Medi- cal costs were measured in euros (EUR) and effec- tiveness was measured using Graded Chronic Pain Status (GCPS). Design: A controlled multicentre study (39 sites) with a 6-month intervention phase and follow-up at 6, 12 and 18 months. Subjects: The study included 1,829 participants in an intervention group and 495 individuals in a control group. Methods: The multimodal back exercise programme comprises 36 exercise sessions for optimizing the spine stabilizing muscles and everyday motor func­ tions. The patients were given a home training pro- gramme at the end of the intervention programme. Results: The back exercise programme resulted in a significant reduction, of 0.4, in back pain grade on the GCPS after 2 years, compared with standard treat­ment, and reduced medical costs by 763 EUR. The exercise programme was therapeutically effecti- ve for GCPS back pain grades 1–4 and produced cost savings in the case of grade 4 GCPS. Conclusion: The multimodal back exercise program- me was therapeutically effective for back pain (gra- des 1–2) and pain-related functional impairment (grades 3–4). It resulted in reduced costs for chro- nic back pain causing high pain-induced functional impairment (grade 4). The therapeutic and econo- mic effects of the programme increase with the gra- de of back pain. Key words: cost-benefit analysis; back pain; exercise.

LAY ABSTRACT This study compared the cost-effectiveness of a back exercise programme for different levels of back pain with standard treatment. The back exercise programme resulted in a reduction in back pain after 2 years com- pared with standard treatment. Moreover, the exercise programme resulted in reduced medical costs. The back exercise programme was found to be therapeutically ef- fective and cost-efficient. The therapeutic and econo- mic effects of the programme increased with severity of back pain. With a monthly prevalence of 23% worldwide (2) and a lifetime prevalence in Western industrial nations exceeding 70% (3, 4), back pain incurs high direct and indirect medical costs (5–7). In 80–90% of cases, back pain progresses favour­ ably, and patients return to work within 6–8 weeks. Sixty percent of patients are pain free within the first 4 weeks. The 8–10% of patients who develop chronic back pain significantly increase the direct and indi- rect costs (8, 9). The high socioeconomic importance of back pain contrasts noticeably with a lack of knowledge about the cost-effectiveness of different interventions, and it does so against a background of tightening healthcare resources. Exercise is one of the interventions viewed as effective against chronic back pain. However, what we know about it is very general in nature: no one type of exercise is regarded as superior (10). Despite years of research, we do not yet know which exercise to favour, with how many exercise sessions, and with what intensity. Specifically, we do not know if the therapeutic and economic effects also vary with the severity of the back problem (11). AOK Baden-Wuerttemberg, a major German sta- tutory health insurer, since 2005 has provided insured individuals who experience back pain with a multimo- dal (strength/mobility and ergonomic) back exercise programme. Approximately 30,000 patients enrol in this programme annually. The goal of the present study was to determine how the benefit from this exercise This is an open access article under the CC BY-NC license. www.medicaljournals.se/jrm Journal Compilation © 2019 Foundation of Rehabilitation Information.
