A public data set of human balance evaluations

The data set comprises signals from the force platform (raw data for the force, moments of forces, and centers of pressure) of 163 subjects plus one file with information about the subjects and balance conditions and the results of the other evaluations. Subject’s balance was evaluated by posturography using a force platform and by the Mini Balance Evaluation Systems Tests. In the posturography test, we evaluated subjects during standing still for 60 s in four different conditions where vision and the standing surface were manipulated: on a rigid surface with eyes open; on a rigid surface with eyes closed; on an unstable surface with eyes open; on an unstable surface with eyes closed. Each condition was performed three times and the order of the conditions was randomized among subjects. In addition, the following tests were employed in order to better characterize each subject: Short Falls Efficacy Scale International; International Physical Activity Questionnaire Short Version; and Trail Making Test. The subjects were also interviewed to collect information about their socio-cultural, demographic, and health characteristics.The data set is available at PhysioNet (DOI: 10.13026/C2WW2W) and at figshare (DOI: 10.6084/m9.figshare.3394432).本数据集涵盖163名受试者的测力台（force platform）原始信号数据，包含力、力矩及压力中心（centers of pressure）的原始采集结果；此外还附带一份文件，记录受试者基本信息、平衡测试条件以及其余各项评估结果。受试者的平衡能力通过基于测力台的姿势描记法（posturography）以及迷你平衡评估系统测试（Mini Balance Evaluation Systems Tests）进行评估。在姿势描记法测试中，受试者需分别在四种通过操控视觉条件与站立表面设置的场景下保持静止站立60秒，具体为：睁眼站立于刚性表面、闭眼站立于刚性表面、睁眼站立于不稳定表面、闭眼站立于不稳定表面。每种测试场景均重复执行三次，且受试者间的测试顺序均经过随机化处理。此外，为更全面地刻画每位受试者的特征，本研究还采用了以下评估工具：国际跌倒效能感量表简版（Short Falls Efficacy Scale International）、国际体力活动问卷短卷（International Physical Activity Questionnaire Short Version）以及连线测验（Trail Making Test）。同时，研究人员还对受试者进行了访谈，以收集其社会文化、人口统计学及健康相关特征信息。本数据集可于PhysioNet（DOI: 10.13026/C2WW2W）与figshare（DOI: 10.6084/m9.figshare.3394432）平台获取。
