다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate the change of muscular function, degree of pain and body composition of female elderly ten persons with knee osteoarthritis and obesity after 12 weeks. During this periods the subjects performed isometric exercise at the specific knee joint angle without pain(15° 10° 5° in this study) and aerobic exercise to reduce the obesity that is primary risk factor of knee osteoarthritis. The results of all the variables are as followed: 1. The aspects of muscular function tested in isokinetic machine: 1) There were statistically significant differences in the peak torque, peak torque %body weight, total work, total work %body weight of extensor muscles between affected and normal knee joints, but not statistically significant differences in all variables of flexor muscles between affected and normal knee joints in the isokinetic angluar velocity of 60° /second before exercise. 2) There were statistically significant differences in all variables of extensor muscles between affected and normal knee joints, but not statistically significant differences in all variables of flexor muscles of affected and normal knee joints in the isokinetic angluar velocity of 60° /second after exercise. 3) There were statistically significant differences in all variables of extensor muscles between affected and normal knee joints, but not statisticallly significant differences in all variables in flexor muscles of affected and normal knee joints in the isokinetic angluar velocity of 180° /sec before exercise. 4) Although there were statistically significant differences in the peak torque and peak torque %body weight of extensor muscles between affected and normal knee joints, the other factors, total work and total work %body weight, were not statistically significant different at the isokinetic angluar velocity of 180° /sec after exercise. But there were not statisticall y significant differences in all variables in flexor muscles of affected and normal knee joints in the isokinetic angluar velocity of 180° /sec after exercise. 5) There were statistically significant differences in all variables of an affected extensor muscle but the peak torque and total work of an affected flexor muscle were not a significant different at the isokinetic angluar velocity of 60° /sec after exercise. But there were statistically significant differences in all variables of normal extensor and flexor muscles at the isokinetic angluar velocity of 60° /sec after exercise. 6) There were statistically significant differences in all variables in an affected extensor muscle but all variables in an affected flexor muscle were not a significant different at the isokinetic angluar velocity of 180° /sec after exercise. Although there were statistically significant differences in the peak torque, peak torque %body weight, total work %body weight of an normal extensor muscle, total work was not statistically significant different. But all variables of an normal flexor muscle were statistically significant different at the isokinetic angluar velocity of 180° /sec after exercise 2. There was not a statistically significant difference in weight, muscle mass, body fat and % body fat to observe the change of body composition between pre and post exercise. 3. There is a statistically significant difference in the pain score showing change of the degree of pain between pre and post exercise. As a conclusion, the patients with a knee joint osteoarthitis in this study can be improved in the muscular function and the pain degree but not be changed in body composition after 12 weeks. In the future, when we compose the exercise program for osteoarthitis patients, we think that the following reserch must be planed to prolonging therapy periods over 12 weeks` program which do not endowed without loads on the knee joints or can change the body composition.
