Results of treatment of chronic low-back pain at the Portland Pain Center.

We have evaluated 100 consecutive patients with low-back pain admitted to the Portland Pain Center. The average patient had been disabled for about 6 years, and had had an average of two 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 provides a multidisciplinary approach to the treatment of chronic low-back pain. Significant increases in functional capacity are demonstrated.
