本文是用一种新的振动法探测人的肱二头肌纤维机械传导速度。肌振动仪(SMG)有快速记录微机械反应时的特点,其精度在毫秒以下。 把振动传感器附在二头肌腹正中线或外侧线,刺激电极固定于二头肌,其阴、阳极相隔3cm,远端为阴极,近端为阳极,在正中位和外侧位测量。振动 In this paper, we use a new vibration method to detect the mechanical transmission velocity of human biceps fibers. The Muscle Shaker (SMG) has the feature of quickly recording micromechanical responses with millisecond accuracy. The vibration sensor attached to the midline or lateral line of the biceps abdominis, stimulate the electrode fixed in the biceps, the anion and anode separated by 3cm, the distal cathode, the proximal anode, measured in the median and lateral position. vibration
