A cross-sectional study to evaluate hand preferences from performance measures namely work done, nerve conduction velocity, and bimanual coordination among phase I medical students

Background and Objective of the Study: Most of the individuals classify themselves as right or left handed but it is not entirely clear whether handedness should be determined based on preference inventories, hand performance tasks, or a combination of both. The strength and significance of the relationship between hand preference and performance asymmetries have always been contested. Materials and Methods: This cross-sectional study has evaluated different performance measures to predict hand preference among a total of 150 1st year medical students. The performance measures included work done by ergography, nerve conduction velocity test, and bimanual coordination test. Results: A statistically significant correlation was found between hand performance and preference measures (P < 0.05 was considered as significant). Conclusion: This study helps to understand the degree of hand dominance on various performance tasks. In particular to medical profession, this study may help in the modifications of the instruments and training given to medical students in improving their bimanual dexterity.
