Abstract:	摘要： 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. 其他題名： Sci Rep 出版者： London: Nature Publishing Group UK 出版日期： 2016-12-15 出處： Scientific reports, 2016-12, Vol.6 (1), p.39046, Article 39046 資源來源： ProQuest Open Access Content Collection 版權： The Author(s) 2016 版權： Copyright Nature Publishing Group Dec 2016 版權： Copyright © 2016, The Author(s) 2016 The Author(s) 識別號： ISSN: 2045-2322 識別號： EISSN: 2045-2322 識別號： DOI: 10.1038/srep39046 識別號： PMID: 27976723
