The Effect Of Serratus Anterior Fatigue On Scapular Kinematics, Nathan Curtis Harrison

Theses, Dissertations and Capstones

Background: Shoulder pain is a common occurrence in the general population. Pain has been associated with shoulder impairments and pathology. Associations between shoulder limitations, impairments, and mechanisms of injury and altered scapular motion appear in the literature. Fatigue of the scapular stabilizing muscles resulting from repeated arm motion has been reported to alter scapular kinematics, which could result in shoulder pathology, especially impingement.

Purpose: The purpose of this study was to examine the effects of fatigue of the serratus anterior muscle on scapular kinematics. The hypotheses were that there would be decreased posterior tilt and decreased upward rotation during arm …
