Abstract

Nerve conduction velocity which asseses peripheral nerve function for diagnosis of neuropathies,
is known to vary with age, height, body weight and body mass index (BMI). This experimental
study investigated the relationship between these factors on nerve conduction velocity in median
and ulnar nerve among 64 normal subjects by using the Pearson’s correlation. It was found that
nerve conduction velocity in median (p < 0.01) and ulnar nerve (p < 0.01) was negatively correlated
with BMI. An age was negatively correlated with nerve conduction velocity of only ulnar nerve, but
conduction velocity in both nerves did not show correlation with body weight (p 0.0959, 0.2073)
and height (p 0.2376, 0.0646).
Key words: nerve conduction velocity, median nerve, ulnar nerve, normal subject
