Electromyographic analysis of the results given by lumbar discal herniation treatment with intradiscal oxygen-ozone gas mixture injection.

Among patients treated by intradiscal oxygen-ozone administration, in the period from January to June 18, because of disco radicular conflict, we randomly selected a group of 200 cases for this study. The classical instrument for studying nerve functioning alteration is EMGraphy. Repeated EMGraphic control during the treatment gives a valid parameter to quantify nerve root dysfunction: this is objective, repeatable and is precise data. The evolution of EMGraphic picture does not always correspond to the clinical situation. In several cases the normalization of the last radicular conflict will coexist with residual signs of EMGraphic dysfunction.
