Statement of Intent:
Activator Methods Chiropractic Technique (AMCT) seeks to conduct a systematic analysis of basic body biomechanics, under the general belief that disturbed mechanics leads to disturbed function. A series of diagnostic provocative maneuvers and leg checks are used to identify the location of subluxation; the therapeutic goal is to restore proper body mechanics through the application of low-force adjustments. The use of the activator adjusting instrument is thought to promote increased safety for patient and doctor.
According to Fuhr, AMCT is a synthesis of several analytic systems and low-force adjustive procedures, including Logan Basic, Derifield-Thompson leg checking and VanRumpt’s Directional Non-Force Technique (DNFT), the latter of which features thumb thrusts and a system of leg length analysis . Subluxations, detected primarily by the leg check procedure, are addressed with a mechanical percussive tool (Activator Adjusting Instrument or, simply, “Activator”). The leg checking procedure also serves to establish correction of the subluxations.
