What is Laser Therapy

Low level laser therapy, (LLLT) is a painless, non-invasive, drug-free intervention which is used to treat a wide variety of pain syndromes (arthritis, sciatica, etc.), injuries, neurological conditions and pathologies. This treatment modality was developed in 1985, in Europe and brought to the United States in 1990 and became approved by the Federal Drug Administration in 2002.

How Does Laser Light Heal?

Low level laser supply energy to the body in the form of non-thermal photons of light. Light is transmitted through the skin’s layers (the dermis, epidermis and the subcutaneous tissue or tissue fat under the skin) at all wavelengths in the visible range. However, light waves in the near infrared ranges penetrate the deepest of all light waves in the visible spectrum.

What to Expect During a Laser Therapy Treatment Session

For most people, laser therapy is quite passive. The treatment typically last approximately 2 to 20 minutes in lenght. Following a laser therapy session, approximately 75-80% of patients being treated can notice an immediate improvement in their condition. This will depend primarily on the type of condition and length of time the condition has been present. Generally, the more chronic or severe the condition, the longer it takes for there to be a perceived change in pain.

Difference between Lasers, LED & SLD light devices

Super Luminous Diodes (SLD) or Light Emitting Diodes (LED) does not penetrate all the skin layers. Monochromatic non-coherent light can be helpful for superficial wound healing; however, numerous studies have shown that laser are far more effective due to their unique properties and penetration depth. Many super luminous & light emitting diode products are usually very low powered (typically 5mW-15mW), and much of this energy is scattered, therefore requiring longer treatment times. 830nm can penetrate 5 cm. far more effective then SLD’s or LED’s.
