The authors have used 780 nm, 20 mW, 0.04 cm2, 10 seconds, 0.2 J per point, 1.8 J per session. This is a very low energy. Energy (J) and dose (J/cm2) both have to be within the therapeutic window. By using a thin probe, a high dose can easily be reached but the energy here is much too low in my opinion. The authors quote Kymplova (2003) as having success with these parameters, but this is not correct. The multimode approach of Kymplova was as follows: The light sources were as follows: a laser of a wave length 670 nm, power 20 mW, with continuous alternations of frequencies 10 Hz, 25 Hz, and 50 Hz, a polarized light source of a 400-2,000 nm wavelength in an interval of power 20 mW and frequency 100 Hz and a monochromatic light source of a 660 nm wavelength and power 40 mW, with simultaneous application of a magnetic field at an induction 8 mT.
