The Activator Method is a device-assisted form of performing a chiropractic adjustment. The Activator Method is one of the most widely-researched chiropractic techniques, and the only instrument adjusting technique with 23 clinical trials to support its efficacy. Activator Methods has published hundreds of clinical and scientific peer-reviewed papers, worked with major academic research institutions, and received grants from recognized entities like the National Institute of Health. 

Chiropractic adjustments involve applying forces at specific spinal levels to release the tension caused by a misaligned segment. It was shown that the Activator is able to provide 1mm of movement to a spinal segment where as a manual adjustment was shown to only  deliver 2% of the total force to the target tissue. The Activator is able to provide an adjustment up to 300 times faster than a manual adjustment, which results in the ability to deliver a gentler adjustment over a smaller area in order to more properly move the bones to promote healing.
