Scapular muscles strength in college baseball players with and without a history of UCL injury.

Background: Ulnar collateral ligament (UCL) injuries are common in overhead athletes and have increased in prevalence among baseball pitchers of all ages. The purpose of this study was to examine the difference between the strength of five scapular stabilizing muscles in college baseball pitchers with and without a history of UCL surgery. Data on a pitcher with a recent diagnosis of a Grade I UCL sprain was also included as a case study.
