Photobiomodulation Therapy (PBM) is also referred to as low level light laser therapy (LLLT), or Low-power laser therapy (LPLT). Not to be confused with the laser therapies that are used for types of surgery, other areas of medicine. In contrast, PBM lights have a red and near – infrared energy frequency which cannot be seen by the naked eyes however they are still able to affect our bodies and tissues on the cellular level in a beneficial way to promote healing.
The main differences between the red and near – infrared lights and laser therapies are that the laser therapies can penetrate much deeper through the layers of the skin to reach the underlying structures. Laser therapies can offer significant benefits to numerous issues but extensive training and great care needs to be had when using them to prevent any damage to healthy surrounding tissues.
The PBM lights are on a different wavelength, are much safer to use and do not pose any risk of damage to healthy or surrounding skin. Interest in the healing benefits of Photobiomodulation has grown over the years since it was first discovered my mistake in 1967 by Endre Mester while he was trying to repeat an experiment (https:// pubmed.ncbi.non.nih.gov).
Numerous scientific studies have been carried out and the list of benefits of PBM continues to grow. Explaining the beneficial effects of PBM can be complex and quite scientific. It all comes down to changes at the cellular level. Studies have found that cells within any body due to various environmental, physiological triggers undergo a form of stress called Oxidative stress. It is this oxidative stress which is found to be the primary cause of most inflammatory or degenerative conditions and diseases. However when red and near-infrared light is placed on an area, changes occur at the cellular level which helps promote tissue repair, reduces inflammation and induces analgesia.
With this understanding Photobiomodulation therapy has for a long time been used in areas of sport rehab, muscular / skeletal injuries and even with training. Prior lights were used to treat Seasonal affective Disorder. Within the Equine industry, PBM has cut the time of complex wounds considerably as well as promote recovery from muscular injuries. In human medicine PBM is used to support treating complex leg ulcers and wounds, also even found to be effective with managing myofascial pain.
Amazon sells many different style and shapes of ‘PBM’ lights, but be aware that many do not have the correct wavelength for the benefit to be achieved.
