# Gait120 — Human Locomotion & EMG (cleaned subset)
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
**Added** files:
- For each subject and trial, MotionCapture/LevelWalking/TRC contain **mosh_results** (SMPL-retargeted motions) in AllSteps_stageii.pkl;
- For each subject, original .mat files contained opaque objects so they were converted (**ConvertedData.mat**).
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 non-`LevelWalking` movements (StairAscent/Descent, SlopeAscent/Descent, SitToStand,
StandToSit) under `JointAngle/`.
