ABSTRACT
Background: The osseous hand arches are key components enabling an individual for constant, consistent day to day activity performance. The variation in the arches may occur due to usage patterns of hand or it may change with respect to gender. The anatomy of hand arches, acts as the prime component by modulating the curvature of hand to increase not only the surface area for tactile stimulation but also for a better grip and grasp strength
Objectives: To provide normative data of palmar arches height in Indian population and to define the constant anatomical landmarks to measure the palmar arch height and correlate it with grasp power in healthy individuals.
Material and Methods: Hand arch morphometry was studied for 150 hands in both genders. The measurement was taken with a standardized vernier caliper for longitudinal arch height and distal transverse arch height, and their difference was analyzed for the right and left hand and for between the genders. The association of these parameters with body mass index was also assessed.
Results: The results show gender variation for grasp strength and differences in longitudinal arch height between the right and left hand. The results of the present study add to minimalistic literature regarding arch height in hand and also attempts to provide data that may be used in defining rehabilitative exercise program.
Conclusions: Differences in hand bone structure between the dominant and non-dominant hand for LAH were observed, but not for DTAH or GP. The differences between genders is observed for grasp power and LAH for left hand only. These variations could be due to usage patterns of the hand, muscle mass differences, and hormonal differences between the genders. This study has implications during the development of hand exercises program for treating neurological deficits in an individual.
