Question 13

Sural sensory nerve

Answer 13

S1 nerve root
Common fibular and tibial nerves combine laterally and distally to make the Sural
Bar below and distal to lateral malleolus
Stimulate 14 cm proximally just lateral to midline of gastroc

Question 14

Saphenous nerve

Answer 14

L3 - L4 nerve roots
Continuation of the femoral nerve
Place reference bar between the medial malleolus and Tibialis Anterior tendon
Stimulate 14 cm proximally on the medial border if the tibia

Question 15

Tibial motor nerve to the Abductor Hallucis

Answer 15

S1 - S2 roots
Sciatic nerve -> Tibial nerve -> Medial plantar branch
G1 is placed anterior and inferior to the navicular
Reference on first MP joint
Stimulate 8 cm proximally and then again at popliteal fossa

Question 16

H reflex equation

Answer 16

( a x 0.46) + 9.1 + b +/- 5.5 = range that the H reflex should lie within

a = distance in cm between the popliteal fossa and superior medial malleolus
