Which Multimodal Physiotherapy Treatment Is the Most Effective in People with Shoulder Pain? A Systematic Review and Meta-Analyses. Healthcare (Basel) 2024; 12:1234. [PMID: 38921347 PMCID: PMC11203989 DOI: 10.3390/healthcare12121234] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2024] [Revised: 06/09/2024] [Accepted: 06/14/2024] [Indexed: 06/27/2024] Open
Abstract
The study aimed to determine if combined physiotherapy treatments offer additional benefits over exercise-only programs for shoulder pain and to identify the most effective combined treatment. A systematic review, registered in PROSPERO (CRD42023417709), and meta-analyses were conducted. Quality analysis was performed using the PEDro scale on randomized clinical trials published from 2018 to 2023. Twenty articles met the inclusion criteria. The most commonly used combination was exercise plus manual therapy, without being statistically superior to exercise alone. The meta-analysis indicated that combining exercise with low-level laser therapy (mean difference of -1.06, 95% CI: -1.51 to -0.60) and high-intensity laser therapy (mean difference of -0.53, 95% CI: -1.12 to 0.06) resulted in the greatest reduction in SPADI scores. Adding manual therapy provided limited additional benefit (mean difference of -0.24, 95% CI: -0.74 to 0.27). Progressive exercise with advice or telerehabilitation yielded modest improvements. The multimodal meta-analysis for DASH scores showed significant improvement (mean difference of -1.06, 95% CI: -1.51 to -0.60). In conclusion, therapeutic exercise is the cornerstone of shoulder pain treatment, with the addition of laser therapy showing substantial benefits. Manual therapy and educational interventions offer some benefits but are not consistently superior. More rigorous studies are needed.

Abstract
Background The objective was to identify exercise therapy dosing parameters for subacromial pain syndrome (SAPS) associated with improved pain and function outcomes (via effect sizes) and determine the extent of exercise intervention reproducibility. Methods An electronic search of PubMed/MEDLINE, Cumulative Index to Nursing and Allied Health Literature, EMBASE, Cochrane Database of Systematic Reviews, and SportDiscus identified studies that used exercise therapy exclusively to treat SAPS. Exercise therapy dosing parameters were extracted and within-group effect sizes were calculated for all pain and functional outcomes. Template for Intervention Description and Replication and Consensus on Exercise Reporting were used to record intervention reporting. The risk of bias and Grading of Recommendations, Assessment, Development, and Evaluation were assessed by two reviewers. Results Twenty-one trials with 674 subjects were included. Effect sizes for pain and function were large in 18 studies, medium in six studies, and small or no effect in four studies, despite the type of supervision. With moderate certainty, effect sizes of pain and function were not influenced by exercise therapy dosing parameters. Intervention reporting was generally poor. Discussion Exercise therapy for SAPS was associated with large effect sizes for improvement in pain and function but optimal exercise therapy dosing parameters could not be identified. Strong recommendations conditionally suggest treating SAPS with a variety of exercise therapy dosing parameters.

Abstract
Objectives Current evidence on the clinical effectiveness about the different types of exercises in the subacromial impingement syndrome (SIS) remains controversial. This study aims to compare the short-term (at 5 weeks) effects of a specific exercise programme with a general exercise programme on shoulder function in adults with SIS. Methods In total, 52 adults with SIS were randomly allocated to 5 weeks to perform specific exercises (experimental group, n=26) or general exercises (control group, n=26). The primary outcome was change in shoulder function, it was assessed using the Shoulder Pain and Disability Index (SPADI) from baseline to 5 weeks. Secondary end points included changes in upper limb function (Disabilities of the Arm, Shoulder, and Hand (DASH) Questionnaire), pain intensity (Visual Analog Scale (VAS)) and kinesiophobia (Tampa Scale of Kinesiophobia (TSK)). Results All participants completed the trial. The between-group differences at 5 weeks were: SPADI, 13.5 points (95% CI: 4.3 to 15.6; ƞ2=0.22; p=0.001); DASH, 10.1 points (95% CI: 5.6 to 15.2; ƞ2=0.27; p<0.001); VAS at rest, 0.2 cm (95% CI: 0.1 to 0.3; ƞ2=0.07; p=0.553); VAS on movement, 1.7 cm (95% CI: 0.9 to 2.2; ƞ2=0.24; p<0.001); and TSK, 16.3 points (95% CI: 13.2 to 15.3; ƞ2=0.33; p<0.001). All differences favoured the experimental group and effect sizes were medium to large for most outcomes. Mediation analyses showed that the effect of the specific exercises on shoulder function was mediated by kinesiophobia (β=2.800; 95% CI: 1.063 to 4.907) and pain on movement (β= -0.690; 95% CI: -1.176 to -0.271). Conclusion In adults with SIS, specific exercises may have a larger effect than general exercises. However, most differences did not reach the minimum threshold to be considered clinically important and the evidence to support exercise as standard treatment warrant further study.

Arthroscopic release of the pectoralis minor tendon as an adjunct to acromioplasty in the treatment of subacromial syndrome associated with scapular dyskinesia. Orthop Traumatol Surg Res 2022; 108:103211. [PMID: 35077896 DOI: 10.1016/j.otsr.2022.103211] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Revised: 06/10/2021] [Accepted: 06/18/2021] [Indexed: 02/03/2023]
Abstract
INTRODUCTION One of the causes of scapular dyskinesia is the retraction of the pectoralis minor muscle. It can be the cause of shoulder pain associated with increased anterior tilt and internal rotation of the shoulder. HYPOTHESIS Arthroscopic release of the pectoralis minor tendon is effective for shoulder pain, linked to a correction of dyskinesia, resulting in the early disappearance of scapulalgia. PATIENTS AND METHODS This was a retrospective, monocentric, single-surgeon study on a continuous series of patients with symptomatic shoulder pain, related to subacromial impingement associated with scapular dyskinesia. The series underwent arthroscopic tenotomies of the pectoralis minor between January 2015 and September 2018. Fifty-eight releases were performed to 57 patients (22 males, 35 females), with a mean age of 51.4 years (29-66 years). In all cases, they presented pain on palpation of the upper bundle of the trapezius muscle, and on palpation of the coracoid insertion of the pectoralis minor. RESULTS Preoperatively, there were 30 cases of stage 1 scapular dyskinesia and 28 cases of stage 2, with a scapular index measured at 53.84 (41.66-65.78), while the constant score was 41.46 (19-59). Upper trapezius pain was present in 87.7% of cases. The 57 patients were clinically assessed, with a mean follow-up of 8.9 months (6-24 months). Post-operatively, 15 cases (25.8%) of scapulalgia persisted at 2 months of follow-up, while upper trapezius pain was present in only 22.4%. Scapular dyskinesia was no longer present at 2 months in patients without scapulalgia. The scapular index was measured at 60.42 (52.38-70.96), and the constant score at last follow-up was 76.36 (42-92). CONCLUSION Tenotomy of the pectoralis minor improves painful symptomatology and scapular dyskinesia, in cases of subacromial syndrome with retraction of the pectoralis minor muscle. LEVEL OF EVIDENCE IV, retrospective study.

[PMID: 34972867 DOI: 10.1093/ptj/pzab290] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Revised: 08/20/2021] [Accepted: 11/19/2021] [Indexed: 02/09/2023]
Abstract
OBJECTIVES The aims of this scoping review were to: (1) determine the frequency and types of behavior change techniques (BCTs) and education utilized in trials investigating exercise interventions for rotator cuff related shoulder pain (RCRSP); (2) subcategorize the BCTs and education found in the trials to summarize all behavior change approaches reported by trials; and (3) compare the frequency, types, and subcategories of BCTs and education utilized in the clinical guidelines for managing RCRSP between the trials. METHODS Data sources included Cochrane Central Register of Controlled Trials, Ovid MEDLINE, Ovid EMBASE, CINAHL Plus, Google Scholar and PubMed, which were searched from inception to June 2020. Trials assessing exercise interventions for RCRSP were included. Three authors independently determined eligibility and extracted data. The frequency and types of BCTs and education in the trials and clinical practice guidelines were reported and compared descriptively. Two authors assessed the content of the BCTs to develop subcategories. RESULTS Most trials reported including at least 1 type of BCT (89.2%), which was most commonly feedback and monitoring (78.5%). There were many different approaches to the BCTs and education; for example, feedback and monitoring was subcategorized into supervised exercise, exercise monitoring, and feedback through external aids, such as mirrors. Clinical guidelines recommend supervision, goal setting, activity modification, pain management recommendations, information about the condition, and exercise education. CONCLUSION Although over two-thirds of trials reported including a BCT alongside exercise interventions for RCRSP, the breadth of these interventions is limited (supervision is the only common one). Future trialists should consider using any type of BCT that may improve exercise adherence and outcomes. IMPACT The findings of this review have: (1) identified gaps in the literature; and (2) contributed to the design of future exercise interventions for RCRSP.

Abstract
Background There is no consensus on the best training regimen for subacromial impingement syndrome (SIS). Several have been suggested, but never tested. The purpose of the study is to compare a comprehensive supervised training regimen (STR) based on latest evidence including heavy slow resistance training with a validated home-based regimen (HTR). We hypothesized that the STR would be superior to the HTR. Methods Randomised control trial with blinded assessor. 126 consecutive patients with SIS were recruited and equally randomised to 12 weeks of either supervised training regimen (STR), or home-based training regimen (HTR). Primary outcomes were Constant Score (CS) and Shoulder Rating Questionnaire (SRQ) from baseline and 6 months after completed training. Results were analyzed according to intention-to treat principles. The study was retrospectively registered in ClinicalTrials.gov. Date of registration: 07/06/2021. Identification number: NCT04915430. Results CS improved by 22.7 points for the STR group and by 23,7 points for the HTR (p = 0.0001). The SRQ improved by 17.7 and 18.1 points for the STR and the HTR groups respectively (p = 0.0001). The inter-group changes were non-significant. All secondary outcomes (passive and active range of motion, pain on impingement test, and resisted muscle tests) improved in both groups, without significant inter-group difference. Conclusion We found no significant difference between a comprehensive supervised training regimen including heavy training principles, and a home-based training program in patients with SIS.

Abstract
OBJECTIVES To determine the prevalence of prospective clinical trial registration and postrandomization bias in published musculoskeletal physical therapy randomized clinical trials (RCTs). DESIGN A methods review. LITERATURE SEARCH Articles indexed in MEDLINE and published between January 2016 and July 2020 were included. STUDY SELECTION CRITERIA Two independent blinded reviewers identified the RCTs using Covidence. We included RCTs related to musculoskeletal interventions that were published in International Society of Physiotherapy Journal Editors member journals. DATA SYNTHESIS Data were extracted independently for the variables of interest from the identified RCTs by 2 blinded reviewers. The data were presented descriptively or in frequency tables. RESULTS One hundred thirty-eight RCTs were identified. One third of RCTs were consistent with their prospectively registered intent (49/138); consistency with prospectively registered intent could not be determined for two thirds (89/138) of the RCTs. Four RCTs (8%)reported inconsistent results with the primary aims and 7 (14%) with the outcomes from the prospective clinical trial registry, despite high methodological quality (Physiotherapy Evidence Database [PEDro] scale score). Differences between prospectively registered and non-prospectively registered RCTs for PEDro scale scores had a medium effect size (r = 0.30). Two of 15 journals followed their clinical trial registration policy 100% of the time; in 1 journal, the published RCTs were consistent with the clinical trial registration. CONCLUSION Postrandomization bias in musculoskeletal physical therapy RCTs could not be ruled out, due to the lack of prospective clinical trial registration and detailed data analysis plans.

Abstract
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.

Abstract
Increased muscle stiffness of the pectoralis minor (PMi) could deteriorate shoulder function. Stretching is useful for maintaining and improving muscle stiffness in rehabilitation and sport practice. However, the acute and prolonged effect of stretching on the PMi muscle stiffness is unclear due to limited methodology for assessing individual muscle stiffness. Using shear wave elastography, we explored the responses of shear modulus to stretching in the PMi over time. The first experiment (n = 20) aimed to clarify the acute change in the shear modulus during stretching. The shear modulus was measured at intervals of 30 s × 10 sets. The second experiment (n = 16) aimed to observe and compare the prolonged effect of different durations of stretching on the shear modulus. Short and long stretching duration groups underwent 30s × 1 set and 30s × 10 sets, respectively. The assessments of shear modulus were conducted before, immediately after, and at 5, 10, and 15 min post-stretching. In experiment I, the shear modulus decreased immediately after a bout (30 s) of stretching (p < 0.001, change: -2.3 kPa, effect size: r = 0.72) and further decreased after 3 repetitions (i.e., 90 s) of stretching (p = 0.03, change: -1.0 kPa, effect size: r = 0.53). In experiment II, the change in the shear modulus after stretching was greater in the long duration group than in the short duration group (p = 0.013, group mean difference: -2.5 kPa, partial η 2 = 0.36). The shear modulus of PMi decreased immediately after stretching, and stretching for a long duration was promising to maintain the decreased shear modulus. The acute and prolonged effects on the PMi shear modulus provide information relevant to minimum and persistent stretching time in rehabilitation and sport practice.

Abstract
Background The pectoralis minor (PM) muscle is commonly regarded as a contributor to abnormal scapula positioning. Subsequently, the muscle length of the scapular stabilising muscles may be affected, as these muscles assume a lengthened position, which over time causes weakness. There are inconsistencies regarding PM muscle length values because of the different techniques and positions used when the length of the PM muscle is measured. Objective To determine the PM muscle length in participants aged 18−24 using a Vernier® caliper and expressed as pectoralis minor index (PMI), with the scapula in three different positions. Method The PM muscle length of 144 participants was measured with a Vernier® caliper (intraclass correlation coefficient 0.83−0.87). Measurements were made with the scapula in the resting position, in an active and a passive posterior tilt position. Results Significant differences were observed in PMI between the resting scapula position – 10.04 (confidence interval, CI 9.93–10.14) and active posterior tilt – 10.19 (CI 10.09–10.30) (p < 0.001); the resting position – 10.04 (CI 9.93–10.14) and passive posterior tilt – 10.77 (10.66–10.87) (p < 0.001) and active – 10.19 (CI 10.09–10.30) and passive posterior tilt 10.77 (10.66–10.87) (p < 0.001). The dominant side had lower PMI values than the non-dominant side. Conclusion The significant differences between the active and posterior tilt positions suggested that optimal muscle length of PM was affected by the inner range strength of the lower fibres of Trapezius. Clinical implications It is important that in clinical practice not only the length of PM in scapular misalignment but also the strength of the antagonistic muscles is considered.
