Cold laser therapy is a non-surgical treatment. It was first developed in the 1960s. It’s also called low-level laser therapy or (LLLT), soft laser therapy, or photo biomodulation therapy (PBMT).

The technique is called “cold” laser therapy because the level of light is low as compared to other forms of laser therapy, such as those used to destroy tumors and coagulate tissue. Cold laser therapy has been used for decades for knee pain relief. Cold laser therapy is low-intensity laser therapy that stimulates the healing of pain.



During the Cold Laser Therapy procedure, the light energy of different wavelengths is applied directly to a targeted area on the skin. The body tissue then absorbs light. This low level of energy doesn’t heat or cut your skin.

The light beams are placed directly over the injured area for 30 to 60 seconds. This procedure is painless and noninvasive. Also, there is no sound effect and feel of specific vibration or heat. You will need more than one treatment to get the best result. For every treatment, it typically takes only a few minutes. The specific wavelengths of light interact with tissue and accelerate the healing process. Cold Laser Therapy eliminates pain, swelling, and reduces spasms.
