ABSTRACT

Objective To explore the therapeutic effects of isokinetic eccentric exercise (IEE)in patients with knee osteoarthritis. Methods Forty patients, including 70 knees with osteoarthritis, were measured and trained by use of Cybex-6000 and its isokinetic exercise system 3 times per week for 4 weeks. The peak of moment, single largest work, average power and accelerate energy of moment of isokinetic speed in 60?/s、120?/s and 180?/s were measured before and after exercise. The scores of pain and lower limb function were compared before and after IEE. Results The parameters of extensor and flexor groups were significantly increased after exercise, especially the parameters of knee flexors. The scores of pain and lower limb function were also improved. Conclusion IEE could improve effectively the function of knee extensors and flexors in patients with knee osteoarthritis, and relieve the pain.
