The aim of this study was to investigate the effects of scapular dynamic stabilization exercise(SDex) with electromyography(EMG) biofeedback on the upper trapezius(UT), pectoralis major(PM) and serratus anterior(SA) activities. Fifteen healthy male voluntarily participated in this study. A paired t-test was used for statistical analysis. The study showed, through EMG biofeedback, that EMG activity significantly decreased in the UT, PM and increased in the SA(P<0.05). These results suggest that SDex with EMG biofeedback is effective to selectively strengthen the SA. This article is meaningful in that it is the first article using SDex with EMG biofeedback.
