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. Semitendinosus Semitendinosus · right · Thigh Posterior SENIAM

Position: 50% on line between ischial tuberosity and medial epicondyle of the tibia
Orientation: Parallel to line ischial tuberosity-medial epicondyle
Signal check: Prone: flex the knee against resistance; standing: flex the knee.
Crosstalk from: lateral hamstrings (biceps femoris) · semimembranosus · quadriceps
MVC test: Prone, unilateral knee flexion held at about 20–30° knee flexion.
Fixation: Very good hip fixation (belt or a heavy person holding the pelvis).
Resistance: Manual resistance or strap at the heel, knee flexion against it.
