Background: The shoulder is injury prone and subacromial impingement syndrome (SAIS) is one of the most diagnosed causes of pain in the region.
Objective: The purpose of this study was to investigate muscle activity between healthy and SAIS shoulders on the same subject and to understand the effectiveness of EMG biofeedback (EBFB) on bilateral overhead movements.
Design: Ten participants (7 male), that tested positive for 2/3 SAIS clinical tests, volunteered for the study. Bilateral muscle activity was measured via electrodes on the Upper Trapezius (UT), Lower Trapezius (LT), Serratus Anterior (SA), and Lumbar Paraspinals (LP). Kinematic testing involved 3 continuous …
