ObjectiveTo investigate the effects of two different exercise programs on three-dimensional scapular kinematics, disability, and pain in participants with subacromial impingement syndrome (SIS).DesignRandomized controlled trial.SettingOutpatient clinic and research laboratory.ParticipantsThirty participants who were diagnosed with SIS and who also exhibited scapular dyskinesis.InterventionsThe participants were randomized in two different exercise groups: 1) shoulder girdle stretching and strengthening with additional scapular stabilization exercises based on a kinetic chain approach (intervention group), and 2) shoulder girdle stretching and strengthening exercises only (control group).Main Outcome MeasuresThree-dimensional scapular kinematics, self-reported shoulder pain, and disability were evaluated at baseline, after 6 weeks of training, and after 12 weeks of training.ResultsSignificant differences were observed between the control and intervention group in external rotation and posterior tilt after 6 weeks of training and in external rotation, posterior tilt, and upward rotation after 12 weeks of training. All groups showed improvement in self-reported pain and disability scores, however there were no significant differences between the groups.ConclusionProgressive exercise training independent from specific scapular stabilization exercises provides decreased disability and pain severity in impingement syndrome.
