MODEL RELEASED. Chiropractic. Woman chiropractor presses on and manipulates the spinal column of a female patient. Chiropractic (chiropathy) is based on the theory that disorders may be traced to an incorrect alignment of bones and abnormal nerve functioning. The chiropractor attempts a remedy by removing nerve interference through manual adjustment of the spinal column. Movement of spinal vertebrae may release pressure on a spinal nerve root and have a referred effect on the organ or tissue to which the nerve is connected.
