Objective: We assessed the motor stimulus to blood flow velocity (BFV) changes of bilateral middle cerebral arteries (MCAs) by transcranial Doppler (TCD) sonography in patients with acute ischemic cerebrovascular events and normal subjects.

Material and Methods: Fourty-three patients (20 female, 23 male; aged 55.6 years) with acute territorial stroke in the MCA territory, 38 patients (11 female, 27 male; aged 57.6 years) with acute lacunar stroke in the MCA territory, and 19 control subjects (9 female, 10 male; aged 53.5 years) were investigated. Bilateral TCD sonography from both MCAs were monitored during 10 cycles of 20 seconds when subjects are performing hand gripping with a frequency of one per second, and subsequently 20 seconds when they are rest to assess BFV changes on activated cortical motor areas. BFV increase was calculated off-line for each subjects.
