About

The purpose of this study was to assess the Openpose reliability to measure kinematics and spatiotemporal gait parameters and to evaluate the minimum technical requirements. This analysis used video and optoelectronic motion capture simultaneously recorded. We assessed more of 20 subject with different motor gait impairments

Full description

Marker-based Optical motion tracking is the gold standard in gait analysis, but today, markerless solutions are growing rapidly. Treatment of physical impairments could improve if supported with reliable motion capture. Moreover, the use of markerless technology offers numerous advantages for working with pediatric populations under various conditions. In this paper, we assess the Openpose reliability to measure kinematics and spatiotemporal gait parameters and to evaluate the minimum technical requirements., in a population of children with and without gait impairments. Validating markerless methods can open the way for new motion capture techniques and enhance the accessibility of kinematic measurements and improve the treatment of physical impairments.
