Abstract
Purpose: The purpose of this study is to investigate how participation in the eccentric contraction exercise program affects pain & function, range of motion, and muscle strength in patients with subacromial impingement syndrome.<BR> Method: The subjects of the study were 20 female patients diagnosed with subacromial impingement syndrome in the age of 40s-50s. They were allocated wirelessly to the ECG group and the AGG group. Data processing was two-way repeated ANOVA, paired t-test and independent t-test. A significant level of hypothesis verification was set-up (p<.05).<BR> Results: The results of this study are as follows. 1) OSS was significantly improved in all of the timing, interaction, and group (p<.001). And in comparison between groups, ECG improved significantly (p<.01). 2) The change in ROM of Flexion was significantly improved in timing (p<.001), interaction (p<.05), and group (p<.001). ECG was significantly improved in comparison between groups (p<.001). The change in ROM of Abduction was significantly improved in timing (p<.001), interaction (p<.05), and group (p<.001). And ECG was significantly improved in comparison between groups p(<.001). The change in ROM of external rotation was significantly improved in all of the timing, interaction, and group (p<.001). In comparison between groups, ECG was significantly improved (p<.001). 3) The change in external rotation strength was significantly improved in time, interaction (p<.001), and group (p<.01). In the comparison between groups, ECG was found to be significantly improved (p<.001).<BR> Conclusion: Therefore, the eccentric contraction exercise program implemented in this study appears to be an effective treatment method for symptomatic improvement in patients with subacromial impingement syndrome, and future studies will require comparative studies involving gender, various age groups, and more patients with impingement syndrome.
