It was noted that “enhanced active inhibition” of the sympathetic nervous system tone occurred in every post-adjustment measurement! This study was placebo controlled, and were able to undeniably prove that it clearly wasn’t a placebo effect or just “laying on of hands”. In some studies there were placebo controlled groups who received sham adjustments, and those who were set up for an adjustment, brought to tension and leaned into, but the high velocity low amplitude thrust was not made. As you would guess, these groups fMRI reflected no cortical neuroplastic change. So what’s the point?
The bottom line here is that the vertebral subluxation or misalignment of the spine, caused by chronic poor posture damage, or acute sudden traumatic damage like a fender-bender, or sports injury, leads to a overload on the central nervous system. What occurs in the brain is the bombardmentwith afferent signals from joints and surrounding muscles. It’s as if the body is trying to alert the nerve system, “Houston, we have a problem! I’m not moving correctly!” (much like a tracton warning light signal coming on in your car). A chiropractic adjustment reduces these excessive signals and improves altered input into the CNS, resulting in better adaptation to any internal or external stimuli. Improving brain adaptability is one of the most important areas of study today in all of healthcare, and especially for sports performance, and health related quality of life!
