Abstract:
The possibility of gait analyses using moving images was examined using the free software, MediaPipe. As a preliminary experiment for using this software in the rehabilitation field, we attempted a timed up-and-go test and confirmed that detailed ankle trajectories were obtained. In addition, considering the limitations of the camera installation during measurement, we examined the differences in camera position when capturing gait characteristics. As a result, the characteristics captured were almost similar, although some discrepancies were observed between the frontal image and data from the oblique direction. Detection of the ankle angle was possible. However, it is likely that the right ankle data will be calculated to be smaller, regardless of motion limitations, and a motion analysis using gait velocity will require the placement of objects for correction. If free software becomes available for motion analyses, it will be a turning point for the rapid spread of video analyses in the medical and healthcare fields, contributing to the collection of improved data through rehabilitation and daily health management.
