Long-term recovery of muscle strength after denervation in the fibular division of the sciatic nerve.

abstract：BACKGROUND:A new technique to obtain the sensory nerve action potential (SNAP) of the medial femoral cutaneous nerve is described. METHODS:SNAPs were recorded from 104 subjects with a bar recording electrode 10 cm proximal to the patella along an imaginary line drawn between the medial edge of the patella and the femo...
