偏癱患者接受上肢負重運動對於腕部神經之立即影響

Abstract

The aim of this study was to investigate the immediate effects of upper extremity loading exercises on conduction in the median and ulnar nerves in the wrists of hemiplegic patients. Seventeen hemiplegic patients without past history of carpal tunnel syndrome or other confounding diseases and seventeen healthy and physically-matched control subjects were recruited. Nerve conduction tests of the median and ulnar nerves were performed in both arms of patients and healthy controls before and after a set of 30-minute bilateral loading exercise. Significant reductions (p＜0.05) were found in median compound motor action potential, median sensory nerve action potential and ulnar compound motor action potential in the hemiplegic side as compared with control subjects. These differences may be affected by median nerve circulation disturbance after prolonged wrist flexion on the hemiplegic side, and atrophic changes of peripheral nerve after upper motor neuron injuries. A further decrease in median sensory nerve conduction velocity was also observed after bilateral loading exercises on the hemiplegic side, perhaps because of demyelinating changes in the median nerve after direct compression of the carpal tunnel. These findings suggest that maintaining wrist range of motion and using protective appliances are essential when conducting upper limb exercise training in hemiplegic patients.
