Methods
Oswestry Disability
We conducted an open-label, randomized, controlled, parallel-group pilot clinical trial with CNSLBP patients irresponsive to conservative treatment. Patients between 18 and 67 years of age were randomly assigned (1:1) to either Standard-of-Care + MGVA (experimental group) or Standard-of-Care alone (control group). MGVA consisted of integrated sessions for physical rehabilitation/physiotherapy, psychology, and social work treatments. The control group received standard clinical practice treatment.The feasibility was assessed by the number of study procedures completed to at least 80% as planned. The impact on clinical practice was evaluated by the number of patients who changed their status from "candidate" to "non-candidate" to low back surgery as the treatment of choice for CNSLBP. The SF–36, Oswestry Disability Index, and TMMS–24 questionnaires were used. We performed a whole population-based descriptive analysis.
