Select the number that best describes your average low back pain during the past week. 0 = No pain; 10 = Worst possible pain (recoded so that 10 = 5, 7–9 = 4, 4–6 = 3, 1–3 = 2, and 0 = 1; based on Sheehan Disability Scale and the Flushing Questionnaire) (6 weeks-baseline).
Note: F (6, 627) = 58.39, P < .0001. Cells that share a superscript do not differ significantly from one another.
