The activation times for trunk and leg muscles were examined in normal and left hemiplegic subjects who raised their right arms at different velocities in self-paced or reaction time conditions. Activity in these postural muscles preceded arm displacement, and they were activated in a similar sequence during all types of rapid movements. The presence and sequencing of associated postural adjustments were more variable during slow movements.
在正常受试者和左侧偏瘫受试者中,研究了他们在自定步速或反应时间条件下以不同速度举起右臂时躯干和腿部肌肉的激活时间。这些姿势肌肉的活动先于手臂移动,并且在所有类型的快速运动中它们以相似的顺序被激活。在缓慢运动期间,相关姿势调整的存在和顺序变化更大。
