Regarding laser therapy – I have a TheraLase 2000 and a Light Cure laser in my office. I don’t know any other Doctor who has this combo. To create ATP to heal tissues, you need to trigger the protein pump.
The work on the Arndt-Schulz law was done only on open wounds (Turner, Laser Phoyotherapy Clinical Practice and Scientific Background 2014). “Inhibition” is cited by some laser manufacturers as the reason why higher energy or certain wavelength lasers should not be used. The specific narrow finding has been extrapolated to all conditions that lasers treat. Low power density is recommended for open wounds because layers of the skin are missing. Typically, the layers of the dermis and epidermis absorb about 66 percent of laser energy.
Tiina Karu, PhD (Ten Lectures On Basic Science of Laser Phototherapy book) disproved the notion that once the point of inhibition is reached, more energy density (does) is harmful. She found at certain levels of dose that there was inhibition, but as the dose is increased the inhibition goes away and cells thrive more. Her findings are that the Arndt-Schultz law needed to be updated because there were a number of peaks and valleys.
That is way I have two lasers – ‘the ability to go low and go high dose’. It all depends on the patient I am with.
