Thermography in Chiropractic History

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.

Limitations of Bilateral Point Measurements

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.

The Advantages of Digital Thermal Imaging

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.

Modernizing Chiropractic with Thermography

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.

Pattern Analysis in Thermography

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.

The Impact of Hairlines on Temperature Readings

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.

Objective Monitoring of Patient Progress

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.
