The primary endpoint of the study is mean change in the Numerical Pain Rating Scale
for leg pain compared to intramuscular injection of placebo over four weeks.
Before initiation and after 3 months of treatment, the pain severity and psychological problems were assessed using Numerical pain rating scale
(NRS) and Depression, Anxiety and Stress Scale (DASS) respectively by the psychologist.
Pain was reported to fluctuate between 5-8/10 on a numerical pain rating scale

Clinical importance of changes in chronic pain intensity measured on an 11-point numerical pain rating scale
Clinical importance of changes in chronic pain intensity measured on an 11point numerical pain rating scale
15) This is a change of 8-9 levels on the Numerical Pain Rating Scale
(NPRS), which exceeds the MCID for patients with chronic pain.
Common one-dimensional pain rating scales are visual analogue scale, numerical pain rating scale
and verbal pain scale (LaBel, 2006; Green et al.
The patient described his elbow pain as a dull ache with the pain rated 5/10 on a numerical pain rating scale
Pain endpoints were assessed using an 11-point numerical pain rating scale
Visual analogue scale utilizes 5% (15/309), verbal pain scale 22% (69/309), and numerical pain rating scale
16% (48/309) of respondents (Figure 1).
In response to the increasing number of region-specific or condition-specific outcome measurement tools to choose from, this pilot study looked at the feasibility of using two easy to administer, patient-specific outcome measures: the Patient-Specific Functional Scale (PSFS) and the Numerical Pain Rating Scale
