How It All Began
Evolution and Limitations of Thermal Imaging in Chiropractic
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 the use of two bilateral points. The body is not precisely symmetrical. There are scars, skin folds, pimples, hairlines, and postural differences that make it impossible for symmetrical analysis. As the thermal device is scanned over an area it picks up a single point temperature measurement. This reading is very accurate with infrared, but it is limited in value.
Tech Spotlight: A Clearer, Smarter View
Digital thermal imaging changes the game. A modern 640×480 thermal camera captures up to 307,000 individual temperature points — providing a much more complete and precise image of the body’s thermal profile. Even better, prices for these advanced cameras have dropped significantly in recent years — now often costing less than traditional dual point equipment.
Philosophy vs. Physiology
Rethinking Pattern Analysis and Chiropractic Theories
Pattern Analysis: There is contradictory evidence on the original theory by BJ Palmer that a thermal pattern “in pattern” is a sign of subluxation. Patterns have actually been found to be the “norm”. The body has a thermographic “fingerprint” that only changes when something changes it physiologically. The previous thought was that the adjustment “breaks” the pattern and restores the dynamic life force to the body. The change on the pre and post test is present because the pressure from the device on the skin in addition to the adjustment changes the skin surface temperature, and a subsequent change in temperature is measured.
Case Observation: The Bald Man Temperature Test
With upper cervical dual point analysis, we often find a temperature difference at the atlas of one degree or more. This discrepancy is usually due to the hairline—hair is colder than skin and registers as a colder point on thermal scans.
To test this, perform a dual point scan on a person, shave their head, and re-measure the next day. Results often show no temperature difference post-shaving. Interestingly, bald individuals rarely show that one-degree temperature break at the atlas. Could this mean bald men subluxate less? Food for thought.
Data-Driven Care
Monitoring Progress with Objective Thermal Imaging
True objective measurements can be compared along a course of treatment. The patient can actually validate their problems on the screen. They can then see their condition improve over time.
We urge chiropractors to take advantage of this amazing technology and bring chiropractic science to modern times. A thermal camera is an extremely useful tool for the chiropractor. Nerve compressions will frequently show up as hypothermic areas, while inflammation shows up hot, or red.
