Strength and activity of the protractor and retractor muscles of the asymptomatic dyskinetic scapula.

The role of scapular dyskinesis as a risk factor of shoulder injury has been largely discussed. However, most studies have focused on symptomatic patients and less is known on the asymptomatic dyskinetic scapula. Removing the confounding effects of the pathologies could contribute to better characterize the scapula dyskinesis.

Upper limb functional testing in athletes: A Delphi study.

Background: Functional testing has recently become more and more popular to assess athletes, both for injury prevention, as well as in an objective of performance. However, the relationship between the results of these tests and performances (or injuries) or their interpretation remains unclear.

Objective: The aim of this study is to explore the usefulness, the characteristics, and the interpretation of the most frequently used upper-limb functional test.

Return to play decision after shoulder dislocation in upper limb athletes: Critical analysis between the habits of medical professionals and the literature.

Background: The return to field is a critical moment for an athlete who has dislocated his shoulder as there is a significant risk of recurrence. The decision to return to field made by the doctor will therefore be crucial for the smooth continuation of the athlete's career.

Hypothesis: This objective is to compare the criteria most used by specialists in clearing an overhead athlete to return to competition after a first episode of antero-internal dislocation of the glenohumeral joint with or without surgery and those mentioned in the literature.

Prevention of shoulder injuries in volleyball players: The usefulness and efficiency of a warm-up routine.

Objectives: The objective of this study was to assess the efficiency of a warm-up routine focused on shoulder injury prevention in volleyball players.

Design: Prospective study.

Setting: University.

Differences in Strength and Fatigue Resistance of Scapular Protractors and Retractors Between Symptomatic and Asymptomatic Dyskinesis.

Context: Scapular dyskinesis is a shoulder dysfunction that can be asymptomatic or associated with pain or weakness. Reduced strength and fatigue resistance of the scapular protractor and retractor muscles that stabilize the scapula might contribute to dyskinesis.

Objectives: To determine the strength and fatigue resistance profiles of participants with symptomatic or asymptomatic scapular dyskinesis and compare them with healthy control (HC) individuals using isokinetic assessment.

Preseason shoulder screening in volleyball players: is there any change during season?

Background: Volleyball players sollicit their shoulder with high velocity and high ranges of motion. Musculoskeletal adaptations have been described after some years of practice but have not been explored after some months of practice. The objective of this study was to analyze the short-term evolution of shoulder clinical measures and functional performance in youth competitive volleyball players.

The Modified-Athletic Shoulder Test: Reliability and validity of a new on-field assessment tool.

Objectives: To assess the reliability and the validity of a modified version of the Athletic Shoulder Test (M-AST), using a handheld dynamometer instead of a force plate.

Design: Test-retest reliability and concordance between tools.

Setting: University Motion Lab.

The influence of growth and development on shoulder rotators strength in young male and female elite tennis players.

Background: Tennis practice requires a lot of technical, physical and mental qualities that have to be trained from the youngest age. The important number of hours spent on the court can lead, medium-to-long term to strength or flexibility adaptations, even in the youngest players. The current study aimed to explore the developmental consequences of repetitively playing tennis on shoulder range of motion and shoulder rotators' strength in elite male and female tennis players.

Risk Factors of Overuse Shoulder Injuries in Overhead Athletes: A Systematic Review.

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.
