Abstract

Conduction velocity of the saphenous nerve was studied antidromically. The value in 20 control subjects was 42.22 ± 4.83 (SD) m/sec.
In 7 patients with femoral neuropathy, the sensory nerve conduction in the symptomatic nerves was definitely abnormal : nerve potential was absent in 4 and conduction velocity was slow in 2. In 1 patient, a possible asymptomatic femoral neuropathy was suggested by this test.
Conduction velocity of the saphenous nerve can be used as an objective diagnostic aid in femoral neuropathy, saphenous neuropathy and polyneuropathy.

Keywords: femoral neuropathy, saphenous neuropathy, antidromically
