Sydney: Scientists have discovered that low level laser can help patients with chronic neck pain.
In a trial, published in the International Association for the Study of Pain, a low level laser was used on 90 patients with chronic neck pain. They were treated by reserachers at the University of Sydney, over a period of seven weeks with a course of 14 treatments or a placebo laser.
At the end of the trial the results revealed that pain had decreased in the treated group. Doctors are not sure how the laser lessened pain but have theorised that it may increase the release of the harmony hormone serotonin or stimulate the body’s own pain fighters.
