Bottom line
Pain neuroscience education shows a tendency to improve psychosocial outcomes (notably a small effect on kinesiophobia) in osteoarthritis patients, but benefits are small, inconsistent, and cannot yet be attributed to education alone — more research is needed.

Study Summary
This systematic review examined whether pain neuroscience education (PNE) — an educational approach that teaches patients about the biology and physiology of pain — improves pain and psychosocial outcomes in adults with osteoarthritis (OA), most of whom were knee OA patients facing or recovering from knee replacement surgery. After screening 12,573 records, only four studies met inclusion criteria, delivered across 1–6 sessions. The authors found a tendency toward improvement in groups receiving PNE, with a small effect favoring PNE for kinesiophobia (fear of movement), but effects on pain catastrophizing and pain intensity were small and inconsistent, and no clear benefit was seen for disability. A meta-analysis was not possible due to heterogeneity, and the authors caution that observed pain improvements may be partly attributable to medications rather than education alone.
Key Findings
| Finding | Detail | Impact |
|---|---|---|
| Only four studies qualified, and a meta-analysis was not possible | From 12,573 initial titles (202 unique records after de-duplication), just four articles met inclusion criteria. They used differing interventions and dosing (1–6 sessions; sessions ranging 30–60 minutes), so the heterogeneity and small number of studies prevented pooling the data into a meta-analysis. | High |
| Improvement favored PNE groups, but cannot be attributed to education alone | The review reported a tendency toward improvement in groups managed with PNE, but small effect sizes were observed for key variables such as pain catastrophizing and kinesiophobia. Pain reductions, particularly after surgery, may be mediated by medications (ranging from opioids to NSAIDs) rather than the educational intervention itself. | High |
| Small effect favoring PNE for kinesiophobia (fear of movement) | Significant changes in kinesiophobia were reported 3 months postoperatively in favor of the PNE group versus control in one study, and significant change versus baseline in a single-group study. In another comparison, both groups improved over time with no between-group difference. | Medium |
| Inconsistent effects on pain catastrophizing | One study found a significant result favoring the PNE group (p = 0.036). Another showed post-intervention improvement favoring PNE at 1 month, but the difference evened out by the 3-month follow-up. A single-group study found no significant change versus baseline. | Medium |
| No clear benefit for disability; pain intensity results were mixed | No significant between-group differences in disability were attributed to PNE, though WOMAC scores improved for both groups at 1 month before leveling off. For pain intensity, one study found a significant benefit for PNE added to conventional rehabilitation (at rest and while walking), while other comparisons found no significant between-group differences. | Medium |
| PNE appeared safe with reasonable adherence | No adverse events from the PNE intervention were reported in any study. Reported adherence levels were 84%, 63% at 1-year follow-up, 100%, and 81% across the included studies. | Low |

The review reported a tendency toward improvement in groups managed with PNE, but small effect sizes were observed for key variables such as pain catastrophizing and kinesiophobia. Pain reductions, particularly after surgery, may be mediated by medications (ranging from opioids to NSAIDs) rather than the educational intervention itself.
Significant changes in kinesiophobia were reported 3 months postoperatively in favor of the PNE group versus control in one study, and significant change versus baseline in a single-group study. In another comparison, both groups improved over time with no between-group difference.
One study found a significant result favoring the PNE group (p = 0.036). Another showed post-intervention improvement favoring PNE at 1 month, but the difference evened out by the 3-month follow-up. A single-group study found no significant change versus baseline.
No significant between-group differences in disability were attributed to PNE, though WOMAC scores improved for both groups at 1 month before leveling off. For pain intensity, one study found a significant benefit for PNE added to conventional rehabilitation (at rest and while walking), while other comparisons found no significant between-group differences.
No adverse events from the PNE intervention were reported in any study. Reported adherence levels were 84%, 63% at 1-year follow-up, 100%, and 81% across the included studies.
Strengths
- Pre-registered protocol (PROSPERO CRD42021222763) following Cochrane and PRISMA methodology
- Comprehensive multi-database search (MEDLINE, OVID, LILACS, Scopus, PEDro, OTseeker, Cochrane Library, EBSCO, Google Scholar) with no language or date restriction
- Independent, blinded study selection and data extraction with a third reviewer for disagreements
- Formal quality and certainty appraisal using MINORS, PEDro, and GRADE
- Honest, hedged interpretation that acknowledges medication as a potential confounder of pain results
Limitations
- Only four studies could be included, limiting the strength of any conclusions
- A meta-analysis was not possible due to heterogeneity in interventions and dosing
- Effect sizes for key variables (pain catastrophizing, kinesiophobia) were small
- Pain improvements may be confounded by pharmacological treatment (e.g., opioids, NSAIDs), especially post-surgery
- Small sample sizes and adherence variability across the included studies
- Stress level, one of the originally planned outcomes, was not addressed by any included study
- The protocol had to be broadened from clinical trials to also include observational studies due to lack of literature
- Population was narrow (largely knee OA / arthroplasty candidates), limiting generalizability to other OA joints
Key Takeaways for Patients
What This Means for You
- 01Pain neuroscience education (PNE) teaches you how pain works in your nervous system, with the goal of helping you understand your pain and develop better coping strategies.
- 02In osteoarthritis — mostly knee OA in patients facing or recovering from knee replacement — PNE showed a small benefit for fear of movement (kinesiophobia), but its effects on pain and catastrophizing were small and inconsistent.
- 03Improvements in pain after surgery may be due to medications rather than the education itself, so PNE should be viewed as a supportive part of care, not a standalone cure.
- 04PNE was delivered in just 1–6 short sessions, appeared safe with no reported adverse events, and may be a reasonable add-on to standard treatment such as exercise.
- 05The evidence is still limited (only four studies), so more research is needed before strong recommendations can be made.
