Title : A comparative study of motor nerves conduction velocity between right handed and left handed subjects


Motor Nerve conduction study is one of the electrophysiological tests performed to evaluate electrical conduction of motor nerves. Many studies involved nerve conduction velocity of peripheral nerves, but only few addressed this issue in relation to handedness with lots of controversies in their results. This Study was conducted to compare motor nerve conduction velocity between right-handed and left-handed subjects in large sample size.

The study was carried as analytical cross-sectional study at the department of physiology, Faculty of Medicine, University of Khartoum and involved 120 healthy students from the medical campus, of whom 60 were right-handed and 60 were left-handed. Nerve conduction studies were performed using Medelec-Synergy machine. Two peripheral motor nerves of the upper limb (Median & Ulnar nerves) were investigated in each subject of the two groups bilaterally

The study revealed no significant difference in motor nerve conduction velocities of the investigated motor nerves (right-median, left-Median, right-ulnar & left-ulnar nerves) between the right-handed and the left-handed groups (P value > 0.05). Also when testing each group separately, no significant difference was found in motor nerve conduction velocities of the motor nerves (median, ulnar) between the right and left sides of the same subject, (P value >0.05).

The study concluded that there is no significant difference in nerve conduction velocity between right-handed and left-handed subjects. Same finding was found between right and left sides of the same subject, in both right-handed and left-handed groups. This proved that nerve conduction velocity has no relation with handedness.


Dr. Duaa Abdelsalam, studied Dentistry University of Khartoum, Sudan and then obtained MSc of Physiology from the same University in 2017, research experience and interest in Neurophysiology and Neuroscience. She then joined the University as a lecturer with many research relevant duties. She has participated as oral speaker in local neurology conferences and as poster presenter in different international neurology conferences.
