Data Structure

  • Format: Phase-normalized (150 points per gait cycle)
  • Sampling: Phase-indexed from 0-100%
  • Variables: Standard biomechanical naming convention

Collection Details

Protocol

Standard motion capture protocol was used.

Processing Notes

  • Joint angles computed via OpenSim inverse kinematics
  • Knee angle sign convention converted (source: extension+, output: flexion+)
  • Force plate data missing for S001-S010 (calibration issue)
  • EMG data available in source but not included in parquet conversion
  • Full-body bilateral kinematics available

Files Included

  • converted_datasets/gait120_phase.parquet — Phase-normalized dataset
  • Validation report
  • Conversion script in contributor_tools/conversion_scripts/ga26/
