In this study, the scanning EMG technique was implemented to investigate electrophysiological cross-sections of the motor unit (MU) territories in healthy volunteers and in subjects with juvenile myoclonic epilepsy and spinal muscular atrophy. Measurements were taken intramuscularly by means of two concentric needle electrodes from biceps brachialis muscles. 3-D maps of the MU territories were plotted for each MU to determine the lengths of MU cross-section and the maximum amplitudes of each MU. There was evidence of a preponderance of large MUs in patients with juvenile myoclonic epilepsy.
在本研究中，采用扫描肌电图技术来研究健康志愿者、青少年肌阵挛性癫痫患者和脊髓性肌萎缩症患者运动单位（MU）区域的电生理横断面。通过两根同心针电极从肱二头肌进行肌肉内测量。为每个运动单位绘制其区域的三维图，以确定运动单位横断面的长度和每个运动单位的最大振幅。有证据表明青少年肌阵挛性癫痫患者中大型运动单位占优势。
