발목관절의 질병유무가 고관절의 등속성 근기능에 미치는 영향

The purpose of this study was to examine the relationship between chronic ankle sprain and hip and ankle muscle weakness on the involved side in female college students, then to identify the relationship between the muscle strength of hip and ankle joint and isokinetic test. Biodex system 3 model (Biodex Medical Systems, Inc., N.Y., U.S.A) was used. The means and standard deviations were obtained using SPSS 12.0(ver. Kor) statistical software. t-tests were performed to determine difference in the isokinetic values between contra lateral and ipsi lateral hipand ankle joint. A toltal of24 female college students who haduni lateral chronic ankle sprain at least twice with in a year were recruited from Swomen’s University. Their contra lateral and ipsi lateral hip and ankle joint isokinetic value was compared. The results are as follows.
1. With hip abduction at angular velocity of 30°/sec, peak torque, peak torque per body weight ,and total work variables were significantly less on involved side than the uninvolved side (p<.05)2. With ankle eversion at angular velocity of 30°/sec, peak torque, peak torque per body weight, and total work variables and with ankle eversion at angular velocity of 180°/sec, peak torque per body weight were significantly less on involved side than the uninvolved side (p<.05)
