A chiropractic adjustment is the art of introducing a specific force in a precise direction, applied to a vertebra that is subluxated or out of place. The Chiropractor identifies the location of the subluxation, determines the exact direction and the best way to correct the positioning. The adjustment itself is a movement of the spine that is done either by hand or with an instrument. The movement may be quick or may be undetectable with low force techniques. The adjustment assists the vertebra back into normal alignment and restores proper motion in order to relieve nerve interference. There are many ways to analyze and adjust the spine, so the actual adjustment will vary from chiropractor to chiropractor and patient to patient.
