Experimental-clinical psycholgical study about pain control (5) : Pain sensation and skin temperature change induced by cold pressor test

Experimentally induced pain by cold pressor test was investigated using subjective and physiological measures. Seven subjects immersed their dominant hands in cold water of 5°C, 10°C and 15°C and the skin temperatures of both hands were measured. Their pain sensation was then evaluated using 80 adjectives. Pain estimation by adjectives revealed distinctions between water temperatures including severity and mildness. Skin temperature reduced more during immersion and increased more quickly after withdrawing in colder water conditions
