腕隧道症候羣的電學診斷

The Electrodiagnosis of Carpal Tunnel Syndrome

摘要


腕隧道症候群是一般電學診斷檢查室最常見的一種壓迫性神經病變,由於電學診斷可提供對神經生理變化上的了解,對此病的診斷有很大幫助,另外在治療上也可提供一個重要的指標,並可作為其預後的評估方法。 電學診斷應用於腕隧道症候群的方法很多,大多以神經傳導檢查正中感覺神經手指至腕部及手掌至腕部的傳導時間與傳導速度,及運動神經傳導時間等;另外以針肌電圖也可測其病變引起的神經與肌肉變化,本文例舉各種電學診斷方法,並以台大醫院復健科124位腕隧道症候群患者所得結果及參考國外學者的研究結果來探討其在臨床上的應用。

Carpal tunnel syndrome is the most common entrapment neuropathy in the electromyographic laboratories. Many techniques of motor and sensory nerve conduction, anomalous innervation and needle electromyography are reviewed. The results of electromyographic testing of 124 patients with carpal tunnel syndrome in the Department of Physical Medicine and Rehabilitation of National Taiwan University Hospital are realized and compared with the results from foregin studies. The existing methods of electrodiagnosis are avalable and objective in the detection of carpal tunnel syndrome, though they should be adjusted with the patient's clinical symptoms and signs. The treatment of carpal tunnel syndrome depends on the clinical conditions of the patient. Operation with neurolysis may be carefully selected and evaluated by electrodiagnosis postoperatively.
