In order to identify limb difference in reaching movements, the present study investigated interlimb kinematic differences at nine positions in left- and right-hemispace among 16 strongly lateralized right-handers. Angular deviations at the time of peak acceleration (PAD), peak velocity (PVD), and peak deceleration (PDD) during reaching actions were employed to examine kinematic differences between limbs in terms of planning and feedback processes. PADs and PVDs were found significantly smaller with the right-arm for more lateral object positions in right hemispace such as 40° and 30°. However, interestingly, for bilaterally symmetric positions in left hemispace such as -40° and -30° the left-arm showed smaller angular deviations than the right-arm. These results are in contradiction to both traditional and contemporary views in terms of the dominant right-arm’s superiority of execution and specialization for planning. With regard to the PDD data, the dominant right-arm showed smaller PDDs than the non-dominant left-arm across object positions, reflecting more accurate final positioning with the right-arm. The current results seem to point to inconsistencies with advantages of the non-dominant hemisphere limb system in the contemporary view, indicating more accurate final positioning with the left-arm as a result of advantages of sensory feedback processing. Rather, these results support the traditional view, indicating the superiority of the dominant right-arm and the inferiority of the non-dominant left-arm in all aspects of limb execution. Considered together, the findings from the present study are hardly enough to explain the distinct functional specialization of each hemisphere limb system. Thus, the present data suggests that the limb difference in kinematics of reaching movements is driven by movement efficiency, not just by hemispheric difference of the brain.
