SECONDARY outcome
Timeframe: 4 weeksNumber of Patients whose Patient global impression of change (PGIC) moderately or much improved- The PGIC is a 7 point scale that requires the clinician to assess how much the patient's pain has improved or worsened relative to a baseline state at the beginning of the intervention. and rated as: No change (or condition has gotten worse) (1) Almost the same, hardly any change at all (2) A little better, but no noticeable change (3) Somewhat better, but the change has not made any real difference (4) Moderately better, and a slight but noticeable change (5) Better and a definite improvement that has made a real and worthwhile difference (6) A great deal better and a considerable improvement that has made all the difference (7)improved This outcome is number of patients who chose a 6 or above on the PGIC 6 weeks after treatment.
