Abstract
PURPOSE To compare the short and medium-term effects of physiotherapy plus corticosteroid injection (combined) with physiotherapy alone on pain intensity, disability, Quality of Life (QoL), and treatment effectiveness in patients with Subacromial Pain Syndrome (SAPS). METHODS In this double-blind, parallel Randomized Controlled Trial (RCT), 50 patients with SAPS were randomly assigned into combined (N = 25, a single injection 3-6 days before physiotherapy) and physiotherapy alone group (N = 25). Pain, disability, QoL, and treatment-effectiveness were measured at pre-intervention, post-intervention, and 3 and 6-month follow-up with Visual Analog Scale (VAS), Shortened Disability of the Arm, Shoulder, and Hand (Quick-DASH), Shoulder Pain and Disability Index (SPADI) (primary outcome measure), Western Ontario Rotator Cuff (WORC), and Global Rating of Change (GRC) respectively. A 2 × 4 (group × time) mixed model analysis of variance (ANOVA) was applied for analysis. RESULTS The ANOVA revealed statistically significant group-in-time interaction for all outcome measures (p-value < 0.05). The independent t-test showed more effectiveness in the combined group at medium-term, as the mean scores of almost all outcome measures were substantially lesser (p < 0.01). Moreover, in short-time, despite a greater number of patients stating "completely recovered" in the combined group, there was no statistically significant difference between groups. CONCLUSIONS Effects of physiotherapy plus corticosteroid injection could be more long-lasting than physiotherapy alone in improving pain intensity, disability, QoL, and treatment effectiveness in patients with SAPS. TRIAL REGISTRATION NUMBER IRCT20201010048980N1.IMPLICATIONS FOR REHABILITATIONShoulder pain is common, persistent, and predominantly results from subacromial pain syndrome (SAPS).Physiotherapy and corticosteroid injections are effective interventions for this condition.Comprehensive physiotherapy alone can be as effective as corticosteroid injection combined with physiotherapy in the short term.A combined approach versus physiotherapy alone may have more medium-term effects on SAPS patients' pain, disability, quality of life, and treatment effectiveness.

Abstract
OBJECTIVE To describe and examine potential predictors of changes in pain and disability in patients with shoulder pain who have completed 3 months of digitally delivered treatment comprising exercise and patient education. DESIGN Retrospective cohort study (clinicaltrials.org Nr: NCT05402514). SUBJECTS Patients with shoulder pain who completed treatment (n = 682). METHODS Primary outcome was change in shoulder pain (numerical rating scale 0-10; minimal clinical important change: at least 2 points). Pain and disability were reported on the Shoulder Pain and Disability Index. Changes in outcomes were analysed with paired sample t-tests. Association with potential predictors (sex, age, education, body mass index, physical activity, symptom duration, baseline pain/function, and treatment adherence) were explored with linear regression models Results: Statistically significant improvements were found for all treatment outcomes. Minimal clinically important change in pain was reached by 54.5% (n = 372). Higher baseline level of symptoms, short symptom duration, and high treatment adherence were associated with greater changes. CONCLUSION Patients with shoulder pain reported significant reductions in pain and disability following treatment, but the clinical relevance of the improvements has not been confirmed. Satisfactory treatment adherence, higher baseline pain and shorter symptom duration predicted larger improvements. A control group is needed to evaluate the actual effect of the treatment.

Abstract
BACKGROUND Exercise is considered to be both essential and at the forefront of the management of rotator cuff-related shoulder pain (RCRSP). Despite this, many fail to substantially improve with exercise-based treatment. Hence, expanding the current knowledge about the possible mechanisms of exercise for RCRSP is critical. OBJECTIVE To synthesise the range of mechanisms proposed for exercise in people with RCRSP. DESIGN Scoping review METHODS: A systematic search of the Physiotherapy Evidence Database (PEDro) was conducted from inception to July 3, 2022. Two reviewers conducted the search and screening process and one reviewer extracted the data from each study. Randomised clinical trials using exercise for the management of RCRSP of any duration were included. The PEDro search terms used were "fitness training", "strength training", "stretching, mobilisation, manipulation, massage", "upper arm, shoulder, or shoulder girdle", "pain", and "musculoskeletal". Data were analysed using quantitative and qualitative approaches. RESULTS 626 studies were identified and 110 were included in the review. Thirty-two unique mechanisms of exercise were suggested by clinical trialists, from which 4 themes emerged: 1) neuromuscular 2) tissue factors 3) neuro-endocrine-immune 4) psychological. Neuromuscular mechanisms were proposed most often (n = 156, 77%). Overall, biomedical mechanisms of exercise were proposed in 95% of cases. CONCLUSIONS The causal explanation for the beneficial effect of exercise for RCRSP in clinical research is dominated by biomedical mechanisms, despite a lack of supporting evidence. Future research should consider testing the mechanisms identified in this review using mediation analysis to progress knowledge on how exercise might work for RCRSP.

Abstract
Introduction Shoulder impingement syndrome (SIS) is one of the common problems which lead to shoulder disabilities. This condition has been described as impingement to the rotator cuff by the anterior third of the acromion process and has been classified into three stages. Treatment option varies depending on the grade of the disease. Arthroscopic subacromial decompression (ASAD) has become more popular in recent years and has shown to have a good outcome. The purpose of this study is to evaluate the outcomes following ASAD in terms of the functional, clinical, and radiological parameters in treating SIS in the ageing population in Kuantan, Pahang, Malaysia. Materials and methods This was an observational study looking at the outcomes of patients with stage 2 and stage 3 (partial cuff tear) impingement syndrome who underwent ASAD in Hospital Tengku Ampuan Afzan and International Islamic University Malaysia Medical Centre from May 2018 to June 2019. The functional outcomes were evaluated using American Shoulder and Elbow Surgeons (ASES) score taken at pre-operative, six weeks, three months, and six months post-operation. Clinical outcomes were evaluated using Constant score (CS) taken at six months post-operation. Radiological outcomes were measured by comparing acromiohumeral distance pre- and post-operation on anteroposterior (AP) view radiograph of the affected shoulder. Results A total of 28 patients were selected for the study. On functional outcome, there was a significant effect of time on the ASES scoring system (p-value <0.05) from pre-operative to six months post-operation. On clinical outcome, the CS at six months showed 13 patients have excellent scores, 10 have good, and five have fair scores. There was a statistically significant difference in mean values of all categories (p-value <0.05). In terms of the radiological outcome, this study observed a significant increase in patients’ subacromial space on X-ray from the pre-operative and post-operative treatment stages. In this study, we also observed that there was no significant difference in outcomes between partial and intact rotator cuff (RC) tears at six-month post-operation. Conclusion In this study, ASAD was found to be a beneficial intervention in the treatment of patients with shoulder impingement evidenced by the significant outcomes in terms of functional, clinical, and radiological parameters.

Abstract
BACKGROUND A strong recommendation against subacromial decompression surgery was issued in 2019. This leaves nonoperative care as the only treatment option, but recent studies suggest that the dose of strengthening exercise is not sufficient in current nonoperative care. At this point, it is unknown if adding more strengthening to current nonoperative care is of clinical value. PURPOSE To assess the effectiveness of adding a large dose of shoulder strengthening to current nonoperative care for subacromial impingement compared with usual care alone. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS In this double-blinded, pragmatic randomized controlled trial, we randomly allocated 200 consecutive patients referred to orthopaedic shoulder specialist care for long-standing shoulder pain (>3 months), aged 18 to 65 years and diagnosed with subacromial impingement using validated criteria, to the intervention group (IG) or control group (CG). Outcome assessors were blinded, and participants were blinded to the study hypothesis as well as to the treatment method in the other group. The CG received usual nonoperative care; the IG underwent the same plus an add-on intervention designed to at least double the total dose of shoulder strengthening. The primary outcome was the Shoulder Pain and Disability Index (SPADI; 0-100) at 4-month follow-up, with 10 points defined as the minimal clinically important difference. Secondary outcomes included shoulder strength, range of motion, health-related quality of life, and the Patient Acceptable Symptom State (PASS). RESULTS Intention-to-treat and per-protocol analyses showed no significant or clinically relevant between-group differences for any outcome. From baseline to 4-month follow-up, SPADI scores improved in both groups (intention-to-treat analysis; IG, -22.1 points; CG, -22.7 points; between-group mean difference, 0.6 points [95% CI, -5.5 to 6.6]). At 4 months after randomization, only 54% of the IG and 48% of the CG (P = .4127) reached the PASS. No serious adverse events were reported. CONCLUSION Adding a large dose of shoulder strengthening to current nonoperative care for patients with subacromial impingement did not result in superior shoulder-specific patient-reported outcomes. Moreover, approximately half of all randomized patients did not achieve the PASS after 4 months of nonoperative care, leaving many of these patients with unacceptable symptoms. This study showed that adding more exercise is not a viable solution to this problem. REGISTRATION NCT02747251 (ClinicalTrials.gov identifier).

Abstract
OBJECTIVE The primary aim was to describe the variability within clinical presentation of patients with subacromial pain in primary care, secondly to investigate associations between clinical presentation and self-reported pain intensity, shoulder function, level of anxiety and depression, and health-related quality of life. DESIGN AND SETTING A cross-sectional study based on data from two clinical studies in primary care, one randomized controlled trial and one implementation study. Three components: active range of motion (AROM), rotator cuff function and scapular kinematics were analyzed to describe variability within clinical presentation and patient-reported measurements were used to investigate the impact on daily life. PARTICIPANTS Patients aged 30-67 years, describing pain for more than two weeks, with positive signs for a minimum of three out of the following five clinical tests: impingement sign according to Neer, impingement test according to Hawkins-Kennedy, Pattes maneuver, Jobe's test, and painful arc. RESULTS Among the 164 patients included, 24% displayed dysfunction in one, 50% two and 24% in all three components. Limited AROM was seen in 46%, rotator cuff dysfunction in 91% and scapular dyskinesia in 57% of the patients. CONCLUSIONS These results reveal a heterogeneity among primary care patients with subacromial pain confirming a large variability regarding the components AROM, rotator cuff function and scapular kinematics. All three components appear unique (not significantly correlated) where a rotator cuff dysfunction is very frequent while limited AROM and scapular dyskinesia are more inconsistent. There are significant, but rather weak, associations between clinical presentation and impact on daily life.

Abstract
BACKGROUND Strength deficits are often reported in people with rotator cuff related shoulder pain. However, these have mainly been tested in athletic populations and pain interference with testing has not been considered. OBJECTIVES To examine strength without pain interference in non-athletic people with rotator cuff related shoulder pain and its association with pain intensity and disability. DESIGN Cross-sectional study. METHODS Sixty-seven participants with rotator cuff related shoulder pain were assessed for isometric strength of shoulder external rotator and internal rotator muscles without pain interference with a hand-held dynamometer. Strength was normalized (%body weight). Differences in external and internal rotation strength and external:internal rotator strength ratio between symptomatic and asymptomatic sides were examined (Independent t-tests, Wilcoxon rank sum tests). Spearman's rank correlation coefficients were used to examine associations between strength and pain and disability levels. RESULTS There was no significant difference in internal rotator strength normalized to body weight between symptomatic and asymptomatic sides. There was a significant difference in external rotator strength normalized to body weight (p < .001) and external:internal ratio (p < .001) between sides. No significant correlations were found between strength and pain or disability levels. CONCLUSION Non-athletic people with rotator cuff related shoulder pain had external rotator strength deficits without pain interference during strength testing, which were not associated with pain and disability levels.

Effects of a Traditional versus an Alternative Strengthening Exercise Program on Shoulder Pain, Function and Physical Performance in Individuals with Subacromial Shoulder Pain: A Randomized Controlled Trial.

Abstract
A manual shoulder-training device may represent an alternative training device to improve symptoms and function in patients with subacromial shoulder pain by strengthening the external rotators. Thus, we examined the effects of a traditional versus an alternative strengthening exercise program on shoulder pain/function and physical performance in individuals with subacromial shoulder pain. Fifty-six adults with subacromial shoulder pain were randomly assigned to a passive control group (CON; n = 20), a traditional training group (TRA; n = 19), or an alternative training group (ALT; n = 17). Both training groups conducted a progressive home-based strengthening exercise program for the external rotators for eight weeks using elastic bands only (TRA group) or in combination with the shoulder-training device (Schulterhilfe®) (ALT group). Pre- and post-training assessment included measures of shoulder pain/function (i.e., shoulder pain and disability index (SPADI)) and physical performance (i.e., shoulder flexibility, maximal isometric strength, and strength endurance). We found significant test × group interactions in most of the investigated variables. Post hoc analyses showed significant training-related improvements for proxies of shoulder pain/function, shoulder flexibility, maximal isometric strength, and strength endurance in favor of the ALT and TRA group in comparison to the CON group. Further, larger and more frequent effects were found for the ALT compared to the TRA group. Measures of shoulder pain/function and physical performance can be significantly improved by both training regimens in individuals with subacromial shoulder pain. However, strength training using elastic bands with the manual shoulder device (ALT group) as compared to elastic bands (TRA group) only was more effective and may thus be a recommendable alternative in order to mitigate subacromial shoulder pain.

Abstract
PURPOSE The psychometric properties of the shoulder pain and disability index (SPADI) have been extensively evaluated using classical test theory, but very few studies have applied Rasch analysis. The purpose of this study was to validate the Danish version using Rasch analysis. METHODS Responses to the SPADI from 229 patients (48% female, mean age 54.5) were included in the Rasch analysis. Overall fit, individual item fit, local response dependence, dimensionality, targeting, reliability, and differential item functioning (DIF) were examined. RESULTS After iterative analyses, good fit to the Rasch model was observed, with acceptable targeting and uni-dimensionality. SPADI should be reported as two separate subscales: Pain and Functional Disability. The pain subscale initially demonstrated misfit due to local dependence and DIF, but a log linear Rasch model showed good fit to the Rasch model with acceptable targeting and uni-dimensionality. A six-item version of the disability subscale exhibited adequate fit in the Danish version. The same items were also found to fit the Rasch model in the English version. CONCLUSIONS The measurement properties of the Danish SPADI are similar to those of the English version. SPADI should be reported as two separate subscales. For the pain subscale, DIF with respect to age was disclosed, but the impact was small. The eight-item disability subscale did not fit the Rasch model. A six-item version of the disability subscale exhibited adequate fit in the Danish version. The same items were also found to fit the Rasch model in the English version.
