Purpose: The purpose of this study was to investigate the effect of movement training based on motor control theory on pain and average power of muscles in patients with shoulder impingement syndrome and to develop more effective training methods. Methods: We studied 35 patients with shoulder impingement syndrome. Patients were randomly assigned to an experimental group or a control group according to the intervention. The therapeutic modalities such as superficial heat, deep heat, and electronic stimulus, and motor control training with strengthening exercises were applied to the experimental group and therapeutic modalities only were applied to the control group. All interventions were done 3 times a week for 4 weeks. Before the intervention and again after the 4 weeks, we measured pain utilizing a visual analog scale. We measured average power using isokinetic equipment. Results: After application of the intervention, pain significantly decreased in both the experimental group and the control group. There was a significant difference between the extent of the decrease between experimental and control groups. After the intervention, the average power between the two groups were significant at an angle of 60°/sec and 180°/sec for external rotator and internal rotator muscles. They also showed significant improvement in all variables post-intervention compared to pre-intervention. Conclusion: This study indicates that there is an effect in giving appropriate motor control training to patients with shoulder impingement syndrome. It is assumed that there will be a need for more surveys on various variables for motor control training from now on.
