Glenohumeral internal rotation deficits (GIRD) have been found in overhead athletes but comparisons of GIRD between sports has not been closely investigated. With the different performance demands of the shoulder, depending on the sport involved, produce different ranges of GIRD. Comparisons between overhead motion athletes, non-overhead and sporadic overhead motion athletes may indicate GIRD. These rotational differences may also occur acutely or over time. The objective of this study was to analyze the presence of GIRD between overhead non-overhead, and part-time overhead athletes.
