The present study compared two point discrimination in the dominant and non-dominant i.e. right and left sides of an individual in order to investigate the existence of any intra-individual differences in sensory perception. A total of 100 healthy adults aged between 20 & 50 years were selected and two point discrimination was assessed using baseline aesthesiometer. 8 skin areas were assessed, areas being: a) mid-lateral forearm, b) mid-medial forearm, c)palmar surface of distal phalanx of thumb, d) palmar surface of distal phalanx of long finger, e) medial leg, f) distal lateral leg, g) tip of great toe, h) over 5th metatarsal space. The results demonstrated that tactile sensibility varies in different areas of body in an individual. It was also found that two point discrimination values differ in dominant and non-dominant limbs in healthy adults. Conclusion: Intra-individual differences exist when dominance is taken as criterion.
