Roundup of the decade – a big thank you note

Wow, what a decade it has been for LLLT. Credibility is critical for acceptance by reimbursement and regulatory authorities as well as doctors and therapists. In the last ten years over 1,000 papers have been published that build on the work of the early pioneers. Highlights of this decade include: FDA clearance, publication in high impact factor journals such as Nature, Pain, PNAS, Spine, Muscle and Nerve, Stroke, Blood and, of course, The Lancet. Output from world renowned institutions including Harvard Medical School, NASA and the US Navy add further reassurance.

The next decade of LLLT – the barriers to mainstream adoption

Because LLLT modulates cellular oxidation and energy production it could potentially affect  a wide range of diseases, injuries or other dysfunctions in the body.

By the end of the next decade, it is possible  LLLT may be used in almost every department of every hospital (and every medicine cabinet of every home).

Given the amount of good quality research published over the last decade, why isn’t it part of mainstream medicine already?

LOW LEVEL LASER / PHOTOBIOMODULATION DOSIMETRY. WHAT ARE THE THRESHOLDS AND WHAT ARE THE LIMITS?

James D Carroll FRSM, AMInstP, THOR Photomedicine Ltd, United Kingdom

Photobiomodulation includes biostimulation and bioinhibition. In vitro, in vivo and clinical studies have established that there are radiant intensities and energy thresholds below which no significant cellular stimulation or clinical effects are achieved.  Conversely there are radiant intensities and total fluence thresholds above which cellular stimulation decreases from its peak effect and inhibition is achieved. Many dose-ranging studies have been published using a variety of laboratory and clinical models and most suggest that cellular stimulation is achieved at radiant intensities in the range of 5 – 50mW/cm2 (at the target tissue ) and that exceeding these levels can inhibit cellular function.

So what is the role of the higher intensity laser products that appear to be popular with some clinicians and their patients ?
