SPARK Study - Sympathetic Periarterial Radial Block in Healthy Volunteers
RandomizedParallel-groupSingle-blindBasic science
Summary
The SPARK Study evaluates changes in peripheral sympathetic vasomotor activity following a targeted, ultrasound-guided periarterial sympathetic block of the distal radial artery in healthy volunteers. Autonomic reactivity will be assessed before and after the block using digit-specific pulse-amplitude index and infrared thermography during standardized cold pressor testing.
