88 adolescents with a forward head and protracted shoulder posture were included in the study. Patients were randomized to either an intervention group, which underwent a 32 week resistance and stretching exercise program followed by a 16 week detraining period, or a control group. The study was conducted in order to determine whether the exercise program was able to improve cervical and shoulder angles in patients and in turn improve function and pain outcomes, and if these potential improvements were maintained after exercise was ceased. Although the training group reported significantly improved cervical and shoulder angles which were maintained after the detraining period, angles were largely comparable to those in the control group. Additionally, the improved posture did not translate to better clinical outcomes.
