The aim of this study was to compare conduction velocities of motor fibers to smaller and larger muscles and to investigate the advantages and disadvantages of recordings from the gastrocnemius muscle with surface electrodes over the recordings from small foot muscles (interosseous muscles) with needle electrodes in rats. Surface and needle recordings are suitable in measuring the motor conduction velocity of the sciatic (tibial) nerve. It should be noted that the motor velocity measured from the gastrocnemius muscle is higher than the motor velocity elicited from small foot muscles. Surface recordings provide information on the amplitude and duration of M responses.
本研究旨在比较运动纤维在较小和较大肌肉中的传导速度，并探讨在大鼠中使用表面电极记录比目鱼肌（胫神经）与使用针电极记录小足部肌肉（骨间肌）的优势和劣势。表面和针电极记录均适用于测量坐骨（胫）神经的运动传导速度。需要注意的是，从比目鱼肌测量得到的运动速度高于从小足部肌肉引发的运动速度。表面记录提供了 M 反应幅度和持续时间的信息。
