Official title

Non-Blinded Control Study of Healthy Adults to Investigate the Morphology of the Headpulse Waveform Under Normal Conditions

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The REFRESH study is designed to collect data related to a signal in the brain that MindRhythm has named the Headpulse. The Headpulse occurs as a natural movement of the brain in conjunction with the beating of the heart. 500 "normal" subjects who are considered healthy as they do not have any current known neurological injury will collect the brain signal data from the non-invasive headband style headset for a duration of 3 minutes either once or multiple times. Upon consenting to participate to the study by way of the accompanying MindRhythm app, participants will be sent a Harmony headset kit which will include ECG leads to collect cardiac data in conjunction with the brain signal. The participant will receive training materials and instructions on how to collect and transmit data to investigators by way of the MindRhythm app. The data collected by these "normal" patients will be used as a comparator to individuals who are suspected of neurological injury. This data will assist in training the data analysis algorithm to optimize its diagnostic abilities in detecting neurological injury or abnormalities including but not limited to stroke, stroke type, and concussion. The data set will also be analyzed to determine how the signal varies within an individual and amongst other "normals." An additional benefit of collecting this data will be to gain knowledge related to the ergonomic factors of the app and the headset and its "user friendliness."
