手臂肌肉的异常共激活模式是中风后手臂功能受损的重要原因。我们设计了一个肌电计算机接口（MCI）训练范例，以帮助中风幸存者减少这种异常的共激活。在这里，我们评估了MCI训练对32名慢性卒中幸存者的功能和手臂运动学的影响。我们比较了3个不同组的训练持续时间和等长与基于运动的训练条件的效果。所有组都减少了目标肌肉的异常共激活，并在6周的训练后显示出手臂损伤减少。他们还表现出手臂运动学和功能评分的改善。此外，在训练停止一个月后，尽管大多数收益有所减少，但这些收益仍然存在。这些结果表明MCI训练有望改善中风后手臂功能。
Abnormal co-activation patterns of arm muscles is a substantial cause of impaired arm function after stroke. We designed a myoelectric computer interface (MCI) training paradigm to help stroke survivors reduce this abnormal coactivation. Here, we evaluated the effects of MCI training on function and arm kinematics in 32 chronic stroke survivors. We compared the effects of training duration and isometric vs. movement-based training conditions in 3 different groups. All groups reduced abnormal co-activation in targeted muscles, and showed reduced arm impairment after 6 weeks of training. They also showed improvements in arm kinematics as well as functional scores. Moreover, the gains persisted, though most were reduced, at one month after training stopped. These results suggest that MCI training holds promise to improve arm function after stroke.
