Acupuncture is an ancient treatment, and many of the older acupuncture traditions and beliefs are now thought to be irrelevant. Although the modern medical world is devided upon how exactly acupuncture works, many modern studies have shown that acupuncture relieves pain. The latest theory suggests that needling the acupuncture points stimulates the nervous system to release chemicals in the muscles, spinal cord, and brain. These chemicals will either change the experience of pain, or they will trigger the release of other chemicals and hormones which influence the body’s own internal regulating system.

Acupuncture is widely used in the treatment of stroke rehabilitation, headache, menstrual cramps, tennis elbow, fibromyalgia, myofascial pain, osteoarthritis, low-back pain, carpal tunnel syndrome, and many other conditions. Recent studies have demonstrated pain relief and improved function for people with osteoarthritis of the knee.
