説明
Shoulders with rotator cuff tears were divided into 3 groups according to pain: those who have pain at present (symptomatic group), had pain in the past but not at present (ex-symptomatic group) and have not had pain (asymptomatic group). The purpose of this study was to clarify the differences in muscle strength among these 3 groups with isolated tears of the supraspinatus. There were 31 shoulders in the symptomatic group, 21 in the ex-symptomatic group and 66 in the asymptomatic group. The abduction strength and external rotation strength in adduction were assessed with the use of a manual muscle test and compared among the groups. Abduction weakness was observed in 52%, 33% and 38% in the symptomatic group, the ex-symptomatic group and the asymptomatic group, respectively. There were no significant differences among them. Weakness in external rotation was observed in 52%, 10%, and 39% in the symptomatic, ex-symptomatic, and asymptomatic groups, respectively. External rotation strength was significantly weaker in the ex-symptomatic group than the others (symptomatic and ex-symptomatic group, p=0.002; ex-symptomatic and asymptomatic group, p=0.01). Well preserved strength in external rotation is characteristic to ex-symptomatic shoulders with isolated tears of the supraspinatus.
