Measure Description
Time Frame
Patient Global Impression of Improvement (PGI-I) Scale at One Year Endpoint.

baseline, 1 year
Brief Pain Inventory (BPI) Severity Scores at One Year Endpoint
Time Frame: 1 year
A self-reported scale that measures the severity of pain. The severity scores range from 0 (no pain) to 10 (pain as severe as you can imagine). There are 4 questions assessing worst pain, least pain, and average pain in the past 24 hours, and the pain right now.

Brief Pain Inventory (BPI) Interference Scores at One Year Endpoint
Time Frame: 1 year
Self-reported scale measures interference of pain on function in past 24 hours for general activity, mood, walking ability, normal work, relations with other people, sleep, enjoyment of life. Scores range from 0 (does not interfere) to 10 (completely interferes). Average interference = self-reported scale measures interference of pain on average of 7 questions assessing interference of pain for general activity, mood, walking ability, normal work, relations with other people, sleep, enjoyment of life. Average interference scores range from 0 (does not interfere) to 10 (completely interferes).

Beck Depression Inventory-II (BDI-II) Total Score at One Year Endpoint
Time Frame: 1 year
A 21-item, participant-completed questionnaire to assess characteristics of depression. Each of the 21 items corresponding to a symptom of depression is summed to give a single score. There is a 4-point scale for each item ranging from 0 to 3. Total score of 0-13 is considered minimal range, 14-19 is mild, 20-28 is moderate, and 29-63 is severe.
