Study & Design

Study Type
INTERVENTIONAL

FACTORIAL
Primary Outcome Measures
NameTimeMethod
Pain intensityFour weeks after randomization

Pain intensity will be evaluated by numerical rating scale (0-10).

Secondary Outcome Measures
NameTimeMethod
Quality of pain4 weeks, 3 and 6 months after randomization.

The Short form of the McGill pain questionnaire (SF-MPQ) consists of 15 representative words from the sensory and affective categories of the standard long form. The 6 point intensity scale and a VAS are included to provide indices of overall pain intensity.

Disability4 weeks, 3 and 6 months after randomization.

The Roland Morris disability questionnaire (RMDQ) is composed of 24 yes or no questions designed to assess disability related to back pain.

Pain intensity3 and 6 months after randomization

Pain intensity will be evaluated by numerical rating scale (0-10)

Global perceived effect (GPE)4 weeks, 3 and 6 months after randomization.

Global perceived effect is an 11 point scale that ranges from 5 (vastly worse) through 0 (no change) to 5 (completely recovered). For all measures of global perceived effect (at baseline and all follow-ups), participants were asked compared to when this episode first started, how would you describe your back these days. A higher score indicates higher recovery from the condition.
