Data belonging to the paper: Sagittal-plane balance perturbations during very slow walking: Strategies for recovering linear and angular momentum

This dataset contains the data used to produce the results of the paper: 'Sagittal-plane balance perturbations during very slow walking: Strategies for recovering linear and angular momentum'. 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 linear or angular momentum at the moment of toe off right. Meanwhile ground reaction forces and optical motion capture was recorded. The dataset contains the following measures: whole body angular momentum, whole body centre of mass velocity, 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 hip and ankle.

本数据集包含用于生成论文《极慢行走过程中矢状面平衡扰动：线性与角动量恢复策略》（Sagittal-plane balance perturbations during very slow walking: Strategies for recovering linear and angular momentum）研究结果的相关数据。该研究的方法细节可详见该论文。10名健康受试者在跑步机上行走，并于右脚离地时刻接受全身线性动量或角动量扰动。实验过程中同步记录地面反作用力（ground reaction force）与光学运动捕捉（optical motion capture）数据。本数据集涵盖以下测量指标：全身角动量、全身质心（centre of mass）速度、压力中心（centre of pressure）位置、水平地面反作用力、相对于质心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，以及髋关节与踝关节的关节力矩。
