Comparison of Glenohumeral Range of Motion Deficits in Youth, Collegiate, and Professional Baseball Players.

Background: Examining range of motion deficits across levels of baseball competition can result in a better understanding of the extent of altered range of motion patterns and identify competition levels that may require preventative interventions that target the deficits.

Purpose: The purpose of this study was to compare shoulder range of motion in baseball players across levels of competition and compare the prevalence of glenohumeral internal rotaton deficit (GIRD) and total arc of motion differences (TAMD) between competition levels in pitchers and position players.

Study Design: Prospective descriptive cohort.
