What is the study measuring?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain score evaluated by patient-rated visual analog scale: the levels of spontaneous pain is indicated by the patient by means of a 10 centimetre non-graduated scale, in which the patient could estimate the intensity of pain |  | During patient visits: day 1, day 3 and day 5 to 10 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mobility Hand-to-floor distance is evaluated by a simple graduated bar (0 value at floor). |  | During patient visits: day 1, day 3 and day 5 to 10 | 
| Disability Questionnaire (Roland Morris) |  | During patient visits: day 1, day 3 and day 5 to 10 | 
| Physician rated Clinical Global Impression Scale |  | During patient visits: day 1, day 3 and day 5 to 10 |
