Thermal imaging of the body is a non-invasive imaging technique, using a special infrared-sensitive camera for recording digital images and changes in the surface temperature of the human body. It is a specialized camera used to capture images of thermal skin motifs. The recorded images are called thermograms.
The camera detects heat or infrared radiation spontaneously emitted by the microcirculation of the skin. These measurements are transformed into live images, which, in essence, are a reflection of the autonomic nervous system. Changes in neurological and musculoskeletal systems, caused by dysfunction or trauma, can be easily monitored.
In the diagnosis of pain syndromes, infrared imaging has the unique ability to reflect physiology. The chiropractor can “see” the physiology of the body and evaluate the integrity of the peripheral autonomic nervous system. Infrared imaging is the only technique that allows a chiropractor to visualize, with live images, physiology. The method is used to locate sub-or hyperthermal regions.
The camera provides the physiological image of the patient’s symptoms and also allows treatment to be targeted for the actual source of the problem rather than the area where the patient feels pain. The infrared camera helps estimate the effectiveness of a given treatment protocol by comparing thermal images before and after a treatment. These objective temperature finds are recorded, allowing the patient to be monitored and progressed throughout the treatment.
The body acts as thermal reference due to the thermal symmetry of the opposite sides. When compared to each other, the sides should be a mirror image within 1 ° C. This thermoregulatory cutaneous mechanism is controlled by the sympathetic nervous system.
Emotions may have a thermal signature or may be characterized from the activity of the autonomic nervous system, which in turn provides a thermal footprint through which it can be detected. In fact, thermal imaging has been suggested as a possible tool for creating an atlas of the thermal expression of emotional states. Redness, anxiety, fear, excitement and even cheating all have thermal signatures that can be detected with thermal imaging cameras. A study, for example, suggested that the temperature and monitoring of blood flow from the skin during an interrogation provides 87.2% accuracy in the detection of misleading people.
