Pilot Study of Acute Stroke Using the Brainpulse™

"The BrainPulse is used on a patient's head to non-invasively detect, amplify and capture the skull motion caused by pulsatile cerebral blood flow from the cardiac cycle.~The BrainPulse consists of a reusable headset that contains the accelerometers used to measure motion caused by pulsatile cerebral blood flow. The system is powered by a rechargeable battery pack. The headset is placed on the subject's head and outputs data to a data collector that forwards the data to the computer. Each accelerometer has an attached tip that makes contact with the subject's head through hair. The headset also includes a photoplethysmograph (PPG) that simultaneously captures the subject's heart-rate information. There is no energy delivered to the brain or subject by these highly sensitive sensors."
