Abstract
Cerebral autoregulation (CA) as a mechanism to protect the brain from ischemia or hypoperfusion may play an important role related to post-stroke interventions such as the physiotherapy and the outcome. Here, we present a non-invasive assessment of the CA status by diffuse correlation spectroscopy (DCS) measures calculating the DCS moving correlation coeffcient CBFx with arterial blood pressure (ABP). The measurements are performed during the first mobilization after the onset of the symptoms. The CBFx is compared to values obtained in a healthy population showing signicantly higher values in the stroke population. This may pave the way for personalized treatment.
