Abstract

Objective

The AlterG treadmill provides bodyweight support and gait data for rehabilitation. Clinicians often use spatiotemporal gait parameters to assess a patient’s progress during rehabilitation; therefore, the validity and reliability of these metrics are very important. This study aimed to assess the agreement and reliability of the spatiotemporal gait metrics measured by the Stride Smart system in the AlterG treadmill compared to the Xsens motion capture system during walking at different bodyweight support conditions.

Methods

17 healthy adults walked on an AlterG treadmill at 3 km/h and 4 km/h at 4 bodyweight conditions (100, 75, 50, 25 %) while wearing Xsens sensors on the lower body, repeating this session 7.0 ± 0.7 days later. Gait metrics were calculated using the Xsens motion cloud software and the Stride Smart system. Agreement and between-session reliability for the Stride Smart Gait metrics were assessed.

Results

Stride Smart gait metrics cadence, step length and stance time were reliable (ICC ≥ 0.621) and showed good agreement (r ≥ 0.602) for 100 and 75 % bodyweight, but not for 50 and 25 % bodyweight compared to the Xsens system.

Conclusions

Therefore, clinicians should only use gait metrics at ≥ 75 % bodyweight to assess progress in rehabilitation when using the Stride Smart system on the AlterG treadmill.

与Xsens相比，在AlterG跑步机上使用跨步智能系统测量的步态指标的一致性和可靠性。

目的：AlterG跑步机为康复提供体重支持和步态数据。临床医生经常使用时空步态参数来评估患者在康复过程中的进展；因此，这些指标的有效性和可靠性是非常重要的。本研究旨在评估在不同体重支撑条件下，在AlterG跑步机上，Stride Smart系统与Xsens运动捕捉系统测量的时空步态指标的一致性和可靠性。方法：17名健康成人在AlterG跑步机上以3 km/h和4 km/h的速度在4种体重条件下（100、75、50、25 %）行走，下体佩戴Xsens传感器，7.0 ± 0.7天后重复该过程。使用Xsens运动云软件和Stride智能系统计算步态指标。评估跨步智能步态指标的一致性和会话间可靠性。结果：与Xsens系统相比，Stride Smart步态指标节奏、步长和站立时间是可靠的（ICC≥0.621），并且在体重为100和75% %时显示出良好的一致性（r ≥ 0.602），但在体重为50和25% %时则不一致。结论：因此，当在AlterG跑步机上使用Stride Smart系统时，临床医生应该只使用体重≥ 75 %的步态指标来评估康复进展。

期刊介绍： The Foot is an international peer-reviewed journal covering all aspects of scientific approaches and medical and surgical treatment of the foot. The Foot aims to provide a multidisciplinary platform for all specialties involved in treating disorders of the foot. At present it is the only journal which provides this inter-disciplinary opportunity. Primary research papers cover a wide range of disorders of the foot and their treatment, including diabetes, vascular disease, neurological, dermatological and infectious conditions, sports injuries, biomechanics, bioengineering, orthoses and prostheses.
