頸髄症における上肢運動機能の経時的変化 -術前・術後3ヶ月までの変化-

摘要

We examined the time series change in upper extremity motor function from pre-operation until a postoperative three months in cervical myelopathy patients. An investigated element was on five sides of the synthetic upper extremity motor function (STEF) as to the spinal cord deficiency symptom (FES), the repetitive movement speed (ten-second test), the muscle power (power grip and the pinch power), the elemental movement (separative function : FFT) of the fingers. And, which element improved in which time, or it was examined. Cervical cord deficiency symptom and a repetitive movement speed, the elemental movement of finger (separative movement) improved remarkably by a one month postoperatively, and then did not improve any further. On the other hand, bimanual intrinsic muscle power and the synthetic upper extremity motor function improved soon after the operation, and continued to improve. There was no change in extrinsic muscle power in until one month postoperatively. But, a remarkable change was shown after that until three months postoperatively.
