ABSTRACT

Objective: To demonstrate that the isokinetic exercise is better than the isotonic to increase the knee’s flexor-extensor muscles physical capacity. Methods: Observational, analytical, prospective, longitudinal, on a sample of 40 patients, 40 to 65 years old, both sexes, with clinical and radiographic knee osteoarthritis grade I-IV. An initial evaluation was done to measure the isokinetic torque, total work, power and fatigue of the flexor-extensor muscles in both knees. The patients were divided into 2 groups of 20 people; one group received an isokinetic exercise program and the other group an isotonic exercise program, both in 30 treatment sessions. At the end, the initial parameters were evaluated and the results were analyzed using the SPSS v.10 statistical package with the Student’s t test (significance p ‹ 0.05). Results: Significant improvement (p ‹ 0.05) was found in peak torque with 90±/seg of angular speed, total work, mean power and fatigue with 180±/seg in both exercise programs, without significant differences between them. Conclusion: Both exercise programs improve the isokinetic parameters in flexor and extensor muscles in patients’ knees with osteoarthritis without significant difference between them.
