This study sued Cybex 6000 to assess and compare the isokinetic strength of lower extremities in nonpatients and PFPS patients.
Subjects were sampled people who came to Asan Medical Center from September, 1991 to June, 1995. There were 75 nonpatients and 71 PFPS patients from the teens to the seventies. In order to measure the isokinetic peak torque, we examined the both lower extremities of subjects at the speed of 60℃/sec, 180℃/sec and 30℃/sec.
Peak torque was measured and corrected for GET.
The major results are as follows:
1) 20's group of all ages showed the greatest isokinetic extension peak torque and the peak torque significantly decreased in order of 20's, 10's, 30's. 40's, 50's, 60's with increasing angular velocities.
2) 20's group of all ages showed the greatest isokinetic extension peak torque/BW. and the peak torque/BW. significantly decreased in order of 20's, 10's, 30's. 40's, 50's, 60's with increasing angular velocities.
3) In normal group, there were differences in 20's and 60's at flexor peak torque ratio both dominant and non-dominant. In patients group showed over 10% differences caused by PFPS.
