• IMU data are provided in 170 subfolders named IMU_S[subjectID]_[speed].
• Missing folders include: S2_0.75, S2_1, S3_0.75, S3_1, S24_0.5, S24_0.75, S24_1.
• Each folder contains 18 (.csv) files corresponding to segment and joint-level outputs, including orientations (quaternions), segment positions and velocities, accelerations, angular velocities, and joint angles following ISB conventions.
• Joint angle data are available for the spine, head, upper and lower limbs, and major joints (shoulder, elbow, wrist, hip, knee, ankle, ball of foot).
The IMU data are organized as per-subject, per-speed folders.
If this folder appears compressed, please extract to restore the hierarchy (IMU_S1_0.5/, IMU_S1_0.75/, …).
