Dataset for gait analysis and assessment of fall risk for older adults

This five-part dataset is intended for human gait analysis in an older adult population (37 women and seven men; age 69.98 ± 8.57 years, body mass index 27.71 ± 4.57). Part 1 compromises demographic data for the 44 participants, along with the results of the Short Physical Performance Battery (SPPB) motor function test and the Mini-Mental State Examination (MMSE). We used the MMSE to ensure the participants could understand the experimental protocol instructions. Part 2 presents the anthropometric measurements of the participants. Part 3 shows the results for each item of the Gait component of the Performance Oriented Mobility Assessment (POMA-G). Part 4 contains five files per participant, storing motion-capture data for the lower limb in the Coordinate 3D (C3D) format. These files were generated using a Vicon motion analysis system, consisting of 24 reflective markers and seven cameras (Vantage V5) sampled at 100 Hz. Part 5 contains 26 gait parameters for each C3D file obtained using Nexus 2.9.3.

本数据集共分为五个部分，专为老年人群的人体步态分析而构建（共44名受试者，其中女性37名、男性7名；年龄69.98±8.57岁，身体质量指数27.71±4.57）。第一部分包含44名受试者的人口统计学数据，以及简短体能测试电池（Short Physical Performance Battery, SPPB）运动功能测验与简易精神状态检查（Mini-Mental State Examination, MMSE）的结果。我们采用简易精神状态检查量表以确认受试者能够理解实验流程说明。第二部分展示受试者的人体测量学指标。第三部分呈现功能导向移动能力评估-步态模块（Performance Oriented Mobility Assessment-Gait, POMA-G）各条目对应的测试结果。第四部分为每名受试者提供5个文件，以三维坐标（Coordinate 3D, C3D）格式存储下肢运动捕捉数据。此类文件由Vicon运动分析系统生成，该系统配备24个反光标记点与7台Vantage V5摄像机，采样率为100 Hz。第五部分包含利用Nexus 2.9.3软件导出的每个C3D文件对应的26项步态参数。
