A term used to describe the highly specific process of manipulating of a body part, typically a joint, with a specific intention, such as to restore or normalize or produce an effect. An adjustment may be direct, as in applied to the actual level of interest, or indirect, as in applied to the opposite side of the structure or to a segment of the region above or below, again for a specific intention. Adjusting maneuvers can produce a sound, or popping release, which is not necessarily meaningful other than to suggest that rapid distraction has occurred. Often, Chiropractic adjustments are described as being a applied with HVLA, or High Velocity Low Amplitude technique. Other adjustments or manipulation can be reduced force or non-force.
