Abstract

Purpose: To obtain the isokinetic normative data of isokinetic laboratory of department of Rehabilitation Medicine in the normal subjects for those twenties of Korea. Methods: A total of 228 volunteers participated in this study and isokinetic evaluation of knee extensors and flexors at speed $60^{\circ}/sec$ BIODEX System 3 Isokinetic Dynamometer was performed in 128 males and 100 females. Results: In the normal subjects for those twenties, Normative data were presented. Absolute muscle strength of knee-extensors and knee-flexors, Relative muscle strength, bilateral muscle strength deficit, and flexor/extensor strength ratio were presented. Conclusion: Those results expect that it will be available for patients with 20's knee diseases to apply as the basic materials for the muscle function improvement of knee extensors and flexors.
