Objective To evaluate the effects of rehabilitation training on muscle strength and exercise toleranee in hemodialysis patients with muscle atrophy.Methods Nine hemodialysis patients with muscle atrophy because of end renal failure were recruited in this study. A structured exercise program(90 minutes a sedssion.3 sessions a week)was administered to all the subjects for 6 month.Immediately before and at the end of the exercise programme,the muscle strength of the lower limbs,the motor conduction velocity of the peroneal nerve and maximal oxygen consumption of the patients were examined. Results It was shown that all the patients had impaired exercise capacity,weakend muscle strength and slowed nerve conduction velocity before rehabilitation training.After the exercise programme,the patients' exercise capacity as reflected by the maximal oxygen consumption and exercise time was significantly increased.The muscle strength and the motor nerve conduction velocity were significantly increased.Conclusions Muscle atrophy in hemodialysis patients results in poor exercise tolerance, but rehabilitation exercise programme improves amyotrophy and therefore has beneficial effects on the patient's overall work performance.
