Chiropractic Adjustment (aka Spinal Adjustment) is the most common therapeutic procedure performed by doctors of chiropractic. The purpose of chiropractic adjusting is to restore joint mobility by manually applying a controlled force into joints that have become hypomobile – or restricted in their movement – because of a tissue injury. Tissue injury can be caused by a single traumatic event, such as improper lifting of a heavy object, or through repetitive stresses, such as sitting in an awkward position with poor spinal posture for an extended period. In either case, injured tissues undergo physical and chemical changes that can cause inflammation, pain, and diminished function for an individual. An adjustment to the affected joint and tissues, restores mobility, thereby alleviating pain and muscle tightness, allowing tissues to heal.
