What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Efficacy of treatment in back pain relief based on Visual Analog Scale (VAS).
Time Frame: 4 days

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;
4 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Safety will be evaluated by the adverse events occurrences
Time Frame: day 4
Adverse events will be collected and followed in order to evaluate safety and tolerability
day 4
