Chiropractic and Immunity
In this study, seventy-six asymptomatic subjects were randomized to receive an upper thoracic (upper mid-back) spinal manipulation (chiropractic adjustments) with cavitation (sounds) or without cavitation, or were included in a control group. All subjects had their blood drawn before, 20 minutes and two hours after the intervention. Production of IL-2 in mononuclear cell (key element of immune system) cultures was activated with staphylococcal protein A (SPA). Induced secretion of IL-2 increased significantly in manipulation with and without cavitation.
The paper concludes that in vitro T lymphocyte (immune) response to a SPA stimulus became enhanced after spinal manipulation. Therefore, this effect may be independent of joint cavitation/audible. This finding suggests manipulation may influence IL-2 immune-regulated biological responses.
Dr. Wu DC’s comment:
We all know how wonderful chiropractic adjustments can be for sore neck, lower back pain and joint issues. But do you know chiropractic adjustments can also enhance your immune system as well? In this study, researches evaluate effects of upper mid back spinal manipulation (chiropractic adjustment) on the production of interleukin 2 (IL-2) – a key element of innate immune system signal response to foreign body infections such as bacteria, viruses and parasites. IL-2 also play a major role with T-cell-dependent immune response system which helps you to fight off these nasty and gnarly microbial infection. Pretty cool stuff, isn’t it?
