Thermogram of the soles of a person's feet suffering from rheumatoid arthritis affecting the ankle and toe joints. A thermogram is a colour- coded map of temperature distribution over the body surface. The colour coding shows variation in temperature,ranging in steps from blue-black (coolest) to white (warmest areas). Alterations in skin temperature are characteristic of certain diseases; inflammation in rheumatoid arthritis may give rise to temperature increases of up to 2 degrees C. The symmetrical areas of inflammation over both feet are characteristic of rheumatoid arthritis | |
