NCT04018976

Brief Summary

A double-blind crossover randomized controlled trial to investigate the effects of the AVACEN device on postprandial blood glucose. The AVACEN device creates negative pressure around the hand while heating the palm. Two sham devices, one providing heat but no vacuum and one providing neither heat nor vacuum were also used. Each subject will use each of these three devices during the first hour of a 2-hour oral glucose tolerance test on separate visits. Subjects arrived in the morning following an overnight fast. Fasting blood glucose, blood pressure, tympanic temperature, and subjective thermal ratings were measured before and throughout the 2-hour oral glucose tolerance test.
