Effectiveness and cost-effectiveness of chiropractic and physiotherapy for chronic low back pain: a multicenter RCT in Sweden.
Filip Gedin et al. (2025) · BMC musculoskeletal disorders
This Swedish trial asked whether a chiropractor, a physiotherapist, or advice to stay active works best for low back pain lasting months — and the honest answer is that it could not tell the three apart. Eighty-eight people at ten primary care clinics around Stockholm were randomly assigned to one of four things: advice only, physiotherapy, chiropractic care, or both together. Six months later, everyone was better. Disability scores dropped in every group — most in the chiropractic group, least in the physiotherapy group — but the gaps between groups were well within what chance alone would produce. Pain scores and quality of life told the same story: improvement everywhere, no clear winner. Where the groups did differ was cost. The advice-only group ended up costing the health system about three times more than the others — around SEK 11,000 per person versus roughly SEK 3,000 — mostly because those patients went on to see doctors more, and one of them had spine surgery. Getting hands-on treatment early appeared to head off more expensive care later, though with numbers this small a single surgery moves the whole average. Combining chiropractic care with physiotherapy came out best on the economics: slightly more quality-adjusted life years for slightly less money. But "slightly" is doing a lot of work — the difference across all four groups was eight thousandths of a QALY, which is roughly three days of perfect health. The researchers are unusually candid about the limits. They wanted far more participants than they got, nearly half the people dropped out before six months, and the four groups were not well matched at the start. They present this as a lesson for whoever runs the definitive trial next, not as a result to act on. What it does support, gently: for chronic low back pain, staying active matters, and both chiropractic care and physiotherapy are reasonable, comparably effective options — with some signal that getting treatment rather than advice alone may save money downstream.
