Abstract
Careful nerve conduction studies in
patients with polyneuropathy can provide
useful information for differential diagnosis
of the pathophysiological processes and in
search of their underlying etiological factors.
We systematically studied nerve conduction
velocities of the right median nerve with
different techniques in 128 normal controls,
19 patients with acute demyelinating
polyneuropathy, 36 patients with chronic
demyelinating polyneuropathy, and 16
patients with diabetic polyneuropathy.
Techniques to study the nerve conduction of
the median nerve included motor nerve
conduction with measuring the latency of
evoked compound muscle action potentials;.
sensory nerve conduction with measuring
the latency of evoked sensory action
potentials; centripetal nerve conduction with
measuring the latency of the centripetally
recorded nerve action potential; centrifugal
nerve conduction with measuring the latency
of the centrifugally recorded nerve action
potentials; nerve conduction by measuring
the latencies of scalp somatosensory evoked
potentials to stimulation of the median nerve
distally and proximally. We found that nerve
conduction velocity (NCV) through motor
fiber stimulation was slower than that
through any other techniques. In the patients
with acute demyelinating polyneuropathy,
NCV through centrifugally recorded
technique did not slow significantly as
compared with that in the normal controls.
NCVs from other diagnostic techniques
were lower than those in the normal controls.
In chronic demyelinating polyneuropathy,
NCV obtained from any electrodiagnostic
technique was slower than the NCV with
comparable technique in the normal controls.
The normal controls and the patients with
chronic demyelinating polyneuropathy had a
same pattern of NCV difference among
various electrodiagnostic techniques.
