Recent surveys by the National Board of Chiropractic Examiners show that AMCT is one of the two most widely used chiropractic techniques in the United States. Approximately 45,000 doctors of chiropractic throughout the world now use this technique. chiropractic colleges and is offered at international chiropractic colleges.

The primary indicator of lesion and response to treatment is the difference in leg lengths of the prone patient.ĪMCT is taught in the majority of U.S. With detection, treatment is provided through a mechanical instrument designed to deliver a preset amount of force precisely to correct the lesion. Key words: chiropractic, clinical protocol, leg length inequality, researchĪCTIVATOR METHODS Chiropractic Technique (AMCT) is based on a dynamic approach to spinal and somatic dysfunction in which biomechanical lesions are isolated and identified through patient movements designed to isolate and reveal the exact areas of dysfunction. Needs for future research directions are also discussed. As with all spinal manipulative and other therapies, risks of adverse effects exist, but appear to be minimized due to force and velocity characteristics of the AAI. In comparison to other techniques, AMCT appears equivalent to various hands-on approaches, but with less physical demand on the doctor of chiropractic. Summary: AMCT and the AAI represent a system and mode of delivery based on rational and empirical evidence that continues to be informed by an active and growing body of clinical research. Included are basic science research in biomechanics, neurophysiology, and clinical research in AMCT analysis reliability, case studies, prospective cohorts, randomized group clinical outcomes, and comparisons to hands-only treatments. Method: Activator history and associated body of research literature on both the technique and the instrument are critically reviewed. History and development of the technique and its evidence basis and safety issues are discussed. Purpose: A review of the Activator Methods chiropractic technique (AMCT) and Activator adjusting instrument (AAI) is presented.
