Abstract：There is substantial evidence to indicate that sensory-motor control of the ipsilesional upper exremity in adults after unilateral stroke is abnormal.Some of the sensory motor deficits as a function of the side of the cerbral lesion.Rapid movment of the ipsilesional UE that require precise timing and sequencing are more affected in individuals with lessions in the hemisphere.In contrast,ipsilesional movements that have cootrained spatial requirements are more affected in those with lesions in the right hemisphere.Ipsilesional UE covrdination of discrete tasks may be normal,but the coordination of continuos tasks is affected in adults with left stroke.sensation in the ipsilesional UE appears to be unaffected,or minimally affected after stroke.Strength defictits have been demonstrated in the ipsilesional UE,but premarily in those with right sided lesions.Ipsilesional performance deficits are revealed in clinical tests of function that use time to completion as the measure of success.Ipsilesional performance deficits may reflect motor control deicits that are masked on the contralatoral side by hemiplegia and hemisensory loss.Interventions that focus on specific motor control deficits,such as speed of sensory motor processing,through practice with the ipsilesional UE,may result in functional improvements in both limbs.
