Abstract

Purpose This study aimed to determine the reliability of the RunScribe™ system to measure kinematic variables of the pelvis during walking and running. Methods In this study, a treadmill protocol was implemented where the participants (n=23) completed 3 sets of 1 minute at 5, 10 and 15 km.h-1. Results All the recorded measurements during walking reported a low reliability with coefficients of variation (CV) greater than 10% in all variables and small-moderate intraclass correlation coefficient (ICC) (< 0.6) in seven out of ten variables. Similarly, the CVs reported in running were greater than 10% except for the maximum angular rate in the obliquity of the pelvis and the vertical oscillation that together with the angular velocity variables showed almost perfect ICCs (> 0.92). Conclusions Therefore, the data obtained suggests that the RunScribe™ system with 3 IMUs does not provide reliable metrics about the kinematics of the pelvis during locomotion (i.e., walking and running).

RunScribe™系统在不同速度下确定骨盆运动变量的可靠性

本研究旨在确定RunScribe™系统在步行和跑步过程中测量骨盆运动学变量的可靠性。方法本研究采用跑步机方案，参与者(n=23)以5、10和15 km.h-1的速度完成3组1分钟的运动。结果所有记录的步行测量结果均为低信度，所有变量的变异系数(CV)均大于10%，10个变量中有7个变量的小-中度类内相关系数(ICC) < 0.6。同样，除了骨盆倾角和垂直振荡的最大角速率以及角速度变量显示几乎完美的ICCs(> 0.92)外，跑步时报告的CVs均大于10%。因此，所获得的数据表明，带有3个imu的RunScribe™系统不能提供有关骨盆运动(即行走和跑步)期间运动学的可靠指标。
