Recording set-up per Konrad 2005: Inter-electrode distance 2 cm (centre to centre) · Skin impedance 5–50 kΩ, aim low · Band-pass 10–500 Hz · Sampling ≥ 1000 Hz · no notch filter

S1 M. Biceps Brachii Biceps Brachii · left · Upper Arm SENIAM

Position: 1/3 on line between cubital fossa and medial acromion (measured from the cubital fossa)
Orientation: Parallel to line cubital fossa–acromion
Signal check: Flex the forearm; resistance augments the signal.
Crosstalk from: brachialis · deltoids · triceps brachii · forearm extensors
MVC test: Seated or kneeling in front of a bench, elbow at about 90°, forearm supinated.
Fixation: Very stable fixation of elbow and trunk; the upper arm stays vertical at the side.
Resistance: Rigid resistance under the wrist (strap to the floor, bar or manual), elbow flexion against it.
