This study investigates the thermal distribution quantity in the human dorsum to assess relaxation effects. The thermal distribution in the dorsum was measured with an infrared thermal imaging camera. We developed software to transform the measured thermal images into a standard image shape. The transformed thermal images were divided into 21 regions. The average, maximum and standard deviations of temperature in each of the 21 regions were calculated statistically. We also studied changes of the thermal distribution in relation to room temperature, circadian rhythm, fat value and artifacts. For other experiments requiring measurements, the subjects removed their clothing and measurements were made at a room temperature of more than 26 ℃. The thermal distribution was stable from 2 PM to 5 PM. The average temperature in the 21 regions was also related to the fat value (r=-0.75). Changes of thermal distribution in the dorsum were measured when 7 male subjects (average age, 39.7 years) were given MPT (MOA purifying therapy). The thermal distribution was also measured when the subjects lay on a bed in a prone position (control experiment). The average temperature of the MPT experiment increased more then the control experiment. Therefore, the thermal distribution analysis of the dorsum is a useful method to assess relaxation effects.
