The Role of Proprioception in Handedness

Despite the emphasis that has been placed on feedback utilization in the determination of handedness, most studies on motor laterality have focused on visually-guided movements. Given the number of activities that rely heavily upon previous proprioceptive experience, the extent to which limb asymmetries exist during proprioceptively-guided movements is certainly of importance. Utilizing an elbow position matching paradigm limb asymetries in the utilization of proprioceptive information are being explored under a variety of task conditions including the mode of target presentation (active vs. passive), the need for generation and/or interhemispheric transfer of target position information and the workspace within which matches are made. Thus far, a clear dominance effect has been seen during tasks that require memory-based matching of a target limb position with the contralateral arm. These results suggest that limb position feedback may be utilized differently by the dominant and non-dominant hemispheres.
