Abstract
Background and purpose: High intensity open chain exercise increases the severity of symptoms in osteoarthritis knees. In closed-chain condition, the joints bear body weight and their proprioceptive receptors fire actively and frequently more than open-chain does. The results of earlier serial researches indicate that the proprioception under closed-chain testing model is more accurate than it under open-chain model. However, the information is not sufficient to answer that whether or not the training effect of closed-chain exercise is better than that of open-chain. Therefore, we hypothesize that the effectiveness of exercise in open-chain and closed-chain model could be different in knee disorders (i.e., osteoarthritis). The purpose of this study is to compare the training effect of closed-chain and open-chain exercise program. Methods: Including 61 subjects from NTU hospital and randomized into open chain group (26 subjects), closed chain group (19 subjects) and control group (16 subjects). The evaluation measures to be used are (1) third part of WOMAC functional score, (2) walking speed in 3 routes (straight line, up/down stairs, sponge and figure eight). (3) knee joint reposition sense (proprioception) and (4) isokinetic strength. Result: training groups (open chain and closed chain) improved significantly in all evaluation measures, except walking on sponge and knee joint reposition sense in open chain group. The sponge and figure of eight walking speed, knee joint reposition sense, and flexor muscle strength in closed chain exercise has more effects than open chain. Conclusion: closed chain and open chain exercise training have the same effectiveness in several evaluation measures. But the closed chain exercise training are better than open chain in peoprioceptive related performance such as sponge walking, figure of eight walking and strength of knee flexor.
