Abstract

[Purpose] Previous studies have reported on motor deficits in the ipsilateral upper limbs (UL) of a damaged brain hemisphere in motor tasks. However, little is known about sensory deficits on the ipsilateral side. Therefore, we investigated whether both motor and sensory function of the ipsilateral UL are affected in patients with stroke. [Subjects and Methods] Fifty patients with unilateral stroke and 40 age- and sex- matched normal subjects participated in this study. Subjects were evaluated on performance of a tracking task for motor function, and by the joint reposition test for integrity of proprioceptive sense in the ipsilateral UL. [Result] The comparison of the stroke group and the control group showed significant differences in performance of the tracking task and the joint reposition test. The accuracy index for the tracking task showed significant correlation with the error score for the joint reposition test in the stroke group. [Conclusion] These results suggest that the ipsilateral UL of stroke patients has impairment in sensory function which is related to proprioceptive sense, along with motor deficits. Therefore, we think that the difficulty stroke patients experience with motor tasks for the ipsilateral UL is induced by diminished integrity of sensorimotor function due to both sensory and motor deficits.
