ABSTRACT

The aim of this study is to observe the effects of the shoulder stabilizing exercise using sling on the imbalance ratio of trapezius muscle activity and active range of motion (AROM) of shoulder joint. A total of 15 participants with chronic shoulder pain were participated and assigned into two groups; Intervention group that performed shoulder stabilization exercise for 4 weeks and control group that did not perform exercise. Muscle activities of the upper and lower trapezius muscle during 120-degree abduction and AROM during shoulder abduction were measured before and after 4-week intervention. As a result, there were significant changes both in the imbalance ratio and AROM after 4 weeks only in the intervention group (p < 0.05). In conclusion, shoulder stabilization exercise using sling would be effective in improving shoulder function by normalizing the imbalance ratio of muscle activity in terms of motor control.
