来自于《新英格兰医学杂志》等知名杂志的大量前期研究证实，太极拳能有效提高各类人群的平衡能力。但太极拳提高平衡能力的效应机制研究相对滞后。当前课题以健康人群为切入点，联合应用fMRI技术和NeuroCom平衡功能测试系统，从中枢脑网络和外周平衡力学层面探讨太极拳提高平衡能力的效应机制。以规律练习太极拳一年以上的健康人群为研究对象，以普通运动的健康人群为对照。分别进行fMRI扫描获得功能影像数据，分析表达小脑平衡网络、感觉运动网络和默认模式网络的功能连接差异。同时应用NeuroCom平衡功能测试系统进行外周力学数据测试，表达重心转移曲线和足底冲量分布等动静态平衡力学指标差异。进而以中枢和外周的特征性改变联合Berg量表和TUGT测试等平衡数据进行相关性分析，初步表达太极拳提高平衡能力的中枢与外周关联机制。当前研究将为后期太极拳推广应用于各类患者人群的平衡能力康复提供前期效应机制研究基础。

A large quality of previous studies from the New England Journal of Medicine and other famous journals has indicated that Tai Chi can effectively improve the balance ability of different population. However, the mechanisms of the effect of Tai Chi were not well studied. In the current study, we will focus on healthy subjects. We will try to study the central - peripheral mechanisms of the effects of Tai Chi in improving balance capacity based on fMRI brain functional network and the NeuroCom balance system. Subjects who have continuously practiced Tai Chi for more than 1 year will be included in the study group while healthy subjects matched in gender and age will be included in the control group. All subjects from two groups will undergo fMRI scanning and NeuroCom balance system test. The differences in the cerebellum balance network, sensorimotor network, default mode network will be studied. The differences in the shifting of weight, foot impulse changes and other static and dynamic balance mechanical data will be studied. Then, these changes of brain networks and mechanical data will be totally studied with Berg balance scale and the results of TUGT test. We will conduct correlation analysis to study the central - peripheral mechanisms of the effects of Tai Chi in improving balance capacity. The results of the current study will provide basic mechanisms data for the popularization and application of Tai Chi in improving the balance ability in different patients.
