Forskning i LLLT / Photobiomodulation

Uafhængig forskning har vist, at lys med korrekt bølgelængde kan forsyne cellerne med den nødvendige energi til at aktivere og hurtigt stimulere kroppens egen evne til at hele, samt øge cirkulationen. Fordelene ved LED-lysterapi, også kaldet LED-LLLT (Low Level Light Therapy, LLLT) eller photobiomodulation (PBM), er dokumenteret i videnskabelige studier og en række kliniske studier/cases, blandt andet gennem NASA og DARPA i USA.

IS LIGHT-EMITTING DIODE PHOTOTHERAPY (LED-LLLT) REALLY EFFECTIVE?

"In conclusion, based on the published data and the authors’ own experience, LED phototherapy is proving to have more and more viable applications in many fields of medicine. However, it must always be remembered that not any old LED will do. In order to be effective, LED phototherapy must satisfy the following 3 criteria.

The LED system being used must have first of all, and most importantly, the correct wavelength for the target cells or chromophores. At present, the published literature strongly suggests 830 nm for all aspects of wound healing, pain, anti-inflammatory treatment and skin rejuvenation, with a combination of 415 nm and 633 nm for light-only treatment of active inflammatory acne vulgaris. If the wavelength is incorrect, optimum absorption will not occur and as the first law of photobiology states, the Grotthus-Draper law, without absorption there can be no reaction.

Secondly, the photon intensity, i.e., spectral irradiance or power density (W/cm²), must be adequate, or once again absorption of the photons will not be sufficient to achieve the desired result. If the intensity is too high, however, the photon energy will be transformed to excessive heat in the target tissue, and that is undesirable.

Finally, the dose or fluence must also be adequate (J/cm²), but if the power density is too low, then prolonging the irradiation time to achieve the ideal energy density or dose will most likely not give an adequate final result, because the Bunsen-Roscoe law of reciprocity, the 2nd law of photobiology, does not hold true for low incident power densities.

Provided these three criteria are met, LED phototherapy does indeed work, and has many useful aspects in clinical practice for practitioners in many surgical specialties. As an exciting extension of the monotherapy approach with LED-LLLT, and even more importantly, the combination of appropriate LED phototherapy as an adjunct to many other surgical or nonsurgical approaches where the architecture of the patient’s skin has been altered will almost certainly provide the clinician with even better results with less patient down-time, in a shorter healing period, and with excellent prophylaxis against obtrusive scar formation."
