Although neuropathies of the infrapatellar nerve (infrapatellar branch of the saphenous nerve, IPBSN) have been reported clinically, no electrophysiological method has been defined to evaluate IPBSN conduction. We therefore studied a total of 60 saphenous nerves and 60 IPBSNs from 36 volunteers. The IPBSN was stimulated medially with a surface electrode 2 cm below the patella. The response was recorded with a needle electrode located close to the nerve 1 cm lateral to the femoral artery in the inguinal region. Sensory nerve action potentials were obtained from each subject; mean latency of the first positive peak was 8.1 ± 0.9 ms, conduction velocity was 54 ± 4.4 m/s, and response amplitude was 1.3 ± 1.1 μV. The method that we describe may be an easy and useful electrophysiological test for neuropathies of the IPBSN. Muscle Nerve, 2006
