Low Level Laser Therapy - Introduction

Light therapy is one of the oldest methods of treatment. Already in Ancient Egypt sunlight irradiation was used to treat wounds of injured soldiers. In the XIX century different forms of light therapy were widely used, and extracorporeal ultraviolet blood irradiation therapy was developed in the beginning of the XX century. The new era for light therapy started after the creation of lasers.

The biological effects of low level laser light irradiation were first discovered and researched by Endre Mester and colleagues in the 60-s, soon after the development of lasers. The first low level laser therapy systems were based on HeNe (632.8 nm) lasers. Currently diode lasers are replacing HeNe lasers. Diode lasers are small, simple in maintenance, inexpensive in application and have a long lifespan. Red and infrared lasers are generally used for low level laser therapy (LLLT). There are reports about clinical trials of application of laser light of other colors, mainly blue and ultraviolet laser light, but at the moment such systems are not widely used. Light therapy with application of LED light instead of laser light (LED therapy) is another novel method of therapy.

The influence of low level laser irradiation on the organism has several clinical and biological effects, including anti-inflammatory, immunostimulatory, neurotrophic, analgesic, desensitizing, bactericidal, antioedemic, normalizing the blood rheology and hemodynamics effects (depending the condition of the patient and the pathology). Accordingly LLLT can be applied for the therapy of several pathologic conditions in various branches of medicine, including disorders and diseases of the

musculoskeletal system - osteochondrosis, back pain, arthritis, disorders and traumatic injuries of muscles and ligaments;
cardiovascular system - ischemic heart disease, stenocardia, myocardial infarction, hypertension, atherosclerosis;
ENT organs - chronic inflammation of accessory nasal sinus, pharyngolaryngitis, tonsillitis, otitis, rhinitis, hearing loss, Menier's syndrome;
gastrointestinal and digestion system -
peptic ulcer of the stomach and duodenum, dyskinesia of the gallbladder and biliary duct, colitis, chronic pancreatitis, chronic cholecystitis;
skin - dermatitis, dermatosis, neurodermitis;
respiratory system - pneumonia, bronchitis, bronchial asthma;
female reproductive system - adnexitis, vaginitis, disorders of menstrual cycle, some forms of infertility;
renal and urinary system - pyelonephritis, cystitis, prostatitis, prostate enlargement;
nervous system - neuritis and neuralgia of peripheral nerves, neuralgia, facial neuritis, cerebro-vascular insufficiency;
teeth and gums - caries, pulpitis, periodontitis, paradontitis
as well in the therapy of infectious disease (viral hepatitis, tuberculosis, chlamydiasis), for prevention of complications of surgery and many other cases.

Different methods of laser therapy should be applied for the therapy of different patients and pathologies. The main ways of application of laser light include irradiation of skin, mucous membranes, wounds, burns, acupuncture points and blood.
