevalence, socio-demographic characteristics and diagnostic codes for patients with an eligible diagnosis; and number of consultations within one year of diagnosis.

RESULTS

324,793/1,294,021 (25%) presented with at least one musculoskeletal diagnosis, of whom 41% (n = 133,279) fulfilled our inclusion criteria. There were slightly more females (n = 73,428, 55%), two-thirds (n = 88,043) were of working age (18-64 years) and 83,816 (63%) had at least one comorbidity. Over half had a low back diagnosis (n = 76,504, 57%) followed by knee (n = 33,438, 25%), shoulder (n = 26,335, 20%) and neck (n = 14,492, 11%). Most codes included 'pain' and/or 'ache' (low back: 58%, neck: 41%, shoulder: 32%, knee 26%). Median (IQR) all-cause consultations per patient within one year of diagnosis was 7 (4-12).

CONCLUSION

The burden of MSK complaints at the primary care level is high as evidenced by the prevalence of people with musculoskeletal complaints presenting to a general practitioner, the preponderance of comorbidities and the numerous consultations per year. Identification and evaluation of strategies to reduce this burden are needed.

Ultrasound-guided versus landmark-guided subacromial corticosteroid injections for rotator cuff related shoulder pain: A systematic review of randomised controlled trials

INTRODUCTION

Rotator cuff related shoulder pain (RCRSP) is the most common presentation of shoulder pain within physiotherapy. Corticosteroid injections (CSI) have become increasingly popular to reduce pain, increase range of motion (ROM) and improve shoulder function. Evidence around the use of ultrasound-guided (USG) versus landmark-guided (LMG) CSIs remains controversial.

OBJECTIVE

The objective of this appraisal was to compare the effectiveness of each approach in the management of RCRSP.

METHODS

Cochrane, PubMed and CINAHL electronic databases were searched (from January 2014 to February 2021). Randomised controlled trials (RCTs) were included comparing USG to LMG CSIs for RCRSP. An independent reviewer selected the studies, extracted and synthesised the data. Two reviewers carried out a quality appraisal. Outcome measures were pain, function and ROM.

RESULTS

Four RCTs (n = 179 participants, n = 184 shoulders) were reviewed. Both USG and LMG groups showed statistically significant within group improvements in clinical outcomes. There were no significant differences between groups. Three studies were identified as being a 'low' risk of bias (RoB) and did not favour the use of ultrasound. One study did favour the use of ultrasound for improving function, although it was found to have 'high' RoB. Adverse events were seldom reported.

CONCLUSION

There is limited evidence to suggest using USG CSIs has a superior effect on clinical outcomes compared to LMG, though small sample sizes and lack of long-term follow-up limit the generalisability of the findings.

The environmental impact of health care for musculoskeletal conditions: A scoping review

BACKGROUND

Health care has significant environmental impact. We performed a scoping review to map what is known about the environmental impact of health care for musculoskeletal conditions.

METHODS

We included published papers of any design that measured or discussed environmental impact of health care or health support services for any musculoskeletal condition in terms of climate change or global warming (e.g., greenhouse gas emissions it produces). We searched MEDLINE and Embase from inception to 2 May 2022 using keywords for environmental health and musculoskeletal conditions, and performed keyword searches using Google and Google Scholar. Two independent reviewers screened studies. One author independently charted data, verified by a second author. A narrative synthesis was performed.

RESULTS

Of 12,302 publications screened and 73 identified from other searches, 122 full-text articles were assessed for eligibility, and 49 were included (published 1994 to 2022). Of 24 original research studies, 11 measured environmental impact relating to climate change in orthopaedics (n = 10), and medical aids for the knee (n = 1), one measured energy expenditure of laminar versus turbulent airflow ventilation systems in operating rooms during simulated hip replacements and 12 measured waste associated with orthopaedic surgery but did not relate waste to greenhouse gas emissions or environmental effects. Twenty-one editorials described a need to reduce environmental impact of orthopaedic surgery (n = 9), physiotherapy (n = 9), podiatry (n = 2) or occupational therapy (n = 1). Four narrative reviews discussed sustainability relating to hand surgery (n = 2), orthopaedic surgery (n = 1) and orthopaedic implants (n = 1).

CONCLUSION

Despite an established link between health care and greenhouse gas emissions we found limited empirical data estimating the impact of musculoskeletal health care on the environment. These data are needed to determine whether actions to lower the carbon footprint of musculoskeletal health care should be a priority and to identify those aspects of care that should be prioritised.

Diagnostic labels and advice for rotator cuff disease influence perceived need for shoulder surgery: an online randomised experiment

QUESTION

What are the effects of diagnostic labels and advice, and interactions between labels and advice, on perceived need for shoulder surgery for rotator cuff disease?

DESIGN

2×2 factorial online randomised experiment.

PARTICIPANTS

People with shoulder pain.

INTERVENTION

Participants read a scenario describing a patient with rotator cuff disease and were randomised to bursitis label plus guideline-based advice, bursitis label plus treatment recommendation, rotator cuff tear label plus guideline-based advice, and rotator cuff tear label plus treatment recommendation. Guideline-based advice included encouragement to stay active and positive prognostic information. Treatment recommendation stressed that treatment is needed for recovery.

OUTCOME MEASURES

Perceived need for surgery (primary outcome), imaging, an injection, a second opinion and to see a specialist; and perceived seriousness of the condition, recovery expectations, impact on work performance and need to avoid work.

RESULTS

A total of 2,024 responses (99.8% of 2,028 randomised) were analysed. Labelling as bursitis (versus rotator cuff tear) decreased perceived need for surgery (mean effect -0.5 on a 0-to-10 scale, 98.3% CI -0.7 to -0.2), imaging and to see a specialist, and perceived seriousness of the condition and need to avoid work. Guideline-based advice (versus treatment recommendation) decreased perceived need for surgery (mean effect -1.0, 98.3% CI -1.3 to -0.7), imaging, an injection, a second opinion and to see a specialist, and perceived seriousness of the condition and recovery expectations. There was little to no evidence of an advice label interaction for any outcome.

CONCLUSION

Labels and advice influenced perceived need for surgery and other secondary outcomes in people with rotator cuff disease, with larger effects for advice. There was evidence of little or no interaction between labels and advice for any outcome, but the additive effect of labels and advice appeared large for some outcomes (eg, perceived need for imaging and perceived seriousness of the condition).

Subacromial Injections of Low- or High-Molecular-Weight Hyaluronate Versus Physical Therapy for Shoulder Tendinopathy: A Randomized Triple-Blind Controlled Trial

OBJECTIVE

Shoulder tendinopathy is a prevalent and debilitating problem. We compared the effects of subacromial high- or low-molecular-weight hyaluronate injection with physical therapy (PT) in shoulder tendinopathy.

DESIGN

A triple-blinded randomized controlled trial.

SETTING

We conducted the trial in an outpatient clinic at a teaching hospital.

PARTICIPANTS

In total, 79 patients with shoulder tendinopathy were randomly allocated to high- (n = 27) or low-molecular-weight (n = 28) hyaluronate or PT (n = 24) groups.

INTERVENTIONS

We administered a 20-mg injection of high- or low-molecular-weight hyaluronate. For PT, we prescribed 10 sessions of physiotherapy and exercise.

OUTCOME MEASURES

The primary outcome was shoulder pain and the secondary outcomes included Disability of the Arm Shoulder and Hand score, shoulder range of movement and QoL. We measured the outcomes at baseline, 1, and 3 months of treatment, and assessed shoulder pain at the sixth month postintervention.

RESULTS

The interventions were all clinically beneficial in the management of tendinopathy for high- (n = 25) and low-molecular-weight (n = 24) hyaluronate and PT (n = 19) groups (all P < 0.05). However, between-group analyses indicated that hyaluronate preparations were more effective in controlling pain, decreasing disability, increasing range of motion, and improving the quality of life (all P < 0.05). The pain and subjective feeling of rigidity at the injection area ( P = 0.012) were less prominent for low-molecular-weight hyaluronate.

CONCLUSION

High- or low-molecular-weight hyaluronate is more effective than PT in the treatment of shoulder tendinopathy. The clinical benefits of hyaluronate last for at least 3 months, and the pain alleviation sustains partially for 6 months. Shoulder injection of low-molecular-weight hyaluronate is more tolerable to the patient than high-molecular-weight hyaluronate.

Managing shoulder pain: a meta-ethnography exploring healthcare providers' experiences

OBJECTIVE

To review and synthesize qualitative research studies exploring the experiences of Healthcare Providers (HCPs) of managing shoulder pain.

METHODS

A meta-ethnographic approach was adopted to review and synthesize eligible studies. The findings from each included study were translated into one another using Noblit and Hares' seven-stage process. A systematic search of eleven electronic databases was conducted in February 2021. Methodological quality was assessed using the CASP Appraisal Tool.

RESULTS

Ten studies were included in the meta-synthesis, all deemed of high methodological quality. Three themes were identified; (1) Lack of consensus: "we all have different approaches." (2) Challenges to Changing Practice: It's "really hard to change and switch to a different approach," (3) Getting "Buy in" to Treatment: "…so you have to really sell it early".

CONCLUSION

Healthcare providers working with people with shoulder pain struggle to reconcile, often conflicting, research recommendations with their own clinical experience, beliefs and patient expectations. These findings help explain the continued lack of consensus on how best to manage shoulder pain in clinical practice.IMPLICATIONS FOR REHABILITATIONHealthcare providers (HCPs) working with people with shoulder pain struggle to resolve conflicts between evidence-based recommendations, clinical experience, their own shoulder pain beliefs and patient expectations and preferences.Stronger collaboration across professional disciplines is needed to address the current lack of consensus on the management of shoulder pain.Many HCP's find it difficult to engage patients with shoulder pain in exercise and they work hard to "sell" this approach to patients using strategies such as education, shared decision making and therapeutic alliance.

The use and safety of corticosteroid injections for shoulder pain in general practice: a retrospective cohort study

BACKGROUND

Guidelines for shoulder pain in general practice recommend treatment with corticosteroid injections (CSI) if initial pain management fails. However, little is known about the actual use and safety of CSIs in treatment by general practitioners (GP).

OBJECTIVE

The objective of this study was to gain insight into the use and safety of CSIs for patients with a new episode of shoulder pain in general practice.

METHODS

A retrospective cohort study was conducted using a healthcare database containing the electronic medical records of approximately 200,000 patients in general practice. A search algorithm was constructed to identify patients with a new episode of shoulder pain between January 2012 and December 2017. Data on the use of CSIs in 2 random samples (n = 1,000) were manually validated for a 12-month period after the diagnosis.

RESULTS

In total, 26% of the patients with a new episode of shoulder pain received a CSI. The patient's age (OR 1.03, 95% CI 1.02-1.04) and a history of shoulder pain (OR 1.52, 95% CI 1.13-2.12) were significantly associated with the administration of a CSI. Half of the patients received the CSI in the first consultation. The patient's age was positively associated with the likelihood of receiving the CSI in the first consultation (OR 1.01, 95% CI 1.00-1.02). No serious adverse reactions were recorded by the GP.

CONCLUSION

In contrast to the guidelines, CSIs were frequently administered in the first consultation. Older patients and patients with a history of shoulder pain were more likely to receive a CSI for shoulder pain.

'Down to the person, the individual patient themselves': A qualitative study of treatment decision-making for shoulder pain

Introduction

Many inconsistencies have been identified in the translation of evidence‐based treatment recommendations for musculoskeletal shoulder pain into healthcare services, with little known about factors influencing decision‐making. The objective of this study was to explore the views and experiences of healthcare providers (HCPs) and people living with shoulder pain on treatment decision‐making.

Methods

Adopting a qualitative design, purposeful sampling was employed to recruit 13 individuals with nonspecific musculoskeletal shoulder pain and 30 HCPs. Data were collected through 1:1 semi‐structured interviews and analysed using an approach informed by Constructivist Grounded Theory. To facilitate analysis, two patient and public involvement (PPI) meetings were conducted.

Results

Most participants (69%) had shoulder pain of ≥1‐year duration. Biomechanical beliefs about shoulder pain predominated and were heavily influential in decision‐making for both patients and HCPs. Despite a consensus that therapeutic alliance facilitated decision‐making, the extent of collaboration between HCPs and patients in treatment decision‐making was rather limited. In addition to condition‐specific factors, Individual patient characteristics and resources also influenced treatment decisions.

Conclusion

Findings revealed the complexity of the decision‐making process for both patients and HCPs, exposing substantial gaps between the reported views and experiences of participants and the principles of client‐centred and evidence‐based practice. There is a pressing need to enhance the translation of evidence‐based knowledge into practice in this clinical area.

Patient or Public Contribution

In line with a consultative approach to collaborative data analysis, a subgroup of participants attended two PPI meetings to provide commentary and feedback on preliminary findings.

How do people perceive different labels for rotator cuff disease? A content analysis of data collected in a randomised controlled experiment

OBJECTIVES

Explore how people perceive different labels for rotator cuff disease in terms of words or feelings evoked by the label and treatments they feel are needed.

SETTING

We performed a content analysis of qualitative data collected in a six-arm, online randomised controlled experiment.

PARTICIPANTS

1308 people with and without shoulder pain read a vignette describing a patient with rotator cuff disease and were randomised to one of six labels: subacromial impingement syndrome, rotator cuff tear, bursitis, rotator-cuff-related shoulder pain, shoulder sprain and episode of shoulder pain.

PRIMARY AND SECONDARY OUTCOMES

Participants answered two questions (free-text response) about: (1) words or feelings evoked by the label; (2) what treatments they feel are needed. Two researchers iteratively developed coding frameworks to analyse responses.Results1308/1626 (80%) complete responses for each question were analysed. Psychological distress (21%), uncertainty (22%), serious condition (15%) and poor prognosis (9%) were most often expressed by those labelled with subacromial impingement syndrome. For those labelled with a rotator cuff tear, psychological distress (13%), serious condition (9%) and poor prognosis (8%) were relatively common, while minor issue was expressed least often compared with the other labels (5%). Treatment/investigation and surgery were common among those labelled with a rotator cuff tear (11% and 19%, respectively) and subacromial impingement syndrome (9% and 10%) compared with bursitis (7% and 5%).

CONCLUSIONS

Words or feelings evoked by certain labels for rotator cuff disease and perceived treatment needs may explain why some labels drive management preferences towards surgery and imaging more than others.

Corticosteroid injection or dry needling for musculoskeletal pain and disability? A systematic review and GRADE evidence synthesis

Background

Corticosteroid injection and dry needling have been used in the treatment of musculoskeletal conditions, but it is unclear which intervention is the most effective. The purpose of this study was to compare the effects of corticosteroid injection and dry needling for musculoskeletal conditions at short-, medium-, and long-term follow-up.

Methods

Electronic databases were searched up to 31 October 2021. Two researchers independently screened titles, abstracts and full-text articles. Randomized clinical trials (RCTs) that investigated the effectiveness of dry needling compared to corticosteroid injection in patients over 18 years with a musculoskeletal condition were included in the review. The studies had to report pain and/or disability as outcome. Risk of bias was assessed by using the revised Cochrane Collaboration tool (RoB 2.0). Quality of evidence was evaluated by using the GRADE approach.

Results

Six studies were included (n = 384 participants). Four musculoskeletal conditions were investigated. There is very low-quality evidence that CSI is superior to DN for reducing heel pain (plantar fasciitis) and lateral elbow pain at short- and medium-term follow-up, but not for myofascial pain and greater trochanteric pain. There is very low-quality evidence that DN is more effective than CSI at long-term follow-up for reducing pain in people with plantar fasciitis and lateral epicondylitis. Very low-certainty evidence shows that there is no difference between DN and CSI for disability at short-term follow-up. One study showed that CSI is superior to DN at medium-term follow-up and another observed that DN is superior to CSI for reducing disability at long-term.

Conclusions

There are no differences between DN and CSI in pain or disability for myofascial pain and greater trochanteric pain syndrome. Very-low certainty evidence suggests that CSI is superior to DN at shorter follow-up periods, whereas DN seems to be more effective than CSI at longer follow-up durations for improving pain in plantar fasciitis and lateral epicondylitis. Large RCTs with higher methodological quality are needed in order to draw more incisive conclusions.

Low Molecular-weight Hyaluronic Acid Versus Physiotherapy for the Treatment of Supraspinatus Tendinopathy: A Randomized Comparative Clinical Trial

INTRODUCTION

The tendons of the rotator cuff are major sources of shoulder pain. This study aimed to compare the effects of low molecular-weight hyaluronic acid with physiotherapy (PT) in patients with supraspinatus tendinopathy (ST).

METHODS

We carried out a parallel two-group randomized comparative clinical trial in an outpatient clinic of physical medicine and rehabilitation at a teaching hospital. In total, 51 patients (31 women) aged 20 to 55 years with ST were randomly allocated to subacromial hyaluronate injection (n = 28) and PT (n = 23) groups. For the hyaluronate group, we administered a single injection of 2 mL (20 mg) hyaluronate 1% (500 to 700 kDa). For PT, we prescribed three sessions of treatment per week for 12 weeks, totaling 36 sessions including rotator cuff activation exercises. The primary outcome was shoulder pain in the visual analog scale. The secondary outcomes included the range of movement and the disability score of the shoulder, and a World Health Organization questionnaire on quality of life. We did the measurements at the baseline and at one, four, and 12 weeks after intervention.

RESULTS

The results showed that both interventions were beneficial in the management of ST. However, hyaluronate was more effective in reducing shoulder pain at rest and during activities (both P < 0.001, effect size = 0.52 and 0.68, respectively). The two interventions similarly decreased patients' disability (P = 0.196). Hyaluronate improved shoulder motion and the quality of life better than PT.

CONCLUSION

In the treatment of ST, low molecular-weight hyaluronate is more effective than PT, at least for three months. Particularly, hyaluronate is more successful in alleviating pain.

The incidence and management of shoulder complaints in general practice: a retrospective cohort study

BACKGROUND

Shoulder pain is the third most common musculoskeletal complaint in primary care. The international guidelines for general practitioners (GPs) recommend a stepwise treatment of shoulder pain. Little is known about the actual distribution of these treatments in current practice.

OBJECTIVE

To gain insight in the incidence and current management of shoulder complaints in Dutch general practice.

METHODS

A retrospective cohort study was conducted using a health care database containing the full electronic medical records of approximately 200 000 patients in Dutch general practice. A search algorithm was constructed to identify incident cases of shoulder complaints from January 2012 to December 2017. Data on the management of shoulder complaints were manually validated in a random sample of 1000 cases.

RESULTS

The overall incidence of shoulder complaints was 30.3 (95% confidence interval 29.9-30.7) per 1000 person-years. More than half of the patients (58.6%) consulted their GP only once, 44.4% two times or more and 19.7% three times or more. For most patients (58.1%), the GP applied a wait-and-see policy or prescription of oral medication in the first consultation. However, no less than 42.9% of the patients were referred or received an injection already in the first consultation.

CONCLUSIONS

There is a wide variety of treatments for shoulder complaints applied by the GP. Some patients are referred or received an injection already in the first consultation. The stepwise approach recommended by the guideline, might not always be applicable due to the diversity of patient- and shoulder characteristics presented in general practice.

Patterns of care for people presenting to Australian general practice with musculoskeletal complaints based on routinely collected data: protocol for an observational cohort study using the Population Level Analysis and Reporting (POLAR) database

INTRODUCTION

General practice is integral to the Australian healthcare system. Outcome Health's POpulation Level Analysis and Reporting (POLAR) database uses de-identified electronic health records to analyse general practice data in Australia. Previous studies using routinely collected health data for research have not consistently reported the codes and algorithms used to describe the population, exposures, interventions and outcomes in sufficient detail to allow replication. This paper reports a study protocol investigating patterns of care for people presenting with musculoskeletal conditions to general practice in Victoria, Australia. Its focus is on the systematic approach used to classify and select eligible records from the POLAR database to facilitate replication. This will be useful for other researchers using routinely collected health data for research.

METHODS AND ANALYSIS

This is a retrospective cohort study. Patient-related data will be obtained through electronic health records from a subset of general practices across three primary health networks (PHN) in southeastern Victoria. Data for patients with a low back, neck, shoulder and/or knee condition and who received at least one general practitioner (GP) face-to-face consultation between 1 January 2014 and 31 December 2018 will be included. Data quality checks will be conducted to exclude patients with poor data recording and/or non-continuous follow-up. Relational data files with eligible and valid records will be merged to select the study cohort and the GP care received (consultations, imaging requests, prescriptions and referrals) between diagnosis and 31 December 2018. Number and characteristics of patients and GPs, and number, type and timing of imaging requests, prescriptions for pain relief and referrals to other health providers will be investigated.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Cabrini and Monash University Human Research Ethics Committees (Reference Numbers 02-21-01-19 and 16975, respectively). Study findings will be reported to Outcome Health, participating PHNs, disseminated in academic journals and presented in conferences.

Management of recent onset tendon-related pain in a primary contact setting: A survey of practice

BACKGROUND

Tendon-related pain is a common and debilitating condition that affects a wide range of people. To inform future research, it is important to understand healthcare professional's current practice.

OBJECTIVES

To describe the practice of First Contact Practitioners (FCPs) and Other Clinicians (OCs) for recent onset tendon pain in a primary contact setting. The secondary aim was to understand if practice differed between the locations of pain.

DESIGN

Cross-sectional online survey METHOD: The online survey asked for responses relating to one scenario of shoulder pain and one of Achilles pain. Except location of pain, the scenarios were identical. Responses were collected over a four-week period to December 2020. The Chi-Square test was used to analyse the difference in proportion of responses between FCPs and OCs, and between locations of pain.

RESULTS

118 responses were received. Rotator Cuff Related Shoulder Pain (RCRSP) was preferred by 64/118 (54.2%) for the shoulder scenario. Achilles tendinopathy was the preferred term by 86/103 (83.5%) for the Achilles. FCPs were more likely to advise NSAIDs for both shoulder (p = 0.006) and Achilles (p = 0.046) scenarios than OCs. Amended duties were more likely to be advised for manual workers for the shoulder scenario compared to Achilles (p = <0.0001).

CONCLUSION

There were similarities in the management of recent onset tendon-related pain; the majority of respondents recommended against further investigations, steroid injections, and recommended exercise. Understanding whether these approaches are clinically effective requires further investigation.

Clinical practice guidelines for the management of atraumatic shoulder conditions: protocol for a systematic review

INTRODUCTION

Shoulder conditions are a major cause of morbidity in the general population. Many clinical practice guidelines (CPGs) for shoulder conditions have been developed. Their purpose is to provide evidence-based recommendations to assist clinicians in providing optimal care to maximise patient outcomes. The aim of this systematic review is to identify, appraise, and compare the content and quality of CPGs for atraumatic shoulder conditions.

METHODS AND ANALYSIS

CPGs for atraumatic shoulder conditions will be included provided they make recommendations about diagnosis and/or management, are identified by their authors as a guideline and are consistent with the Appraisal of Guidelines for Research and Evaluation (AGREE) II definition of a guideline. A systematic search of electronic databases, online guideline repositories and the websites of relevant professional societies will be conducted to identify eligible CPGs. Search terms relating to shoulder conditions (eg, 'adhesive capsulitis', 'rotator cuff' and 'bursitis') will be combined with a validated search filter for CPGs. Pairs of independent reviewers will determine eligibility of CPGs identified by the search. Quality appraisal of included CPGs will be performed using the AGREE II instrument. Recommendations from each CPG and how they were determined will be extracted and compared across similar CPGs. Results from this systematic review will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement.

ETHICS AND DISSEMINATION

Ethical approval is not required for this systematic review. The results from this study will be published in a peer-reviewed journal and disseminated to professional societies that publish shoulder CPGs, clinical policy groups, clinicians, researchers and consumers.

Patient knowledge of rotator cuff related shoulder pain condition and treatment and validation of a patient-reported knowledge questionnaire

BACKGROUND

Rotator cuff related shoulder pain (RCRSP) knowledge is an important contributor to compliance with clinical practice guidelines and providing best practice care. However, there are no validated instruments for measuring health literacy levels among people with RCRSP. This study aimed to design a valid and reliable instrument to measure RCRSP health literacy and use it to evaluate an education intervention for people with RCRSP.

METHODS

Development of the patient knowledge questionnaire (PKQ-RCRSP) included three phases. Phase 1 was developed based on available literature and input from expert clinicians, researchers and patients. Face validity, pilot testing and readability assessment were also undertaken. In Phase 2, internal consistency and predictive validity were assessed in people with RCRSP and other shoulder pain diagnoses. In Phase 3, RCRSP health literacy was assessed.

RESULT

Face validity was acceptable and pilot testing identified minor accuracy issues that were corrected. Literacy level was rated as 'difficult to read' which reflects the medical terminology within the questionnaire. Internal consistency was very good and 81% of questions demonstrated acceptable predictive validity. Health literacy was heterogeneous depending on the question with less than 40% of respondents answering correctly for questions related to the indications, process and the known benefits of RCRSP surgery.

CONCLUSION

The PKQ-RCRSP demonstrated acceptable face validity, predictive validity and reliability (internal consistency) in assessing RCRSP health literacy. Health literacy among our small sample was poor for questions related to surgery for RCRSP.

High- Versus Low-Molecular-Weight Hyaluronic Acid for the Treatment of Rotator Cuff Tendinopathy: A Triple-Blind Randomized Comparative Trial

BACKGROUND

Shoulder pain most commonly originates from the tendon structures of the rotator cuff.

OBJECTIVE

We compared the clinical effects of high- versus low-molecular-weight (LMW) hyaluronic acid for the management of rotator cuff tendinopathy.

METHODS

We carried out a parallel, triple-blind, randomized comparative trial at a teaching hospital. In total, 56 patients aged 16 to 70 years with rotator cuff tendinopathy were randomly allocated to 2 groups. We administered a single shoulder injection of either 1 mL of 1% high- (>2000 kDa) or 1 mL of 1% LMW hyaluronate (500-700 kDa) to the corresponding groups. The primary outcome was the intensity of shoulder pain. The secondary outcomes were range of motion and disability of the shoulder, and quality of life. We performed the measurements at baseline and at 1, 4, and 12 weeks postintervention. The pain measurements were repeated at the sixth month postintervention.

RESULTS

Comparisons of baseline versus 3 months showed that both interventions were beneficial in the management of the tendinopathy (all P values <0.05). However, between-group analyses did not indicate any clinically significant difference between the 2 medications. The pain, induration (P = 0.007), and inflammation at the site of the injection were less prominent for LMW hyaluronate.

CONCLUSION AND RELEVANCE

Both medications are effective for the treatment of tendinopathy. The benefits last at least for 3 months, and pain alleviation lasts partially for 6 months. The shoulder injection of LMW hyaluronate is more tolerable to the patient. Therefore, we recommend LMW hyaluronate as the first choice for the management of rotator cuff tendinopathy.

'Physio's not going to repair a torn tendon': patient decision-making related to surgery for rotator cuff related shoulder pain

BACKGROUND

Rotator cuff related shoulder pain (RCRSP) is a common and disabling shoulder condition and surgical management is becoming more common. The rates and costs of surgical interventions have been on the rise. Understanding decision-making related to surgery and providing adequate information to people with RCRSP may improve patient-centred care and potentially reduce rates of surgery.

OBJECTIVES

To explore the decision-making processors of people who have undertaken surgery for RCRSP.

DESIGN

An in-depth thematic analysis.

METHOD

Interviews were conducted with patients from Melbourne who had had surgical management for RCRSP. Data were analysed using an inductive thematic approach.

RESULTS

Fifteen participants were recruited. Six key themes emerged: (1) Needing to get it done: "It was necessary to remedy the dire situation"; (2) Non-surgical treatment experience:" I knew that I'd done all I could"; (3) Mechanical problem:" Physio's not going to repair a torn tendon"; (4) Trust in medical professionals "If they told me that I needed to swallow a thousand spiders, I would have done it."; (5) Varied information sources "Dr Google played a big part in it"; (6) Organisational barriers "It was absolutely useless, my insurance."

CONCLUSION

Surgery appears to be commonly precipitated by unremitted severe symptoms and failed non-surgical treatment. While there was strong trust in highly trained surgeons, decision to undergo surgery also drew on questionable pathoanatomical beliefs and instances of inadequate patient information about treatment choices and risks that may be addressed by adopting a more patient-centred care approach.IMPLICATIONS FOR REHABILITATIONUnderstanding decision-making related to surgery and providing adequate information to people with rotator cuff related shoulder pain may improve patient-centred care.Surgery appears to be commonly precipitated by unremitted severe symptoms and failed non-surgical treatment.Decision to undergo surgery sometimes drew on questionable pathoanatomical beliefs.There was strong trust in highly trained surgeons but there were instances of inadequate patient information about treatment choices and risks.

Self-reported management among people with rotator cuff related shoulder pain: An observational study

BACKGROUND

Rotator cuff related shoulder pain is the most common cause of shoulder pain. Whilst guidelines recommend conservative management prior to imaging, injection or surgical management, recent findings suggest that patients experience management contrary to guideline recommendations.

OBJECTIVES

The aim of this study was to investigate self-reported management among people with rotator cuff related shoulder pain (RCRSP) and their beliefs towards management.

MATERIALS AND METHODS

Cross-sectional survey of people with RCRSP recruited when referred for imaging (n = 120). Electronic survey about demographic factors, management people had had (including imaging, injections, surgery, exercise, adjuncts), and beliefs about treatments. The frequency of various treatments was reported (separately for each cohort and traumatic onset) as well as the timing of interventions related to first-line care.

RESULTS

Most people had tried exercise (99/120, 82.5%) but only one in five people reported exercise was helpful, and one in six reported it was unhelpful or made their symptoms worse. Approximately a third of the cohort reported not receiving activity modification advice (34.2%, 41/120), those that did received inconsistent information. People with both traumatic (imaging 31/43, 72.1%; injections 13/24, 54.2%, surgery 8/21, 38.1%) and atraumatic onset pain (imaging 43/77, 55.8%; injections 31/51, 60.8%, surgery 4/19, 21.1%) had similarly high rates of intervention prior to trialling conservative management. Patient beliefs in regards to management showed trends towards interventionalist care.

CONCLUSION

Patient reported management of RCRSP is often inconsistent with guideline recommended management.

What Is the Diagnosis in Patients with Type 2 Diabetes Who Have a Painful Shoulder? Results from a Prospective Cross-Sectional Study

Background: Patients with diabetes mellitus have higher risk of developing shoulder pathology. However, only adhesive capsulitis is addressed in shoulder pain guidelines as a disorder associated with diabetes. Yet, patients with diabetes are at risk of having several other shoulder disorders, including focal neuropathy. Our aim was to quantify the presence of shoulder disorders using physical examination and ultrasound imaging in patients with type 2 diabetes (T2DM) suffering from shoulder pain in general practice. Methods: In this prospective cross-sectional study, patients with T2DM who had had a painful shoulder for at least four weeks were included. Patients filled out a questionnaire and underwent a physical examination of the shoulders and feet and ultrasound imaging of the shoulder. Results: A total of 66 patients were included, of whom 40.9% (n = 27) had bilateral complaints resulting in 93 symptomatic shoulders. Subacromial pain syndrome was most frequently diagnosed by physical examination (66.6%, 95% CI 51.6–72.0%; p < 0.0001), while ultrasound imaging showed that subacromial disorders were statistically significantly the most prevalent (90.3%, 95% CI 81.9–95.2%). Only two patients (3%) were diagnosed with neuropathic shoulder pain. Conclusion: When choosing treatment, general practitioners should be aware that in patients with T2DM the subacromial region is most frequently affected.

'He explains it in a way that I have confidence he knows what he is doing': A qualitative study of patients' experiences and perspectives of rotator-cuff-related shoulder pain education

BACKGROUND

Patient education is recommended in clinical practice guidelines for rotator-cuff-related shoulder pain (RCRSP), yet there are no guidelines for clinicians. A gap in the current literature relates to patients' perspectives.

AIMS

The aim of this study was to explore the experiences and perspectives of people with RCRSP about education for their condition.

MATERIALS AND METHODS

An inductive qualitative design was adopted. Eight participants with RCRSP participated in individual telephone interviews that were audio-recorded, transcribed and de-identified. Four researchers completed inductive thematic analysis. Institutional ethics approval was obtained.

RESULTS

Results are detailed as a thematic analysis from the interview responses. Three primary themes were identified: (1) a therapeutic alliance leads to trust of education; (2) education of RCRSP should be individualized and practical; and (3) delivery of educational interventions should be varied and multi-modal.

DISCUSSION

The results demonstrated that trust in the health professional providing the education facilitates adherence and increases belief that the condition is being effectively treated. Participants believed imaging were necessary for an individual diagnosis despite clinical practice guidelines not recommending imaging for the first 6-12 weeks of initial presentation. There was a general caution about generic online information which may adversely impact the value of exclusively online educational intervention in the future. Participants preferred clear and practical education about RCRSP, including activity modification, timeframes for recovery and potential detriments to their recovery. There was consensus that education is best delivered early in the rehabilitation process, however there were mixed preferences for delivery method between written, video and face-to-face which perhaps reflects different learning styles and indicates that a 'one size fits all' approach is not effective in adult education in this condition.

CONCLUSION

People with RCRSP believe education about their condition is important and is best delivered by a trusted source early in their rehabilitation. There is a belief that scans are necessary to provide an individualized diagnosis and assists in their understanding of the condition. There is an opportunity for online education; however, this may best be utilised as an adjunct method to face-to-face care.

Internet and Telerehabilitation-Delivered Management of Rotator Cuff-Related Shoulder Pain (INTEL Trial): Randomized Controlled Pilot and Feasibility Trial

BACKGROUND

Rotator cuff-related shoulder pain (RCRSP) is a common and disabling musculoskeletal condition. Internet-based and telerehabilitation delivery of recommended care may improve access to care and improve adherence and outcomes.

OBJECTIVE

The primary aim of this pilot randomized controlled trial was to assess the feasibility of a 12-week internet-delivered intervention for RCRSP comparing advice only, recommended care, and recommended care with group-based telerehabilitation.

METHODS

Reporting was in accordance with the Consolidated Standards of Reporting Trials (CONSORT) checklist for pilot and feasibility trials. People with a primary complaint of RCRSP for 3 months or longer were identified via a paid Facebook strategy. Screening involved an online questionnaire followed by a 20-minute telehealth assessment. Participants were randomly allocated (via a Zelen design) to receive (1) advice only, (2) recommended care (internet-delivered evidence-based exercise and education), or (3) recommended care and telerehabilitation (including a weekly group teleconference session). Progression criteria for a full-scale trial included (1) recruitment of 20% or greater of eligible participants, (2) acceptable adherence (two or more of the three prescribed weekly sessions) among 70% or greater of participants, (3) 80% or greater retention of participants, (4) absence of intervention-related serious adverse events, and (5) 80% or greater response rates to questionnaires. Secondary clinical and patient knowledge outcomes were collected (via email or text) at baseline, six weeks, and 12 weeks (for clinical and patient knowledge), and within-group change was reported descriptively.

RESULTS

We enrolled 36 of 38 (95%) eligible participants and all participants were recruited within a 3-week period. Of the 36 participants, 12 participants were allocated to each of the three trial arms. The mean age of participants was between 51 and 56 years, and 83% (10/12) to 92% (11/12) were female. Retention at the 12-week endpoint was 94% (34/36) and response to email questionnaires at other time points was 83% or greater. We found acceptable adherence (defined as greater than 70% of participants performing exercise 2 or 3 times/week) in the recommended care group with telerehabilitation but not in the recommended care group without telerehabilitation. There was a total of 24 adverse events over 108 person-months of observation. All adverse events were mild or moderate (mainly muscle and shoulder symptoms), with the exception of one instance of elective surgery (unrelated to the person's shoulder condition).

CONCLUSIONS

Our prespecified success criteria were met or exceeded, but there was a gender imbalance toward women. It is feasible to progress to a fully powered trial, but strategies to address the gender imbalance need to be implemented.
