The clinical and electrophysiological picture of seven patients with the pronator syndrome is contrasted with other causes of median nerve neuropathy. In general, these patients have tenderness over the pronator teres and weakness of flexor pollicis longus as well as abductor pollicis brevis. Conduction velocity of the median nerve in the proximal forearm is usually slow but the distal latency and sensory nerve action potential at the wrist are normal. Injection of corticosteroids into the pronator teres has produced relief of symptoms in a majority of patients.
将7例旋前圆肌综合征患者的临床和电生理表现与正中神经病变的其他病因进行了对比。一般来说,这些患者在旋前圆肌处有压痛,拇长屈肌和拇短展肌无力。前臂近端正中神经的传导速度通常减慢,但腕部的远端潜伏期和感觉神经动作电位正常。向旋前圆肌内注射皮质类固醇可使大多数患者的症状得到缓解。
