[Exposure therapy for chronic back pain].

Exposure therapy is an economical and promising psychological method for the treatment of chronic back pain, although little research has been done and its evidence needs further clarification. Exposure therapy has so far been little used in practice, which is partly due to the few published studies on this topic and partly to the uncertainty of the practitioners as to whether exposure therapy can be carried out without risk. Exposure therapy can be classified as a "tailored treatment" approach, in which patients with certain profiles (here: increased fear of movement) receive specific treatments. In this review article, the theoretical principles of exposure therapy are presented. Subsequently, possibilities for the identification of those patients suitable for exposure treatment are explained. The practical procedure is presented using a case study. The four randomized controlled trials available to date are described in detail and discussed.
