Therapeutic laser, or low-level laser therapy, is a non-invasive treatment that uses light to promote healing and reduce pain and inflammation. It is backed by scientific evidence for various conditions, particularly in pain management and wound healing. Therapeutic lasers work through a process called photobiomodulation. This involves the absorption of specific wavelengths of light by cellular components, leading to several biological effects including increased ATP production, enhanced cell metabolism, reduction of inflammation, pain reduction and improved blood flow. Laser treatment can also be used to stimulate acupuncture points that may be too sensitive or for patients that do not tolerate needle insertion.
