This paper examines why one-fourth to two-thirds of all chronic low back pain patients who are treated at multidisciplinary clinics eventually regress to pretreatment levels. A literature review was conducted and the following variables were found to significantly affect whether patients maintain treatment gains: employment status, compensation, social reinforcement of pain behaviors, and maintenance of exercise regimens.
