Brain damage due to stroke often leaves survivors with lateral functional motor deficits. Bimanual rehabilitation of the paretic arm is an active field of research aimed at restoring normal functionality by making use of the complex neural bindings that exist between the arms. In search of an effective rehabilitation method, we introduced a group of post-stroke rehabilitation patients to a set of bimanual motion tasks with inter-manual coupling and phasing. The surface EMG profiles of the patients were compared in order to understand the effect of the motion conditions. The paretic arms of the patients were more strongly affected by the task conditions compared with the non-paretic arms. These results suggest that in-phase motion may activate neural circuits that trigger recovery. Coupling also had an effect on behavior, but the response of patients was divided between those whom coupling helped or hindered.

双手运动对中风后患者肌肉激活的影响

中风引起的脑损伤常常使幸存者留下横向功能性运动障碍。臂臂的双向康复是一项活跃的研究领域，旨在通过利用臂间存在的复杂神经结合来恢复正常功能。为了寻找有效的康复方法，我们向一组卒中后康复患者介绍了一组具有手动耦合和定相功能的双向运动任务。比较了患者的表面肌电图，以了解运动条件的影响。与非paretic手臂相比，患者的paretic手臂受任务条件的影响更大。这些结果表明，同相运动可能会激活触发恢复的神经回路。耦合也会对行为产生影响，
