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. Deltoideus Pars Spinalis Posterior Deltoid · right · Shoulder SENIAM

Position: 2 finger widths behind the acromial angle
Orientation: Toward acromion–little finger
Signal check: Extend, abduct or laterally rotate the arm.
Crosstalk from: middle deltoid · infraspinatus · teres major · triceps brachii
MVC test: Seated with the trunk supported, arm at about 90° flexion or prone on a bench with the arm hanging.
Fixation: Trunk fixed; upper arm fixed near the test position.
Resistance: Manual resistance or strap against the back of the upper arm, extension / horizontal abduction against it.
