The aim of the present study was to quantitatively analyze the response of patients with chronic low back pain to treatment at the Back School at the IMREA-HCFMUSP. The following scales were used to measure the therapeutic response: the Oswestry Low Back Pain Disability Questionnaire, a Visual Analog Scale (VAS), and a corporal diagram of the pain. The sample was composed of 43 patients with chronic low back pain evaluated, treated, and referred to by the Back School program. The results showed significant improvement among those who completed the program in all three scales applied. Since the period of study was only two months, the results do not support any claim that the Back School is also this effective on long-term treatment of chronic low back pain. Further qualitative and quantitative studies must be carried out in order to support the development of specialized multi-professional teams, who will carry out alterations and improvements in therapeutic resources to the management of chronic low back pain.
