What is a laser therapy?

Laser therapies are medical treatments that use focused light. Unlike most light sources, light from a laser (which stands for l ight a mplification by s timulated e mission of r adiation) is tuned to specific wavelengths. This allows it to be focused into powerful beams. Laser light is so intense that it can be used to shape diamonds or cut steel.

Are cold laser therapy devices effective?

Cold laser therapy devices are a convenient way to treat pain, either chronic (like arthritis and TMJ) or acute (like sprains, strains, and other injuries). While they're not a one-and-done solution, they can be an effective option for people who want to speed their recovery processes along at home.

What types of injuries can Laser Therapy treat?

Soft tissue and sports injuries such as muscle strains and ligament strains. Tissue repair and wound healing such as burns and ulcers. Regeneration of nerves e.g. the treatment of Bell?s Palsy (paralysis of one side of the face). Laser therapy can be used for a wide range of conditions and will help reduce pain and inflammation following injury.

How does laser therapy work?

Laser therapy techniques vary based on the procedure. If a tumor is being treated, an endoscope (a thin, lighted, flexible tube) may be used to direct the laser and view tissues inside the body. The endoscope is inserted through an opening in the body, such as the mouth. Then, the surgeon aims the laser and shrinks or destroys the tumor.

What is low level laser therapy?

A laser light is monochromatic, collimated, and coherent. A laser is a device that produces such a light. Low level laser therapy (LLLT) is used by some physiotherapists to treat various musculoskeletal condition. LLLT is a non-invasive light source treatment that generates a single wavelength of light. It emits no heat, sound, or vibration.

What are the different types of laser treatments?

Different lasers are used for different procedures. For example, carbon dioxide (CO 2) lasers make shallow cuts. They’re often used for superficial cancers, such as skin cancer. Argon lasers also make shallow cuts and can be used to activate photosensitizing (light-activated) drugs during photodynamic therapy.
