Agreement of Spatiotemporal Gait Characteristics between Gaitboter Gait Analysis System and Noraxon Gait Analysis System / 中国康复理论与实践

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.
