Assessing Impacts of Static Magnetic Fields on Peripheral Pulses and Skin Blood Flow

Not Applicable

Completed

• Conditions: Magnetic Field Exposure; Arterial Stiffness; Peripheral Arterial Disease

• Registration Number: NCT04539704
• Lead Sponsor: Nova Southeastern University

Brief Summary

The purpose of this research study is to investigate and determine the effects of static magnetic fields produced by a small magnet on peripheral pulses and skin blood flow.

Detailed Description

A specific neodymium magnet and sham device will be placed on certain sites near the ulnar and medial arteries and the effect of such placement on peripheral pulses assessed via PPG on fingers and on skin blood flow via laser Doppler perfusion determined. These assessments will be made while healthy subjects are lying supine on a padded examination table over a time interval of about 45-60 minutes. In addition to the impact that either the magnet or the sham devices have, the pulse and skin blood flow patterns and features will be analyzed from the point of view of sequential variability with and eye toward developing related parameters to potentially improve such variability.
