Thermography has been a traditional part of chiropractic analysis since BJ Palmer and the early days of chiropractic history. The dual-point approach has deep roots in the profession.
There are many problems with using two bilateral points. The body is not precisely symmetrical, and factors such as scars, skin folds, pimples, hairlines, and postural differences make symmetrical analysis impossible. As the thermal device is scanned over an area, it picks up a single-point temperature measurement. While infrared readings are highly accurate, their value is limited.
A bigger picture is seen with digital thermal imaging. Point measurements can be taken from this technology as well as 307,000 other points with a 640×480 camera. The prices of these cameras have fallen drastically in recent years, making them more affordable than most dual-point equipment.
Chiropractors are encouraged to take advantage of this technology to bring chiropractic science into modern times. A thermal camera is an extremely useful tool for chiropractors. Nerve compression frequently appears as a hypothermic area, while inflammation shows up as a hot or red region.
There is contradictory evidence regarding BJ Palmer’s original theory that a thermal pattern “in pattern” is a sign of subluxation. Research has found that thermal patterns are actually the norm. The body has a thermographic “fingerprint” that only changes when a physiological change occurs. The previous thought was that the adjustment “breaks” the pattern and restores the dynamic life force to the body. However, changes in pre- and post-testing can be attributed to the pressure of the device on the skin and the adjustment itself, which alters the surface temperature.
With the upper cervical dual-point analysis, a temperature difference of one degree or more at the atlas is commonly observed. This difference is often due to the hairline in the region, as hair is colder than skin and can create a false reading. A simple experiment can demonstrate this effect—taking a dual-point reading before and after shaving the head. Results consistently show that bald men do not exhibit the same one-degree temperature difference at the atlas, challenging the idea that this measurement is always indicative of subluxation.
True objective measurements allow for comparisons over the course of treatment. Patients can visually validate their condition on the screen and track improvements over time.
