Chiropractic adjustment is a procedure in which trained specialists (chiropractors) use their hands or a small instrument to apply a controlled, sudden force to a spinal joint. The goal of chiropractic adjustment, also known as spinal manipulation, is to correct structural alignment and improve your body's physical function. Low back pain, neck pain and headache are the most common problems for which people seek chiropractic adjustment. Not only can chiropractic adjustments help relieve back and neck pain, they can also help with the following: sciatica, headaches, colic and ear infections, blood pressure, neurological conditions, frozen shoulder, scoliosis and athletic performance.
