For chronic back pain, only movement held up long term

Chronic low back pain with no identifiable structural cause — non-specific chronic low back pain — is one of the most common reasons people seek treatment, and the menu of conservative options is enormous: rest, massage, TENS machines, supports, injections, painkillers, back schools, antidepressants and exercise. Patients and clinicians alike need to know which of these actually work, and over what timescale. This review set out to evaluate the evidence for the conservative treatments listed in Germany's national care guidelines, asking a simple question: which therapies have demonstrated effectiveness, and which are being used despite the evidence?

The authors conducted a systematic literature review of randomised controlled studies, reviews and meta-analyses drawn from the Cochrane Library and Medline, covering publications from 2004 to 2015 in German and English. Their search identified 4657 publications, of which 85 met the criteria for inclusion. They focused on the conservative treatments for non-specific chronic low back pain listed in the NVL guidelines and graded each therapy's effectiveness against the available evidence, distinguishing between short-term relief and lasting benefit beyond 6 weeks.

The clearest result was negative: bed rest, TENS, massage, spine supports, back schools and antidepressants showed no evident effectiveness for chronic non-specific low back pain. A second group — injections, NSAID analgesics, thermotherapy and opioid analgesics — showed short-term effectiveness, but no long-term success beyond 6 weeks could be demonstrated for any of them. Only movement therapy, across the summed evidence of the included studies, showed a long-term effect at Evidence Level I. For treatment-resistant cases, the authors suggest multimodal therapy should be considered.

This review reinforced a shift that back-pain research had been signalling for years: passive treatments underperform, and active ones endure. The finding that rest and supports lack evidence directly contradicts the intuition many people still hold — that a painful back should be protected and immobilised. It also frames painkillers, heat and injections honestly: useful for getting through an acute phase, not a solution. Open questions remain about which forms of movement therapy work best, for whom, and how multimodal programmes should be structured, and the evidence reviewed here predates 2015, so newer trials sit on top of it.

If you deal with long-running, non-specific back pain, this review is a reason to be sceptical of purely passive fixes — the pooled evidence found nothing lasting from rest, massage, TENS or supports, and only temporary relief from painkillers, heat and injections. The one approach with Evidence Level I support for long-term benefit was movement-based therapy. That is information about where the evidence points, not a prescription; anyone with persistent or worsening back pain is in territory where a proper clinical assessment matters.
