Abstract:
MediaPipe, which enables skeletal analysis using videos of walking subjects without the use of markers, can be easily introduced into rehabilitation sites. Because the video used for analysis is captured from a smartphone or video camera, the viewpoint is obtained from a single camera. Therefore, the skeletal coordinates cannot be recognized during analysis and the obtained coordinates are relative values. In this study, we used data obtained from MediaPipe to calculate stride length, walking speed, knee height change, and ankle angle and compared them with commercially available software. During the measurements, a pseudo-motor restriction was applied by wearing a supporter on the right knee. We found that the presence of motion restriction and various parameters during gait can be obtained by combining the confirmation of gait trajectory with 3D analysis and clarifying the measurement range.
