我们描述了一位35岁的女性，她表现出右手移动手指疼痛的综合征。8个月后，她出现了类似的手指运动和左手不适。她有手部外伤史和右侧复发性肩关节脱位。运动学肌电图显示，双手的手指运动有一个共同的中央振荡器。脊髓α运动神经元兴奋性、相互抑制和Renshaw细胞抑制的电生理评估未显示任何异常。体感诱发电位测试显示，左侧体感皮层记录的N20电位明显衰减；配对经皮质磁刺激左运动皮层提示皮层易化失败。数据表明，该患者负责手指运动的中央振荡器位于脊髓水平上方。
We describe a 35‐year‐old woman who presented with the syndrome of painful hand–moving fingers on the right side. Eight months later, she developed similar finger movements and hand discomfort on the left side. She had a history of hand trauma and recurrent shoulder dislocation on the right side. Kinesiologic electromyography suggested a common central oscillator for finger movements in both hands. Electrophysiological assessment of spinal alpha motor neuron excitability, reciprocal inhibition, and Renshaw cell inhibition failed to show any abnormalities. Somatosensory evoked potential test showed marked attenuation of N20 potential recorded from the left somatosensory cortex; paired transcortical magnetic stimulation of the left motor cortex suggested failure of cortical facilitation. The data suggest that the central oscillator responsible for finger movements is located above the spinal cord level in this patient.
