A Feasibility Study of a Multidisciplinary Treatment for Patients with Chronic Low Back Pain: PAINDOC Study.

The present feasibility study aims to evaluate the feasibility and adequacy of a multidisciplinary treatment program as a therapeutic option for patients with chronic low back pain referred to the pain unit of the Hospital Clinic of Barcelona. Secondarily, the present study will also evaluate the effect on pain-related outcomes to estimate the number of needed participants for a full trial.

The main questions it aims to answer are:

* Is the proposed multidisciplinary treatment feasible and adequate for chronic low back pain patients?
* Is the proposed multidisciplinary treatment effective in improving pain-related outcomes?

Participants will receive either usual care (pharmacological control) or eight multidisciplinary sessions within two months, composed of therapeutic patient education, mindfulness relaxation, cognitive-behavioural therapy and therapeutic exercise. Besides, participants will be assessed using written questionnaires before and after treatment and two months after treatment.

Researchers will assess the feasibility of the multidisciplinary treatment group and will compare both groups to see if there is any difference in several pain-related outcomes.

Despite improving pharmacological and surgical medical treatment options, long-lasting low back pain is the most frequent pain disorder and a leading cause of disability. Over the past decades, clinicians have acknowledged that a broader view of disease and disability is needed in chronic conditions treatment. Therefore, biological, psychological and social factors must be addressed to improve such conditions.

The present study aims to evaluate the viability and adequacy of a multidisciplinary treatment program (PAINDOC Program) as a therapeutic option for patients with chronic low back pain referred to the pain unit of the Hospital Clínic of Barcelona. The secondary objectives are to evaluate the effect of the PAINDOC Program on the reduction of pain intensity, the improvement of pain-related disability, the improvement of quality of life, and the reduction of pain catastrophizing.
