To achieve desired therapeutic dosages it is more important to consider longer treatment times than higher power levels, contrary to claims made by other manufacturers. Decades of research prove that therapeutic laser power levels over 10W actually cause damage to the treatment area, commonly known as photobioinhibition. Typical maximum therapeutic dosage levels per treatment for laser therapy are established at 10 Joules/cm2, which is achieved at a power setting of 5W and duration of 3 minutes; larger dosages are considered counterproductive, whether they are achieved by higher power settings on longer treatment times. Any claims made to the contrary are false and misleading.
