Primary Outcome Measures:
  • SPID-12 [ Time Frame: 12 hours ]

    The primary outcome measure is the summed pain intensity difference over the 12-hour study period (SPID-12). A pain intensity score ranging from 0 (no pain) to 10 (worst possible pain) is obtained at baseline and throughout the 12 hour study period. The SPID-12 is calculated by summing the difference between baseline pain score and pain score at each assessment time point.

    The SPID-12 ranges from -120 (indicative of an increase in pain) to 120 (indicative of a decrease in pain). A higher SPID-12 score is better.
