Brief Summary:
A double-blind crossover randomized controlled trial to investigate the effects of the AVACEN device on fasting 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 was tested while using each of these three devices 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 30 minutes that the device was used.
