A Comparison of Shoulder Stabilizer Muscle Activities of Therapeutic Climbing and Isometric Exercise in Patients with Shoulder Impingement Syndrome

다국어 초록 (Multilingual Abstract)

Purpose: The purpose of this study was to compare therapeutic climbing exercise and general isometric exercise in patients with shoulder impingement syndrome. Methods: Among 20 adults, study subjects were arbitrarily classified into an experimental group of 10 and a control group of 10. The control group performed general isometric exercise (ISE) and the experimental group performed therapeutic climbing exercise (TC) (3 sets, 3 times per week for 8 weeks). To evaluate the effects of exercise, subjects were evaluated using a Disabilities of the arm, shoulder and hand score (DASH), a goniometer for range of motion, and shoulder activity measured serratus anterior, upper trapezius, and lower trapezius. Independent and paired t-test were used for comparison of the effect between groups. Results: DASH scores showed a significant decrease in both groups after 8 weeks of treatment (p<0.001) and significant difference was observed between the TC groups (p<0.01). Flexion and abduction were significantly increased after 8 weeks of treatment in the ISE group (p<0.001) and flexion, abduction, external and internal rotation were significantly increased after 8 weeks of treatment in the TC group (p<0.001). Serratus anterior and lower trapezius activity were significantly increased after 8 weeks of treatment (p<0.001) and upper trapezius activity was not significantly increased after 8 weeks of treatment in the ISE group (p>0.05). Serratus anterior, lower trapezius, and upper trapezius activity were significantly increased after 8 weeks of treatment in the TC group (p<0.001). Conclusion: Scapular stabilizing exercise using a therapeutic climbing exercise increases range of motion and decreases DASH, and increases activity of shoulder muscles in patients with impingement syndrome.
