Data set of "Smart" Brace Validation Study

This data set was collected to validate a 'smart' knee brace with an IMU embedded on the thigh and shank area against a reference motion capture system (Vicon). There were 10 participants total and each participant came into the lab for 2 sessions, each on separate days. For each session, participants completed three trials of 2-minute treadmill walking at their preferred walking speed, three trials of 15 squats to parallel, three trials of 10 sit-to-stand on a chair that was about knee level, three trials of 15 total alternating lunges, and three trials of 2-minute treadmill jogging at their preferred speed, all in that order. 10 squats and 10 lunges were done for some participants' first sessions, but then did 15 squats and lunges in the second session (a .txt file will be included for each participants' session to specify). This dataset only contains the IMU data.本数据集旨在验证一款搭载惯性测量单元（IMU, Inertial Measurement Unit）的智能膝关节支具，该支具的IMU分别布设于大腿与小腿区域，对照参考运动捕捉系统（Vicon）开展性能验证。本次研究共招募10名受试者，每名受试者分两日前往实验室完成两次测试，两次测试分别在不同日期进行。 每次测试中，受试者依次完成以下流程：以自身偏好步行速度进行2分钟跑步机步行，共完成3个试次；完成15次深蹲至大腿与地面平行，共3个试次；在高度约为膝盖高度的椅子上完成10次坐站转换动作，共3个试次；完成15次交替弓步，共3个试次；以及以自身偏好慢跑速度进行2分钟跑步机慢跑，共3个试次。所有测试流程严格按照上述顺序执行。 部分受试者在首次测试中仅完成10次深蹲与10次交替弓步，而第二次测试则完成15次深蹲与15次交替弓步；每名受试者的对应测试详情将通过其测试场次的.txt文件予以说明。 本数据集仅包含IMU采集的原始数据。
