Meta-Analysis
OBJECTIVE
To assess the effects of mobilization with movement (MWM) on pain, range of motion (ROM), and disability in the management of shoulder musculoskeletal disorders.
METHODS
Six databases and Scopus, were searched for randomized control trials. The ROB 2.0 tool was used to determine risk-of-bias and GRADE used for quality of evidence. Meta-analyses were performed for the sub-category of frozen shoulder and shoulder pain with movement dysfunction to evaluate the effect of MWM in isolation or in addition to exercise therapy and/or electrotherapy when compared with other conservative interventions.
RESULTS
Out of 25 studies, 21 were included in eight separate meta-analyses for pain, ROM, and disability in the two sub-categories. For frozen shoulder, the addition of MWM significantly improved pain (SMD -1.23, 95% CI -1.96, -0.51)), flexion ROM (MD -11.73, 95% CI -17.83, -5.64), abduction ROM (mean difference -13.14, 95% CI -19.42, -6.87), and disability (SMD -1.50, 95% CI (-2.30, -0.7). For shoulder pain with movement dysfunction, the addition of MWM significantly improved pain (SMD -1.07, 95% CI -1.87, -0.26), flexion ROM (mean difference -18.48, 95% CI- 32.43, -4.54), abduction ROM (MD -32.46, 95% CI - 69.76, 4.84), and disability (SMD -0.88, 95% CI -2.18, 0.43). The majority of studies were found to have a high risk of bias.
DISCUSSION
MWM is associated with improved pain, mobility, and function in patients with a range of shoulder musculoskeletal disorders and the effects clinically meaningful. However, these findings need to be interpreted with caution due to the high levels of heterogeneity and risk of bias.

Review
BACKGROUND
Several studies reported the importance of glenohumeral and scapular muscle activity and scapular kinematics in multidirectional shoulder instability (MDI), yet a systematic overview is currently lacking.
OBJECTIVE
This systematic review evaluates and summarizes the evidence regarding muscle activity and shoulder kinematics in individuals with MDI compared to healthy controls.
METHOD
The electronic databases PubMed and Web of Science were searched in September 2020 with key words regarding MDI (population), muscle activity, and glenohumeral and scapular movement patterns (outcomes). All studies that compared muscle activity or scapular kinematics between shoulders with MDI and healthy shoulders were eligible for this review, except for case reports and case series. All articles were screened on the title and abstract, and remaining eligible articles were screened on full text. The risk of bias of included articles was assessed by a checklist for case-control data, as advised by the Cochrane collaboration.
RESULTS
After full text screening, 12 articles remained for inclusion and one study was obtained by hand search. According to the guidelines of the Dutch Institute for Healthcare Improvement, most studies were of moderate methodological quality. We found moderate evidence that MDI individuals show increased or prolonged activity of several rotator cuff muscles that control and centre the humeral head. Furthermore, we found evidence of decreased and/or shortened activity of muscles that move or accelerate the arm and shoulder girdle as well as increased and/or lengthened activity of muscles that decelerate the arm and shoulder girdle. The most consistent kinematic finding was that MDI individuals show significantly less upward rotation and more internal rotation of the scapula during elevation of the arm in the scapular plane as compared with controls. Finally, several studies also suggest that the humeral head demonstrates increased translations relative to the glenoid surface.
CONCLUSION
There is moderate evidence for altered muscle activity and altered humeral and scapular kinematics in MDI individuals as compared with controls.

Meta-Analysis
OBJECTIVE
To characterise whether preseason screening of shoulder range of motion (ROM) is associated with the risk of shoulder and elbow injuries in overhead athletes.
DESIGN
Systematic review and meta-analysis.
DATA SOURCES
Six electronic databases up to 22 September 2018.
ELIGIBILITY CRITERIA
Inclusion criteria were (1) overhead athletes from Olympic or college sports, (2) preseason measures of shoulder ROM, (3) tracked in-season injuries at the shoulder and elbow, and (4) prospective cohort design. Exclusion criteria were (1) included contact injuries, (2) lower extremity, spine and hand injuries, and (3) full report not published in English.
RESULTS
Fifteen studies were identified, and they included 3314 overhead athletes (baseball (74.6%), softball (3.1%), handball (16.1%), tennis (2.0%), volleyball (2.0%) and swimming (2.2%)). Female athletes are unrepresented (12% of the overall sample). Study quality ranged from 11 to 18 points on a modified Downs and Black checklist (maximum score 21, better quality). In one study, swimmers with low (<93°) or high (>100°) shoulder external rotation were at higher risk of injuries. Using data pooled from three studies of professional baseball pitchers, we showed in the meta-analysis that shoulder external rotation insufficiency (throwing arm <5° greater than the non-throwing arm) was associated with injury (odds ratio=1.90, 95% confidence interval 1.24 to 2.92, p<0.01).
CONCLUSION
Preseason screening of shoulder external rotation ROM may identify professional baseball pitchers and swimmers at risk of injury. Shoulder ROM screening may not be effective to identify handball, softball, volleyball and tennis players at risk of injuries. The results of this systematic review and meta-analysis should be interpreted with caution due to the limited number of studies and their high degree of heterogeneity.

Review
AIM
To synthesize and assess the literature for shoulder pain and injury risk factors in competitive swimmers.
DESIGN
Systematic review with best-evidence synthesis.
DATA SOURCES
CINHAL, SportDiscus, Scorpus, PubMed, and Embase databases from 1966 to April 30 2022.
SEARCH AND INCLUSION
Cohort, cross-sectional, and case-control studies investigating shoulder pain or injury risk factors in competitive swimmers were included. Quality of eligible studies were assessed using a modified Newcastle-Ottawa scale. Risk factors were divided into four categories: modifiable-intrinsic, modifiable-extrinsic, non-modifiable, and other/secondary.
RESULTS
Of 1356 studies identified, 24 full texts were evaluated for methodological quality, 22 met the criteria and were included in best evidence synthesis. There was no strong evidence supporting or refuting the association between 80 assessed variables and shoulder injury or pain. The swimmers' competitive level (nondirectional), and shoulder muscle recruitment profiles (e.g., increased activity of serratus anterior) exhibited moderate evidence supporting an association. Conversely, internal and external range of motion, middle finger back scratch test, training frequency, specialty stroke, height/weight, sex, and age all had moderate evidence opposing an association. Limited evidence was found for 58 variables, and conflicting for 8. The highest quality study (n = 201) suggested high acute-to-chronic workload ratio and reduced posterior shoulder strength endurance are associated with injury.
CONCLUSIONS
Due to the paucity of high-quality studies, future prospective studies are needed to reevaluate known risk factor associations over exploring additional potential risk factors. Swimming practitioners should be aware of the nondirectional association of a swimmer's competitive level and pain, as squad changes could impact injury incidence. Moreover, swimmers experiencing shoulder pain may show increased activity in shoulder stabilizers during specific movements. Importantly, shoulder strength-endurance may be the most clinically relevant modifiable intrinsic risk factor.

Review
OBJECTIVE
To perform a systematic review of clinical practice guidelines (CPGs) covering the management of common shoulder disorders.
DATA SOURCES
A systematic search of CPGs on specific shoulder disorders was conducted up to August 2022 in relevant databases.
STUDY SELECTION
Twenty-six CPGs on rotator cuff (RC) tendinopathy, RC tear, calcific tendinitis, adhesive capsulitis, glenohumeral (GH) instability, GH osteoarthritis, or acromioclavicular disorders published from January 2008 onward were screened and included.
DATA EXTRACTION
CPGs methodological quality was assessed with the AGREE II checklist. All recommendations from CPGs were extracted and categorized by shoulder disorder and care components (evaluation, diagnostic imaging, medical, rehabilitation, and surgical treatments). After semantic analysis of the terminology, recommendations for each shoulder disorders were classified by 2 reviewers into "recommended," "may be recommended," or "not recommended." Disagreements were resolved by discussion until reviewers reached consensus.
DATA SYNTHESIS
Only 12 CPGs (46%) were of high quality with major limitations related to the applicability and editorial independence of the guidelines. The initial evaluation of shoulder pain should include patient's history, subjective evaluation focused on red flags, and clinical examination. Magnetic resonance imaging is usually not recommended to manage early shoulder pain, and recommendations for X-rays are conflicting. Acetaminophen, oral non-steroidal anti-inflammatory drugs, and rehabilitation including exercises were recommended or may be recommended to treat all shoulder pain disorders. Guidelines on surgical management recommendations differed; for example, 6 CPGs reported that acromioplasty was recommended or may be recommended in chronic RC tendinopathy, whereas 4 CPGs did not recommend it.
CONCLUSIONS
Recommendations vary for diagnostic imaging, conservative vs surgical treatment to manage shoulder pain, although several care components are consensual. The development of evidence-based, rigorous CPGs with a valid methodology and transparent reporting is warranted to improve overall shoulder pain care.

Review
Swimming is one of the most popular recreational and competitive sporting activities. In the 2013/2014 swimming season, 9630 men and 12,333 women were registered with the National Collegiate Athletics Association in the USA. The repetitive nature of the swimming stroke and demanding training programs of its athletes raises a number of concerns regarding incidence and severity of injuries that a swimmer might experience during a competitive season. A number of risk factors have previously been identified but the level of evidence from individual studies, as well as the level of certainty that these factors predispose a swimmer to pain and injury, to our knowledge has yet to be critically evaluated in a systematic review. Therefore, the primary objective of this review is to conduct a systematic review to critically assess the published evidence for risk factors that may predispose a swimmer to shoulder pain and injury. Three electronic databases, ScienceDirect, PubMed and SpringerLink, were searched using keywords "(Injury OR pain) AND (Swim*)" and "(Shoulder) AND (Swim*)". Based on the inclusion and exclusion criteria, 2731 unique titles were identified and were analyzed to a final 29 articles. Only articles with a level of evidence of I, II and III were included according to robust study design and data analysis. The level of certainty for each risk factor was determined. No studies were determined to have a high level of certainty, clinical joint laxity and instability, internal/external rotation, previous history of pain and injury and competitive level were determined to have a moderate level of certainty. All other risk factors were evaluated as having a low level of certainty. Although several risk factors were identified from the reviewed studies, prospective cohort studies, larger sample sizes, consistent and robust measures of risk should be employed in future research.

Meta-Analysis Review
The purpose of this study is to establish the absolute reliability between hand-held dynamometers (HHDs) and concurrent validity between HHDs and isokinetic dynamometers (IDs) in shoulder rotator strength assessment. The Medline, CINAHL, and Central databases were searched for relevant studies up to July 2020. Absolute reliability was determined by test-retest studies presenting standard error of measurement (SEM%) and/or minimal detectable change (MDC%) expressed as percentage of the mean. Studies considering intra-class correlation coefficient (ICC) between IDs and HHDs were considered for concurrent validity. The risk of bias and the methodological quality were evaluated according to COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN). Thirteen studies were included in the meta-analysis. Shoulder internal rotator strength assessment MDC% was 0.78%, 95% confidence interval (CI) -5.21 to 3.66, while shoulder external rotators MDC% was 3.29%, CI -2.69 to 9.27. ICC between devices was 0.94, CI (0.91 to 0.96) for shoulder internal rotators and 0.92, IC (0.88 to 0.97) for shoulder external rotators. Very high correlation was found for shoulder rotator torque assessment between HHDs and IDs. The COSMIN checklist classified the selected studies as adequate and inadequate.

Meta-Analysis Review
Short- and long-term outcomes in Bankart repair vs. conservative treatment for first-time anterior shoulder dislocation: a systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
First-time anterior shoulder dislocations are associated with a high rate of residual instability. Therefore, many surgeons support initial Bankart repair surgery over conservative management to address this issue. However, the optimal treatment remains controversial because of uncertainty regarding long-term surgical outcomes. The primary objective of this systematic review and meta-analysis was to compare the short- and long-term rates of residual instability following Bankart repair or conservative management after a first-time anterior shoulder dislocation.
METHODS
PubMed/MEDLINE, Embase, The Cochrane Library, Web of Science, CINAHL, and ScienceDirect databases were accessed for randomized controlled trials (RCTs) comparing Bankart repair to conservative management. RoB (Risk of Bias) 2 was used to check study quality. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) guidelines were followed in assessing primary outcomes. The inverse-variance method for continuous variables and the Mantel-Haenszel method for dichotomous variables was used.
RESULTS
A total of 348 patients from 6 RCTs published across 8 articles, with a mean age of 23.7 years, were included. Bias was graded low in 3 studies, some concerns in 3 studies, and high in 2 studies. In the short term (2-3 years), surgery lowered recurrent instability (risk ratio [RR] 0.15, 95% confidence interval [CI] 0.08, 0.27; I = 0%; P < .0001). Similar findings were seen in the long term (5-12 years) (RR 0.23, 95% CI 0.14, 0.39; I = 0%; P < .0001). No difference was observed in return to sport (RR 1.18, 95% CI 0.91, 1.52; I = 78%; P = .21). Initial surgery lowered subsequent stabilization surgery in the short (RR 0.19, 95% CI 0.09, 0.43; I = 0%; P < .0001) and long term (RR 0.17, 95% CI 0.07, 0.39; I = 25%; P < .0001). Western Ontario Shoulder Instability Index (WOSI) scores did not differ in the short term (MD, 2.54, 95% CI -0.51, 5.59; I = 48%; P = .1) but were higher in the surgical group at long-term follow-up. Patient satisfaction was also higher with surgery (RR 1.75, 95% CI 1.4, 2.2; I = 88%; P < .0001). Certainty of evidence was low for only 1 long-term outcome measure.
CONCLUSION
Bankart repair surgery for first-time anterior shoulder dislocation results in a large reduction in the risk of recurrent shoulder instability and subsequent stabilization surgery in both short- (2-3 years) and long-term (5-12 years) follow-up intervals. Additionally, slight improvements in overall patient satisfaction and WOSI score can be seen at long-term follow-up. However, surgical intervention failed to significantly improve the rate of return to sport when compared with conservative management.

Meta-Analysis Review
PURPOSE
The extent of shoulder instability and the indication for surgery may be determined by the prevalence or size of associated lesions. However, a varying prevalence is reported and the actual values are therefore unclear. In addition, it is unclear whether these lesions are present after the first dislocation and whether or not these lesions increase in size after recurrence. The aim of this systematic review was (1) to determine the prevalence of lesions associated with traumatic anterior shoulder dislocations, (2) to determine if the prevalence is higher following recurrent dislocations compared to first-time dislocations and (3) to determine if the prevalence is higher following complete dislocations compared to subluxations.
METHODS
PubMed, EMBASE, Cochrane and Web of Science were searched. Studies examining shoulders after traumatic anterior dislocations during arthroscopy or with MRI/MRA or CT published after 1999 were included. A total of 22 studies (1920 shoulders) were included.
RESULTS
The proportion of Hill-Sachs and Bankart lesions was higher in recurrent dislocations (85%; 66%) compared to first-time dislocations (71%; 59%) and this was statistically significant (P < 0.01; P = 0.05). No significant difference between recurrent and first-time dislocations was observed for SLAP lesions, rotator-cuff tears, bony Bankart lesions, HAGL lesions and ALPSA lesions. The proportion of Hill-Sachs lesions was significantly higher in complete dislocations (82%) compared to subluxations (54%; P < 0.01).
CONCLUSION
Higher proportions of Hill-Sachs and Bankart were observed in recurrent dislocations compared to first-time dislocations. No difference was observed for bony Bankart, HAGL, SLAP, rotator-cuff tear and ALPSA. Especially when a Hill-Sachs or Bankart is present after first-time dislocation, early surgical stabilization may need to be considered as other lesions may not be expected after recurrence and to limit lesion growth. However, results should be interpreted with caution due to substantial heterogeneity and large variance.

Review
OBJECTIVE
To conduct a systematic review of the quality and content of the psychometric evidence relating to 4 shoulder disability scales: the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, the Shoulder Pain and Disability Index (SPADI), the American Shoulder and Elbow Surgeons (ASES) score, and the Simple Shoulder Test (SST).
METHODS
We conducted a structured search using 3 databases (Medline, CINAHL, EMBase). In total, 71 published primary studies were analyzed. A pair of raters conducted data extraction and critical appraisal using structured tools. A descriptive synthesis was performed.
RESULTS
Quality ratings of 55% of the studies reviewed reached a level of > or =75%. Most studies suggest that all 4 questionnaires have excellent reliability (intraclass correlation coefficient > or =0.90). The 4 questionnaires are strongly correlated (r >0.70) with each other and with a number of similar indices, and the questionnaires were able to differentiate between different populations and disability levels. The minimal detectable change (MDC) is approximately 9.4 for the ASES, 10.5 for the DASH, and 18 for the SPADI; the minimal clinically important difference (MCID) is approximately 6.4 for the ASES and 10.2 for the DASH, and ranges between 8 and 13 for the SPADI. MDC and MCID have not been defined for the SST.
CONCLUSION
The psychometric properties of the ASES, DASH, and SPADI have been shown to be acceptable for clinical use. Conversely, some properties of the SST still need be evaluated, particularly the absolute errors of measurement. Overall, validation studies have focused on less clinically relevant properties (construct validity or group reliability) than estimates of MDC and MCID.
