In 1994 the Activator II was first released when research at the University of Vermont found that when the initial instrument was given an impedance head it produced a 'significant improvement in the frequency content' of the force delivered to the spine. Īctivator I was the first product patented by Activator Methods International on September 26, 1978. The design of the tool was based on a dental impactor. The aim is to produce enough force to move the vertebrae, but not enough to cause injury. It was found to give off no more than 0.3 J of kinetic energy in a 3-millisecond pulse. With the release of the Activator V this process has changed from a spring-loaded grip to an electronic tool which delivers the mechanical force.
The traditional Activator Adjusting Instrument (AAI), or more simply, Activator, is a small handheld spring-loaded instrument which delivers a controlled and reproducible impulse to the spine.
