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. Gluteus Maximus Gluteus Maximus · right · Hip SENIAM

Position: 50% on line between sacrum and greater trochanter
Orientation: Along the line posterior superior iliac spine–middle of the posterior thigh
Signal check: Prone or standing (hands on the wall), extend the leg backwards; alternatively stair stepping, sit-to-stand, external rotation of the thigh.
Crosstalk from: usually not a problem per Criswell
MVC test: Prone, hip hyperextension of about 20° with slightly outward-rotated leg; test with extended and with flexed knee.
Fixation: Pelvis fixed on the bench.
Resistance: Manual resistance or belt against the back of the thigh, hip extension against it.
