The Activator Technique is a device-assisted method of spinal and joint manipulation. Categorized as a mechanical force manual assisted (MFMA) instrument, the Activator Technique consists of a small handheld device known as an Activator Adjusting Instrument (AAI), or more simply, an Activator.
Also referred to as the Activator Method Chiropractic Technique, the Activator Technique delivers controlled and reproducible impulse force to vertebrae (the small bones that make up the spine) as well as the joints that connect them. While originally the Chiropractic Activator was a spring-loaded instrument, it has evolved into an electronic tool which delivers a mechanical force. Both forms of the instrument are known for delivering targeted and gentle impulses to the spine.
