Parkinson's disease (PD) affects gait and postural stability. Tai Chi (TC) is recommended for PD for management of the condition, however biomechanical understanding to its effects on gait and postural stability is limited. This study aimed to examine the effects of an online 12-week biomechanical-based TC intervention on gait and posture in people with PD. Fifteen individuals in early-stage PD were recruited (Hoehn & Yahr stages 1-2). The TC intervention program was 60 min session, three times weekly for 12 weeks. The pre- and post-intervention test in obstacle crossing, timed-up-and-go (TUG) test, and single leg standing (SLS) with eyes open (EO) and closed (EC) were conducted. Gait speed, crossing stride length, clearance height of the heel and toe, anterior-posterior (AP) and medial-lateral (ML) displacement and velocity of the center of mass (COM) and separation of the COM-center of pressure (COP) were analyzed. The participants significantly improved their pre-vs. post-TC intervention performance on TUG test ( = 0.002). During obstacle crossing, the participants significantly increased crossing stride length of the trailing foot, increased AP COM displacement and decreased ML COM-COP separation ( < 0.05); the maximal dorsiflexion angle of the leading limb significantly increased and maximal plantarflexion angle of the trailing limb significantly decreased ( < 0.05). A 12-week biomechanical-based online TC training was effective towards improvement of gait and postural stability among people in the early-stage of PD. The TC program and online training could be applied for management of PD.
帕金森病（PD）会影响步态和姿势稳定性。太极拳（TC）被推荐用于帕金森病的病情管理，然而，对于其对步态和姿势稳定性影响的生物力学理解有限。本研究旨在探讨基于生物力学的为期12周的在线太极拳干预对帕金森病患者步态和姿势的影响。招募了15名早期帕金森病患者（Hoehn & Yahr分期1 - 2期）。太极拳干预方案为每次60分钟，每周三次，共12周。在干预前后进行了过障碍测试、计时起立行走（TUG）测试以及睁眼（EO）和闭眼（EC）单腿站立（SLS）测试。分析了步态速度、跨步步幅长度、足跟和足尖的离地高度、前后（AP）和内外侧（ML）方向的质心（COM）位移和速度以及COM与压力中心（COP）的分离情况。参与者在TUG测试中干预前后的表现有显著改善（ = 0.002）。在过障碍过程中，参与者后脚的跨步步幅长度显著增加，AP方向的COM位移增加，ML方向的COM - COP分离减小（ < 0.05）；前肢的最大背屈角度显著增加，后肢的最大跖屈角度显著减小（ < 0.05）。为期12周的基于生物力学的在线太极拳训练对改善早期帕金森病患者的步态和姿势稳定性有效。太极拳方案和在线训练可用于帕金森病的管理。
