Outcome Measures
Primary Outcomes (1)
Efficacy of treatment in back pain relief based on Visual Analog Scale (VAS).
The individual response rate to the relieve of pain is calculated by measuring VAS during the first and last visit. The response rate is calculated using the following formula: Response rate = (VASvi - VASvf) / VASvi Considering: * VASvi: VAS in the first visit; * VASvf: VAS at the last visit;

Secondary Outcomes (1)
Safety will be evaluated by the adverse events occurrences
