[Intensive multidisciplinary treatment of back pain--2 controlled prospective studies].

The aim of this study was to evaluate an intensive, multidisciplinary functional restoration program for people with chronic low back pain. The program was compared to a non-treated control group in project A, and to less intensive treatment programs in project B. Both projects were randomized and observer blinded. Two hundred and thirty-eight patients were included, 106 entering project A and 132 project B. All had had chronic low back disability of at least six months duration, with an average of one year's sick leave due to low back pain over the last three years. Their average age was 41 years. The results at follow-up (conducted four months after treatment, follow-up rate 90% in project A and 86% in project B) showed that 67% of the treated patients in project A were able to work compared to 28% in the control group. In project B, 75% of the patients treated in the functional restoration program were able to work, the corresponding numbers from the less intensive programs being 48% and 40%. Numbers of days of sick leave, contacts to the health-care system and pain- and disability-scores were significantly lower for the patients treated in the functional restoration program compared to the other groups in both projects. Functional restoration is more expensive to carry out, but the long-term benefits in form of reductions in pensions, sick leave and contacts to the health-care system, not to mention reduced pain for the patients, seems to justify this expenditure.
