A Brief History of Laser Treatment
Cold laser treatment, also known as low-level laser treatment (LLLT), uses non-thermal lasers to stimulate and enhance the body's natural healing process. Unlike traditional hot lasers used in surgery which cut or burn tissue, cold lasers utilize low power lasers which emit non-heat producing light to aid in reducing pain and inflammation.
The therapeutic use of lasers was first explored in the 1960s by Hungarian scientist Mester and colleagues who discovered that exposure to low-power lasers produced a biological response in cell cultures and animal models. Since then, extensive research over several decades has demonstrated cold laser treatment to be an effective treatment for a wide variety of soft tissue injuries and medical conditions. It has gained popularity as an alternative to medications and surgery due to its non-invasive nature and lack of side effects.
How Does Cold Laser Treatment Work?
While the exact mechanisms are still being researched, it is understood that cold laser Therapy light is absorbed by specific pigments within cells called cytochromes. This stimulates cellular activity which triggers a cascade of biochemical and physiological changes. Some key ways it works include:
- Reducing Inflammation: Laser light stimulates the body's production of anti-inflammatory enzymes which aid in reducing swelling, pain, and healing time.
- Increased Blood Flow: Laser treatment causes vascular changes that improves microcirculation which speeds delivery of nutrients and removal of waste from injured tissues.
- Cellular Repair: Laser light stimulates cellular metabolism which accelerates DNA/RNA synthesis and collagen/protein production allowing for faster tissue repair and regeneration of muscles and nerves.
- Pain Relief: Increased production of endorphins, the body's natural painkillers, help reduce pain sensation. Laser treatment also may block pain signals from being transmitted.
Conditions Treated with Cold Laser Treatment
Due to its many therapeutic benefits, cold laser treatment is being used to successfully treat a variety of musculoskeletal conditions:
- Soft Tissue Injuries: Sprains, strains, contusions, tendonitis are common conditions treated with cold laser treatment to speed healing.
- Joint/Muscle Pain: Arthritis, bursitis, fibromyalgia respond well as laser reduces inflammation and increases mobility.
- Post-Surgical Recovery: Cold laser promotes faster wound healing and reduces swelling/pain after procedures like dental work or cosmetic surgery.
- Neurological Disorders: Conditions like Trigeminal Neuralgia, shingles, and peripheral neuropathy see relief from laser treatment's ability to modulate nerve function.
- Dental/Oral Issues: Toothaches, gum disease, TMJ dysfunction are commonly treated in dentistry using cold laser treatment.
- Skin Conditions: Laser treatment aids chronic wounds, ulcerations, and reduces acne/scarring by stimulating collagen production and blood flow to injured skin tissues.
