What Is Cold Laser Therapy?

Cold Laser Therapy utilizes low-intensity laser light to stimulate healing in damaged tissue. Though not actually “Cold”, this therapy gets its name because Cold Laser Emitting Devices do not emit intense enough light to burn tissue, unlike the lasers used during surgeries to burn away tumors and other harmful tissues.

How Does Cold Laser Therapy Work?

Mechanism of Action:

During Cold Laser Therapy, a specialist applies different levels of low light wavelengths directly into a targeted area. The muscle tissues in the body then absorb the projected light. The red light causes a warming reaction at the near-infrared level, and the damaged muscle cells respond with a physiological reaction that promotes blood flow, accelerating cellular regeneration.

Specialists commonly treat superficial tissue with laser wavelengths between 600 and 700 nanometers (nm). The physician will use wavelengths between 780 and 950 nm to reach deeper tissues.

Although patients will feel the physical laser device touching their skin, the procedure does not cause pain or require surgery. The device produces no noise or vibrations, and each treatment typically takes only a few minutes.

Potential Applications: Cold laser therapy is used to address a range of conditions, including:

  1. Muscle and Joint Pain: It’s often used to alleviate pain and inflammation associated with osteoarthritis, rheumatoid arthritis, tendonitis, and bursitis.
  2. Injuries: Cold laser therapy may be used to promote healing in sports injuries, sprains, strains, and soft tissue injuries.
  3. Neck and Back Pain: It can be applied to reduce pain and discomfort in the neck and back caused by various factors.
  4. Wound Healing: Cold laser therapy may accelerate wound healing, including non-healing ulcers.
  5. Nerve Pain: Some studies suggest that it might help manage nerve-related pain like neuropathy.
  6. Dermatological Conditions: Cold laser therapy may be used for certain skin conditions, such as psoriasis and acne.

What Are The Benefits And Effects Of Cold Laser Therapy?

    • Pain Relief: It can help reduce pain by inhibiting nerve conduction, reducing inflammation, and promoting the release of endorphins (natural pain-relieving substances).
    • Inflammation Reduction: Cold laser therapy has anti-inflammatory effects, helping to reduce swelling, redness, and heat associated with acute or chronic inflammation.
    • Tissue Repair and Regeneration: The increased cellular energy production and metabolism stimulated by cold laser therapy can enhance tissue repair, accelerate wound healing, and promote the formation of new blood vessels (angiogenesis).
    • Improved Circulation: Cold laser therapy may improve blood circulation and lymphatic flow, facilitating the removal of waste products and enhancing nutrient and oxygen supply to the treated area.

It’s important to note that while cold laser therapy is used for various conditions, its effectiveness can vary based on factors such as the specific condition, the individual’s response, and the treatment protocol used. If you’re considering cold laser therapy, consult with a healthcare provider to determine if it’s appropriate for your specific needs and to ensure that you receive proper guidance and treatment.
