Pilot Study of Acute Stroke Using the Brainpulse™
Non-Blinded Data Collection Pilot Study of Acute Stroke Using the Brainpulse™
Study Overview
Detailed Description
The study is a prospective, non-randomized, non-blinded, hospital-based study of patients presenting with acute stroke symptoms within 24 hours of symptom onset (last known normal or actual time) as evidenced by radiological imaging. The study will be executed in two parts: Study Part I and Study Part II. Each study part will consist of the same sequence of events and study procedures. The first part of the study is designed to enroll a smaller sample size to evaluate the feasibility of incorporating the BrainPulse device in the Stroke patient care workflow.
Patients will be consecutively recruited and once patients have consented and met eligibility, they will be assigned to one of the four study Groups based on their confirmed clinical diagnosis. Each subject will complete one BrainPulse recording before neuro-intervention and within one hour of IV pharmacologic intervention. All subjects will also complete comprehensive neurological, cognitive and NIH Stroke Scale (NIHSS) assessments. Additionally, Ischemic Stroke subjects (Group A) that receive neuro-intervention will complete one BrainPulse recording within four hours after intervention along with a neurological exam. If these procedures have been completed as part of standard of care, the data can be captured directly from the medical records. If such procedures were not conducted as part of hospital's standard of care, they will need to be completed for the purpose of the study.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Group A: Large-Vessel Ischemic Stroked
Group A will include subjects that present with focal neurological deficits and clinical features consistent with ischemic stroke with a large vessel occlusion (see Key Terms for definition).
Subjects in this group will have a clinical presentation consistent with ischemic stroke and a large vessel occlusion confirmed through angiography.
It is common practice to have the CTA completed immediately after CT imaging.
Clinical presentation will include classic features of stroke syndromes that occur based on the localization of the infarct, which includes cortical symptoms that can be lateralized to the left side or right side of the brain.

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. |
Group B: Hemorrhagic Stroke
Subjects in this group will present with symptoms similar to Group A. In addition, they will present with clinical symptoms consistent of increased intracranial pressure such as nausea, vomiting, loss of consciousness and severe headache.
In order for a subject to be eligible, the hemorrhage will be limited to primarily intracerebral hemorrhage with a minimum volume of 10mL.
Subarachnoid hemorrhage and intraventricular hemorrhage may also be present as incidental findings.
Since it is unlikely that these subjects proceed for neuro-intervention, they will not have a follow-up BrainPulse recording and they will be exited after completing study procedures.

Group C: Transient Ischemic Attack
Subjects in this group will present with focal neurological symptoms consistent with stroke.
In order for subjects to be eligible for this group, enrollment will need to be within 6 hours of resolution of symptoms along with a confirmation of TIA by treating team.
In addition, initial and follow-up radiological imaging needs to show that there are no signs of ischemic stroke or hemorrhage.

Group D: Non-Stroke Subjects
Subjects in this group will present with stroke-like symptoms but do not have a diagnosis of stroke nor TIA.
In order to qualify for this group, subjects will also need to show evidence of no stroke on radiological imaging (CT and/or MRI).
Diagnoses in this group may include seizure, systemic infection, brain tumor, metabolic disorder, positional vertigo, hemiplegic migraine, encephalopathy, cranial nerve injury, spinal cord injury, brachial/sacral plexus injury, peripheral nerve injury, etc.
