恒定速率的重复运动需要整合内部时间计数和运动神经网络。以前的研究已经证明，人类可以自动跟踪短时间（自动计时），但需要更多的认知努力来跟踪或估计长时间。在这项研究中，我们研究了感觉运动振荡活动的健康受试者和慢性中风患者时，受试者进行重复的手指运动。我们发现，α和β振荡活动的运动调制的变化减少的运动频率的增加，在正常人的手指抬起和非麻痹的手在脑卒中患者，而在不同的运动速率的paretic-hand运动没有发现差异。非轻瘫手和轻瘫手的振荡活动之间的显着差异，可能意味着更高的认知努力，以执行快速重复动作轻瘫手。快速重复运动中的感觉运动振荡反应可能是脑卒中患者运动功能恢复的一个指标。
Repetitive movements at a constant rate require the integration of internal time counting and motor neural networks. Previous studies have proved that humans can follow short durations automatically (automatic timing) but require more cognitive efforts to track or estimate long durations. In this study, we studied sensorimotor oscillatory activities in healthy subjects and chronic stroke patients when subjects were performing repetitive finger movements. We found the movement-modulated changes in alpha and beta oscillatory activities were decreased with the increase of movement rates in finger lifting of healthy subjects and the non-paretic hands in stroke patients, whereas no difference was found in the paretic-hand movements at different movement rates in stroke patients. The significant difference in oscillatory activities between movements of non-paretic hands and paretic hands could imply the requirement of higher cognitive efforts to perform fast repetitive movements in paretic hands. The sensorimotor oscillatory response in fast repetitive movements could be a possible indicator to probe the recovery of motor function in stroke patients.
