Fifty patients with chronic low-back pain were subjected to extensive medical, psychiatric, and psychosocial assessment by a comprehensive Low Back Pain Clinic. Most patients were found to have easily identifiable environment factors which influenced the persistence of the symptomatology. All patients were significantly functionally impaired, and whilst neurologic findings were uncovered in only 12 patients, most had restricted movement of the lumbar spine. The initiating cause of the low-back pain was usually from a minor injury or no injury at all. Thirty-two patients were given psychiatric diagnoses, but only one patient was thought to warrant psychiatric treatment. Whilst some were considered to be candidates for limited further conservative treatment, only two were subjected to further surgery (one fusion, one posterior facet rhizotomy). Only nine were admitted to an inpatient behavior modification program, and the results of this effort were modest. The major benefit was seen to be the definitive diagnosis, prognosis, and medical and social planning which was given to all 50 patients upon conclusion of the assessment. The assessment proved to be of benefit to the patient, the referring doctor, the team itself, as well as all other interested parties, such as his family, insurance company, and lawyer.
