Abstract:
MediaPipe, which enables skeletal analysis utilizing videos of walking subjects without markers, can be easily introduced into rehabilitation sites. The viewpoint is obtained from a single camera because the video utilized for analysis is captured from a smartphone or video camera. Therefore, the skeletal coordinates cannot be recognized during analysis, and the obtained coordinates are relative values. Here, we employed data obtained from MediaPipe to calculate stride length, walking speed, knee height change, and ankle angle and compared them with commercially available software. A pseudo-motor restriction was applied during the measurements 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. In addition, patients undergoing rehabilitation were asked to wear walking aids, and the walking patterns before, during, and after wearing them were analyzed with MediaPipe to confirm the effectiveness of the walking-assisted aid attachment.
