Interrelationship of Limb Dominance and Sensory Function Across Age

ABSTRACT

Side dominance (upper and lower extremities, visual and auditory dominance) of 3,474 subjects of different age groups (9–83 years) was assessed using a 22-item questionnaire. Data were analyzed using a trichotomous (left, mixed, and right) association analysis among indices of side dominance. The contingency coefficients showed significantly high association between hand and foot preference across age groups compared to other paired associations of side dominance. A general rightward shift was observed with increasing age in all forms of side dominance.
