Abstract

The present study was carried out in a group of 300 adults to study the correlations between functional lateral preferences-handedness, footedness, eyedness, earedness & preferred chewing side & postural lateral preferences – arm folding, hand clasping, leg crossing & side preference while lying. 90% were right handed & 10% were left handed. Significant association was present between functional lateral preference for right handedness with footedness, eyedness, earedness , preferred chewing side & postural lateral preference- arm folding & hand clasping; for left handedness with footedness, eyedness, hand clasping, leg crossing & side preference while lying. Significant correlation was found between right leg crossing & footedness, eyedness, earedness, hand clasping, arm folding & between left leg crossing with earedness & hand clasping. Right side preference while lying was positively associated with hand clasping & leg crossing.

Significant cross laterality was observed between left handedness earedness, preferred chewing side & arm folding; left arm folding & hand clasping ; left leg crossing & footedness, eyedness & arm folding ; left side preference while lying & arm folding, hand clasping & leg crossing ; right side preference while lying & arm folding.
