Data belonging to the paper: Effect of perturbation timing on recovering whole-body angular momentum during very slow walking

This dataset contains gait data used to produce the results of the paper (currently under review at Human Movement Science): 'Effect of perturbation timing on recovering whole-body angular momentum during very slow walking'. An extensive description of the methods can be found in the paper. 10 healthy participants walked on a treadmill while receiving perturbations of the whole body angular momentum at the moment of toe off right, mid-swing and heel strike right. Meanwhile ground reaction forces and optical motion capture was recorded. The dataset contains the following measures: whole body angular momentum, centre of pressure position, horizontal ground reaction force, moment arm of the ground reaction force with respect to centre of mass, the interaction forces between the motors applying the perturbations and the participants, and the joint moments of the left and right hip, knee and ankle.<br>

本数据集包含用于生成某篇已投稿至《Human Movement Science》（目前处于审稿阶段）的论文结果的步态数据（gait data），该论文标题为《扰动时机对极慢步行过程中全身角动量恢复的影响》。方法的详细说明可参阅该论文。
10名健康受试者在跑步机上行走，期间于右足离地、摆动中期及右足足跟触地时刻接受针对全身角动量的扰动，同时采集地面反作用力（ground reaction force）与光学运动捕捉（optical motion capture）数据。
本数据集包含以下测量指标：全身角动量、压力中心位置（centre of pressure position）、水平地面反作用力、相对于质心（centre of mass）的地面反作用力力臂、施加扰动的电机与受试者之间的相互作用力，以及左右侧髋、膝、踝关节的关节力矩。
