Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Average Pain Intensities Measured From the Pre-Treatment Walk (Baseline) at 3 Post-Treatment Walks
Time Frame: All pain intensities measured from the pre-treatment walk and 3 post-treatment walks (within 3 and half hours post dose, 15 minutes each walk separated by a 45-minute rest interval)

Pain intensities(PIs) were measured at pre-dose and 3 post-dose walks (15 Minutes Each Separated by a 45-Minute Rest Interval) on an 11 point scale(0=no pain; 10=worst pain) and averaged for each walk.

Change from baseline was average of post-dose PIs minus average of pre-dose PI.

All pain intensities measured from the pre-treatment walk and 3 post-treatment walks (within 3 and half hours post dose, 15 minutes each walk separated by a 45-minute rest interval)
