Context: Shoulder injuries are highly prevalent in sports involving the upper extremity. Some risk factors have been identified in the literature, but consensus is still lacking. Objectives: To identify risk factors of overuse shoulder injury in overhead athletes, as described in the literature. Data Sources: A systematic review of the literature from the years 1970 to 2018 was performed using 2 electronic databases: PubMed and Scopus. Study Selection: Prospective studies, written in English, that described at least 1 risk factor associated with overuse shoulder injuries in overhead sports (volleyball, handball, basketball, swimming, water polo, badminton, baseball, and tennis) were considered for analysis. Study Design: Systematic review. Level of Evidence: Level 3. Data Extraction: Data were extracted from 25 studies. Study methodology quality was evaluated using the Modified Coleman Methodology Score. Results: Intrinsic factors, previous injury, range of motion (lack or excess), and rotator cuff weakness (isometric and isokinetic) highly increase the risk of future injuries. Additionally, years of athletic practice, body mass index, sex, age, and level of play seem to have modest influence. As for the effect of scapular dysfunction on shoulder injuries, it is still controversial, though these are typically linked. Extrinsic factors, field position, condition of practice (match/training), time of season, and training load also have influence on the occurrence of shoulder injuries. Conclusion: Range of motion, rotator cuff muscle weakness, and training load are important modifiable factors associated with shoulder injuries. Scapular dysfunction may also have influence. The preventive approach for shoulder injury should focus on these factors.

Background: Underlying muscle weakness and stiffness may increase the risk of developing rotator cuff tendinopathy. This systematic review aims to assess existing prospective studies to summarize whether muscle weakness and stiffness are risk factors for the development of rotator cuff tendinopathy in overhead athletes. Methods: A systematic search was performed using PRISMA guidelines. Prospective studies measuring muscle strength or stiffness and the incidence of rotator cuff tendinopathy were included. Quality assessment was performed with the Newcastle-Ottawa quality assessment scale. Results: The search yielded six studies, with a total of 523 trained overhead athletes followed up for one season. External rotation (ER) and internal rotation (IR) strength were described as protective factors against the development of rotator cuff tendinopathy. Athletes who did not sustain shoulder injuries had statistically stronger eccentric IR ( p < 0.01) and ER ( p < 0.05) strength in the pre-season assessment. Muscle stiffness indicated by limited range of motion of <106° for shoulder ER was described as a risk factor with an odds ratio of 1.12 ( p < 0.001). Imbalance between ER and IR strength was reported as risk factors for shoulder injuries in two studies, with a relative risk of 2.57 ( p < 0.05) reported in one study. Supraspinatus weakness was also reported as a risk factor for shoulder injuries in one study. Conclusion: Limited evidence support ER, IR weakness, limited ER range of motion, and very limited evidence support imbalance in ER/IR strength, and supraspinatus weakness as risk factors for rotator cuff tendinopathy in overhead athletes. No existing studies investigated the general population on this topic. Future cohort studies may improve on existing evidence with investigations on the general public, a longer follow-up time, clearly documented injury history, and a stringent diagnosis to rotator cuff tendinopathy.

ObjectiveTo assess the evidence for risk factors and prevention measures for shoulder injuries in overhead sports.DesignSystematic review with best-evidence synthesis.Data sourcesMedline (Ovid), PubMed (complementary search), Embase (Elsevier), Cochrane (Wiley), SPORTDiscus (Ebsco) and Web of Science Core Collection (Thomson Reuters), from 1 January 1990 to 15 May 2017.Eligibility criteria for selecting studiesRandomised controlled trials, cohort studies and case-control studies on risk factors or prevention measures for shoulder injuries in overhead sports. The eligible studies were quality assessed using the Scottish Intercollegiate Guidelines Network criteria.ResultsOf 4778 studies identified, 38 were eligible for quality review and 17 met the quality criteria to be included in the evidence synthesis. One additional quality study presented a shoulder injury prevention programme. Most studies focused on baseball, lacrosse or volleyball (n=13). The risk factors examined included participation level (competition vs training) (n=10), sex (n=4), biomechanics (n=2) and external workload (n=2). The evidence for all risk factors was limited or conflicting. The effect of the prevention programme within the subgroup of uninjured players at baseline was modest and possibly lacked statistical power.ConclusionsAll investigated potential risk factors for shoulder injury in overhead sports had limited evidence, and most were non-modifiable (eg, sex). There is also limited evidence for the effect of shoulder injury prevention measures in overhead sports.PROSPERO trial registration numberCRD42015026850.

ABSTRACT Shoulder injuries are very common in cricketers. Throwing athletes in cricket (both bowlers and fielders) are prone to shoulder injuries secondary to the large amount of forces generated, the resultant very high velocities and the repetitive nature of the throwing action. The shoulder joint has to balance mobility vs stability. Athletes exhibit adaptive changes that develop from the repetitive microtrauma following overhead throwing. The article discusses in detail how altered scapular kinematics, rotator cuff dysfunction with altered muscle strength patterns, internal impingement combined with anatomical adaptive bony and soft tissue changes causing a glenohumeral internal rotation deficit, predispose the cricketer to shoulder injury.

PURPOSE: Cellists sustain high levels of playing-related injury and are particularly susceptible to right shoulder pain, yet no studies have attempted to propose a mechanism for disease or establish possible causal factors. The aim of this study was to investigate shoulder injury levels and causes in two populations: professional orchestral cellists and college-level student cellists. METHODS: A questionnaire and physical testing protocol was applied to both groups of participants, eliciting information on lifestyle, playing habits, and self-reported injury rates as well as physical data on shoulder strength, range of motion, and signs of injury. RESULTS: Right shoulder injuries are common among both student (20%) and professional (42%) cellists and seem to be associated with measures indicating potential lack of strength in the scapular stabilisers as well as potential degenerative changes in the rotator cuff. Significant differences were found in the lifestyle and playing habits of the two groups. There were increased signs of pain and stiffness in the professionals and evidence of decreased muscular support in the students. Male cellists showed less scapular stability; female cellists, however, generally had higher levels of pain. CONCLUSIONS: These results indicate that injuries at the shoulder, potentially involving impingement-type pathologies, are a common cause of pain in cellists. Based on this study, future research for cello players could focus on targeted interventions, such as exercises for the scapular stabilisers and muscles of the rotator cuff.

Context: Current perception dictates that glenohumeral internal rotation deficit (GIRD) is a chronic adaptation that leads to an increased risk of pathologic conditions in the dominant shoulder or elbow of overhead athletes. Objective: To determine whether adaptations in glenohumeral range of motion in overhead athletes lead to injuries of the upper extremity, specifically in the shoulder or elbow. Data Sources: An electronic database search was performed using Medline, Embase, and SportDiscus from 1950 to 2016. The following keywords were used: GIRD, glenohumeral internal rotation deficit, glenohumeral deficit, shoulder, sport, injury, shoulder joint, baseball, football, racquet sports, volleyball, javelin, cricket, athletic injuries, handball, lacrosse, water polo, hammer throw, and throwing injury. Study Selection: Seventeen studies met the inclusion criteria for this systematic review. Of those 17 studies, 10 included specific range of motion measurements required for inclusion in the meta-analysis. Study Design: Systematic review and meta-analysis. Level of Evidence: Level 4. Data Extraction: Data on demographics and methodology as well as shoulder range of motion in various planes were collected when possible. The primary outcome of interest was upper extremity injury, specifically shoulder or elbow injury. Results: The systematic review included 2195 athletes (1889 males, 306 females) with a mean age of 20.8 years. Shoulders with GIRD favored an upper extremity injury, with a mean difference of 3.11° (95% CI, –0.13° to 6.36°; P = 0.06). Shoulder total range of motion suggested increased motion (mean difference, 2.97°) correlated with no injury ( P = 0.11), and less total motion (mean difference, 1.95°) favored injury ( P = 0.14). External rotational gain also favored injury, with a mean difference of 1.93° ( P = 0.07). Conclusion: The pooled results of this systematic review and meta-analysis did not reach statistical significance for any shoulder motion measurement and its correlation to shoulder or elbow injury. Results, though not reaching significance, favored injury in overhead athletes with GIRD, as well as rotational loss and external rotational gain.

Purpose: Rotator cuff tears (RCTs) occur commonly, especially among certain groups of individuals. In this meta-analysis, we aim to identify risk factors for RCTs. Methods: We searched MEDLINE for 210 articles. Seventeen articles were selected for systematic review, of which 10 were eligible for meta-analysis. Data was analysed with Review Manager 5.3, using Mantel–Haenszel statistics and random effect models. Results: A total of 6653 individuals were analysed. The odds of sustaining a RCT on the dominant hand was 2.30 times more than the non-dominant hand (95% confidence interval (CI): 1.01–5.25, Z = 1.99, p = 0.05; Heterogenity: τ2 = 0.38, χ2 = 8.84, df = 2 ( p = 0.01), I2 = 77%). The odds of an individual aged 60 years and above sustaining a RCT was 5.07 times higher than an individual less than 60 years old (95% CI: 2.45–10.51, Z = 4.37, p < 0.001; Heterogenity: τ2 = 0.47, χ2 = 25.24, df = 3 ( p < 0.001), I2 = 88%). Female gender was not a significant association, with an odds ratio of 0.98 when compared to the male gender (95% CI: 0.66–1.45, Z = 0.09, p = 0.93; Heterogenity: τ2 = 0.20, χ2 = 44.24, df = 5 ( p < 0.001), I2 = 89%). Conclusions: Hand dominance and older age are associated with RCTs. More studies are required for further assessment of associations and risk factors of RCTs.
