摘要

磁惯性测量单元(mimu)在人体运动分析中获得越来越多的共识。然而，临床步态分析等应用需要可靠，可重复和准确的步态参数测量，达到mimu不容易实现的水平。我们指出了在使用基于mimi的h -步态系统时遇到的一些具体的技术挑战，涉及到1)校准程序和2)踝关节运动曲线的高度分散。我们描述了如何解决这些问题:1)从手动转向半自动校准程序;2)在脚上获得最佳的mimu定位。关节运动学结果与标准机电系统(STEP32)获得的结果进行了验证。

Technical challenges using magneto-inertial sensors for gait analysis

Magneto-Inertial Measurement Units (MIMUs) are gathering an increasing consensus in human motion analysis. However, applications such as clinical gait analysis require reliable, repeatable and accurate measurements of gait parameters up to a level that it is not easily achievable with MIMUs. We pointed out some specific technical challenges that we encountered in the use of the MIMUs-based H-gait system, pertaining to 1) calibration procedure and 2) high dispersion of ankle joint kinematic curves. We described how we solved these issues: 1) shifting from a manual to a semi-automatic calibration procedure and 2) obtaining an optimal MIMUs positioning on the foot. Joint kinematic results were validated against those acquired with a standard electromechanical system (STEP32).
