Diabetic subjects completed a series of rapid, goal-directed arm movements under two conditions of unexpected external loading. Evaluation of electromyographic (EMG) patterns revealed that cocontraction and triphasic activity were predominantly associated with inertial and spring loading, respectively. During inertial load responses some EMG patterns indicated a modified cocontraction pattern. Response accuracy was unaffected by type of load but movement time was greater for the inertial load condition.
糖尿病患者在两种意外外部负荷条件下完成了一系列快速、目标导向的手臂运动。肌电图（EMG）模式评估显示，共同收缩和三相活动分别主要与惯性负荷和弹性负荷相关。在惯性负荷反应期间，一些EMG模式显示出一种改变的共同收缩模式。反应准确性不受负荷类型的影响，但惯性负荷条件下的运动时间更长。
