Study Summary

Background: Much is known about how people perceive light touch, temperature, and pain. But less is known about how deep pressure is perceived. Deep pressure is an important part of many touch therapies, like massage therapy. Researchers want to learn more to help people with chronic pain and other disorders. Objective: To find out which sensory nerve fibers are involved in feeling the sensation of deep pressure. Eligibility: Healthy people ages 18 50 enrolled in study number 16-AT-0077 Design: Participants will be screened under study number 16-AT-0077 Participants will have 1 visit that lasts about 2 hours. Participants will have a brief medical interview. They will have a urine test. Participants will have ischemic nerve block on 1 arm. A blood pressure cuff will be inflated until the arm is numb for up to an hour. Participants will have tests to see how they perceive different sensations. They will rate gentle brushing on the hands and forearms. They will rate gentle pressure squeezing from a hand massager on the hands and forearms. Participants will receive other sensations such as vibration, cool, warm, pinprick without piercing the skin, finger movement, and pressure. They will be asked to rate or respond to the sensations. They will be asked to rate any pain or discomfort from the nerve block on an ongoing basis.

Primary Outcome

Difference between left (blocked) and right (control) arms in the change from baseline to after loss of A-beta sensation from nerve block. Measurement of perceived pressure intensity was assessed using a visual analog scale ranging from "no sensation" (0) to "highest possible intensity" (100).
