Chiropractic is a natural system of healthcare and serves the needs of an estimated 20 to 30 million Americans each year. The primary aim of chiropractic care is to restore and maintain health by properly aligning the spine. Although the main method of treatment is spinal manipulation, chiropractors also use other therapies to treat their patients. Listed below are a few of these we recommend consulting with your doctor to find out which treatment is best for you.**Ultrasound**Therapeutic ultrasound is a form of deep heat therapy created by sound vibrations. Sound waves penetrate tissues deep in the body creating a pumping action and heat. This micro massage helps reduce swelling, decrease pain and stiffness and improve blood flow.**Ice**Ice therapy is often used to reduce swelling and pain caused by acute injuries or flare-ups of a chronic condition. Properly applied ice reduces the temperature of the tissues directly on or below the surface of the skin. This cooling numbs painful areas, constricts blood vessels and helps relax muscle spasms.**Heat**Heat, when applied to the skin, enlarges blood vessels below the surface and relaxes muscle tissue. Heat therapy can calm irritated tissues and increase circulation to help speed the healing process.
