Bottom line
Pain neuroscience education is a promising, low-cost, scalable addition to pediatric chronic-pain care—most reliable for improving pain understanding and self-efficacy—but its effects on pain intensity, function, and emotions are small and inconsistent, so it is best combined with exercise and family involvement rather than used alone.

Study Summary
This PRISMA-guided systematic review synthesized 11 studies (1,076 participants, ages 6–18) testing pain neuroscience education (PNE) for children and adolescents with chronic pain. PNE consistently improved pain-related knowledge, with gains maintained at follow-up (moderate certainty of evidence), but its effects on pain intensity, physical function, and emotional outcomes such as anxiety, catastrophizing, and kinesiophobia were small and inconsistent (low-to-very-low certainty), with more favorable patterns when PNE was combined with exercise or booster sessions. Digital and gamified delivery formats proved feasible and engaging, and the few studies involving parents showed small improvements where measured. The authors conclude PNE is a promising, low-cost, scalable component of pediatric chronic-pain care—best integrated into biopsychosocial, multidisciplinary programs alongside exercise and family involvement—while noting that larger, standardized trials with longer follow-up and systematic adverse-event reporting are still needed.
Key Findings
| Finding | Detail | Impact |
|---|---|---|
| Pain knowledge improved consistently and was maintained at follow-up | All seven studies that assessed pain-related knowledge or conceptualization reported statistically significant post-intervention increases that were sustained at follow-up; this was the only outcome rated moderate certainty under GRADE. | High |
| Effects on pain intensity were small and inconsistent | Pain intensity was assessed in 6 of 11 studies; only 2 (Pas et al. and Andías et al. 2022) reported significant, sustained reductions, while others found no significant change. Certainty was rated low. The authors argue PNE acts more on cognitive, emotional, and behavioral dimensions than on the sensory intensity of pain. | High |
| Function and emotional outcomes showed modest, often non-sustained effects | Disability/function improvements were generally modest and varied by instrument and timing (low certainty). Emotional outcomes—anxiety, depression, catastrophizing, kinesiophobia—were heterogeneous and often not sustained over time, with statistical significance frequently reached only in a single study (Andías et al. 2022). | Medium |
| Combining PNE with exercise and booster sessions yielded more favorable patterns | The three studies (one research group) that combined PNE with physical activity reported positive outcomes, and repeated or booster sessions appeared to enhance impact, consistent with repeated-exposure learning. | Medium |
| Adverse events were not reported in any study | Adverse events were a pre-specified critical outcome but were not reported across the included studies, limiting safety appraisal. | Medium |
| Parental involvement was uncommon but showed small benefits where measured | Only 4 of 11 studies involved parents/caregivers (in one, caregivers were present only as companions). Parental catastrophizing decreased (low certainty), caregiver anxiety/stress showed small or non-sustained effects (very low certainty), and parental satisfaction was higher in intervention groups. | Low |

Pain intensity was assessed in 6 of 11 studies; only 2 (Pas et al. and Andías et al. 2022) reported significant, sustained reductions, while others found no significant change. Certainty was rated low. The authors argue PNE acts more on cognitive, emotional, and behavioral dimensions than on the sensory intensity of pain.
Disability/function improvements were generally modest and varied by instrument and timing (low certainty). Emotional outcomes—anxiety, depression, catastrophizing, kinesiophobia—were heterogeneous and often not sustained over time, with statistical significance frequently reached only in a single study (Andías et al. 2022).
The three studies (one research group) that combined PNE with physical activity reported positive outcomes, and repeated or booster sessions appeared to enhance impact, consistent with repeated-exposure learning.
Adverse events were a pre-specified critical outcome but were not reported across the included studies, limiting safety appraisal.
Only 4 of 11 studies involved parents/caregivers (in one, caregivers were present only as companions). Parental catastrophizing decreased (low certainty), caregiver anxiety/stress showed small or non-sustained effects (very low certainty), and parental satisfaction was higher in intervention groups.
Strengths
- Prospectively registered in PROSPERO and conducted following PRISMA, with two independent reviewers at all stages and a third for consensus
- Used design-specific risk-of-bias tools (Cochrane RoB 2, CASP, NIH) and rated certainty of evidence with GRADE
- Stratified outcomes by informant (child self-report vs. parent/caregiver proxy) and downgraded for indirectness, a strength for pediatric evidence
- Comprehensive multi-database search (PubMed, Web of Science, PEDro) with forward and backward citation tracking and author contact when eligibility was unclear
- Transparent, outcome-level synthesis using the SWiM reporting guideline given heterogeneity that precluded meta-analysis
Limitations
- Substantial heterogeneity in interventions, comparators, outcome instruments, and follow-up windows precluded meta-analysis and limited comparability
- Many included studies were small pilot, feasibility, or single-group pre-post designs, with several uncontrolled, limiting causal inference
- Certainty of evidence was low or very low for most outcomes (only pain knowledge reached moderate certainty), with frequently 1–2 studies per outcome
- Adverse events—a pre-specified critical outcome—were not reported in any study, preventing safety appraisal
- Use of non-validated pediatric questionnaires in some studies and limited blinding for self-reported outcomes; formal publication-bias assessment was not feasible
- Only two studies adhered to PedIMMPACT core outcome recommendations, and only three (from a single research group) combined PNE with exercise
Key Takeaways for Patients
What This Means for You
- 01Pain neuroscience education teaches children and families how the brain and nervous system produce and turn up pain; the strongest, most reliable benefit is a better, lasting understanding of pain.
- 02Education alone often produces only small or inconsistent changes in actual pain levels, day-to-day function, anxiety, and fear of movement—so it works best as one part of a broader plan.
- 03Outcomes tended to be better when education was combined with exercise and repeated 'booster' sessions over time.
- 04Programs delivered at school, online, or through games were practical and engaging for kids and teens.
- 05Involving parents and caregivers may help, but very few studies tested this, and no study reported on side effects, so more research is needed.
