Abstract

Purpose: The aim of this study was 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.

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™ 系统确定不同速度运动时骨盆运动变量的可靠性。

目的：本研究旨在确定 RunScribe™ 系统测量步行和跑步时骨盆运动学变量的可靠性：在这项研究中，参与者（n = 23）在跑步机上以 5、10 和 15 公里/小时的速度完成了 3 组 1 分钟的测量：结果：在步行过程中记录的所有测量值的可靠性都很低，所有变量的变异系数（CV）都大于 10%，类内相关系数（ICC）为 0.92（中小值）：因此，获得的数据表明，带有 3 个 IMU 的 RunScribe™ 系统无法提供运动（即行走和跑步）过程中骨盆运动学的可靠指标。
