What causes a subluxation?

A fall, injury, sudden jar, trauma, or sometimes an inherited spinal weakness can displace a vertebra. Other causes include improper sleeping conditions or habits, poor posture, occupational hazards, incorrect lifting practices, obesity, lack of rest and exercise, and stress. The word "subluxation" comes from the Latin words meaning "to dislocate" (luxate) and "somewhat or slightly" (sub). A subluxation means a slight dislocation (misalignment) or biomechanical malfunctioning of the vertebrae (bones of the spine). These disturbances may irritate nerve roots and blood vessels which branch off from the spinal cord between each of the vertebrae. This irritation may cause pain and dysfunction in muscle, lymphatic and organ tissue as well as imbalance in the normal body processes.
