History Of Laser Therapy

In June of 1905, over a century ago, Albert Einstein published the theory of relativity. He discovered that light had some special properties. Einstein’s, theory of the photoelectric effect laid the foundation of what was to come. Scientists started to understand what light could really do! On May 6, 1960, Theodore H. Maiman changed the world. At his lab in the research facilities of Hughes Aircraft company in California, Maiman made a homemade high-voltage power supply that was able to shoot a light through a small tubular ruby-made device. This caused a pulse of powerful red light to be projected as a spot on the wall. This day marked the invention of the laser.

In 1967, seven years after the first working laser was invented, a physician named Endre Mester, a professor at the Semmelweis Medical University in Hungary, discovered something amazing. He was trying to follow an experiment first published by an American scientist, Paul McGuff. This experiment was to use the ruby laser to treat tumors in rodents. Mester’s custom-made ruby laser had only a fraction of the power compared to McGuff’s. Throughout this experiment, Mester noticed that this low-powered ruby laser had accelerated the rate of hair growth and increased wound healing in the mice. Mester had discovered the positive biological-effects of low power lasers, soon to be known as Photobiomodulation.

Since this discovery, laser therapy has been a world changing topic in the field of medicine. It started to be used as an alternative medicine in wound healing, physical rehabilitation, and musculoskeletal conditions. Over the last 60 years, there have been more then 15,000 published medical research papers on the subjects of laser therapy, Photobiomodulation, and the effects of low-level lasers.

Science & Benefits

Class IV Laser Therapy can help decrease inflammation and pain in acute, chronic, superficial, or deep conditions by increasing circulation and enhancing tissue repair. Laser therapy does so by delivering specific red and near-infrared wavelengths of laser light to induce a photochemical reaction and therapeutic effect. It is a preferred choice for practitioners worldwide, and Summus Medical Laser® was cleared by the United States Food and Drug Administration (FDA) in 2005.

What Patients Are Saying 

I am giving this laser 5* after one treatment. Long story short… after breast lift/ reduction, I had a large open wound where stitches separated from pressure/ previous scar tissue. In just ONE treatment my wound is 50% healed in 24 hours. Literally amazing. My wound was about 2 to 3 inches in diameter. I am anxiously awaiting my next treatment.

It was a life saver. I was in incredible pain and had numbness and tingling. It was totally gone and has not returned. It took only 5 short pain free treatments!!!

Your laser has literally saved my life! After 11 assorted spine surgeries and 3 total left knee replacements I can breathe again thanks to your laser.

Within hours I had regained at least 60% mobility with no pain. Five days later I returned for the second laser treatment and was amazed that within two hours of the treatment I had regained 100% mobility without pain. The next morning I did my daughter’s hair without crying.

Frequently Asked Questions
Does it hurt? What does a treatment feel like?

There is little or no sensation during treatment. Occasionally, the patient feels mild, soothing warmth, or tingling sensations. Areas of pain or inflammation may be sensitive briefly before pain reduction.

Are there any side effects or associated risks?

During more than twenty years of use by healthcare providers all over the world, very few side effects have ever been reported. Occasionally, some old injuries or pain syndromes may feel aggravated for a few days as the healing response is more active after treatment.

How often should a patient receive laser therapy?

Acute conditions may be treated daily, particularly if they are accompanied by significant pain. More chronic problems respond better when treatments are received 2 to 3 times a week, tapering to once every week or two as improvement is seen.  

How many laser therapy treatments does it take?

This depends on the nature of the condition being treated. For some acute conditions 4 to 6 treatments may be sufficient. Those of a more chronic nature may require 6 to 12 (or more) treatments. Conditions such as severe arthritis may require ongoing periodic care to control pain.

How long before results are felt from laser therapy?

You may feel improvement in your condition (usually pain reduction) after the very first treatment. Sometimes you will not feel improvement for a number of treatments. This does not mean that the condition is not improving. Each treatment is cumulative and results are often felt after 3 or 4 sessions.
