Diversified technique (DT) is what most people imagine when they think of chiropractic treatment, and it is the most commonly used adjustment technique by chiropractors.  Diversified technique is characterized by a quick and forceful, but small, thrust or twist of the patient's neck or spine by the chiropractor. DT's objective is to restore proper movement and alignment of the spine and joints.

The Activator Method is an alternative method to manual manipulation, and uses a tool created by Dr. Arlan W. Fuhr, that looks like a doorstop or a small plunger. The device is generally regarded as a low-force chiropractic treatment technique because it does not have the intensity of pressure or the popping sounds that accompany the diversified technique. It is especially helpful for sensitive areas, such as the jaw or arm, and for patients who are more frail.
