A specific method of adjusting that utilizes an instrument delivering a mechanically determined amount of low force as treatment. The chiropractor uses an instrument called an Activator to make your adjustment. It is a small hand held impact tool in which a quick snap is applied to correct a vertebral mis-alignment according to a set pattern. Activator uses various movements and tests to determine where the subluxation is. Correction is made using the Activator Adjusting Instrument to give consistent low-force, high-speed chiropractic adjustments rather than directly by hand

The handheld Activator instrument is specifically designed to deliver a controlled, light and fast thrust without undue strain to the patient. The thrust delivered by the instrument is so quick that it accelerates ahead of the body's tendency to tighten up and resist the thrust of an adjustment.
