Effectiveness of a Posterior Shoulder Stretching Program on University-Level Overhead Athletes: Randomized Controlled Trial.

OBJECTIVE: To determine whether a posterior shoulder stretch was effective in increasing internal rotation (IR) and horizontal adduction (HAd) range of motion (ROM) in overhead athletes identified as having reduced mobility. DESIGN: Randomized controlled trial (parallel design). SETTING: University-based sports medicine clinic. PARTICIPANTS: Thirty-seven university-level athletes in volleyball, swimming, and tennis, with IR ROM deficits ≥15°, were randomized into intervention or control groups. No subjects withdrew or were lost to follow-up. INTERVENTION: The intervention group performed the "sleeper stretch" daily for 8 weeks, whereas the control group performed usual activities. MAIN OUTCOME MEASURES: Independent t tests determined whether IR and HAd ROM differences between groups were significant at 8 weeks and 2-way repeated-measures analysis of variance tests measured the rate of shoulder ROM change. Subject-reported shoulder pain and function were obtained at each evaluation. RESULTS: Significant differences were found between the intervention and control groups' IR and HAd ROM at 8 weeks (P < 0.001 and P = 0.003, respectively) compared with baseline (zero weeks) (P = 0.19 and P = 0.82, respectively). Significant improvements in IR were detected in the intervention group at 4 weeks (P < 0.001), whereas HAd demonstrated significant changes only at 8 weeks (P = 0.003). Reported shoulder function (P = 0.002) was different between study groups at 8 weeks. CONCLUSION: Overhead, university-level athletes with an IR deficit ≥15° significantly increased their IR and HAd ROM after performing a posterior shoulder stretch for 8 weeks. CLINICAL RELEVANCE: Effective management of posterior shoulder tightness through stretching may reduce the incidence of shoulder pathology in overhead athletes.

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.

Rehabilitation after arthroscopic Bankart repair: a systematic scoping review identifying important evidence gaps.

BACKGROUND: Evidence to develop best rehabilitation practices after Arthroscopic Bankart Repair (ABR) is lacking, leading to heterogeneity in rehabilitation approaches. OBJECTIVES: This systematic scoping review investigated current evidence for rehabilitation and associated outcomes following ABR, including rehabilitation parameters, evaluative approaches (outcomes/outcome measures, follow-up timing/duration). DATA SOURCES: A systematic search was performed of CINAHL, MEDLINE, and Embase databases in May 2019. STUDY SELECTION: Prospective studies detailing rehabilitation protocols following ABR reporting at least one postoperative assessment within 1 year of surgery (to measure impact of rehabilitation) were included. DATA EXTRACTION AND SYNTHESIS: Two blinded reviewers independently selected studies using standardized criteria and extracted study characteristics and outcomes of interest. Quality of evidence was assessed using Joanna Brigg's quality assessment tool. A narrative analysis was conducted and evidence gaps were identified. RESULTS: Nine studies evaluating 11 rehabilitation protocols with a total of 384 participants were included. Considerable variability was seen in rehabilitation protocols and evaluation parameters. Return to sports/activity was frequently measured, but not well-defined. Strengthening was an important component of rehabilitation protocols, but rarely reported as an outcome. Follow-up was variable, with 4 studies ending follow-up before 24-months postoperatively. Overall, patient outcomes improved postoperatively. CONCLUSIONS: There is a paucity of evidence investigating the impact of rehabilitation approaches following ABR. Although patient outcomes improve after ABR, selected outcomes/measures are highly variable with limited evidence on those important to measure rehabilitation success, particularly strength and return to activity. Identified evidence gaps should be addressed in future research.

Evaluating the Uptake and Acceptability of Standardized Postoperative Rehabilitation Guidelines Using an Online Knowledge Translation Approach.

BACKGROUND: Providing physical therapists with evidence-based and consensus-derived guidelines to manage postoperative shoulder patients is essential; these guidelines should be readily available and provide clinically applicable information. Knowledge translation (KT) initiatives that encourage interaction between clinicians and researchers, that have multifaceted components and use a variety of strategies, can significantly change practice. OBJECTIVE: The objective of this study was to determine the uptake and acceptability of standardized postoperative shoulder guidelines with an accompanying online KT resource through evaluation of website analytics and a quantitative survey. DESIGN: A multi-pronged approach was used to assess uptake and acceptability of the guidelines and online KT resource. METHODS: Website analytics of usage and geographical location of users was measured as were physical therapist survey responses. RESULTS: Website analytics revealed that 5406 individuals used the online resource between October 2012 and September 2013 with the average visit lasting 8 minutes; only 47% of users were within the guideline developers' surgical referral region. Physical therapists who used the new shoulder guidelines were very satisfied or satisfied (96%) with the guidelines, reporting they promoted patient-specific clinical decision-making extremely or very well (68%). They viewed the online KT resource positively, with 79% rating it as "very useful" or "quite useful." Physical therapists from regions beyond those expected to use the new shoulder guidelines were also aware of the website and also rated it as very useful. LIMITATIONS: The survey sample was relatively small and did not directly assess patient outcomes. CONCLUSIONS: An online KT web resource developed in conjunction with standardized postoperative shoulder guidelines was perceived as useful based on website analytics and survey responses. Active KT strategies such as this can improve uptake and dissemination of best practice in physical therapy.

Can clinical assessment differentiate partial thickness rotator cuff tears from full thickness rotator cuff tears? A secondary analysis.

Purpose: Shoulder pain causes significant disability, with rotator cuff disease as a common diagnosis. Differentially diagnosing partial tears of the rotator cuff tendons is difficult despite use of imaging and clinical examination. Our objective was to determine if a clinical assessment framework could discriminate between patients with partial and full thickness tears.Materials and Methods: Pre-operative baseline data from two randomized controlled trials of 452 adult patients awaiting rotator cuff repair were analyzed in this secondary analysis. Nineteen items from a pre-defined clinical assessment framework were investigated for association with the outcome of surgically confirmed partial or full thickness tear. Logistic regression tested independent associations and multivariable models were developed to create the most parsimonious model.Results: Thirty-two participants (7%) had partial thickness tears. Constant Power Score was the sole item associated with partial thickness tears (OR 1.07, 95% CI 1.02-1.12). Traumatic mechanism of injury trended toward significance (OR 2.17, 95% CI 1.06-4.48).Conclusions: Greater abduction strength (i.e., Constant Power Score) was associated with partial thickness tears. Other clinical assessment items did not differentiate between partial and full tears. Our results add to the growing body of research showing most clinical findings are not associated with a diagnosis in rotator cuff disease.Implications for RehabilitationGreater shoulder abduction strength (as measured with the Constant Power Score) was associated with partial thickness rotator cuff tears.Most findings within our clinical assessment framework did not distinguish between partial thickness and full thickness rotator cuff tears and thus, did not contribute to a differential pathoanatomical diagnosis.Since structural integrity of the rotator cuff and patient presentation show poor association, and rehabilitation intervention is often impairment-based, pathoanatomical diagnosis may not adequately direct non-surgical treatment. Including movement-based diagnoses or treatment classification systems in evaluation of rotator cuff disease may improve selection of appropriate conservative treatment.
