Shoulder abduction, front-on
Under three seconds of both arms raised out to the side, filmed front-on: the range at each shoulder, frame by frame, with the trunk checked for compensation.
- Left shoulder range, 19.8° to 162.4°
- 142.6°
- Right shoulder range, 19.2° to 173.7°
- 154.5°
- Low back range: the trunk held still
- 0.8°
- Frames, every one measured
- 80
Filmed front-on, so the report flips the right side back onto the same scale as the left; the downloads keep the engine's own clockwise angles.
