✦ Synopsis
Lumbosacral roots could be tested either by means of magnetic coil stimulation* or electrically using needle electrode inserted to the laminar level.' We studied 15 normal subjects and 20 patients with lumbosacral root disorders to compare these stimulation techniques.
The magnetic stimulator with a 9-cm diameter coil (Magstim-200) was placed over the L3-4 or

We compared the frequencies and types of motor conduction abnormalities found in peroneal and tibial nerves of patients with either L5/S1 radiculopathies (n = 47) or axonal polyneuropathies (n = 49). In axonal neuropathies, compound muscle action potentials (CMAPs) were more likely to be either unob
## Abstract To identify the segmental innervation of L‐2–S‐1 muscles, we compared the preoperative electrodiagnostic examinations of 45 patients with single‐level lumbosacral radiculopathies confirmed radiologically and surgically. The electrodiagnostic findings were classified as abnormal only by
