Gait120 — Human Locomotion & EMG (cleaned subset)

MuscleMimic paper: Towards Embodied AI with MuscleMimic: Unlocking full-body musculoskeletal motor learning at scale.

Per-subject electromyography (EMG), joint kinematics, motion-capture marker data and SMPL motion fits for 120 participants performing level walking.

Participants

120 participants, all male, organised as two age cohorts (subject ID is confounded with age):

Cohort	Subjects	N	Mean age	Age range
Young (YG)	S001–S060	60	~23 yr	20–25
Older (OG)	S061–S120	60	~47 yr	40–59

Aggregate (n=120): age 35.4 ± 12.9 yr · height 1.73 ± 0.06 m · body mass 74.2 ± 12.5 kg. Per-subject values are in subject_metadata.csv (adds an age_group column) and in the original Subject_Demographics.xlsx / Anthropometric_Data_Participants.xlsx.

Directory structure

Subjects are grouped in blocks of ten:

Gait120_001_to_010/
  S001/
    EMG/ConvertedData.mat                         # interpolated EMG per trial/step (LevelWalking)
    JointAngle/LevelWalking/TrialXX/stepYY.mot    # OpenSim inverse-kinematics joint angles (deg)
    MotionCapture/LevelWalking/
      TRC/TrialXX/{Step01.trc, Step02.trc, AllSteps.c3d,
                   mosh_results/.../AllSteps_stageii.pkl}   # markers, C3D, SMPL (MoSh++) fit
      MOT/TrialXX/{Step01.mot, Step02.mot}         # ground reaction forces (2 force plates)

Coverage notes

• EMG ConvertedData.mat: all 120 subjects.
• JointAngle/LevelWalking (.mot): all 120 subjects.
• MotionCapture TRC + SMPL fit (AllSteps_stageii.pkl): all 120 subjects (5 trials each).
• Ground reaction forces (MotionCapture/.../MOT/): S011–S120 only (110 subjects). S001–S010 have no processed GRF in the source dataset.

Relationship to the original dataset

To keep the archive compact, the following were removed relative to the figshare release:

• EMG/RawData.mat and EMG/ProcessedData.mat (only ConvertedData.mat retained);
• all preview *.mp4 animations;
• all non-LevelWalking movements (StairAscent/Descent, SlopeAscent/Descent, SitToStand, StandToSit) under JointAngle/.

JointAngle/LevelWalking was (re)fetched for all 120 subjects so that branch is complete. For the full multi-activity dataset (raw EMG, stairs, slopes, sit-to-stand, etc.), use the original figshare release.
