目的：研究约束摆臂对优选步态转换速度的影响。方法：12位成年人在跑步机上作正常摆臂和约束摆臂两种模式的变速和匀速步态运动实验，采集步态运动数据，建立人体多刚体模型，分析计算走-跑转变（WRT）和跑-走转变（RWT）速度，以及步态时空和运动学参数。结果：正常摆臂的WRT和RWT速度（m?s-1）分别为1.99±0.14和1.89±0.16，约束摆臂的WRT和RWT速度（m/s）分别为1.84±0.14和1.74±0.13，两种摆臂模式下的WRT和RWT速度差异显著。结论：约束摆臂导致优选步态转换速度减小。

Objective: The purpose of this study was to investigate the effect of restricting arm swing on preferred gait transition speed between walking and running. Methods: Twelve adults lovomoted on treadmill with normal and restricted arm swing at constant and variable speed. Human movement was captured. A multi-rigid model was defined to calculate and analyse WRT and RWT speeds, gait spatial-temporal and kinematical parameters. Results: The WRT and RWT speeds (m/s) were 1.99±0.14 and 1.89±0.16 in normal gait, 1.84±0.14 and 1.74±0.13 in gait with restricted arm swing. The difference was significant. Conclusion: Restricting arm swing reduced WRT and RWT speeds.
