Deficits in Glenohumeral Passive Range of Motion Increase Risk of Shoulder Injury in Professional Baseball Pitchers: A Prospective Study.

Background: Shoulder injuries from repetitive baseball pitching continue to be a serious, common problem.

Purpose: To determine whether passive range of motion of the glenohumeral joint was predictive of shoulder injury or shoulder surgery in professional baseball pitchers.

Study Design: Cohort study; Level of evidence, 2.

Deficits in glenohumeral passive range of motion increase risk of elbow injury in professional baseball pitchers: a prospective study.

Background: Injuries to the elbow joint in baseball pitchers appear common. There appears to be a correlation between shoulder range of motion and elbow injuries.

Purpose: To prospectively determine whether decreased ROM of the throwing shoulder is correlated with the onset of elbow injuries in professional baseball pitchers.

Glenohumeral internal rotation measurements differ depending on stabilization techniques.

Background: The loss of glenohumeral internal rotation range of motion in overhead athletes has been well documented in the literature. Several different methods of assessing this measurement have been described, making comparison between the results of studies difficult.

Hypothesis: Significant differences in the amount of internal rotation range of motion exist when using different methods of stabilization.
