Recording set-up per Konrad 2005: Inter-electrode distance 2 cm (centre to centre) · Skin impedance: aim < 10 kΩ, up to 30 kΩ acceptable, above 50 kΩ prepare again · Band-pass 10–500 Hz · Sampling ≥ 1000 Hz · no notch filter

S1 M. Rectus Abdominis Rectus Abdominis · right · Trunk Anterior Literature

Position: 4cm lateral to the midline, at the level of the navel
Orientation: Parallel to the muscle (vertical)
MVC test: Supine, knees bent, sit-up style: flex the spine by about 30° and hold that position.
Fixation: Very good leg fixation is essential; hold the 30° position with a belt or manually.
Resistance: Belt or manual resistance against the chest, trunk flexion against it.
