Sponsor's own description

This study investigates the effect of two physiotherapy models in the treatment of chronic nonspecific low back pain. Participants will be divided into three groups, two experimental and one control. In both experimental groups, the participants will be included in the intensive program of Therapy Exercises, under the supervision and guidance of the physiotherapist, and the group will differ in implemented behavioral therapy (which he will implement by a physiotherapist). In the control group, subjects will receive the usual treatment. The Back School will be applied in all groups.
