Comparison of Somatosensory Evoked Potentials Between Genders in Healthy South Indian Population

Abstract

Evoked potential recordings (EPR) are designed to test the three most important of the five senses, touch, hearing and sight. Together, these three senses account for most of the incoming information absorbed by the brain. Evoked potentials (EPs) are important tools to study nerve impulse conduction in central nervous system. SEPs are one of the commonly used EPs which measure the transmission in somatosensory pathways. Aim of study was comparison of somatosensory evoked potentials between genders in healthy south indian population. Study was conducted in 120 healthy volunteers of both male & female in the age group of 15 to 60 years. Recording of SEPs was done in subjects. Informed written consent was obtained after explaining the procedures and answering all their queries. Normative data for Somatosensory Evoked Potential (SEP) for upper limb and lower limb in terms of both latency and amplitude were collected. statistical analysis was done using SPSS 20.0. In the present study, no significant correlation was found between gender and latencies of the waves both in upper and lower limbs. Amplitudes of the waves also could not be correlated with gender.
