Bottom line
Across 15 randomized trials, pain neuroscience education added to exercise or physiotherapy was associated with reduced pain, disability, kinesiophobia, and catastrophizing in chronic low back pain, but small, varied trials and possible publication bias mean the evidence is promising rather than conclusive.

Study Summary
This systematic review and meta-analysis pooled 15 randomized controlled trials (810 patients with chronic low back pain) to assess whether pain neuroscience education (PNE) — an approach that helps patients reconceptualize how pain works — reduces pain, disability, kinesiophobia (fear of movement), and catastrophizing. PNE, usually combined with exercise or other physiotherapy, was associated with reductions in pain, disability, and kinesiophobia at the end of treatment and at 1 and 3 months of follow-up, and in catastrophizing at the end of treatment and 1 month. The authors rate the trials as good methodological quality on average (PEDro 6.8 ± 1.1) but caution that the small number and size of trials, heterogeneous protocols, and signs of publication bias in some analyses mean results should be interpreted carefully. They note longer-term (6–12 month) effects could not be assessed.
Key Findings
| Finding | Detail | Impact |
|---|---|---|
| PNE was associated with reduced pain intensity at all three time points | Pooled SMD = −0.65 (95% CI −1.1 to −0.2; p = 0.005) at end of intervention (k = 13); SMD = −1.05 (95% CI −1.56 to −0.53; p < 0.001) at 1 month; SMD = −1 (95% CI −1.5 to −0.5; p < 0.001) at 3 months. Pain was measured with NPRS, VAS, and McGill Pain Questionnaire. | High |
| PNE was associated with reduced disability through 3 months | SMD = −0.6 (95% CI −1.11 to −0.15; p = 0.009) at end of intervention (k = 10); SMD = −0.78 (95% CI −1.27 to −0.29; p = 0.002) at 1 month; SMD = −0.84 (95% CI −1.42 to −0.26; p = 0.004) at 3 months. Measured with the Roland Morris Disability Questionnaire and Oswestry Disability Index. | High |
| PNE was associated with large reductions in kinesiophobia (fear of movement) | SMD = −1.12 (95% CI −1.8 to −0.5; p < 0.001) at end of intervention (k = 6); SMD = −1.51 (95% CI −2.1 to −0.97; p < 0.001) at 1 month; SMD = −1.57 (95% CI −2.47 to −0.66; p = 0.001) at 3 months. Measured with the Tampa Scale of Kinesiophobia. | High |
| PNE was associated with reduced pain catastrophizing at the end of intervention and 1 month | SMD = −0.9 (95% CI −1.61 to −0.17; p = 0.016) at end of intervention (k = 5) and SMD = −1.36 (95% CI −2.34 to −0.37; p = 0.007) at 1 month (k = 3), measured with the Pain Catastrophizing Scale. No data were available to assess catastrophizing at 3 months. | Medium |
| Trials were of good average methodological quality but had recurring biases | Mean PEDro score was 6.8 ± 1.1; 13 of 15 RCTs (87%) were rated good and 2 (13%) moderate. Selection bias (5 RCTs), performance bias (nearly all RCTs, since participants/therapists could not be blinded), and detection bias (6 RCTs) were the main limitations. | Medium |
| Publication bias was suggested in some analyses and partly attenuated the effects | Trim-and-fill adjustment for kinesiophobia at end of intervention reduced the effect by 84% (adjusted SMD = −0.70) and for disability at 3 months by 90% (adjusted SMD = −0.44); a smaller 35% adjustment was noted for post-intervention pain. No publication bias was found for catastrophizing. | Medium |
Strengths
- Prospectively registered protocol (PROSPERO) and conducted following PRISMA 2020 and the Cochrane Handbook
- Largest and most up-to-date of the reviews on this topic to date, with 15 RCTs and 810 patients
- Separated short-term outcomes into distinct time points (end of intervention, 1 month, 3 months) rather than collapsing them
- Most pooled analyses showed low or null statistical heterogeneity (I² often 0%)
- Formally assessed publication bias (Egger test, trim-and-fill) and ran leave-one-out sensitivity analyses
- Excluded studies where other treatments could overshadow the effect of PNE
Limitations
- Low number of RCTs in several analyses and overall small total sample size, limiting generalizability and precision
- Chinese and Japanese databases were not searched
- Selection, performance, and detection biases were present in the included trials and could over- or under-estimate the true effect
- Publication bias was suggested in some analyses; trim-and-fill substantially lowered effect sizes for kinesiophobia (post-intervention) and disability (3 months)
- Heterogeneity in PNE protocols and comparators across the included studies makes findings harder to standardize
- Effects at 6 or 12 months could not be assessed because the included RCTs lacked that data
Key Takeaways for Patients
What This Means for You
Pain neuroscience education (PNE) teaches you how pain works in the nervous system, using metaphors and stories, to help you re-think and worry less about your pain.
In this review of 15 studies, adding PNE to exercise or physiotherapy was linked to less pain, less disability, less fear of movement, and less catastrophizing in people with long-term low back pain.
Benefits for pain, disability, and fear of movement appeared to last at least up to 3 months after treatment ended.
PNE is usually a complement to active treatment like exercise, not a replacement — the studies most often combined the two.
The researchers caution that the trials were small and varied, so results should be viewed as encouraging rather than definitive, and longer-term (6–12 month) effects are still unknown.
