Outcome Measures

Primary Outcomes (1)

  • Visual Analog Scale (VAS) on Back Pain

    Visual Analog Scale (VAS) back pain scores were recorded once a day on a multi-day diary, where subjects rate the pain by making a vertical slash mark through the 0-10cm line that best describes their pain during the last 24 hours, with 0 = No pain and 10 = Worst pain imaginable. The higher VAS back pain score represented worse back pain. The average VAS back pain scores from the last three days of diary prior to the follow-up visits were used for analysis.
