Abstract:
The use of free software in motion analyses in the medical and healthcare fields could contribute to the collection of improved data through rehabilitation and daily health management. The possibility of gait analyses using moving images is examined using the free software, MediaPipe. As a preliminary experiment for applying this software in the rehabilitation field, we attempt a timed up-and-go test and obtain detailed ankle trajectories. Additionally, considering the limitations of the camera installation during measurement, we examine the differences in the camera position when capturing the gait characteristics. Consequently, the characteristics captured were almost similar, although some discrepancies were observed between the data from the front and oblique directions. The detection of the ankle angle was possible. However, a motion analysis using the gait velocity will be required for the correct placement of objects. We analyzed the data obtained from the application of the Orthobot, a gait aid device, for the measurement of gait. The detection of the differences in gait before and after the application of the Orthobot would significantly contribute to the gait assessment. The data were compared with those obtained using ORPHE ANALYTICS. Because MediaPipe only provides relative coordinate values for 33 different target body parts, data interpretation requires correction. However, it proved to be a tool that provided a lot of information by allowing researchers to incorporate the necessary formulas.
