The Effect of Topical Local Anesthetics on Thermal Pain Sensitivity in Patients with Irritable Bowel Syndrome

<table>Continuous thermal stimulus applied to thenar eminence of right hand of IBS (open bars) and control (gray bars) participants during baseline sessions. Thermode temperatures during induction phase at the time when pain intensity first reached 10% and 25% were lower for the IBS group compared to controls. The average temperature needed to maintain pain intensity at 25% was also lower for the IBS group.</table>
