Photobiomodulation, cold laser therapy, low-intensity light therapy, and soft laser therapy are all terms used to describe low-level laser therapy (LLLT). The use of these types of applications has been proven to have excellent pain-relieving properties, as well as the ability to improve the functioning of different cells. In order to achieve the desired effect, one must stay within specific wavelengths of light. LLLT will not be effective at lower levels if it is applied at lower doses and ranges. Several acute and chronic conditions may benefit from LLLT. Numerous medical conditions and their associated symptoms have been successfully treated with LLLT. LLLT has anti-inflammatory, pain-relieving, edema-reducing, and healing-promoting properties regardless of the condition it is used for. Researchers have shown that this therapeutic solution reduces short-term pain in rheumatic conditions (rheumatoid arthritis, osteoarthritis), neck pain, joint disorders (chronic), and tendinopathies. A variety of musculoskeletal conditions, including carpal tunnel syndrome and fibromyalgia, have been successfully treated with it. LLLT can improve overall function for those suffering from temporomandibular joint disorders and more.
