Handedness; Sensory Nerve Conduction Study; Median Nerve; Ulnar Nerve INTRODUCTION Sensory nerve conduction studies (SNCSs) are specific measurement for functional integrity of peripheral sensory nervous system as well as invaluable testing in clinical electrophysiology testing and these studies confirm for underlying abnormality to differentiate at pre-ganglionic level or post-ganglionic level in large myelinated axons. MATERIALS AND METHODS This present study was conducted on 91 healthy subjects by the use of instrument RMS Aleron EMG/NCV EPII Mark-401 instrument 4 channels with written consent after obtaining permission from Human Ethics Committee, Government Medical College, Bhavnagar, Inclusion Criteria Normal healthy subjects, age between 15 and 65 years, were included in the study. Instrument Settings Low-frequency filter: 20 Hz, high-frequency filter: 3 KHz, Sweep speed: 2 ms/division, sweep gain: 3 pV/division, Stimulus: Duration: (100 ps) 50-1000 ps, intensity current: 0-50 ma, rate of stimulation: 1 H. Participants were kept in supine position; skin surface was cleaned with spirit swab and allowed dry before placing electrodes on upper limbs to avoid any error.
