Medial and Lateral Plantar Mixed Nerves (orthodromic)

Origin:  S1 root, sacral plexus, sciatic nerve, tibial nerve

Recording Site:  Ankle (bar electrode)

Reference Site:  Ankle (bar electrode)

Ground:  Top of foot

Stimulation Site:    

            Medial foot (medial plantar)
            Lateral foot (lateral plantar)
 
Procedure:  The recording/reference bar electrode is placed with G1 distal in the hollow of the flexor retinaculum on the medial side of the ankle by the medial malleolus  The stimulation site for the medial plantar nerve is 14 cm from G1 in a straight line between the big and second toes.  The stimulation site for the lateral plantar nerve is 14 cm from G1 in a straight line between the fourth and fifth toes.
