One hundred consecutive patients with low-back pain admitted to the Portland Pain Center were evaluated. The average patient was disabled for about 6 yr and had an average of 2 surgical attempts to improve his symptoms. Most of the patients considered had open claims with their workmen''s compensation carriers. Significant gains were demonstrated in drug reduction, general well behavior and increased range of motion and exercise tolerance. The Pain Center setting provided a multidisciplinary approach to the treatment of chronic low-back pain. Significant increases in functional capacity were demonstrated.
