Laterality is the tendency of the cerebral hemisphere to specialize in function.

To confirm the prediction of lateralized motor ability we tested grip strength and finger tapping rate in 21 right-handed hemiparetic patients due to cerebro-vascular disease and 21 right-handed age and gender matched controls. GRIP and TAP tests are common measures of motor function selected to distinguish rapid repetitive vs sustained performance.

Right hemispheric cerebrovascular accident(R-CVA) patients exhibited lower grip power than controls in right hand and left hemispheric cerebrovascular accident(L-CVA) patients exhibited lower finger tapping rate than controls in left hand.

In addition, L-CVA male patients had the enhanced abilities in left hand grip power compared to contols.

It was concluded that individuals behave differently depending on hemisphere of stroke, and some implications for the poststroke motor rehabilitation program were discussed.
