EFFECT OF HAND DOMINANCE ON THE SENSORY NERVE CONDUCTION VELOCITY

ARRTHY ARRTHY

Abstract


Abstract : Nerve conduction studies are
affected by the various physiological parameters
like age, gender, height and temperature
are well known. However, research
towards the effect of limb dominance
on Sensory nerve conduction is
few. This study was planned to assess the
effect of limb dominance on sensory nerve
conduction velocities. This study comprised
of 40 young medical students of
both the genders of the age group 17-23
years, of which 30 were right handed and
10 left handed. The median nerve sensory
conduction velocity was measured and recorded
using 4 channel polygraph. The
sensory nerve conduction velocity in the
left handed subjects was found to be more
than the right handed subjects, but the difference
was statistically insignificant and
the left handed subjects had higher SNCV
in dominant hand(left) compared to dominant
hand(right) of right handed subjects
and this was also found to be statistically
insignificant. In our study the sensory conduction
velocity is higher in dominant hand
when compared to non dominant hand in
right handed subjects and the difference
was statistically significant but no
significant difference in the sensory conduction
velocity between the dominant
and non-dominant hand was found in left
handed subjects.
