Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This is a single institution, single-blinded, long-term exploratory study using participant as his/her own control to evaluate and compare the potential analgesic effect on experimental heat pain of Transcutaneous Magnetic Stimulation (TMS). TMS will be delivered by a commercially available device (Rapid2, Magstim Corp) at three different cortical target sites and one sham target site in healthy participants 18-88 years of age. The quantitative evaluation measure is the change in the painful heat threshold Quantitative Sensory Testing (QST) of thresholds for cutaneous heat stimuli before and after TMS.
