Abstract Background and Objectives Handedness is an attribute of human beings defined by their unequal distribution of fine motor skill between the left and right hands. The preference for the right or left hand has been correlated with the laterality, cerebral dominance and asymmetries in the brain. Various studies have investigated the relationship between hand preference for different activities, and varied results have been obtained. The results also varied with the different cultural backgrounds, establishing a need to investigate it further. Method and Materials A total of 150 participants of age group 4 to 30 years took part in the study. The handedness was evaluated by Edinburgh Handedness Inventory, hand digit mapping was assessed by asking the subjects to count and performance was measured by pegboard task. The data was correlated with handedness. Results The Pearson correlation coefficient for handedness and difference in performance score of right handed and left handed for all 150 subjects was significant with P= 0.05. The Pearson correlation coefficient for handedness, month counting and number counting was not significant for all 150 subjects. Conclusion A significant correlation was found between the right hand performance and handedness in Indian population whereas no correlation was found between handedness and hand digit mapping in Indian population.
