Pain was measured on an 11-point Likert numerical rating scale, ranging from 0=“No pain” to 10=“Pain as bad as you can imagine”.Participants were given diary at weeks 0, 5, 10, and 15. They started diary 7 days prior to their clinic visits at 0,4,9,14,19. Each day, recorded a number from 0 to 10. These numbers were averaged by the number of days so the total range of scores is still from 0 to 10.

The BPI interference scale measured level of interference with the following seven items:

General activity
Mood
Walking ability
Normal work
Relations with other people
Sleep
Enjoyment of life

Interference scales range from 0=’Does not interfere’ to 10=’Completely interferes’. The overall BPI score is the mean of seven items.

The CES-D is a 20-item self-report rating inventory measuring characteristic attitudes and symptoms of depression. Participants were asked to score each item:(0)Rarely,(1)Occasionally,(2)Sometimes,(3)Most of time.Some items are multiplied by -1 to change direction.

The overall CES-D score is simply the sum of 20 items. The highest possible total CES-D score is 48, and the lowest possible score is -12. The total CES-D score is considered missing if more than 4 items are not answered.
