声音的精确定时在音乐表演和聆听中都是至关重要的。事实上，听有节奏的声音序列不仅激活了听觉系统，也激活了感觉运动系统。以前，我们展示了神经β波段振荡（15-30 Hz）对涉及这种运动协调的时间处理的重要性。因此，我们假设运动康复训练结合音乐播放将刺激和增强中风患者的大脑-运动互动。我们检查了三个慢性病人谁接受音乐支持治疗后，施耐德实践的协议。对于轻瘫或非轻瘫的手来说，在被动聆听节拍器期间和在有或没有节拍器的情况下敲击手指期间，神经磁β频带活动非常相似，这表明β调制的共同机制。在听力任务中，音调开始后β下降的幅度在训练后时间点更明显，并伴随着手臂和手部技能的改善。目前的病例数据提供了深入了解音乐制作和有节奏的听觉刺激康复的神经基础。
Precise timing of sound is crucial in music for both performing and listening. Indeed, listening to rhythmic sound sequences activates not only the auditory system but also the sensorimotor system. Previously, we showed the significance of neural beta-band oscillations (15-30 Hz) for the timing processing that involves such auditory-motor coordination. Thus, we hypothesized that motor rehabilitation training incorporating music playing will stimulate and enhance auditory-motor interaction in stroke patients. We examined three chronic patients who received Music-Supported Therapy following the protocols practiced by Schneider. Neuromagnetic beta-band activity was remarkably alike during passive listening to ametronome and during finger tapping, with or without the metronome, for either the paretic or nonparetic hand, suggesting a shared mechanism of the beta modulation. In the listening task, the magnitude of the beta decrease after the tone onset was more pronounced at the posttraining time point and was accompanied by improved arm and hand skills. The present case data give insight into the neural underpinnings of rehabilitation with music making and rhythmic auditory stimulation.
