Abstract
Patients with osteoarthritic knees are often disabled due to symptoms such as pain, muscle weakness, and impairment of knee proprioception. Previous studies showed that resisted exercises could significantly improve muscular function of those patients and closed kinetic chain exercises have great benefits for joint proprioception. An important determinant in prescribing resisted exercise is weight. Numerous studies have shown that low resistance is a popular method, although the ACSM suggested a higher resistance training program. The purpose of the present study was to compare effects of leg press exercise with different resistance levels in patients with osteoarthritic knees. Method：43 patients with mild to moderate OA knees were randomized into low resistance (n=22) or higher resistance group(n=21). The following variables were assessed before and after the training program for all subjects；(1)Bandi’s functional incapacity score of the osteoarthritic knee.(2)Isokinetic peak torque of knee extensor and flexor；(3)knee joint active-active reposition sense(4)the fastest walking speed of level walking, sponge walking, figure of 8, up and down stairs. An ρevel of .05 was used to test for statistical significance. Results：Knee joint active-active reposition sense improved after training in the higher resistance group. Both groups had significant improvement in the fastest walking speed of all conditions, except for level walking in the higher resistance group. There is a significant increase in the percent change of knee extension torque in the higher resistance group and flexion torque in the low resistance group after 8 weeks of training. Conclusion：The results of this study showed that the leg press exercise is an effective therapeutic exercise for mild to moderate osteoarthritic knees. The low resistance group had significantly better score than the higher resistance group in level walking speed. The higher resistance group had significantly better score than the low resistance group in figure of 8 walking speed and knee joint active-active reposition sense.
