Abstract

BACKGROUND: Cerebral autoregulation can be impaired after ischemic stroke, with potential adverse effects on cerebral blood flow during early rehabilitation. OBJECTIVE: The objective of this study was to assess changes in cerebral blood flow velocity with orthostatic variation at 24 hours after stroke. DESIGN: This investigation was an observational study comparing mean flow velocities (MFVs) at 30, 15, and 0 degrees of elevation of the head of the bed (HOB). METHODS: Eight participants underwent bilateral middle cerebral artery (MCA) transcranial Doppler monitoring during orthostatic variation at 24 hours after ischemic stroke. Computed tomography angiography separated participants into rec..
