Laser is an acronym for Light Amplification by Stimulated Emission of Radiation.
The radiation generated by the therapeutic devices differs from that produced by the other similar sources in the following three respect.
1. Mono-chromaticity: The light produced by the laser is single colored the majority of radiation emitted by the treatment device is clustered around single wavelength with very narrow bandwidth.
2. Collimation: The laser light i.e. the photon produced by laser devices are for all practical purposes parallel with almost no divergence of the emitted radiation over distance.
3. Coherence: The light emitted by laser device are in phase i.e. trough and peaks of emitted light waves match perfectly in space(spatial coherence)and time(temporal coherence).
While laser therapy dates back to 1960's, the Unites States Food and Drug Administration (US FDA) did not approve lasers until 2002. However, Europeans have been using therapy lasers much longer than in the US.
When applied by a certified, properly trained professional, Laser treatments are extremely safe. At Pain Management Centers, we take all precautions to ensure that patient is never at risk, staying away from the eyes, thyroid, and other sensitive areas. This treatment is safe to give over broken skin, acute injuries, and metal implants. Laser therapy is non-invasive and drug-free.
The number of sessions will depend on the exact diagnosis, age and overall health status of the patient and some other factors. In general, acute conditions can be treated more frequently and require fewer visits, typically 4-6. Chronic conditions may require more visits. Of course, every person responds to Laser treatments differently, so you will need to listen to the advice of Pain Management Center consultants/therapist.
Typically, treatments last 5 to 10 minutes, depending on the size of the area that is being treated.
No. The goal of Laser is to correct abnormalities and allow the body to heal. While you will need numerous treatments, you should feel better and have less pain upon completion.
Yes. Laser is often used in conjunction with other forms of treatment, including physical therapy, massage, chiropractic adjustments, electrotherapy, and even after surgery.
Phototherapy uses light energy from low level Laser’s or SLD’s to elicit biological responses in the body.The effects of phototherapy on tissue are commonly reffered to as photostimulation or biomodulation.

How does Photobiomodulation reduce pain?
- Increase in beta endorphins
- Increased nitric oxide production
- Decreased bradykinin levels
- Ion channel normalization
- Blocked depolarization of C-fiber afferent nerves
- Increased nerve cell action potentials
- Increased release of acetylcholine
- Axonal sprouting and nerve cell regeneration
How does Photobiomodulation reduce pain ?
2. All 4 stages of healing are affected (inflammation, proliferation, remodeling and maturation).
3. Increased fibroblast proliferation in that we see increases in fibroblast numbers and fibroblast-mediated collagen production/
4. Two-five fold increases in growth factor and growth-phase specific DNA synthesis in normal fibroblasts, muscle cells and osteoblasts and mucosal epithelial cells. Increases in fibroblast growth factor (FGF-2) are also seen.
5. Greater healed wound tensile strength in soft tissue and connective injuries.
