The objective of this study was to estimate the number of motor units in 5 muscles from healthy individuals using the MScanFit program based on compound muscle action potential (CMAP) scan recordings. The examined muscles included first dorsal interosseous (FDI), abductor pollicis brevis (APB), abductor digiti minimi (ADM), second lumbrical (SL), and abductor hallucis (AH). CMAP scans were recorded from a total of 24 healthy participants. Motor unit number estimation (MUNE) values were derived from the MScanFit program. The average MUNE was 136.1 ± 31.1 (mean ± standard deviation) for the FDI, 134.9 ± 37.4 for the APB, 127.3 ± 32.3 for the ADM, 39.6 ± 8.3 for the SL, and 143.9 ± 28.9 for the AH muscles. Findings of the study provide useful information of the MScanFit MUNE for the examined muscles of healthy subjects from a single center.
本研究的目的是使用基于复合肌肉动作电位（CMAP）扫描记录的MScanFit程序，估计健康个体5块肌肉中的运动单位数量。所检查的肌肉包括第一背侧骨间肌（FDI）、拇短展肌（APB）、小指展肌（ADM）、第二蚓状肌（SL）和拇展肌（AH）。共对24名健康参与者进行了CMAP扫描记录。运动单位数量估计（MUNE）值由MScanFit程序得出。FDI的平均MUNE为136.1±31.1（平均值±标准差），APB为134.9±37.4，ADM为127.3±32.3，SL为39.6±8.3，AH肌肉为143.9±28.9。该研究结果为来自单一中心的健康受试者所检查肌肉的MScanFit MUNE提供了有用信息。
