Activator technique

The Activator Method Chiropractic Technique is a chiropractic treatment method that uses a device created by Arlan Fuhr as an alternative to manual manipulation of the spine or extremity joints. The device is categorized as a mechanical force manual assisted (MFMA) instrument which is generally regarded as a softer chiropractic treatment technique. The method purports to use the device to identify and remove vertebral subluxations and correct "pelvic deficiency", defined as an "'apparent' difference in leg length, not an anatomical difference". These claims have been criticized.
