Comprehensive multidisciplinary treatment of chronic pain: a follow-up study of treated and non-treated groups.

There are relatively few outcome studies of multidisciplinary chronic pain programs which have utilized no-treatment comparison groups. The present study compared a group of chronic pain patients (N = 42) treated in a comprehensive multidisciplinary pain program with a group of patients (N = 15) who were evaluated but not treated. Comparisons were made at evaluation and at a follow-up period averaging 11 months later.
