Whenever a treatment is not fully understood, there are skeptics. It is good to be skeptical, but an open mind helps too!
Cold lasers do not generate heat. The FDA has approved the technique, and studies have shown it to be an effective short term treatment for pain. However, there are still questions regarding how and why the therapy works.
Multiple studies have demonstrated that low level laser therapy helps relieve pain, sometimes in instances where other methods of pain relief have not worked.
The range of options for treatment have caused some questions, as LLLT can include a variety of wavelengths, intensities, number of treatments, and other variables. In simple terms, light causes a photochemical response in the cells, particularly the mitochondria. The same process can be observed in nature: photosynthesis is an example most people understand. LLLT causes a similar biological response within cells, creating a regenerative effect that is especially useful for treating pain caused by injury, or illness impacting the nervous system.
Cold lasers are non-invasive. They emit no heat, sound, or vibration, though some people report a tingling sensation when I use it on them. Sometimes nothing appears to be different or happening. Hot lasers, which destroy tissue, can clearly be observed. It’s easy to understand why skeptics argue that cold lasers are ineffective.
I have used my cold laser extensively on myself, family and friends, all with positive results. While the animals I use it on cannot report to me with language, their improvement in movement speaks for itself.
