Cold laser therapy, also known as low-level laser therapy (LLLT) or photobiomodulation therapy, is a non-invasive medical treatment that involves the use of low-level lasers or light-emitting diodes (LEDs) to stimulate healing and reduce pain and inflammation in various parts of the body. Chiropractors, among other healthcare providers, may offer cold laser therapy as part of their treatment options for musculoskeletal conditions.
Here’s How Cold Laser Therapy Works:
- Device: A cold laser therapy device emits specific wavelengths of light, typically in the red or near-infrared spectrum. These wavelengths are believed to penetrate the skin and underlying tissues without causing heat or damage.
- Application: The chiropractor will direct the cold laser device over the area of the body that requires treatment. The light is usually applied directly to the skin, but it can also be applied through clothing if necessary.
- Absorption: The body’s cells absorb the light energy. This light energy is thought to stimulate the mitochondria, which are the energy-producing powerhouses of cells. This stimulation is believed to increase cellular energy production and promote healing.
- Biological Effects: The exact mechanisms by which cold laser therapy works are not fully understood, but it is thought to have several biological effects, including:
- Reduced Inflammation: Cold laser therapy may reduce inflammation by inhibiting the production of inflammatory molecules and promoting the release of anti-inflammatory substances.
- Pain Relief: It can help alleviate pain by blocking pain signals and promoting the release of endorphins, which are natural painkillers.
- Tissue Repair: Cold laser therapy is believed to accelerate tissue repair and regeneration by stimulating collagen production and enhancing blood flow to the treated area.
- Muscle Relaxation: It may help relax tight muscles and improve range of motion in joints.
