Outcome Measures

Primary Outcomes (2)

  • Change in Pain Intensity for Overall Pain From Pre-treatment Baseline

    The Visual Analog Scale (VAS) is self-administered instrument assessing average pain intensity. Subjects rated their pain on a horizontal line, 10 cm in length, anchored by word descriptors on each end (no pain to worst imaginable pain). A higher score indicates a higher pain level. The values range from 0 (minimum pain) to 10 (maximum pain).

    Baseline, 3, 6 and 12 Months

  • Percentage of Subjects With at Least 50% Pain Reduction

    Percent of subjects with at least a 50% reduction. The Visual Analog Scale (VAS) is self-administered instrument assessing average pain intensity. Subjects rated their pain on a horizontal line, 10 cm in length, anchored by word descriptors on each end (no pain to worst imaginable pain). A higher score indicates a higher pain level. The values range from 0 (minimum) to 10 (maximum).
