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. Flexor Digitorum Superficialis Flexor Digitorum Superficialis · left · Forearm Literature

Position: On the flexor side of the mid-forearm, approximately three quarters of the distance from the elbow to the wrist; flex only the fingers (not the wrist) and record where the movement is felt most clearly
Orientation: Parallel to the muscle fibres, 2 cm inter-electrode distance - quasi-specific site, crosstalk from the neighbouring finger flexors
Signal check: Flex the fingers while avoiding wrist flexion.
Crosstalk from: flexor carpi radialis — crosstalk is certain if placed too radially
MVC test: Seated or kneeling in front of a bench with the forearm resting on a stable support.
Fixation: Forearm fully supported; wrist free to work against the resistance.
Resistance: Manual resistance, a barbell or a cable/belt against the wrist or hand.
