... consisted of anterior circulation cortical (n = 11) and subcortical (n = 11) strokes within 48 h of symptom onset. Cerebral blood flow velocity was measured using transcranial Doppler ultrasound, and BP measurements were recorded before, during and after the release of bilateral thigh cuffs in 10 controls...
