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.
手臂肌肉的异常共同激活模式是中风后手臂功能受损的一个重要原因。我们设计了一种肌电计算机接口（MCI）训练模式，以帮助中风幸存者减少这种异常共同激活。在此，我们评估了MCI训练对32名慢性中风幸存者的功能和手臂运动学的影响。我们比较了3个不同组中训练持续时间以及等长训练与基于运动训练条件的影响。所有组在目标肌肉中都减少了异常共同激活，并且在训练6周后手臂损伤有所减轻。他们在手臂运动学以及功能评分方面也有所改善。此外，在训练停止一个月后，这些改善仍然存在，尽管大多数有所减少。这些结果表明，MCI训练有望改善中风后的手臂功能。
