Abstract

<p>We investigated the effects of sensory information from the contralateral upper limb on motor control during grasping movements of the upper limb. In the first experiment, movements of 20 healthy subjects were compared in three conditions based on the presence or absence of object grasping and vision in the contralateral upper limb. The results showed that the hand opening width was decreased in the condition of the combination of vision and contralateral upper limb grasping. In the second experiment, the movements of 20 healthy subjects were compared under the condition that the distance and size of the object were individually provided by the grasping of the contralateral upper limb. The results showed that the distance information contributed to the decrease in hand opening width, but the time required to open and close the hand tended to increase when the distance and size information were not aligned. Thus, the contribution to the control of grasping motion may depend on the spatial clarity of the integration of object vision and the somatosensory integration of the contralateral upper extremity.</p>
