Muscle | Voltage electrode locations | Current electrode locations |
---|---|---|
Biceps Brachii | V1, 2.5 cm from insertion of tendon, V2, 12.5 cm proximal to V1 | Palms of hands |
Forearm Flexors | V1, 10 cm below antecubital fossa, V2 2.5 cm below antecubital fossa | Palms of hands |
Quadriceps | V1, 12.5 cm proximal to top of patella; V2, 17.5 cm proximal to V1 | Dorsum of feet |
Tibialis anterior | V1, 15 cm distal to fibular head; V2, 2.5 cm distal to fibular head | Dorsum of feet |
Medial Gastrocnemius | V1, 17.5 cm distal to midpoint of popliteal fossa; V2, 5 cm distal to same point | Dorsum of feet |
Measurements were obtained on patients lying supine, with the arms lying passively at the sides of the body and a small bolster or pillow under the knees.
