The dependent variable was the change in Active Range of Motion, Supine External Rotation (Humerus abducted to 90°), and the independent variables were groups (Control vs. Physical therapy vs. SDS vs. Combined SDS and Physical Therapy). One-Way Analyses Of Variance (ANOVA) was performed using the Graph-Pad, InStat software, and post-hoc T-tests were performed to measure difference between groups. (An alpha level of 0.05 was used for all tests.) All other calculations were made with the Microsoft Excel program.
