Low-intensity or ‘cold’ lasers are used to stimulate acupuncture points, and are non-invasive and guaranteed pain-free. They can be used closer to a wound than acupuncture needles, making them a good addition to an acupuncture treatment for wound healing. Lasers have also been shown to be anti-inflammatory and analgesic (pain-relieving).
How does it work?
The laser emits red monochromatic light (wave length 660nm). As this light is absorbed into the body, it gives off energy as electrical energy, i.e. photovoltaic effect, and this stimulates the acupuncture point.
Acupuncture points on the skin are stimulated. These sites differ from surrounding tissue in several ways [see: ACUPUNCTURE]. When these points are stimulated, nerve cells send a message to the brain, which can then result in the brain releasing pain-relieving chemicals.
