Wound Healing with Laser Light Therapy

Chronic wounds are a major source of disability for many people. They are notoriously difficult to treat with standard protocols. Often chronic wounds occur on the feet and lower limbs as a result of poor circulation. Diabetes and atherosclerosis are common contributing factors. Laser therapy has been proven to speed healing and resolution of skin ulcers and chronic wounds. An analysis of the research on laser therapy allowed researchers at the University of Johannesburg to conclude:

“Low level laser therapy (LLLT) is a form of phototherapy that involves the application of low power … light to injuries and lesions. It has been used successfully to induce wound healing in nonhealing defects. Other wounds treated with lasers include burns, amputation injuries, skin grafts, infected wounds, and post-surgical wounds. The unique properties of lasers create an enormous potential for specific therapy of skin diseases.”

A triple blind study at Brigham Young University concluded that:

“The laser therapy resulted in enhanced healing as measured by wound contraction. These data indicate that laser therapy is an effective modality to facilitate wound contraction of partial-thickness wounds.”

Harvard Medical School, Department of Dermatology has been researching laser therapy extensively. In a published paper researchers state:

Our laboratory has shown that a single exposure to red or near-IR wavelengths 30 minutes after wounding can stimulate wound healing in mice. Specifically, the light appears to hasten the contraction process at the edges of the excisional wound.

In my naturopathic medical clinic I have been treating patients with a high end laser therapy machine for two years and have had the opportunity to help patients heal wounds that previously wouldn’t heal. One such patient, a 60-year-old man with diabetes, had a longstanding wound on the bottom of his foot the size and depth of two stacked toonies. After a series of treatments, the wound healed completely. Six months later, the wound remained healed, and laser therapy quickly healed up another wound that was starting. The patient was able to increase his activity level, go traveling and enjoy life again.

Laser therapy is a painless treatment used to heal tissues throughout the body too. It is an excellent way to speed the healing of back pain, sports injuries, arthritis, plantar fasciitis (foot pain), tendonitis, shoulder pain and more. It works by increasing the output of fuel within the cells. Specific wavelengths of light, emitted by the machine, can be absorbed by photoreceptors in the body’s cells. Photons are then transmuted into ATP, which is the fuel for the cells. Also, cell membranes become more permeable to nutrients. Thus, with added energy and fuel, cellular function is enhanced. Nitric oxide is also increased, which increases circulation. The net effect is less inflammation and rapid healing of tissue creating a real resolution of the problem. The results are quite visible in the case of wound healing and there has been photo documentation of many dramatic resolutions of gangrenous toes that were able to be saved from amputation.

Naturopathic physician, Dr. Deidre Macdonald is pleased to announce the arrival to the Comox Valley of a high tech solution for people suffering from spinal, joint and muscle pain. Low level laser therapy is the technology that caught her attention when it healed a back problem she had suffered with for six years. Dr. Macdonald said, “The results I got after a few treatments were better than I had received from the 13 practitioners from whom I had sought treatment previously.” The good news for pain sufferers is that with the painless approach of laser light, rapid healing occurs. Dramatic healing can be seen when laser light is applied to wounds such as diabetic leg ulcers, large bruises, burns and other stubborn wounds. The same tissue healing can be felt for people suffering from tendonitis, back pain, carpal tunnel syndrome, ligament issues, disc herniation, bursitis, plantar fasciitis, osteo and rheumatoid arthritis and post surgical recovery. Dr. Macdonald notes that “when I started looking into this technology I was impressed that there have been 1,200 scientific studies done on it over 50 years. Excellent results are being achieved particularly with new breakthroughs in the technology. The laser machine I settled on is truly state of the art. Unlike most laser machines, it has 2 large wrap-around treatment heads with 120 laser diodes each, enabling fast and powerful treatment of larger areas than the traditional older single laser units.”

This technology uses superluminous and laser diodes to bathe abnormal tissue with photons. Photons are particles of energy that are absorbed by a variety of components within the cell, a process which initiates a number of positive physiological responses. In essence, light energy is converted into biochemical energy. The therapeutic light beam permits penetration of deep tissues without adversely affecting normal cells. The body’s natural healing processes are enhanced and tissues heal. The process is curative and as logic dictates, symptoms disappear.

The Theralase laser device used in Dr. Deidre Macdonald’s naturopathic medical clinic is Health Canada approved and is used in hospital physiotherapy clinics and burn units around the world. The therapy is non-invasive, painless, non-toxic, highly effective and there are no known side effects. Numerous scientific studies have pinpointed the mechanism by which it speeds healing. The specific frequencies of laser light used cause an:

ATP production is increased resulting in improved cellular energy and metabolism

  • Mitochondrial activity is stimulated resulting in cell replication etc. (ie replacement, regeneration and repair of abnormal cells)
  • DNA production; protein building block of tissue is substantially increased
  • Neurotransmission is facilitated due to elevated levels of serotonin and acetylcholine
  • Modulation of macrophages, fibroblasts and other cells
  • Angiogenesis (formation of new blood vessels) improves blood supply to healing tissue
  • Regulates cell membrane potential, essential in Na, Cl, and K ion transfer (electrolyte balance)
  • Cytokines and other chemicals enhancing cellular communications are released

To find out more about this state of the art laser device call for a complimentary 15 minute introductory evaluation with Dr. Macdonald at (250) 897-0235.
