摘要/Abstract

摘要： 目的

探讨Gaitboter与Noraxon步态分析系统时空参数的一致性。

方法

2019年2月至4月，选取35例健康成年人，分别应用Gaitboter与Noraxon步态分析系统进行步态测试，记录其站立相及迈步相时间比例、跨步长、步频、步速、足偏角等时空参数，采用组内相关系数(ICC)和Bland-Altman散点图评定两种步态分析系统的一致性及差异。

结果

两种步态分析系统测试所得时空参数的信度较好(ICC 0.691~0.835)。Bland-Altman法一致性检验结果显示，两种步态分析系统测试所得时空参数间的一致性较好。

结论

Gaitboter与Noraxon步态分析系统测试所得时空参数一致性较好，可进一步在临床试用以观察测试效果。

Abstract: Objective

To assess the agreement between measurements of spatiotemporal gait characteristics made with Gaitboter and Noraxon gait analysis systems.

Methods

From February to April, 2019, 35 healthy adults were recruited to participate in gait analysis using Gaitboter and Noraxon gait analysis apparatuses, respectively. Stance phase, swing phase, stride length, cadence, velocity and toe out were recorded and computed. Intraclass correlation coefficients (ICC) and Bland-Altman plots were used to evaluate the agreement between the two gait analysis systems.

Results

There was a good reliability in spatiotemporal gait characteristics between two gait analysis systems (ICC 0.691 to 0.835). Bland-Altman plots also showed good agreement.

Conclusion

The measurements of temporal and spatial parameters with Gaitboter and Noraxon gait analysis systems yield acceptable agreement, and further study needs to be conducted on the validity of the Gaitboter gait analysis system.

Key words: agreement, gait analysis system, temporal and spatial parameters
