A chiropractor can perform acupuncture without specialty certification. Acupuncture is one of the many techniques chiropractors are already trained to perform safely and effectively. In fact, because they are trained to fully understand the spine, muscles, and nervous system, they are the best people to turn to for acupuncture therapy. In order to use certain electrotherapy equipment, you must be a licensed chiropractor. An accredited chiropractic program usually takes four years to complete.
