Immune Function Helped by Chiropractic - Study Says

A recent study found that a chiropractic adjustment immediately improved immune function and enables a patient to better fight infection for at least 2 hours, but potentially for much longer, by increasing certain biochemicals at the cellular level.

This study was designed to see if certain blood cells would produce more of a substance called Interleukin-2 (IL-2) after chiropractic adjustments. IL-2 is produced by blood cells and is instrumental in the body's natural response to infection. If blood cells produce IL-2, the body can fight infections more readily. IL-2 also helps the body to know the difference between a foreign threat of infection, and what is naturally inside the body.

In this study, blood samples were taken from 76 individuals. The blood samples were tested to see if they produced IL-2 when exposed to a bacteria. Then the participants were separated into 3 groups. One group was used as the control and received no adjustments. The other two groups both received adjustments, but one group received an adjustment that included joint cavitation (the familiar "popping" sound) and the other group receiving adjustments that made no sound at all.

Four blood samples were taken from the group. The first was prior to the chiropractic adjustment, the second was immediately after the adjustment, the third was taken 20 minutes after the adjustment and the final sample was taken 2 hours after the adjustment. Each sample was then tested to see how much IL-2 they produced when exposed to a bacteria.

The results documented that both groups that had some form of adjustment showed an increase of IL-2 at both the 20 minute and 2 hour times. The group that was tested at those same time intervals but had not received a chiropractic adjustment did not have a rise in IL-2 levels and therefore would not have been as receptive to fighting an infection. The researchers were therefore able to conclude that one single manipulation to the thoracic (mid-back) spine of asymptomatic subjects causes a significant enhancement in IL-2 production by blood cells when tested in a culture dish. Additionally, adjustments associated with joint cavitation demonstrated slightly better immune improvement at 2 hours than the adjustments that did not elicit a "popping" sound.

The study was published on May 28, 2008 in the scientific journal, Chiropractic & Osteopathy, by the Chiropractic & Osteopathic College of Australasia.

Dr. Richards Comments:
This study demonstrates another reason why chiropractic care is good for your overall health. Occasionally patients will cancel appointments because they "don't feel well", instead of canceling, they should keep the appointment so that their immune system can benefit.
