The theory and practice of acupuncture originated in China. Acupuncture points are specific anatomically defined areas on the skin. They were originally described as holes in the skin through which qi energy could flow. Electrodermal measurements can help to accurately detect acupoints.
Acupuncture points are believed to stimulate the central nervous system and thereby release chemicals into the spinal cord, muscles, and brain. These biochemical processes may then stimulate the body’s natural healing abilities and, as a result, promote physical and emotional well-being.
A study on 49 patients with knee osteoarthritis found that the short-term application of LLLT to specific acupuncture points can help to reduce pain and improve the quality of life in patients.
