Within this book the reader will find the effect of limb dominance on motor nerve conduction velocity of median and ulnar nerves in forearm segment and will be able to analyze whether some significant relationship exists between motor nerve conduction values in right handers and left handers. For this 30 healthy volunteers (20 Female, 10 Male) with the mean age of 23 yrs (20-26yrs) participated in the study. Edinburgh handedness inventory was used to asses the laterality of subjects. Median NCV for the forearm segment was calculated for each upper limb of 30 subjects. This book may be of help to physiotherapist, clinician, neurophysiologist or a learner who face the same research problem and may become comprehensive guide to them.
