Abstract
Oxygen Ozone therapy is one of the most spread methods for the care of back pain. The purpose of this observational retrospective study is to compare results of three treatment groups of patients suffering from Chronic Back Pain (CBP) associated with disc herniation: intramuscular Oxygen-Ozone infiltrations (O2O3), Global Postural Re-education (GPR) and the combination of both treatments. Statistical Analysis revealed that O2O3 therapy combined with GPR was more effective than GPR alone.
