Abstract

Involuntary movements in a patient with Sydenham's chorea were usually characterised by bursts of EMG activity lasting more than 100 ms, occurring asynchronously in antagonist muscles. The "hung-up" knee jerk was a choreic movement induced by the tendon tap. Exaggerated voluntary movements were produced with EMG burst longer than normal.

摘要

患有 Sydenham 舞蹈病的患者的不自主运动通常表现为肌电图活动爆发持续超过100毫秒,在拮抗肌中异步发生。“挂起”膝跳反射是由肌腱叩击诱发的舞蹈样运动。夸张的自主运动产生时肌电图爆发比正常情况更长。
