Should Range of Motion Measures as Risk Factors for Shoulder and Elbow Injuries in High School Softball and Baseball Players
(Shanley, et al.; The American Journal of Sports Medicine; June 17, 2011)
- High school softball and baseball players (n=246) participated. Before the start of the season, passive shoulder external rotation (ER), internal rotation (IR) and horizontal adduction (HA) were assessed and then these participants were followed throughout the season to determine whether there were any characteristics predictive of shoulder and elbow injuries.
- There are large mean deficits in shoulder IR and HA between injured and non-injured players, but not in ER or total rotation. Passive shoulder IR loss of greater than or equal to 25 degrees as compared bilaterally was predictive of arm injury. Shoulder range-of-motion deficits were more predictive for baseball players than softball players.
