NCT ID NCT05554315
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a new technique called speckle plethysmography to measure blood pressure continuously using light sensors on the fingers and toe. Forty healthy adults wore the sensors while doing tasks like slow breathing, math problems, and putting a hand in ice water. The goal was to see if this method could track blood pressure changes without a traditional cuff.
