Could a wrist band replace the bulky blood pressure cuff?
NCT ID NCT07099716
First seen Jun 26, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study will test a new wrist-worn device called the Hilo band that measures blood pressure continuously over 24 hours. About 330 adults with high blood pressure will wear the Hilo band along with a standard arm cuff monitor and a chest sensor. The goal is to see how well the Hilo band works compared to current methods and whether people find it comfortable and easy to use.
