A patient with a type of myoclonus produced by somatosensory and photic stimuli was studied electrophysiologically. Jerk-locked averaging showed cortical spikes in association with the spontaneous myoclonus. High amplitude somatosensory evoked potentials and high amplitude visual evoked potentials were observed. Somatosensory and photic stimuli produced 2 or 3 successive electromyographic (EMG) discharges. The time interval from the onset of the preceding EMG discharge to that of the following EMG discharge produced by photic stimulation corresponded to the latency of a long-loop reflex. It also corresponded to the time interval from the onset of the preceding EMG discharge to that of the following EMG discharge produced by somatosensory stimulation. Not only somatosensory but also photic stimuli might excite the loop of a long-loop reflex and cause myoclonic jerks.
对一名由体感和光刺激引发的特定类型肌阵挛患者进行了电生理研究。抽搐锁定平均技术显示，皮层尖峰与自发性肌阵挛相关。观察到高波幅体感诱发电位和高波幅视觉诱发电位。体感和光刺激产生2或3次连续的肌电图（EMG）放电。光刺激产生的前一次EMG放电开始到下一次EMG放电开始的时间间隔与长环反射的潜伏期相对应。它也与体感刺激产生的前一次EMG放电开始到下一次EMG放电开始的时间间隔相对应。不仅体感刺激，光刺激也可能激发长环反射回路并引起肌阵挛性抽搐。
