Galvanic skin response during pain pressure threshold tests

This study aims to see the correlation between skin resistance and pain during pain pressure threshold tests. A Galvanic Skin Resistance sensor is used to measure the patient’s skin resistance. Two electrodes are placed on two adjacent fingers. A blunt tipped tool is pressed into the patients median nerve, located between the index finger and thumb. This area is known to usually be tender and with little force can inflict noticeable pain. This ensures no long term physical damage to the patients tissue. Sixty tests were made in total on the test subject, the author. On each test there are two noticeable dips in skin resistance. One, when the tool first contacts the patients skin, and another when pain is actually felt. Graphs depicting the direct correlation between force and skin resistance are made to visualize at what force the patient had the lowest skin resistance.
