RELIABILITY OF THE SITTING HAND PRESS-UP TEST FOR IDENTIFYING AND QUANTIFYING THE LEVEL OF SCAPULAR MEDIAL BORDER POSTERIOR DISPLACEMENT IN OVERHEAD ATHLETES

Background: The lack of proper scapular kinematics can limit the function of the entire shoulder complex.1,3 Many forms of scapular dyskinesis have been proposed along with tests to measure for the position and motion associated with those positional and movement faults (2,4-6). While scapular internal rotation has been listed among the forms of scapular dyskinesis there has not been a reliable test documented in the literature that examines this motion. The purpose of this study was to determine whether an innovative scapular medial border posterior displacement measurement device has adequate inter-rater and intra-rater reliability when used at rest and during the sitting hand press up test.
