OpenSense model of motor variability for gait

Here we include IMU-driven (OpenSense) and optoelectronic-driven (OpenSim) inverse kinematics from 14 healthy young adults (7 males and 7 females) who performed five 7-minute trials of walking on a treadmill: (i) at preferred speed and with preferred arm swing, (ii) at 70% preferred speed and with preferred arm swing, (iii) at 130% preferred speed and with preferred arm swing, (iv) at preferred speed and with active arm swing, and (v) at preferred speed and with the arms bound to the sides. Models were based on the Rajagopal 2015 full-body model and were modified to lock the toe joints.Our manuscript (https://www.mdpi.com/1424-8220/21/22/7690) reports on the concurrent validity and sensitivity of the OpenSense model for joint angle timeseries, ranges of motion, and several (stride-to-stride) motor variability features from these angles: (a) magnitude of variability, (b) local dynamic stability, (c) persistence of range-of-motion fluctuations, and (d) regularity. <br/><br/>This project includes the following software/data packages: <br/> <ul> <li> <a href="https://simtk.org/frs?group_id=2206#pack_2287">model-data </a> : Optoelectronic and IMU-driven OpenSim model data for five seven-minute gait conditions performed by 14 healthy young participants. </li> </ul>

本研究数据集涵盖了14名健康青年（7名男性和7名女性）在跑步机上进行的五次7分钟行走试验的IMU驱动（OpenSense）和光电驱动（OpenSim）逆向运动学数据：（i）以偏好速度和偏好摆臂方式行走，（ii）以70%偏好速度和偏好摆臂方式行走，（iii）以130%偏好速度和偏好摆臂方式行走，（iv）以偏好速度和主动摆臂方式行走，以及（v）以偏好速度并将双臂束缚于两侧行走。模型基于Rajagopal 2015年的全身模型，并对足趾关节进行了锁定处理。我们的论文（https://www.mdpi.com/1424-8220/21/22/7690）报道了OpenSense模型在关节角度时间序列、活动范围以及从这些角度出发的多个（步态-步态）运动变化特征方面的同时效度和灵敏度：包括（a）变化幅度，（b）局部动态稳定性，（c）运动范围波动持续性，以及（d）规律性。本课题包含以下软件/数据包：（a）模型数据（https://simtk.org/frs?group_id=2206#pack_2287）：14名健康青年在跑步机上进行的五次7分钟步态条件下的光电和IMU驱动OpenSim模型数据。
