A 67-year-old woman developed a fixed, flexed posture of the right arm and hand due to a cervical astrocytoma. EMG showed continuous motor unit potential firing at 8 to 15 Hz with an abnormal silent period, presumably due to the loss of local spinal cord inhibitory interneuronal input.
一名67岁女性因颈椎星形细胞瘤出现右臂和手部固定的屈曲姿势。肌电图显示运动单位电位以8至15赫兹持续发放,且静息期异常,推测是由于局部脊髓抑制性中间神经元输入丧失所致。
