Laser Therapy involves using low levels of light to promote healing. This method may be referred to as ‘cold laser therapy’ as the low light level doesn’t heat the patient’s tissue as opposed to surgical and aesthetic lasers which use heat on the tissues to destroy tumors and coagulate body tissue.
Varying wavelengths and different intensities of low level light are directed to the damaged or injured area of the body. The patient’s tissue will absorb the light and the red and nearly infrared light generate a response within the damaged cells which promotes the cells to regenerate.
The patient may be aware of the laser touching their skin, however the laser therapy is quiet, painless and noninvasive. Typically superficial tissue is targeted with wavelengths between 600 and 700 nanometers, and for deep tissue wavelengths will be between 780 and 950 nanometers.
