class iv therapeutic lasers are not only safe they can deliver an effective therapeutic dosage much deeper into the body and also effectively treat a large volume of tissue in the patient we know that when photons of light are absorbed in the body the overall effects are to increase blood circulation to increase the levels of tissue oxygenation and also to increase metabolic activity in cells with sumus medical lasers we use a blend of red and infrared wavelengths the protocols in the sumus medical lasers are preset lower power for superficial conditions such as epicondylitis higher power for deeper conditions such as lumbar disc disease we use combinations of continuous wave and various pulse frequencies we know that photons of light can penetrate into the body and have three main effects one of those is intracellular and that is the absorption by the cytochrome oxidase enzyme resulting in more energy production that we always hear about another is on the cell membrane absorption of photons by the cell membranes helps encourage proper exchange of ions across the cell membrane and the third is in the extracellular tissues to help with cell communication from one to the other the physiological effects of laser therapy are increased circulation reduced inflammation reduced pain and enhanced tissue healing
