Table 1 Electrode placement
Muscles | Electrode placement (location and orientation) |
|---|---|
upper trapezius | 50% on the line from the acromion to the spine on vertebra C7, in the direction of the line from the acromion to the spine on vertebra C7 |
anterior part of deltoid | at one finger width distal and anterior to the acromion, in the direction of the line between the acromion and the thumb |
middle part of deltoid | line from the acromion to the lateral epicondyle of the elbow, at the greatest bulge of the muscle, in the direction of the line between the acromion and the hand |
posterior part of deltoid | two fingerbreadths behind the angle of the acromion, in the direction of the line between the acromion and the little finger |
infraspinatus | approximatively 4 cm below the spine of the scapula, over the infraspinatus fossa on the lateral aspect of the muscle, parallel to the spine of the scapula |
