摘要：The purpose of this study was to elucidate the effectiveness of the experimental training session, which consisted of 8-weeks leg strength endurance training, 8-weeks detraining, and 8-weeks retraining, in a stroke patient with hemiparesis. Three sets of the leg strength endurance training which was composed of consecutive 50 knee extension at the angular velocity of 180° /sec were performed three times a week. The results obtained were: 1) Muscle endurance in both affected and unaffected sides was improved after the session; particularly, the improvement tended to be comparatively prominent in the 4th weeks of the training. 2) During 8-weeks detraining, the muscle strength of unaffected side was maintained, whereas that of affected side showed remarkable deterioration. 3) It was found that the subject kept a very high level of gait amount during detraining, which implies that the walking in which the unaffected side was used dominantly may contribute to keeping the muscle strength to some extent. 4) During 8-weeks retraining, led the temporarily decreased muscle strength of both affected and unaffected sides to some improvement. In 50 trials of muscle out put, the measured values of peak torque of affected muscles became constant after thetraining. It follows from what has been elucidated that muscle endurance of lower extremities of the stroke patient with hemiparesis was improved by the training of relatively high speed. It was further suggested that the neurotic control can possibly be improved by retraining.
