Deep Tissue Laser Therapy For Back Pain
Laser therapy is a relatively new therapy in which laser light in the red, infrared and far infrared wavelengths is applied to the surface of the body to enhance healing.
The biological effects of laser were discovered accidentally by Hungarian physician and surgeon Endre Mester in 1967 during an experiment to demonstrate that laser light could reduce tumours in mice. Although he found laser didn’t have any effect on the tumours, he did discover that laser not only regrew hair faster, it also increased the speed of wound healing in mice. We now know that the same effects occur on humans and other animals. This is called photobiomodulation.
After many 1000s of research studies, we now understand most of the biological processes occurring at the cellular and DNA level, when the cell is exposed to light of certain wavelengths.
The laser light penetrates deep into cells and triggers biochemical reactions that increase cellular energy, increase oxygen levels and trigger genes involved in re-growing nerves and other damaged tissues.
Cold vs Hot Lasers
The majority of therapeutic lasers used are commonly known as ‘cold lasers’. These lasers have very low power and for that reason do not generate any heat on the skin. Treatment with these lasers is known as ‘Low Level Laser Therapy” (LLLT).
The lasers we use are ‘hot lasers’. These lasers are much more powerful than cold lasers normally more than 100x more powerful. Therapy with these lasers feels warm and soothing because of the higher energy. This therapy is known as ‘High Intensity Laser Therapy’ (HILT).
Both hot and cold lasers have similar depth of penetration into the body. The depth of penetration is determined by the wavelength of light and not the power. The difference between the two is the time it takes to deliver a therapeutic dose. A 15 watt hot laser will treat an arthritic knee to the point of pain relief, in about 10 minutes. A 150 milliwatt cold laser would take over 16 hours to deliver the same dose.
The amount of energy, wavelength, size of area to be treated and duration of the laser treatment is key to a successful outcome. There is a very fine balance between not enough energy and too much. Not enough energy delivered to the tissues will produce no noticeable change. Too much energy is also not effective because after delivering the optimum dose, the excess energy starts to inhibit healing which again results in no noticeable change.
What can I expect from laser therapy?
Most patients seek laser therapy because they are in pain. It may be from osteoarthritis, frozenshoulder, tennis elbow or many other musculoskeletal conditions. About one third of patients experience a reduction in pain and/or increase in mobility after just one treatment.
The maximum biological effect from the laser occurs shortly after treatment and then diminishes over time. Patients may experience significant pain reduction and improved mobility for a few days then the pain gradually starts to return. This is the best time to have the next treatment.
What does High Intensity Laser Therapy help?
Laser therapy does not heal anything, what it does do is enhance your own body’s ability to heal itself. It does this predominately by increasing energy production within the cells mitochondria.
In an injury, many different cells are working to repair the damage, including white blood cells, red blood cells, platelets and fibroblasts. These energised cells can now work faster and more effectively than before therefore increasing the rate of healing.
What can it treat?
Conditions treated range from osteoarthritis of the knee, hip and ankle, rheumatoid arthritis, shoulder impingement syndromes, hip or shoulder bursitis, low back disc degeneration, disc herniation, sciatica, tendonitis, tennis elbow, plantar fasciitis, neck pain and headaches. In short any injury or degenerative condition that the body is able to heal itself, can potentially be enhanced with laser therapy.
There are a growing number of research papers published in the last 7 years that are demonstrating the efficacy of laser therapy for stroke, Alzheimer’s disease, Parkinsons disease and traumatic brain injury. Larger studies are needed to confirm these positive results.
How often and how long?
The number and frequency of treatments depends on the condition being treated and how long the condition has been present. A long term (10yr history) arthritic knee may take 12-14 treatments before long term pain relief and normal movement are achieved. A rotator cuff tear in the shoulder takes approximately 6-8 treatments. Plantar fasciitis (pain in the heel and sole of foot) normally takes 3-5 treatments. These are just a rough guide and will differ from person to person but they do illustrate the ability of laser to significantly enhance your body’s healing process.
What are the side effects?
As with all treatments there are side effects but the possible negative effects of High Intensity Laser therapy from a treatment are minimal and temporary.
Some patients, about a third, experience an exacerbation of their symptoms shortly after treatment, which does pass, normally in 1-3 days and is often limited to the first couple of treatments. This is because the body’s healing mechanism involves a short term burst of inflammation (acute inflammation). Patients are reassured that inflammation has to take place for a tissue to heal and the flare up does demonstrate that a therapeutic effect is taking place.
Heat causes the area treated to become quite warm. The practitioner moves the laser constantly to prevent discomfort. This is no different to a hairdresser moving the hairdryer constantly to prevent discomfort. Most patients enjoy the feeling of warmth over their injury.
Laser light can be damaging to your eyes, if you look directly at the beam. This is because the lens in our eyes focuses the light coming into the eye on the retina. If we stare at the laser or even the sun without eye protection, damage to the retina and even loss of sight is possible. For this reason, both patient, practitioner and any other person in the treatment room must wear specific eye protection glasses or goggles whilst the laser is in operation.
