Title: Behavioral Interventions for Low Back Pain
Brief Summary: Low back pain is a very common problem and the most common cause of job-related disability. While some occurrences of low back pain disappear within a couple of days, other occurrences take much longer to resolve or lead to more serious conditions. The purpose of this study is to determine the effectiveness of two behavioral types of therapy in reducing future disability in people who are receiving physical therapy for low back pain and tend to fear and avoid pain.
