Ozone therapy on pain and functionality of individuals with low back pain

INTERVENTION: The experimental design of this research will be constituted by the initial physiotherapeutic evaluation with collection of patient data, history and also radiological evaluation, if possible, to exclude possible fractures. After entering the research, the volunteers will be submitted to the following evaluations: pain (numerical pain scale, functionality (Quebec and Rolland Morris Lumbar Disability Questionnaire), quality of life (Oswestry Disability Index), trunk flexion and extension mobility test, emotional state (Numeric Anxiety Scale and Beck Depression Inventory) and analysis of the perception of the global effect of the treatment.It should be noted that these assessments will be carried out before and after the treatments. Participants will undergo interventions twice a week over a period of 6 weeks, totaling 12 sessions. Control Group: volunteers will be submitted to a standard program of conventional rehabilitation that will happen through the use of exercises that include strengthening, stretching, mobilization, coordination and stabilization of the abdominal, lumbar, pelvic and lower limb muscles; Ozone Group: volunteers will be submitted to the exercise protocol and the application of ozone therapy with an injector tip for application in 10 points in the lumbar region, using the subcutaneous technique.
