The Pros and Cons of Cold Laser Therapy


Low level laser therapy, or “cold” laser therapy, is a relatively new medical field. It came into being in the mid sixties, only a few years after the first successful testing of a laser device. Before the laser, most research that focused on the use of light for medical purposes was mostly centered on studying the destructive thermal properties of light and radiation. Cold laser therapy marked one shift in this trend by focusing instead on the non-destructive and non-thermal benefits of light emission.

The Pros

Cold laser therapy was pioneered by a man named Endre Mester, a medical researcher who working out of Semmelweis University in Budapest, Hungary, when in 1967 he successfully demonstrated the capabilities of low level laser light to stimulate cell functions and help expedite tissue repair. Mester’s original goal in conducting these studies into low level laser light was to find an alternative treatment for diabetic ulcers.

In the decades that followed Mester’s founding research, other scientists have continued to explore the potential medical uses of low level laser light using a top quality surgical laser, many of which have yet to be discovered and/or fully explored. Thus far, cold laser therapy has been proven to work effectively in the treatment of neck pain, rheumatoid arthritis, osteoarthritis and carpal tunnel syndrome, and musculatory ailments. Another thing that makes cold laser therapy attractive to many patients is the fact that cold laser therapy is non-invasive, painless and has no negative side effects.

The Cons

The main downside to cold laser therapy is that it is still a relatively new medical field, and as such, has not been accepted widely into the mainstream scientific and medical community. As a result, there is a lack of sufficient data and properly-conducted studies to verify the benefits of cold laser therapy in the treatment of certain diseases. Nonetheless, unethical medical companies will sometimes advertise these unproven treatments anyway, which is why it’s important to look if the treatment has FDA approval before you purchase it. The FDA, despite having officially approved a wide variety of cold laser therapy treatments, still considers it an experimental field.
