Acupuncture involves stimulation of specific points within the human body through the use of needles. The goal is to achieve physiological effects such as alleviating pain, inflammation or obtaining muscle relaxation. It can be used in orthopedic and sports injuries to assist in accelerating recovery of function and enable patients to proceed to a more intensive form of active exercising. Acupuncture can also be used in chronic pain conditions for pain control or pain relief. Electrical muscle stimulation can also be attached to acupuncture needles to increase therapeutic benefit.
