BACKGROUND: Scapular instability is related to shoulder impingement syndrome. Therefore, the recognition of scapular instability is very important for the effective treatment of shoulder impingement syndrome. The aim of this study was to investigate the use of visual feedback to improve the effects of scapular stabilization exercises on patients with shoulder impingement syndrome.
MATERIAL AND METHODS: Forty-five patients with shoulder impingement syndrome were randomly allocated to a visual scapular stabilization exercise (VSSE) group (n=23) or a non-visual scapular stabilization exercise (NVSSE) group (n=22). The VSSE group received visual feedback on scapular stabilization exercises using a video camera, and scapular movement education using a 3D motion image program. The NVSSE group performed the same scapular stabilization exercises without the visual feedback. Both groups underwent training for 20 minutes a day, three times a week, over four weeks. All subjects were evaluated by using the numeric pain rating scale (NPRS), range of motion, strength, and the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire (Q-DASH).
RESULTS: The NPRS, range of motion, strength, and Q-DASH scores showed significant differences in both groups (p<0.05). In addition, all of the dependent variables showed significant improvements in the VSSE group compared to the NVSSE group.
CONCLUSIONS: Visual information might improve the effectiveness of scapular stabilization exercises on pain intensity, range of motion, flexion muscle strength, and disabilities in patients with shoulder impingement syndrome.
