충돌증후군에서 견봉하 공간에 Lidocaine주사 전후 회전근 개 근력의 변화 = The Strength of Rotator cuff in Impingement Syndrome before and after the Subacromial Injection of Lidocaine

다국어 초록 (Multilingual Abstract)

-The purpose of this study is to evaluate the strength of the shoulder before and after the impingement test using lidocaine injection in impingement syndrome. Between January 2002 and February 2005, 153 cases of the impingement syndrome were included in this study. We checked the muscle strength of supraspinatus, internal rotator and external rotator of the shoulder before and after the impingement test. We divided the group into 2 subgroups according to the average percentage decrease in pain to evaluate the correlation between pain and muscle weakness. And we devided the group into 2 groups according to the average age, sex, and stiffness respectively. Pain after the impingement test compared with that before the test decreased 67.1%. Pain in impingement syndrome without stiffness compared with that with stiffness was significantly lower after the test. The results showed no statistically significant difference in the strength of the shoulder except for increased supraspinatus strength in impingement syndrome with stiffness after the test. In case which the continuity of the rotator cuff is maintained, pain is not an important factor in the causes of shoulder weakness in this study. But in same case, particularly with shoulder stiffness, the supraspinatus strength can be decreased.
