Limb Dominance and Motor Conduction Velocity of Median and Ulnar Nerves

The influence of one-sided limb dominance on the muscles, bones and motor conduction velocity of median nerve has been investigated and reported. We have undertaken a more detailed study of the conduction velocity of the efferent fibres of median and ulnar nerves of both sides in 25 right-handed and an equal number of left-handed subjects of both sexes in the age group of 18-30 years. A significant correlation between "handedness" and motor nerve conduction especially in median nerve, is shown by the results in both right handers and left handers.
