Back schools in Brazil: a review of the intervention methodology, assessment tools, and results.

The Back School is characterized as an educational program aimed at individuals who have chronic pain in spine. In Brazil, a growing number of research studies on the effects of such programs have been observed in the last decades. Thus, the purpose of this systematic review was to identify studies on Back Schools carried out in Brazil with a population of adults and elderlies, and to compare their intervention methodologies, data collection tools, and results. A search for scientific articles and Master's and doctoral theses in several databases was conducted. The keywords used in that search were Postural Program; Postural School; Back School; Back Care Education; Back Education, as well as the respective terms in Portuguese. Eighteen studies were found, being fourteen quantitative and four qualitative studies.The studies showed many differences between them, in both the interventions proposed and the methodological design. However, the use of similar tools for assessing pain intensity, functional capacity, and quality of life between the quantitative studies allowed a partial comparison of the efficacy of those programs.The studies included in this systematic review demonstrated, in general, the immediate efficacy in reducing pain and improving functional capacity and quality of life after the Back School. Results, however, are still conflicting regarding the efficacy in the medium and long terms. Thus, it becomes necessary to conduct further studies that include follow-up assessments in the medium and long terms in order to obtain more accurate conclusions about the efficacy of Back Schools.
