Primary

Measure	Time frame
Measured at baseline, three months and eight months: 1. Socio-sanitary costs (direct and indirects costs) 2. Functional and psychological disability in nonspecific low back pain (using Roland-Morris Questionnaire, the Oswestry Disability Index and the Start Back Tool [SBST]) 3.
