  • The purpose of this study was to determine whether or not the S3 scapular stabilizing brace corrects the posture of participants with FHRSP. In addition, this study determined whether or not wearing the S3 scapular stabilizing brace has an effect on the muscle activity of participants with FHRSP while performing six scapular stabilization exercises. Posture was measured using a digital camera and Adobe Photoshop to determine both the forward head and rounded shoulder angles. Muscle activity was measure for the upper trapezius, middle trapezius, lower trapezius, and serratus anterior using the average EMG recorded during Y', T's, W's, shoulder extension, forward flexion, and scapular punches. This study found that there were significant changes in FSA and upper, middle, and lower trapezii EMG activity caused when wearing the S3 brace compared to not wearing it. However, this study did not find significant differences in the treatment group compared to the sham group for FHRSP or EMG activity in any muscles.
