Abstract

Background: Low back pain is one of the leading causes of disability worldwide. Exercise therapy is widely recommended to treat persistent non-specific low back pain. While evidence suggests exercise is, on average, moderately effective, there remains uncertainty about which individuals might benefit the most from exercise. Methods: In parallel with a Cochrane review update, we requested individual participant data (IPD) from high-quality randomised clinical trials of adults with our two primary outcomes of interest, pain and functional limitations, and calculated global recovery. We compiled a master data set including baseline participant characteristics, exercise and comparison characteristics, and outcomes at short-term, moderate-term and long-term follow-up. We conducted descriptive analyses and one-stage IPD meta-analysis using multilevel mixed-effects regression of the overall treatment effect and prespecified potential treatment effect modifiers. Results: We received IPD for 27 trials (3514 participants). For studies included in this analysis, compared with no treatment/usual care, exercise therapy on average reduced pain (mean effect/100 (95% CI) −10.7 (−14.1 to –7.4)), a result compatible with a clinically important 20% smallest worthwhile effect. Exercise therapy reduced functional limitations with a clinically important 23% improvement (mean effect/100 (95% CI) −10.2 (−13.2 to –7.3)) at short-term follow-up. Not having heavy physical demands at work and medication use for low back pain were potential treatment effect modifiers—these were associated with superior exercise outcomes relative to non-exercise comparisons. Lower body mass index was also associated with better outcomes in exercise compared with no treatment/usual care. This study was limited by inconsistent availability and measurement of participant characteristics. Conclusions: This study provides potentially useful information to help treat patients and design future studies of exercise interventions that are better matched to specific subgroups.

  • Prior reviews have confirmed that exercise prevents non-specific back pain in the lumbar and cervical regions.

    “Different reviews have confirmed the benefits of exercise on the prevention of NBP in the lumbar [11,12,13,14] and cervical regions [15,17,19,20].”

    From Prevention of non-specific back pain through exercise and education: A systematic review and meta-analysis (2024) · cites this paper as [13]

    The Introduction reports that exercise therapy decreases pain and improves function in adults with persistent low back pain, and the Pain and functional limitation outcomes section reports benefits over usual care or no treatment. These are treatment findings, not evidence that exercise prevents low back pain. The cervical-region claim has separate citations in the citing sentence and is not attributed to this paper. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Several systematic reviews have examined exercise benefits for low back pain prevention in terms of pain reduction, disability, quality of life, and kinesiophobia.

    “In fact, there are several systematic reviews that have examined the benefits of exercise for the prevention of low back pain with regard to pain reduction, improvement of disability, quality of life and kinesiophobia [11,12,13,14].”

    From Prevention of non-specific back pain through exercise and education: A systematic review and meta-analysis (2024) · cites this paper as [13]

    The Introduction (page unavailable) describes a Cochrane review and says exercise therapy decreases pain and improves function in adults with persistent low back pain; the References also list other exercise-therapy reviews. The paper addresses treatment of existing pain, not prevention, and the cited review findings do not cover quality of life or kinesiophobia. (LLM, conf=0.89)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
