Therapeutic exercise for rotator cuff tendinopathy: a systematic review of contextual factors and prescription parameters

Shoulder mobility and strength impairments in patients with rotator cuff related shoulder pain: a systematic review and meta analysis

Background

The methods previously proposed in the literature to assess patients with rotator cuff related shoulder pain, based on special orthopedic tests to precisely identify the structure causing the shoulder symptoms have been recently challenged. This opens the possibility of a different way of physical examination.

Objective

To analyze the differences in shoulder range of motion, strength and thoracic kyphosis between rotator cuff related shoulder pain patients and an asymptomatic group.

Method

The protocol of the present research was registered in the International Prospective Register of Systematic Review (PROSPERO) (registration number CRD42021258924). Database search of observational studies was conducted in MEDLINE, EMBASE, WOS and CINHAL until July 2023, which assessed shoulder or neck neuro-musculoskeletal non-invasive physical examination compared to an asymptomatic group. Two investigators assessed eligibility and study quality. The Newcastle Ottawa Scale was used to evaluate the methodology quality.

Results

Eight studies (N = 604) were selected for the quantitative analysis. Meta-analysis showed statistical differences with large effect for shoulder flexion (I2 = 91.7%, p < 0.01, HG = -1.30), external rotation (I2 = 83.2%, p < 0.01, HG = -1.16) and internal rotation range of motion (I2 = 0%, p < 0.01, HG = -1.32). Regarding to shoulder strength; only internal rotation strength showed statistical differences with small effect (I2 = 42.8%, p < 0.05, HG = -0.3).

Conclusions

There is moderate to strong evidence that patients with rotator cuff related shoulder pain present less shoulder flexion, internal and external rotation range of motion and less internal rotation strength than asymptomatic individuals.

Is exercise therapy the right treatment for rotator cuff-related shoulder pain? Uncertainties, theory, and practice

BACKGROUND

Exercise therapy is a popular non-surgical treatment to help manage individuals with rotator cuff-related shoulder pain (RCRSP) and is recommended in all clinical practice guidelines. Due to modest effect sizes, low quality evidence, uncertainty relating to efficacy, and mechanism(s) of benefit, exercise as a therapeutic intervention has been the subject of increasing scrutiny.

AIMS

The aim of this critical review is to lay out where the purported uncertainties of exercise for RCRSP exist by exploring the relevant quantitative and qualitative literature. We conclude by offering theoretical and practical considerations to help reduce the uncertainty of delivering exercise therapy in a clinical environment.

RESULTS AND DISCUSSION

Uncertainty underpins much of the theory and practice of delivering exercise therapy for individuals with RCRSP. Nonetheless, exercise is an often-valued treatment by individuals with RCRSP, when provided within an appropriate clinical context. We encourage clinicians to use a shared decision-making paradigm and embrace a pluralistic model when prescribing therapeutic exercise. This may take the form of using exercise experiments to trial different exercise approaches, adjusting, and adapting the exercise type, load, and context based on the individual's symptom irritability, preferences, and goals.

CONCLUSION

We contend that providing exercise therapy should remain a principal treatment option for helping individuals with RCRSP. Limitations notwithstanding, exercise therapy is relatively low cost, accessible, and often valued by individuals with RCRSP. The uncertainty surrounding exercise therapy requires ongoing research and emphasis could be directed towards investigating causal mechanisms to better understand how exercise may benefit an individual with RCRSP.

Shoulder specific exercise therapy is effective in reducing chronic shoulder pain: A network meta-analysis

BACKGROUND

Exercise therapy (ET) is frequently an early treatment of choice when managing shoulder pain, yet evidence on its efficacy to expedite recovery is inconsistent. Moreover, the value of adding adjunct therapies (i.e. injections, manual therapy, electrotherapy) to ET is currently unclear. This study combined both direct and indirect evidence across studies on the effectiveness of ET with/without adjunct therapies compared to usual medical care for adults with chronic shoulder pain.

METHODS AND FINDINGS

Using a network meta-analysis, randomized control trials comparing ET along with adjunct therapies were identified in MEDLINE, Embase, CINAHL, Sportdiscus, CENTRAL, Conference Proceedings Citation Index-Science, clinicaltrials.gov, and association websites. Outcomes included pain, range of motion (ROM), and health-related quality of life (HRQL) measures in adult patients with chronic shoulder pain. Data analysis used a Frequentist hierarchical model. CINeMA tool assessed the confidence in the results and Cochrane Risk of Bias tool assessed quality of studies. 54 studies primarily from Europe (40.38%) included 3,893 participants who were followed up to 52 weeks. Shoulder-specific ET (Mean difference (MD) = -2.1; 95% confidence interval (CI) = -3.5 to -0.7) or in combination with electro-physical agents (MD = -2.5; 95% CI = -4.2 to -0.7), injections (MD = -2.4; 95% CI = -3.9 to-1.04) or manual therapy (MD = -2.3; 95% CI = -3.7 to -0.8) decreased pain compared to usual medical care. Trends with ROM and HRQL scores were seen; however, only Manual Therapy (MD = -12.7 and 95% CI = -24.4 to -1.0) achieved meaningfully important changes. Sensitivity analysis excluding studies with high risk of bias showed similar results, with exception of injections that did not reach significance (MD = -1.3; 95% CI = -4.3 to 1.7).

CONCLUSION(S)

Shoulder-specific ET provided pain relief up to 52 weeks. Adjunct therapies to shoulder-specific ET added little value in reducing pain. The quality of evidence varied between moderate and very low.

Therapeutic exercises in the clinical practice of Brazilian physical therapists in the management of rotator cuff tendinopathy: An online survey

The objective of this study was to investigate how Brazilian physical therapists (PTs) use therapeutic exercises in the rehabilitation of individuals with rotator cuff (RC) tendinopathy. The study used an online survey with a mix of 62 open- and closed-ended questions divided into three sections: participant demographics, professional experience, and clinical practice in the rehabilitation of patients with RC tendinopathy. One hundred and fifty-nine Brazilian physical therapists completed the survey. Most of our sample recommended isometric exercises (69.9%) in the initial phase of rehabilitation and eccentric exercises (47.4%) in the advanced phase. However, there was a wide variability in determining the volume of exercises, particularly with isometric exercises. Most of our sample considered patient comfort and pain levels when adjusting exercise intensity, regardless of exercise type. The majority (48.40%) recommended weekly reassessment and modification of exercises. Additionally, despite pain being a key factor for discharge and the primary adverse effect of exercise, most of our sample would not discontinue exercises in case of pain during the early and late phases of rehabilitation. Despite the lack of consensus on some aspects, the clinical practice of our sample is in line with the current literature and practice in other countries. However, further research and implementation are crucial to enhance future rehabilitation outcomes, including exploring the exercise training volume, the safety and effectiveness of exercising with pain and identifying the optimal pain level for best results.

Reproducibility of Exercise Interventions in Randomized Controlled Trials for the Treatment of Rotator Cuff-Related Shoulder Pain: A Systematic Review

OBJECTIVE

To determine the reproducibility of exercise therapy interventions in randomized controlled trials for rotator cuff-related shoulder pain (RCRSP).

DATA SOURCES

Data sources included Medline, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials, and SPORTDiscus from studies published from database inception to April 23, 2022.

STUDY SELECTION

Randomized controlled trials studying the use of exercise therapy for RCRSP.

DATA EXTRACTION

Two reviewers extracted exercise reporting details from all studies using the Template for Intervention Description and Replication (TIDieR) and the modified Consensus on Exercise Reporting Template (CERT). The same 2 reviewers assessed risk of bias of all studies using Cochrane Risk of Bias Tool version 2.0.

DATA SYNTHESIS

For 104 studies meeting inclusion criteria, the average number of items reported on the TIDieR was 5.27 (SD 2.50, range 1-12 out of 12) and 5.09 (SD 4.01, range 0-16 out of 16) on the CERT. Improved reporting over time was seen on both the TIDieR and CERT dating back to 1993 and through April 23, 2022. When comparing groups of studies published before and after the TIDieR (2014) and CERT (2016) were established, a statistically significant increase in median scores was noted on the TIDieR (P=.02) but not the CERT (P=.31). Quality of exercise therapy reporting was highest in studies with "low risk" of bias, and lowest in studies with "high risk" of bias on the RoB-2.

CONCLUSION

Overall exercise reporting in trials for RCRSP is incomplete despite the development of the TIDieR and CERT checklists. This has implications for translating evidence into practice.

To allow or avoid pain during shoulder rehabilitation exercises for patients with chronic rotator cuff tendinopathy-Study protocol for a randomized controlled trial (the PASE trial)

BACKGROUND

Rotator cuff (RC) tendinopathy is the most reported shoulder disorder in the general population with highest prevalence in overhead athletes and adult working-age population. A growing body of evidence support exercise therapy as an effective intervention, but to date there are no prospective randomized controlled trials addressing pain as an intervention variable.

METHODS

A single-site, prospective, pragmatic, assessor-blinded randomized controlled superiority trial. Eighty-four patients aged 18-55 years with chronic (symptom duration over 3 months) RC tendinopathy are randomized 1:1 to receive shoulder exercise during which pain is either allowed or avoided. The intervention period lasts 26 weeks. During that period, participants in both groups are offered 8 individual on-site sessions with an assigned sports physiotherapist. Participants perform home exercises and are provided with a pain and exercise logbook and asked to report completed home-based exercise sessions and reasons for not completing sessions (pain or other reasons). Patients are also asked to report load and the number of sets and repetitions per sets for each exercise session. The logbooks are collected continuously throughout the intervention period. The primary and secondary outcomes are obtained at baseline, 6 weeks, 26 weeks, and 1 year after baseline. The primary outcome is patient-reported pain and disability using the Shoulder PAin and Disability Index (SPADI). Secondary outcomes are patient-reported pain and disability using Disability Arm Shoulder and Hand short-form (Quick DASH), and shoulder pain using Numeric Pain Rating Scale. Objective outcomes are shoulder range of motion, isometric shoulder muscle strength, pain sensitivity, working ability, and structural changes in the supraspinatus tendon and muscle using ultrasound.

DISCUSSION

The results of this study will contribute knowledge about the treatment strategies for patients with RC tendinopathy and help physiotherapists in clinical decision-making. This is the first randomized controlled trial comparing the effects of allowing pain versus avoiding pain during shoulder exercises in patients with chronic RC tendinopathy. If tolerating pain during and after exercise proves to be effective, it will potentially expand our understanding of "exercising into pain" for this patient group, as there is currently no consensus.

Blood Flow Restriction Training in Patients With Rotator Cuff Tendinopathy: A Randomized, Assessor-Blinded, Controlled Trial

OBJECTIVES

To investigate the effects of low-load blood flow restriction (BFR) training on shoulder muscle thickness, rotator cuff (RC) strength, and shoulder symptoms in patients with RC tendinopathy.

DESIGN

A randomized, assessor-blinded, controlled trial.

SETTINGS

Physiotherapy clinic at a university.

PARTICIPANTS

Twenty-eight patients were randomized into an 8-week (2 times/week) shoulder rehabilitation, that is, BFR or non-BFR group.

INTERVENTIONS

BFR training.

MAIN OUTCOME MEASURES

(1) RC, deltoid, scapula retractor, and biceps muscle thicknesses and shoulder internal rotation (IR) and external rotation (ER) strengths. (2) Shoulder pain/function.

RESULTS

The BFR group had a greater increase in biceps muscle thickness ( P = 0.002) and shoulder IR strength at 60 degrees/s ( P = 0.040) than the non-BFR group. No differences between the 2 groups were observed in other measurements. Significant improvements in supraspinatus, infraspinatus, and scapula retractor muscle thicknesses and in shoulder ER and IR strengths were observed over time in both the groups (all P < 0 .05). Also, shoulder pain decreased and shoulder function increased over time in both the groups (all P < 0 .05).

CONCLUSIONS

Low-load BFR training resulted in a greater increase in biceps thickness and shoulder IR strength compared with the non-BFR group in patients with RC tendinopathy. However, there was no superiority of either exercise training regarding the RC, scapula retractor, deltoid muscle thicknesses, or improvements in shoulder ER strength and shoulder pain/function.

CLINICAL TRIAL REGISTRY NAME AND REGISTRATION NUMBER

The study was registered in ClinicalTrials.gov named Blood Flow Restriction Training in Patients with Shoulder Pain and the registration number is NCT04333784.

Which Psychological and Psychosocial Constructs Are Important to Measure in Future Tendinopathy Clinical Trials? A Modified International Delphi Study With Expert Clinician/Researchers and People With Tendinopathy

OBJECTIVE: To identify which psychological and psychosocial constructs to include in a core outcome set to guide future clinical trials in the tendinopathy field. DESIGN: Modified International Delphi study. METHODS: In 3 online Delphi rounds, we presented 35 psychological and psychosocial constructs to an international panel of 38 clinician/researchers and people with tendinopathy. Using a 9-point Likert scale (1 = not important to include, 9 = critical to include), consensus for construct inclusion required ≥70% of respondents rating "extremely critical to include" (score ≥7) and ≤15% rating "not important to include" (score ≤3). Consensus for exclusion required ≥70% of respondents rating "not important to include" (score ≤3) and ≤15% of rating "critical to include" (score ≥7). RESULTS: Thirty-six participants (95% of 38) completed round 1, 90% (n = 34) completed round 2, and 87% (n = 33) completed round 3. Four constructs were deemed important to include as part of a core outcome set: kinesiophobia (82%, median: 8, interquartile range [IQR]: 1.0), pain beliefs (76%, median: -7, IQR: 1.0), pain-related self-efficacy (71%, median: 7, IQR: 2.0), and fear-avoidance beliefs (73%, median: -7, IQR: 1.0). Six constructs were deemed not important to include: perceived injustice (82%), individual attitudes of family members (74%), social isolation and loneliness (73%), job satisfaction (73%), coping (70%), and educational attainment (70%). Clinician/researchers and people with tendinopathy reached consensus that kinesiophobia, pain beliefs, pain self-efficacy, and fear-avoidance beliefs were important psychological constructs to measure in tendinopathy clinical trials.

Low-level laser therapy versus ultrasound therapy combined with home-based exercise in patients with subacromial impingement syndrome: A randomized-controlled trial

Objectives

The aim of this study was to evaluate the effects of low-level laser therapy (LLLT) and therapeutic ultrasound (US) combined with home-based exercise (HBE) versus HBE alone in patients with subacromial impingement syndrome (SAIS).

Patients and methods

Between March 2021 and July 2021, a total of 60 patients with SAIS (19 males, 41 females; mean age: 51.3±10.4 years; range, 30 to 70 years) were included. The patients were randomly allocated to an LLLT group (LG), an US therapy group (UG), and a control group (CG). The LLLT and US therapy programs were applied five times a week, for a total of 15 sessions. Home-based exercise programs and cold-pack therapy were administered to patients in each group. The patients were evaluated at baseline and one and three months of follow-up using the Visual Analog Scale (VAS) for pain during activity, at rest, and at night, and the Shoulder Pain and Disability Index (SPADI).

Results

All groups showed a significant improvement in the VAS and SPADI scores after the first month (p<0.05). The VAS activity pain score (p=0.008), SPADI pain score (p=0.003), SPADI disability score (p=0.012), and SPADI total score (p=0.003) significantly decreased in the LG compared to the CG at one month of follow-up. However, there were no significant differences in the outcome measures among the three groups at three months (p>0.05).

Conclusion

The LLLT combined with HBE is more effective than HBE program alone for relieving activity pain and improving shoulder functions in the short term. However, LLLT and US therapy do not provide additional effects in terms of pain and disability at three months.

Content reporting and effectiveness of therapeutic exercise in the management of massive rotator cuff tears: A systematic review with 490 patients

Background

Massive rotator cuff tears (MRCT) account for a substantial fraction of tears above the age of 60 years. However, there are no clear criteria for prescription parameters within therapeutic exercise treatments. The aim of this study was to evaluate the effects and characteristics of therapeutic exercise treatments in patients with MRCT.

Methods

A systematic search was conducted in MEDLINE/PubMed, Web of Science, SPORTDiscus, SciELO, Scopus and EMBASE from inception to August 2022. Studies were included if they evaluated the effects of exercise on patients with MRCT. The risk of bias was evaluated and the Consensus on Exercise Reporting Template (CERT) was also used. A narrative synthesis without meta-analysis was performed.

Results

One randomized controlled trial, two non-randomized studies, six non-controlled studies, one case series and four retrospective studies were included. They ranged from serious to moderate risk of bias. The CERT reflected a poor description of the exercise programmes. Studies showed a pattern of improvements in most patient-reported outcome measures (PROM) surpassing the MCID, and active elevation range of motion.

Conclusions

There is limited evidence that exercise and co-interventions are effective in the management of some patients with MRCT, based on a systematic review without meta-analysis. Future research should improve content reporting.

Level of evidence

Exercise into pain in chronic rotator cuff related shoulder pain: a prospective single-group feasibility study

OBJECTIVES

This study evaluated the feasibility of exercising into pain in rotator cuff related shoulder pain (RCRSP), data collection procedures, feedback from physiotherapists and patients, and clinically important changes in patient-reported outcome measures (PROMs).

DESIGN

Unblinded non-randomised single-group study.

SETTING

Physiotherapy clinic in Belgium.

PARTICIPANTS

Twelve patients with unilateral RCRSP for minimum 3 months, aged 18-65 years.

INTERVENTIONS

Twelve weeks of four individualised exercises, with nine physiotherapist-led sessions with pain ratings 4-7 out of 10 on a verbal Numeric Pain Rating Scale for 9 weeks and then pain ratings 0-2 for 3 weeks. Every physiotherapy session included 15 min of manual therapy. Non-supervised exercises were: 2×/week in weeks with physiotherapy session, 3×/week in weeks without physiotherapy session.

OUTCOME MEASURES

Primary: adherence, where patients were considered adherent with 78% (7/9 sessions) attendance for supervised sessions and 81% (22/27 sessions) completion for non-supervised exercises, and Shoulder Pain and Disability Index (SPADI); secondary: fear-avoidance behaviour, fear of pain, physical outcomes (strength, range of motion, scapular dyskinesis); others: ultrasound (US) imaging outcomes (acromionhumeral distance, supraspinatus tendon thickness, occupation ratio), global perceived effect (GPE). PROMs were collected via online survey, except for the GPE (via closed envelope). US measures were taken after physical measures.

RESULTS

Adherence and adverse effects were analysed in patients who had the possibility to attend minimum seven supervised sessions (n=8): 88% of them adhered to supervised sessions, 50% to non-supervised exercises; none of them withdrew from the study, three of them obtained individual clinically important improvements in SPADI score above 20 points. The measurement protocol of physical and ultrasonographic outcomes took around 60 min.

CONCLUSIONS

Adherence to supervised sessions was satisfactory, the adherence to non-supervised exercises must be improved. Data collection procedures were feasible to perform, but some changes are recommended.

Exercise therapy for tendinopathy: a mixed-methods evidence synthesis exploring feasibility, acceptability and effectiveness

Background

Tendinopathy is a common, painful and functionally limiting condition, primarily managed conservatively using exercise therapy.

Review questions

(i) What exercise interventions have been reported in the literature for which tendinopathies? (ii) What outcomes have been reported in studies investigating exercise interventions for tendinopathy? (iii) Which exercise interventions are most effective across all tendinopathies? (iv) Does type/location of tendinopathy or other specific covariates affect which are the most effective exercise therapies? (v) How feasible and acceptable are exercise interventions for tendinopathies?

Methods

A scoping review mapped exercise interventions for tendinopathies and outcomes reported to date (questions i and ii). Thereafter, two contingent systematic review workstreams were conducted. The first investigated a large number of studies and was split into three efficacy reviews that quantified and compared efficacy across different interventions (question iii), and investigated the influence of a range of potential moderators (question iv). The second was a convergent segregated mixed-method review (question v). Searches for studies published from 1998 were conducted in library databases (n = 9), trial registries (n = 6), grey literature databases (n = 5) and Google Scholar. Scoping review searches were completed on 28 April 2020 with efficacy and mixed-method search updates conducted on 19 January 2021 and 29 March 2021.

Results

Scoping review - 555 included studies identified a range of exercise interventions and outcomes across a range of tendinopathies, most commonly Achilles, patellar, lateral elbow and rotator cuff-related shoulder pain. Strengthening exercise was most common, with flexibility exercise used primarily in the upper limb. Disability was the most common outcome measured in Achilles, patellar and rotator cuff-related shoulder pain; physical function capacity was most common in lateral elbow tendinopathy. Efficacy reviews - 204 studies provided evidence that exercise therapy is safe and beneficial, and that patients are generally satisfied with treatment outcome and perceive the improvement to be substantial. In the context of generally low and very low-quality evidence, results identified that: (1) the shoulder may benefit more from flexibility (effect sizeResistance:Flexibility = 0.18 [95% CrI 0.07 to 0.29]) and proprioception (effect sizeResistance:Proprioception = 0.16 [95% CrI -1.8 to 0.32]); (2) when performing strengthening exercise it may be most beneficial to combine concentric and eccentric modes (effect sizeEccentricOnly:Concentric+Eccentric = 0.48 [95% CrI -0.13 to 1.1]; and (3) exercise may be most beneficial when combined with another conservative modality (e.g. injection or electro-therapy increasing effect size by ≈0.1 to 0.3). Mixed-method review - 94 studies (11 qualitative) provided evidence that exercise interventions for tendinopathy can largely be considered feasible and acceptable, and that several important factors should be considered when prescribing exercise for tendinopathy, including an awareness of potential barriers to and facilitators of engaging with exercise, patients' and providers' prior experience and beliefs, and the importance of patient education, self-management and the patient-healthcare professional relationship.

Limitations

Despite a large body of literature on exercise for tendinopathy, there are methodological and reporting limitations that influenced the recommendations that could be made.

Conclusion

The findings provide some support for the use of exercise combined with another conservative modality; flexibility and proprioception exercise for the shoulder; and a combination of eccentric and concentric strengthening exercise across tendinopathies. However, the findings must be interpreted within the context of the quality of the available evidence.

Future work

There is an urgent need for high-quality efficacy, effectiveness, cost-effectiveness and qualitative research that is adequately reported, using common terminology, definitions and outcomes.

Effect of resistance exercise dose components for tendinopathy management: a systematic review with meta-analysis

OBJECTIVE

To investigate potential moderating effects of resistance exercise dose components including intensity, volume and frequency, for the management of common tendinopathies.

DESIGN

Systematic review with meta-analysis and meta-regressions.

DATA SOURCES

Including but not limited to: MEDLINE, CINAHL, SPORTDiscus, ClinicalTrials.gov and ISRCTN Registry.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Randomised and non-randomised controlled trials investigating resistance exercise as the dominant treatment class, reporting sufficient information regarding ≥2 components of exercise dose.

RESULTS

A total of 110 studies were included in meta-analyses (148 treatment arms (TAs), 3953 participants), reporting on five tendinopathy locations (rotator cuff: 48 TAs; Achilles: 43 TAs; lateral elbow: 29 TAs; patellar: 24 TAs; gluteal: 4 TAs). Meta-regressions provided consistent evidence of greater pooled mean effect sizes for higher intensity therapies comprising additional external resistance compared with body mass only (large effect size domains: β BodyMass: External = 0.50 (95% credible interval (CrI): 0.15 to 0.84; p=0.998); small effect size domains (β BodyMass: External = 0.04 (95% CrI: -0.21 to 0.31; p=0.619)) when combined across tendinopathy locations or analysed separately. Greater pooled mean effect sizes were also identified for the lowest frequency (less than daily) compared with mid (daily) and high frequencies (more than once per day) for both effect size domains when combined or analysed separately (p≥0.976). Evidence for associations between training volume and pooled mean effect sizes was minimal and inconsistent.

SUMMARY/CONCLUSION

Resistance exercise dose is poorly reported within tendinopathy management literature. However, this large meta-analysis identified some consistent patterns indicating greater efficacy on average with therapies prescribing higher intensities (through inclusion of additional loads) and lower frequencies, potentially creating stronger stimuli and facilitating adequate recovery.

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

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

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.

Pain neuroscience education in persistent painful tendinopathies: A scoping review from the Tendon PNE Network

OBJECTIVE

to conduct and report a scoping review of the available evidence of the effects and content of pain neuroscience education for patients with persistent painful tendinopathies.

METHODS

PubMed, Embase, Web of Science, CINAHL, SPORTDiscus, and grey literature databases were searched from database inception to May 2022. Randomised and non-randomised controlled trials, non-controlled clinical trials, cohort studies, case series, case studies including people with persistent painful tendinopathy aged ≥18 years, a pain education intervention, and in English were included. Studies were excluded if they were cross-sectional studies, reviews, editorials, abstracts, or full-text not available or if included heterogeneous study cohorts, patients with tendon rupture, or patients with systemic diseases.

RESULTS

five studies (n = 164) were included. Pain neuroscience education entailed face-to-face discussion sessions or educational materials including videos, brochures, paper drawings, and review questions. All studies used pain neuroscience education in conjunction with other interventions, obtaining significant benefits in outcomes related to pain, physical performance, or self-reported function, among others.

CONCLUSIONS

The application of pain neuroscience education in conjunction with other interventions seemed to improve several outcomes. However, considering the current knowledge about tendon pain and the scarcity of well-designed trials studying pain neuroscience education in tendinopathy, additional research is needed.

What are small, medium and large effect sizes for exercise treatments of tendinopathy? A systematic review and meta-analysis

Objective

To quantify and describe effect size distributions from exercise therapies across a range of tendinopathies and outcome domains to inform future research and clinical practice through conducting a systematic review with meta-analysis.

Design

Systematic review with meta-analysis exploring moderating effects and context-specific small, medium and large thresholds.

Eligibility criteria

Randomised and quasi-randomised controlled trials involving any persons with a diagnosis of rotator cuff, lateral elbow, patellar, Achilles or gluteal tendinopathy of any severity or duration.

Methods

Common databases, six trial registries and six grey literature databases were searched on 18 January 2021 (PROSPERO: CRD42020168187). Standardised mean difference (SMD_pre) effect sizes were used with Bayesian hierarchical meta-analysis models to calculate the 0.25 (small), 0.5 (medium) and 0.75 quantiles (large) and compare pooled means across potential moderators. Risk of bias was assessed with Cochrane's Risk of Bias tool.

Results

Data were obtained from 114 studies comprising 171 treatment arms 4104 participants. SMD_pre effect sizes were similar across tendinopathies but varied across outcome domains. Greater threshold values were obtained for self-reported measures of pain (small=0.5, medium=0.9 and large=1.4), disability (small=0.6, medium=1.0 and large=1.5) and function (small=0.6, medium=1.1 and large=1.8) and lower threshold values obtained for quality of life (small=-0.2, medium=0.3 and large=0.7) and objective measures of physical function (small=0.2, medium=0.4 and large=0.7). Potential moderating effects of assessment duration, exercise supervision and symptom duration were also identified, with greater pooled mean effect sizes estimated for longer assessment durations, supervised therapies and studies comprising patients with shorter symptom durations.

Conclusion

The effect size of exercise on tendinopathy is dependent on the type of outcome measure assessed. Threshold values presented here can be used to guide interpretation and assist with further research better establishing minimal important change.

Muscle fatigue response of rotator cuff muscles in different postures

INTRODUCTION

Muscle fatigue is a leading cause of rotator cuff (RC) pathologies. Scapular orientation affected by changes in the thoracic spine account for differences in body postures leading to altered RC muscle activation. This posture-related alteration in RC muscle activation and its fatigue response needs to be analyzed.

MATERIALS AND METHODS

This study included 50 healthy shoulders with no coexisting spine pathologies. Raw data were recorded using electromyography sensors for RC muscles during two isometric maneuvers of abduction and external rotation, performed at 30% maximum voluntary contraction at 30°, 45°, and 90° arm elevation in sitting and standing. The raw data were analyzed in DataLITE^® software, and the mean power frequency (MPF) was extracted to analyze the fatigue response of RC muscles. The Wilcoxon signed-rank test and Kruskal-Wallis test with Bonferroni corrections analyzed fatigue differences between postures and various activities. P < 0.05 was considered significant for the results.

RESULTS

Supraspinatus muscle demonstrated significant fatigue at 90° of arm elevation in standing as compared to sitting (MPF -5.40: -5.41; P = 0.03) posture. Between the three elevation angles, all the RC muscles showed increased fatigue at 90° (MPF range -5.22 to -6.64). When compared between abduction and external rotation, only infraspinatus showed fatigue in external rotation (MPF range -5.42 to -6.08). Among all the three RC muscles, infraspinatus showed the maximum fatigue of MPF -6.64 when compared to supraspinatus -5.22 and teres minor -5.36.

CONCLUSION

The findings indicate that alterations in the body postures and different elevation angles affect the RC muscles' fatigue response.

Increased shoulder pain across an exercise session and subsequent shoulder exercise: a prospective cohort study

Background

Shoulder complaints are common and the recommended first-line treatment is exercise therapy. However, it remains unknown if increased shoulder pain after an exercise session is a barrier for subsequent exercise dose, particularly in people with high fear-avoidance beliefs. Such knowledge could indicate ways to optimise shoulder rehabilitation. The aim was to examine whether increased shoulder pain across an exercise session was associated with a lower subsequent exercise dose, and if high fear-avoidance beliefs exaggerated this association.

Methods

We conducted a prospective cohort study using data from a randomised controlled trial in Central Denmark Region 2017–2019. Participants were employees (n = 79) with shoulder complaints and high occupational shoulder exposures. The intervention was a home-based or partly supervised exercise programme lasting 2–3 months. Linear mixed models were used to examine the associations between change in shoulder pain and exercise dose (number of repetitions, progression level (1–3), resistance level (1–3), and time until next exercise session [days]).

Results

At baseline, the participants had a median pain intensity at rest of 2 on a numerical rating scale (0–10). For a 1-cm increase in pain on a visual analogue scale (0–10 cm) during an exercise session, the subsequent number of repetitions, progression level and resistance level were − 1.3 (95% confidence interval [CI] − 3.4 to 0.9), 0.0 (95% CI − 0.1 to 0.0) and − 0.0 (95% CI − 0.1 to 0.0), respectively. Likewise, the time until next exercise session was − 0.6 (95% CI − 2.4 to 1.3) days for a 1-cm increase. There were no interactions with fear-avoidance beliefs.

Conclusion

Increased pain across an exercise session was not associated with subsequent exercise dose, regardless of fear-avoidance beliefs, among employees with shoulder complaints and high occupational shoulder exposures.

Trial registration

The trial was registered at Clinicaltrials.gov 19/05/2017 (ID: NCT03159910).

Real versus Sham Manual Therapy in Addition to Therapeutic Exercise in the Treatment of Non-Specific Shoulder Pain: A Randomized Controlled Trial

The aim of this study was to evaluate if manual therapy added to a therapeutic exercise program produced greater improvements than a sham manual therapy added to same exercise program in patients with non-specific shoulder pain. This was an evaluator-blinded randomized controlled trial. Forty-five subjects were randomly allocated into one of three groups: manual therapy (glenohumeral mobilization technique and rib-cage technique); thoracic sham manual therapy (glenohumeral mobilization technique and rib-cage sham technique); or sham manual therapy (sham glenohumeral mobilization technique and rib-cage sham technique). All groups also received a therapeutic exercise program. Pain intensity, disability and pain-free active shoulder range of motion were measured post treatment and at 4-week and 12-week follow-ups. Mixed-model analyses of variance and post hoc pairwise comparisons with Bonferroni corrections were constructed for the analysis of the outcome measures. All groups reported improved pain intensity, disability and pain-free active shoulder range of motion. However, there were no between-group differences in these outcome measures. The addition of the manual therapy techniques applied in the present study to a therapeutic exercise protocol did not seem to add benefits to the management of subjects with non-specific shoulder pain.

Effects of High-Energy Extracorporeal Shockwave Therapy on Pain, Functional Disability, Quality of Life, and Ultrasonographic Changes in Patients with Calcified Rotator Cuff Tendinopathy

Objective

The current trial was designed to evaluate the effects of high-energy shockwave therapy on objective and subjective outcomes among participants with calcified rotator cuff tendinopathy.

Methods

This parallel-group, randomized trial consists of 42 patients affected by calcific tendinopathies divided into two groups of 21 participants. Patients having calcified tendinopathy aged between 30 and 65 years with type A or B calcification were selected in the trial after signing the written consent form. Participants in the ESWT+RPT group received eight sessions of shockwaves, while the RPT group was treated by routine physical therapy. About 2000 shockwaves of 0.32 mJ/mm², 120 Hz per treatment, were given as 12 sessions for the first six weeks (2 sessions/week). Pain intensity and shoulder functional ability, ultrasonographic changes, and quality of life were assessed with the numeric pain rating scale (NPRS), Constant-Murley score (CMS), ultrasonography, and Western Ontario rotator cuff index (WORC).

Results

There were significant differences regarding NPRS and CMS between the two groups, at baseline and 6th and 12th weeks after intervention (p < 0.05). Within-group differences also showed statistically significant results after treatment (all p < 0.05). Significant results were seen in the WORC and ultrasonographic results pre- and posttreatment; more significant findings were found in the experimental group as compared to others.

Conclusion

High-energy shockwave therapy has been proved to be effective and thus strongly recommended for the management of calcified rotator cuff tendinopathy, improving the pain, functionality, and quality of life of these participants and decreasing the size of calcified deposits. Shockwave therapy is proved to be superior to routine physiotherapy.

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

BACKGROUND

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

OBJECTIVE

To identify the most relevant clinical descriptors for diagnosing RCRSP.

METHODS

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

RESULTS

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

CONCLUSION

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

Comparative effectiveness of treatment options for subacromial shoulder conditions: a systematic review and network meta-analysis

Background:

There are currently many treatment options for patients with subacromial shoulder conditions (SSCs). Clinical decision-making regarding the best treatment option is often difficult. This study aims to evaluate the comparative effectiveness of treatment options for relieving pain and improving function in patients with SSCs.

Methods:

Eight databases [including MEDLINE, Embase, CINAHL, AMED, PEDro, Cochrane Database of Systematic Reviews and World Health Organization (WHO) International Clinical Trials Registry] were searched from inception until April 2020. Randomised clinical/controlled trials of adult patients investigating the effects of nonsurgical (e.g. corticosteroid injections, therapeutic exercise, shockwave therapy) and surgical treatment for SSCs, compared with each other, placebo, usual care or no treatment, were retrieved. Pairs of reviewers screened studies independently, quality appraised eligible studies using the Cochrane risk of bias tool, extracted and checked data for accuracy. Primary outcomes were pain and disability in the short term (⩽3 months) and long term (⩾6 months). Direct and indirect evidence of treatment effectiveness was synthesised using random-effects network meta-analysis.

Results:

The review identified 177 eligible trials. Summary estimates (based on 99 trials providing suitable data, 6764 patients, 20 treatment options) showed small to moderate effects for several treatments, but no significant differences on pain or function between many active treatment comparisons. The primary analysis indicated that exercise and laser therapy may provide comparative benefit in terms of both pain and function at different follow-up time-points, with larger effects found for laser in the short term at 2–6 weeks, although direct evidence was provided by one trial only, and for exercise in the longer term [standardised mean difference (SMD) 0.39, 95% confidence interval (CI) 0.18, 0.59 at 3–6 months] compared with control. Sensitivity analyses excluding studies at increased risk of bias confirmed only the comparative effects of exercise as being robust for both pain and function up until 3-month follow-up.

Conclusion:

Current evidence shows small to moderate effect sizes for most treatment options for SSCs. Six treatments had a high probability of being most effective, in the short term, for pain and function [acupuncture, manual therapy, exercise, exercise plus manual therapy, laser therapy and Microcurrent (MENS) (TENS)], but with low certainty for most treatment options. After accounting for risk of bias, there is evidence of moderate certainty for the comparative effects of exercise on function in patients with SSCs. Future large, high-quality pragmatic randomised trials or meta-analyses are needed to better understand whether specific subgroups of patients respond better to some treatments than others.

Progressive exercise compared with best-practice advice, with or without corticosteroid injection, for rotator cuff disorders: the GRASP factorial RCT

BACKGROUND

Rotator cuff-related shoulder pain is very common, but there is uncertainty regarding which modes of exercise delivery are optimal and the long-term benefits of corticosteroid injections.

OBJECTIVES

To assess the clinical effectiveness and cost-effectiveness of progressive exercise compared with best-practice physiotherapy advice, with or without corticosteroid injection, in adults with a rotator cuff disorder.

DESIGN

This was a pragmatic multicentre superiority randomised controlled trial (with a 2 × 2 factorial design).

SETTING

Twenty NHS primary care-based musculoskeletal and related physiotherapy services.

PARTICIPANTS

Adults aged ≥ 18 years with a new episode of rotator cuff-related shoulder pain in the previous 6 months.

INTERVENTIONS

A total of 708 participants were randomised (March 2017-May 2019) by a centralised computer-generated 1 : 1 : 1 : 1 allocation ratio to one of four interventions: (1) progressive exercise (n = 174) (six or fewer physiotherapy sessions), (2) best-practice advice (n = 174) (one physiotherapy session), (3) corticosteroid injection then progressive exercise (n = 182) (six or fewer physiotherapy sessions) or (4) corticosteroid injection then best-practice advice (n = 178) (one physiotherapy session).

MAIN OUTCOME MEASURES

The primary outcome was Shoulder Pain and Disability Index (SPADI) score over 12 months. Secondary outcomes included SPADI subdomains, the EuroQol 5 Dimensions, five-level version, sleep disturbance, fear avoidance, pain self-efficacy, return to activity, Global Impression of Treatment and health resource use. Outcomes were collected by postal questionnaires at 8 weeks and at 6 and 12 months. A within-trial economic evaluation was also conducted. The primary analysis was intention to treat.

RESULTS

Participants had a mean age of 55.5 (standard deviation 13.1) years and 49.3% were female. The mean baseline SPADI score was 54.1 (standard deviation 18.5). Follow-up rates were 91% at 8 weeks and 87% at 6 and 12 months. There was an overall improvement in SPADI score from baseline in each group over time. Over 12 months, there was no evidence of a difference in the SPADI scores between the progressive exercise intervention and the best-practice advice intervention in shoulder pain and function (adjusted mean difference between groups over 12 months -0.66, 99% confidence interval -4.52 to 3.20). There was also no difference in SPADI scores between the progressive exercise intervention and best-practice advice intervention when analysed at the 8-week and 6- and 12-month time points. Injection resulted in improvement in shoulder pain and function at 8 weeks compared with no injection (adjusted mean difference -5.64, 99% confidence interval -9.93 to -1.35), but not when analysed over 12 months (adjusted mean difference -1.11, 99% confidence interval -4.47 to 2.26), or at 6 and 12 months. There were no serious adverse events. In the base-case analysis, adding injection to best-practice advice gained 0.021 quality-adjusted life-years (p = 0.184) and increased the cost by £10 per participant (p = 0.747). Progressive exercise alone was £52 (p = 0.247) more expensive per participant than best-practice advice, and gained 0.019 QALYs (p = 0.220). At a ceiling ratio of £20,000 per quality-adjusted life-year, injection plus best-practice advice had a 54.93% probability of being the most cost-effective treatment.

LIMITATIONS

Participants and physiotherapists were not blinded to group allocation. Twelve-month follow-up may be insufficient for identifying all safety concerns.

CONCLUSIONS

Progressive exercise was not superior to a best-practice advice session with a physiotherapist. Subacromial corticosteroid injection improved shoulder pain and function, but provided only modest short-term benefit. Best-practice advice in combination with corticosteroid injection was expected to be most cost-effective, although there was substantial uncertainty.

FUTURE WORK

Longer-term follow-up, including any serious adverse effects of corticosteroid injection.

Progressive exercise compared with best practice advice, with or without corticosteroid injection, for the treatment of patients with rotator cuff disorders (GRASP): a multicentre, pragmatic, 2 × 2 factorial, randomised controlled trial

BACKGROUND

Corticosteroid injections and physiotherapy exercise programmes are commonly used to treat rotator cuff disorders but the treatments' effectiveness is uncertain. We aimed to compare the clinical effectiveness and cost-effectiveness of a progressive exercise programme with a single session of best practice physiotherapy advice, with or without corticosteroid injection, in adults with a rotator cuff disorder.

METHODS

In this pragmatic, multicentre, superiority, randomised controlled trial (2 × 2 factorial), we recruited patients from 20 UK National Health Service trusts. We included patients aged 18 years or older with a rotator cuff disorder (new episode within the past 6 months). Patients were excluded if they had a history of significant shoulder trauma (eg, dislocation, fracture, or full-thickness tear requiring surgery), neurological disease affecting the shoulder, other shoulder conditions (eg, inflammatory arthritis, frozen shoulder, or glenohumeral joint instability), received corticosteroid injection or physiotherapy for shoulder pain in the past 6 months, or were being considered for surgery. Patients were randomly assigned (centralised computer-generated system, 1:1:1:1) to progressive exercise (≤6 sessions), best practice advice (one session), corticosteroid injection then progressive exercise, or corticosteroid injection then best practice advice. The primary outcome was the Shoulder Pain and Disability Index (SPADI) score over 12 months, analysed on an intention-to-treat basis (statistical significance set at 1%). The trial was registered with the International Standard Randomised Controlled Trial Register, ISRCTN16539266, and EuDRACT, 2016-002991-28.

FINDINGS

Between March 10, 2017, and May 2, 2019, we screened 2287 patients. 708 patients were randomly assigned to progressive exercise (n=174), best practice advice (n=174), corticosteroid injection then progressive exercise (n=182), or corticosteroid injection then best practice advice (n=178). Over 12 months, SPADI data were available for 166 (95%) patients in the progressive exercise group, 164 (94%) in the best practice advice group, 177 (97%) in the corticosteroid injection then progressive exercise group, and 175 (98%) in the corticosteroid injection then best practice advice group. We found no evidence of a difference in SPADI score between progressive exercise and best practice advice when analysed over 12 months (adjusted mean difference -0·66 [99% CI -4·52 to 3·20]). We also found no evidence of a difference between corticosteroid injection compared with no injection when analysed over 12 months (-1·11 [-4·47 to 2·26]). No serious adverse events were reported.

INTERPRETATION

Progressive exercise was not superior to a best practice advice session with a physiotherapist in improving shoulder pain and function. Subacromial corticosteroid injection provided no long-term benefit in patients with rotator cuff disorders.

Current concepts in the rehabilitation of rotator cuff related disorders

Rotator cuff related disorders (RCRD) are common. Exercise-based rehabilitation can improve outcomes, yet uncertainty exists regarding the characteristics of these exercises. This scoping review paper summarises the key characteristics of the exercise-based rehabilitation of rotator cuff related disorders (RCRD). An iterative search process was used to capture the breadth of current evidence and a narrative summary of the data was produced. 57 papers were included. Disagreement around terminology, diagnostic standards, and outcome measures limits the comparison of the data. Rehabilitation should utilise a biopsychosocial approach, be person-centred and foster self-efficacy. Biomedically framed beliefs can create barriers to rehabilitation. Pain drivers in RCRSD are unclear, as is the influence of pain during exercise on outcomes. Expectations and preferences around pain levels should be discussed to allow the co-creation of a programme that is tolerated and therefore engaged with. The optimal parameters of exercise-based rehabilitation remain unclear; however, programmes should be individualised and progressive, with a minimum duration of 12 weeks. Supervised or home-based exercises are equally effective. Following rotator cuff repair, rehabilitation should be milestone-driven and individualised; communication across the MDT is essential. For individuals with massive rotator cuff tears, the anterior deltoid programme is a useful starting point and should be supplemented by functional rehabilitation, exercises to optimise any remaining cuff and the rest of the kinetic chain. In conclusion, exercise-based rehabilitation improves outcomes for individuals with a range of RCRD. The optimal parameters of these exercises remain unclear. Variation exists across current physiotherapy practice and post-operative rehabilitation protocols, reflecting the wide-ranging spectrum of individuals presenting with RCRD. Clinicians should use their communication and rehabilitation expertise to plan an exercise-based program in conjunction with the individual with RCRSD, which is regularly reviewed and adjusted.

Shockwave therapy associated with progressive exercises in rotator cuff tendinopathy: a clinical trial protocol

The aim of the present study is to determine whether adding shockwave therapy (SWT) to a progressive exercise program improves shoulder pain and function in individuals with rotator cuff tendinopathy (RC tendinopathy). Ninety patients diagnosed with rotator cuff tendinopathy will be randomly allocated into two groups: active SWT plus a progressive exercise program or placebo SWT plus a progressive exercise program. Primary outcomes will be measured using the Constant-Murley Score function questionnaire and by assessing patient-reported pain intensity with the numerical pain rating scale. The secondary outcomes will be measured using the Global Perceived Effects Scale and Shoulder Pain and Disability Index. All the outcomes will be measured immediately after the end of treatment and at 3-month follow-up.

Rehabilitation following rotator cuff repair: A multi-centre pilot & feasibility randomised controlled trial (RaCeR)

OBJECTIVE

To evaluate the feasibility of a multi-centre randomised controlled trial to compare the clinical and cost-effectiveness of early patient-directed rehabilitation versus standard rehabilitation following surgical repair of the rotator cuff of the shoulder.

DESIGN

Two-arm, multi-centre pilot and feasibility randomised controlled trial.

SETTING

Five National Health Service hospitals in England.

PARTICIPANTS

Adults (n = 73) with non-traumatic rotator cuff tears scheduled for repair were recruited and randomly allocated remotely prior to surgery.

INTERVENTIONS

Early patient-directed rehabilitation (n = 37); advised to remove their sling as soon as able and move as symptoms allow. Standard rehabilitation (n = 36); sling immobilisation for four weeks.

MEASURES

(1) Randomisation of 20% or more eligible patients. (2) Difference in time out of sling of 40% or more between groups. (3) Follow-up greater than 70%.

RESULTS

73/185 (39%) potentially eligible patients were randomised. Twenty participants were withdrawn, 11 due to not receiving rotator cuff repair. The between-group difference in proportions of participants who exceeded the cut-off of 222.6 hours out of the sling was 50% (80% CI = 29%, 72%), with the early patient-directed rehabilitation group reporting greater time out of sling. 52/73 (71%) and 52/53 (98%) participants were followed-up at 12 weeks when withdrawals were included and excluded respectively. Eighteen full-thickness re-tears were reported (early patient-directed rehabilitation = 7, standard rehabilitation = 11). Five serious adverse events were reported.

CONCLUSION

A main randomised controlled trial is feasible but would require allocation of participants following surgery to counter the issue of withdrawal due to not receiving surgery.

Should Exercises be Painful or not? Effects on Clinical and Experimental Pain in Individuals with Shoulder Pain

Exercise can reduce pain, however the effect of painful versus non-painful exercises is uncertain. The primary aim of this randomized crossover study was to compare the effect of painful versus nonpainful isometric shoulder exercises on pain intensity after exercise in individuals with rotator cuff-related shoulder pain. Secondary exploratory aims were to describe the effects on pressure pain thresholds (PPTs), conditioned pain modulation (CPM) and muscle strength. On separate days, 35 individuals performed painful isometric shoulder exercises (external rotation; 20% above pain threshold), nonpainful isometric shoulder exercises (external rotation; 20% below pain threshold), and a rest condition, in randomised order. Shoulder pain intensity, PPTs, CPM, and external rotation strength were assessed before, immediately after and 45 minutes after conditions. No significant differences were observed between painful and nonpainful exercises. Visual analogue scale scores increased immediately after both painful and non-painful exercises compared with rest (P = .047, partial ƞ² = .07), but were similar to preexercise levels after 45 minutes. No changes in PPTs, CPM, or muscle strength after exercises compared with rest were observed. Painful and non-painful isometric exercises caused a moderate but short-lasting increase in shoulder pain in individuals with RCRSP. Isometric exercises had no effect on pain sensitivity and shoulder muscle strength or CPM. Perspective: This study evaluated for the first time in individuals with rotator cuff-related shoulder pain the effects of painful versus non-painful isometric exercises on different pain-related outcome measures. Both painful and non-painful isometric exercises caused a moderate but relatively short-lasting increase in shoulder pain in individuals with rotator cuff-related shoulder pain. Trial registration number: (ClinicalTrials.gov) NCT03675399.

Group-based exercise, individually supervised exercise and home-based exercise have similar clinical effects and cost-effectiveness in people with subacromial pain: a randomised trial

QUESTION

What are the relative effects of group-based exercise, individual exercise and home-based exercise on clinical outcomes and costs in patients with subacromial pain?

DESIGN

Multicentre, three-arm, randomised controlled trial with concealed allocation and intention-to-treat analysis.

PARTICIPANTS

A total of 208 patients referred to municipal rehabilitation for management of subacromial pain in six municipalities in the Central Denmark Region.

INTERVENTIONS

Patients were randomly allocated to group-based exercise rehabilitation (GE), individual exercise rehabilitation (IE) or home exercise rehabilitation (HE) for a period of 8 weeks.

OUTCOME MEASURES

The primary outcome measure was the shortened version of the Disabilities of the Arm, Shoulder and Hand questionnaire (Quick-DASH). The secondary outcome measures included the EQ-5D-5L index, pain intensity, fear avoidance, psychological wellbeing, and the participant's perception of improvement and satisfaction. Healthcare and productivity costs were extracted from national health and social registers.

RESULTS

There was no important between-group difference in Quick-DASH scores at 6 months: adjusted mean differences GE minus IE -2 (95% CI -9 to 5), GE minus HE -2 (95% CI -9 to 5) and HE minus IE 1 (95% CI -6 to 7). The estimates of the between-group differences were able to exclude any clinically important differences in the three regimens' effects on health benefits according to the EQ-5D-5L index and other secondary outcomes. The total average costs were highest for the IE group and lowest for the HE, but not statistically different across groups.

CONCLUSION

In people with subacromial pain, group-based exercise, individually supervised exercise and home-based supervised exercise regimens have similar benefits. The home exercise intervention was associated with lowest costs.

Exercise-Based Muscle Development Programmes and Their Effectiveness in the Functional Recovery of Rotator Cuff Tendinopathy: A Systematic Review

(1) Background: Rotator cuff (RC) tendinopathy causes pain and functional limitation of the shoulder. Physical exercises are effective therapies but there is no consensus on which exercise programme is the most appropriate. Objective: To analyze and compare the effectiveness of different intervention modalities-based exclusively on physical exercise muscle-development programs to improve shoulder pain and function in RC tendinopathy. (2) Methods: Systematic review (PRISMA) through a search in PubMed, WOS, PEDro, Cinahl, Scopus and Dialnet. The PEDro Scale and the Cochrane Risk of Bias analyzed the methodological quality. A pre-established table collected data on: patients, interventions, outcome measures and results. A narrative synthesis of the results was conducted. (3) Results: eight articles were selected (Cochrane: low risk of bias; PEDro: good quality). All assessed programs were effective. Only one study found statistically and clinically significant differences in favour of eccentric training. The exercises used were: eccentric/concentric/conventional, open/closed kinetic chain, with/without co-activation of glenohumeral muscle, with/without pain, and in clinic/at home. (4) Conclusions: All exercise programs were effective in RC tendinopathy, improving pain and shoulder function. No solid results were obtained when the interventions were compared due to their heterogeneity. Patients perception assessment tools were the most widely used. Amount of load applied should be considered.

French physiotherapy management of rotator cuff related shoulder pain: An observational study

BACKGROUND

Rotator cuff related shoulder pain (RCRSP) is a common and disabling cause of shoulder pain contributing to great socio-economic costs. Conservative management is recommended as first-line treatment, with studies performed in the United Kingdom, Belgium, the Netherlands and Australia finding practice generally consistent with guideline recommendations. Current French guidelines for management of RCRSP were published more than a decade ago, and it is unknown if French physiotherapists manage RCRSP in line with the current guideline recommendations. The aim of this survey is to evaluate if management delivered by French physiotherapists for RCRSP is in line with the current evidence.

METHODS

A cross-sectional online survey was conducted and disseminated through various social media platforms and a mailing list from December 2018 to March 2019.

RESULTS

Two hundred and six French physiotherapists completed the survey. The results demonstrated that the majority of physiotherapists provide care consistent with recommended guideline management, through the delivery of exercise and education. Ideology and specific parameters of treatment delivery, particularly exercise treatment, were highly variable among the cohort, but comparable to findings among physiotherapists in the United Kingdom, Belgium, the Netherlands and Australia.

CONCLUSION

French physiotherapists are broadly consistent with providing guideline recommended care of RCRSP; however, heterogeneity exists in the ideals and practice of specific treatment delivery, particularly within exercise management.

Effectiveness of conservative therapy in tendinopathy-related shoulder pain: A systematic review of randomized controlled trials

OBJECTIVE

Systematic review investigated efficacy of conservative therapy on pain and function in people with tendinopathy-related shoulder pain.

METHODS

Searches were conducted on six databases. All randomized controlled trials investigating efficacy of any conservative therapy on pain and function in people with tendinopathy-related shoulder pain were included. Estimates for each specific conservative therapy were presented as weighted mean differences (WMDs) or mean differences (MDs), with 95% confidence intervals (CIs). Quality of the evidence was assessed using GRADE.

RESULTS

Five randomized controlled trials were included. Extracorporeal shock-wave therapy (ESWT) was effective on pain at short-term (i.e., ≤3 months) when compared with control (WMD = -1.7 out of 101 points, -3.1 to -0.3; n = 158). Individual trials also suggested effects of non-steroidal anti-inflammatory drugs (NSAIDs) (-13.7 to -2.3; n = 365) and extracorporeal radial pressure pulse therapy (rESWT) (-40.0 to -27.0; n = 79). Laser therapy and ESWT were not effective on pain and function at short-term, respectively. No trials investigated medium- or long-term effects, and quality of the evidence ranged from low to very low quality.

CONCLUSIONS

Conservative therapies currently available for the rotator cuff management and biceps tendinopathy are not supported by low to very-low quality evidence.

Adherence to self-managed exercises for patients with persistent subacromial pain: the Ad-Shoulder feasibility study

BACKGROUND

Exercise is recommended for patients with subacromial pain. It has been suggested that good exercise adherence improves clinical outcomes. Despite this, little attention has been paid to the need for behavioural frameworks to enhance adherence to home exercise programmes for patients with subacromial pain.

METHODS

A feasibility study with pre-post design was used. Participants aged > 18 years, with subacromial pain, who had received conservative treatment during the past 6 months, were recruited. The Ad-Shoulder intervention consisted of 1-5 individual sessions provided over 3 months and was based on 5 self-management skills, which aimed to enhance the patients' self-efficacy and adherence to self-managed exercises. The primary objectives were assessed according to predefined progression criteria: (1) the recruitment rate (10 patients enrolled within 12 weeks), (2) follow-up rate (≥ 80% on all self-reported measures), (3) objective physical activity measures (≥ 80% of participants would contribute valid data at each time point), (4) adherence with the self-managed exercises (≥ 80% of the participants would adhere to ≥ 80% of the assigned home exercise programme), (5) fidelity of the delivery of the intervention (the therapists delivered the intervention according to the protocol) and (6) adverse events (< 30% would report adverse events (including mild)). The results were reported using descriptive statistics.

RESULTS

Eleven patients were recruited during 16 weeks. Ten patients completed the self-reported measures at baseline and week 12. Objective physical activity measures were successfully obtained for 100% (11/11) at baseline, 64% (7/11) at week six and 82% at week 12. Fifty-five percent (6/11) of the participants satisfactorily completed at least 80% of their home exercise programme. All sessions were delivered according to the protocol. None of the patients reported any adverse events.

CONCLUSIONS

Objective physical activity data measures at baseline and week 12, follow-up, the physiotherapists' fidelity to the intervention and adverse events met our pre-specified progression criteria. Recruitment and adherence to the self-managed exercise programme were both below the anticipated level. Further intervention development is necessary to understand whether adherence to the self-managed exercises could be enhanced and additional methods of recruitment would need to be considered, including additional recruitment sites, in any planning for a future main trial.

Tendinopathy

Tendinopathy describes a complex multifaceted pathology of the tendon, characterized by pain, decline in function and reduced exercise tolerance. The most common overuse tendinopathies involve the rotator cuff tendon, medial and lateral elbow epicondyles, patellar tendon, gluteal tendons and the Achilles tendon. The prominent histological and molecular features of tendinopathy include disorganization of collagen fibres, an increase in the microvasculature and sensory nerve innervation, dysregulated extracellular matrix homeostasis, increased immune cells and inflammatory mediators, and enhanced cellular apoptosis. Although diagnosis is mostly achieved based on clinical symptoms, in some cases, additional pain-provoking tests and imaging might be necessary. Management consists of different exercise and loading programmes, therapeutic modalities and surgical interventions; however, their effectiveness remains ambiguous. Future research should focus on elucidating the key functional pathways implicated in clinical disease and on improved rehabilitation protocols.

The inclusion of mobilisation with movement to a standard exercise programme for patients with rotator cuff related pain: a randomised, placebo-controlled protocol trial

Background

Rotator cuff related pain (RCRP) is one of the most common sources of musculoskeletal shoulder pain affecting the general population. Conservative treatment, in the form of exercise, is considered the first line approach, nonetheless, improvements seem to be modest. One therapeutic modality that might be an adjunct to the treatment of this condition is mobilisation with movement (MWM). MWM is a pain-free manual procedure that targets restricted and painful movements, commonly seen in patients with RCRP. The purpose of clinical trial is to determine whether MWM with exercise has benefits over sham MWM with exercise in RCRP.

Methods

A randomised, sham-controlled trial of 70 adults complaining of RCRP will compare the effects of MWM combined with exercise over sham MWM with exercise. Participants will be allocated to one of two groups: exercise and MWM (EG) or exercise and sham MWM (CG). Two weekly individual treatment sessions will be conducted over five weeks. All assessments will be performed by a blinded assessor. Primary outcome measures will be the shoulder pain and disability index (SPADI) and the numeric pain rating scale (NPRS), assessed at baseline, discharge and one-month follow-up. Secondary outcome measures will be active range of motion, self-efficacy and the global rating of change scale. The analyses will be conducted considering a statistically significant p-value ≤0.05. Normality will be assessed with the Kolmogorov-Smirnov test and homogeneity with the Levene’s test. For the primary outcome measures (SPADI and NPRS) and self-efficacy, a 2 × 3 ANOVA with treatment group (EG versus CG) and time (baseline, end of the treatment and follow-up) factors will be performed. Separate 2 × 2 ANOVA will be used for range of motion (baseline and end of the treatment). Global rating scale of change analysis will be conducted using descriptive statistics. Intention-to-treat analysis will be adopted.

Discussion

As there is a paucity of longitudinal studies investigating the use of MWM in patients with RCRP, this study will help to better understand its role together with a structured exercise programme.

PERCEIVED SELF-REPORT OF EFFORT DURING ROTATOR CUFF & SCAPULAR REHABILITATIVE EXERCISE IN PATIENTS AFTER SHOULDER SURGERY

Background

Rehabilitation following shoulder surgery involves the use of resistive exercise but dosing of these -exercises historically employs multiple sets of pre-determined repetitions and few reports document the perceived effort encountered by patients during these exercises for both elastic resistance and free-weights. The OMNI-Resistance Exercise Scale (OMNI-RES) has been tested and applied as a measure of perceived exertion (RPE) for resistive exercise but has not gained widespread acceptance as an optimal method for physical therapists to document RPE during rehabilitation of shoulder surgery.

Purpose

To generate descriptive values of RPE encountered during common shoulder exercises of varying resistance in patients following shoulder surgery as well as provide a comparative analysis between perceived exertion ratings of similar exercise movement patterns using elastic and traditional isotonic resistance.

Study Design

Descriptive Cross-sectional Cohort.

Methods

Sixty-six subjects (mean age 53.3 + 12.8 years) were included in this study following shoulder surgery (RC repair n=22, labral repair n=10, SA n=34). Perceived exertion using the OMNI-RES was recorded during performance of seven rotator cuff and scapular rehabilitation exercises at 6- and 12-weeks following surgery.

Results

Mean RPE using OMNI-RES in combined surgical groups ranged between 3.6 and 5.7 (mean = 4.50 + 2.1) across all seven exercises (scale 0 = very easy to 10 = extremely hard). From the external rotation (ER) exercise pair, paired t-tests revealed standing ER w/ Thera-band® (ERB) had a significantly higher OMNI-RES score versus sidelying ER w/ cuff weight (SLERW) (mean: 5.13 vs 4.41, p = 0.001) while the extension exercise pair consisting of standing shoulder extension w/ band (EXTB) and prone extension w/ cuff weight (PEXTW) showed no significant difference in OMNI-RES score (mean: 3.54, 3.67, p = 0.626).

Conclusion

Commonly prescribed resistance exercise in the rehabilitation following shoulder surgery show light-moderate ratings of perceived exertion at both 6 & 12 week post-operative timepoints across three surgical procedures.

Progressive exercise compared with best practice advice, with or without corticosteroid injection, for the treatment of rotator cuff disorders: statistical analysis plan for the Getting it Right: Addressing Shoulder Pain (GRASP) 2 × 2 factorial multicentre randomised controlled trial

BACKGROUND

The Getting it Right: Addressing Shoulder Pain (GRASP) trial assesses the clinical and cost-effectiveness of individually tailored, progressive exercise compared with best practice advice, with or without corticosteroid injection, in adults with a rotator cuff disorder. This article describes the statistical analysis plan for the GRASP randomised controlled trial.

METHODS/DESIGN

GRASP is a multicentre randomised controlled trial using a 2 × 2 factorial design. Adults aged ≥ 18 years with a new episode of shoulder pain related to a rotator cuff disorder, not currently receiving physiotherapy or being considered for surgery, are randomised (centralised computer-generated 1:1:1:1 allocation ratio) to one of four interventions: (1) progressive exercise (up to 6 physiotherapy sessions), (2) best practice advice (one physiotherapy session), (3) subacromial corticosteroid injection then progressive exercise and (4) subacromial corticosteroid injection then best practice advice. The primary outcome is the mean difference in Shoulder Pain and Disability Index (SPADI) total score over 12 months. Secondary outcomes are as follows: pain and function SPADI subdomains, health-related quality of life (EuroQol EQ-5D-5L), sleep disturbance, return to activity, global impression of change, health resource use, out-of-pocket expenses and work disability. Here, we describe in detail the following: sample size calculation, descriptive statistics of the primary and secondary outcomes, statistical models used for the analysis of the main outcomes, handling of missing data, planned sensitivity and subgroup analyses. This pre-specified statistical analysis plan was written and submitted without prior knowledge of the trial results.

DISCUSSION

Publication of the statistical analysis plan for the GRASP trial aims to reduce the risk of outcome reporting bias and increase transparency of the data analysis. Any deviations or changes to the current SAP will be described and justified in the final study report and any results publications.

Physical therapy for tendinopathy: An umbrella review of systematic reviews and meta-analyses

OBJECTIVE

To summarize evidence in the last decade regarding the efficacy of physical therapy interventions to treat tendinopathy, as a single disease entity, as determined in systematic reviews (SRs) and/or meta-analyses (MAs).

METHODS

Electronic search of PubMed, PEDro, and Scopus database was performed from year 2010 to January 2020. The methodological quality of the identified studies was assessed using the AMSTAR 2 tool. Studies scoring 9 points or higher were further analyzed using GRADE principles.

RESULTS

40 SRs and/or MAs were included in qualitative synthesis, whereas only 5 MAs were included in quantitative synthesis. Low-level laser therapy (LLLT) intervention showed a pooled improvement in pain reduction of 1.53 cm; 95% CI, [1.14, 1.91] (I² = 1.9%, p = 0.361) on visual analogue scale, and grip strength of 9.59 kg; 95% CI, [5.90, 13.27].

CONCLUSIONS

Moderate-quality evidence may support these following interventions: LLLT revealed a statistically and potentially clinically significant improvement in pain and function on the short-term. Extracorporeal shockwave therapy showed a statistically significant enhancement in pain and function at all follow-up durations; however, its clinical significance was undetermined. Eccentric exercise was supported by qualitative evidence only. Caution is advised when interpreting results due to possible pathological differences in tendinopathy at each region.

Optimising outcomes of exercise and corticosteroid injection in patients with subacromial pain (impingement) syndrome: a factorial randomised trial

Objectives

To compare the clinical effectiveness of (1) physiotherapist-led exercise versus an exercise leaflet, and (2) ultrasound-guided subacromial corticosteroid injection versus unguided injection for pain and function in subacromial pain (formerly impingement) syndrome (SAPS).

Methods

This was a single-blind 2×2 factorial randomised trial. Adults with SAPS were randomised equally to one of four treatment groups: (1) ultrasound-guided corticosteroid injection and physiotherapist-led exercise, (2) ultrasound-guided corticosteroid injection and an exercise leaflet, (3) unguided corticosteroid injection and physiotherapist-led exercise and (4) unguided corticosteroid injection and an exercise leaflet. The primary outcome was the Shoulder Pain and Disability Index (SPADI), collected at 6 weeks, 6 and 12 months and compared at 6 weeks for the injection interventions and 6 months for the exercise interventions by intention to treat.

Results

We recruited 256 participants (64 treatment per group). Response rates for the primary outcome were 94% at 6 weeks, 88% at 6 months and 80% at 12 months. Greater improvement in total SPADI score was seen with physiotherapist-led exercise than with the exercise leaflet at 6 months (adjusted mean difference −8.23; 95% CI −14.14 to -2.32). There were no significant differences between the injection groups at 6 weeks (−2.04; −7.29 to 3.22), 6 months (−2.36; −8.16 to 3.44) or 12 months (1.59; −5.54 to 8.72).

Conclusions

In patients with SAPS, physiotherapist-led exercise leads to greater improvements in pain and function than an exercise leaflet. Ultrasound guidance confers no additional benefit over unguided corticosteroid injection.

The Effectiveness of Ischemic Compression Technique on Pain and Function in Individuals With Shoulder Pain: A Systematic Review

OBJECTIVE

To systematically review current literature to determine the effectiveness of the ischemic compression (IC) technique on pain and function in individuals with shoulder pain.

METHODS

This review was conducted according to recommendations of Preferred Reporting Items for Systematic Reviews and Meta-Analyses and the Cochrane Collaboration for Systematic Reviews; a search was performed in the electronic databases PubMed, Cumulative Index to Nursing and Allied Health Literature, SPORTDiscus, Physiotherapy Evidence Database, and Web of Science. Randomized clinical trials and quasi-randomized clinical trials were included, and the methodological quality was evaluated through the Physiotherapy Evidence Database scale.

RESULTS

The search found 572 studies; of these, 71 were selected by title and, subsequently, 29 were selected through abstract analyses. After critical analyses, 5 studies were included. The methodological quality ranged from 4 (reasonable) to 9 (excellent) points. Pain was assessed by all studies using the visual analog scale, Global Perceived Effect scale, Numerical Rating Scale, pressure pain threshold, or Perceived Amelioration Numerical Scale. Function was evaluated by 3 studies through the Shoulder Pain and Disability Index; Neck Disability Index; American Shoulder and Elbow Surgeons Standardized Shoulder Assessment; and Disabilities of the Arm, Shoulder, and Hand questionnaires. The studies showed that the IC technique produces immediate and short-term positive effects for pain, and positive short-term effects for shoulder function in individuals with shoulder pain.

CONCLUSION

The IC technique seems to be beneficial for pain and shoulder function. However, caution is needed when considering this evidence owing to the limited quality of some studies, the few articles found, and the lack of standardization of the application parameters of the technique to facilitate its reproducibility.

Development of a physiotherapist-led exercise programme for traumatic tears of the rotator cuff for the SPeEDy study

OBJECTIVES

The SPeEDy study (Surgery vs. physiotherapist-led exercise for traumatic tears of the rotator cuff) is a two-arm, parallel group, pilot and feasibility randomised controlled trial aiming to evaluate the feasibility of a future main trial. In this paper, the development process and the resultant physiotherapist-led exercise programme used in the SPeEDy study is described.

METHODS

Thirteen physiotherapists and three patients met to discuss and develop the key principles that should underpin the exercise programme.

RESULTS

Taking in to account the current research evidence and incorporating expert clinical and patient opinion, the group developed an individualised, structured and progressive physiotherapist-led exercise programme based on the principle of self dosing. Exercise prescription within the programme is based on establishing the current functional capacity of the patient in relation to the most challenging shoulder movements and is supported over approximately six contact sessions across a 12-week period.

CONCLUSION

The SPeEDy study aims to recruit 76 participants across eight hospitals and will provide high quality evidence about the feasibility of a future main randomised controlled trial in a clinical area where there is a lack of evidence from randomised controlled trials to support clinical decision-making.

Effectiveness of progressive and resisted and non-progressive or non-resisted exercise in rotator cuff related shoulder pain: a systematic review and meta-analysis of randomized controlled trials

Objective:

Synthesize evidence regarding effectiveness of progressive and resisted or non-progressive and non-resisted exercise compared with placebo or no treatment, in rotator cuff related pain.

Data sources:

English articles, searched in Cochrane CENTRAL, MEDLINE, EMBASE and CINAHL databases up until May 19, 2020.

Methods:

Randomized controlled trials in people with rotator cuff related pain comparing either progressive and resisted exercise or non-progressive and non-resisted exercise, with placebo or no treatment were included. Data extracted independently by two authors. Risk of bias appraised with the Cochrane Collaboration tool.

Results:

Seven trials (468 participants) were included, four trials (271 participants) included progressive and resisted exercise and three trials (197 participants) included non-progressive or non-resisted exercise. There was uncertain clinical benefit for composite pain and function (15 point difference, 95% CI 9 to 21, 100-point scale) and pain outcomes at >6 weeks to 6 months with progressive and resisted exercise compared to placebo or no treatment (comparison 1). For non-progressive or non-resisted exercise there was no significant benefit for composite pain and function (4 point difference, 95% CI −2 to 9, 100-point scale) and pain outcomes at >6 weeks to 6 months compared to placebo or no treatment (comparison 2). Adverse events were seldom reported and mild.

Conclusions:

There is uncertain clinical benefit for all outcomes with progressive and resisted exercise and no significant benefit with non-progressive and non-resisted exercise, versus no treatment or placebo at >6 weeks to 6 months. Findings are low certainty and should be interpreted with caution.

Getting more from standard rotator cuff strengthening exercises

BACKGROUND

A simple modification to standard rotator cuff exercises using an additional resistance band around the scapula has been recommended in the clinical setting, postulated to encourage activation of the posterior scapular stabilisers and increase rotator cuff activation. The aim of this clinical laboratory study was to compare scapular and rotator cuff muscle activation between standard and modified exercises.

METHODS

Electromyographic data were collected from 10 healthy adults via surface and intramuscular electrodes from the scapular and rotator cuff muscles. Internal and external rotation exercises of the shoulder with the arm abducted to 0°, 45° and 90° were performed using one handheld resistance band (standard) or two bands with the additional band applied to the scapula (modified).

RESULTS

Activation of the trapezii and rhomboid muscles during the modified exercises at 0° and 45° of abduction was significantly greater when compared to the standard exercises (P < 0.05). No significant differences were found in rotator cuff muscle activation.

DISCUSSION

Applying resistance to the posterior scapula increases activation of some scapular stabilising muscles particularly in lower ranges of abduction. This study provides preliminary evidence that this simple modification can elicit greater scapular muscle activity, potentially producing enhanced exercise outcomes with minimal additional effort.

Physiotherapists deliver management broadly consistent with recommended practice in rotator cuff tendinopathy: An observational study

BACKGROUND

Rotator cuff tendinopathy is a common and disabling cause of shoulder pain. While conservative treatment is recommended as initial management, recent findings suggest that general practitioners and rheumatologists do not consistently align with recommended care. This study aimed to survey Australian physiotherapists to explore the extent to which recommended management is being applied.

METHODS

A cross-sectional online survey.

RESULTS

Five hundred and two Australian physiotherapists completed the survey. Results demonstrated the majority of physiotherapists provide conservative management consistent with guideline recommendations, through delivery of exercise and education, comparable to management by physiotherapists in the United Kingdom, Belgium and the Netherlands. Parameters and construction of exercise treatment programs were highly variable within the cohort, qualitative analysis highlighting varied reasoning underpinning these management decisions.

CONCLUSIONS

Australian physiotherapists are broadly consistent with providing recommended management, however heterogeneity exists in the methods and parameters of treatment delivery.

The Effectiveness of an Upper Extremity Neuromuscular Training Program on the Shoulder Function of Military Members With a Rotator Cuff Tendinopathy: A Pilot Randomized Controlled Trial

INTRODUCTION

Shoulder pain, a leading reason to consult a physician or physiotherapist, continues to be a challenge to rehabilitate, particularly with a military population. A rotator cuff (RC) tendinopathy, the most important source of shoulder pain, is one of the leading reasons for sick leave or a discharge from active military service. Research encourages the use of exercise prescription for the management of a RC tendinopathy, however the ideal method of delivery (group setting versus one-on-one) remains uncertain. The purpose of this single-blind (evaluator) pilot randomized clinical trial was to compare two 6-week rehabilitation programs, a newly developed group-supervised neuromuscular training program and usual one-on-one physiotherapy care, on the pain and symptoms of Canadian soldiers affected by a RC tendinopathy.

MATERIALS AND METHODS

Thirty-one soldiers with the Canadian Armed Forces were randomly assigned to (1) a group-supervised neuromuscular training program (UPEx-NTP) or; (2) one-on-one usual physiotherapy care (UPC). The primary outcome was the Disability of Arm, Hand and Shoulder (DASH) questionnaire. Secondary outcomes included the Western Ontario Rotator Cuff (WORC) Index, pain levels at rest, and maximum isometric voluntary contractions (MIVC) of the abductors and external (lateral) rotators of the affected shoulder. Both were assessed at baseline (T0), 6 (T6) and 12 (T12) weeks. Analysis included two-way repeated measures of variance for intention-to-treat (ITT) and per-protocol analyses.

RESULTS

Eighty military members with a RC tendinopathy were contacted, resulting in 31 participants who were randomized for their active intervention, in the UPEx-NTP or UPC, respectively. No significant group (p ≥ 0.16) or group × time interactions (p ≥ 0.11) were found for either ITT or per-protocol analyses. A statistically significant time effect (p < 0.001) was established for the DASH and WORC, showing that both groups improved over time.

CONCLUSIONS

Our preliminary data demonstrates that both rehabilitation approaches, grounded in active exercises, were not statistically different from each other, and derived similar benefits over time for a military population. This suggests that a group intervention for a RC tendinopathy has potential to be just as effective as a one-on-one approach for a military population, an interesting avenue for an active working population. Larger sample sizes and further investigation are warranted regarding the cost and clinical resource benefits of a supervised group approach.
