Bottom line
Adding pain neuroscience education to therapeutic exercise produced greater short-term improvements in pain-disability, pain catastrophizing, and fear-avoidance beliefs than exercise alone in chronic neck pain, though the self-efficacy advantage was not statistically significant and follow-up was lacking.

Study Summary
This three-arm randomized controlled trial of 72 adults with chronic nonspecific neck pain compared therapeutic exercises alone, therapeutic exercises combined with pain neuroscience education (PNE), and a no-intervention control over six weeks. Both active interventions outperformed the control on pain-disability, pain catastrophizing, fear-avoidance beliefs, and pain self-efficacy. Adding PNE to exercise produced significantly greater improvements in pain-disability, pain catastrophizing, and fear-avoidance beliefs than exercise alone, while the difference in pain self-efficacy between the two active groups was not statistically significant. The authors note short follow-up and a small sample, calling for longer studies.
Key Findings
| Finding | Detail | Impact |
|---|---|---|
| Combining pain neuroscience education with exercise beat exercise alone on most outcomes | The combined group showed significantly greater improvements than exercise alone in pain-disability (NPAD, p ≤ 0.001), fear-avoidance beliefs (FABQ, p = 0.041), and pain catastrophizing (PCS, p = 0.044). | High |
| No significant between-group difference for pain self-efficacy | For pain self-efficacy (PSEQ), there was no statistically significant difference between the two intervention groups (p = 0.99), though the authors state the combined group had a greater effect on increasing self-efficacy. | Medium |
| Both active interventions outperformed the no-treatment control | Both exercise alone and the combined group were significantly superior to the control group across all measured outcomes (p ≤ 0.001 favoring experimental groups versus control). | High |
| Interventions were well tolerated with high adherence | Adherence was high (94% of sessions in the exercise-alone group and 89% in the combined group), and no adverse events were reported. | Low |
Strengths
- Randomized controlled design with three arms, including a control group and prospective trial registration (UMIN000044585)
- Blinded assessor and concealed, computer-generated random allocation
- Used validated, condition-relevant outcome measures (NPAD, PCS, FABQ, PSEQ), with Persian-validated versions
- High adherence (89-94% of sessions) and no reported adverse events
- Sample size pre-specified via a power calculation based on a pilot study
Limitations
- Short 6-week intervention with no follow-up, so durability of benefits is unknown
- Small sample size, limiting generalizability to the broader population
- No pain-neuroscience-education-alone arm, so the independent effect of PNE could not be isolated
- Some relevant cognitive and quality-of-life outcomes (e.g., distress, quality of life) were not measured
- Single-region recruitment (Tehran, Iran), which may limit applicability elsewhere
Key Takeaways for Patients
What This Means for You
For long-standing neck pain, doing neck and shoulder strengthening exercises helped reduce pain, disability, and pain-related fear compared with no treatment.
Adding pain neuroscience education - learning how pain works in the nervous system - on top of exercise gave bigger improvements in disability, catastrophic thinking about pain, and fear of movement than exercise on its own.
The added benefit for confidence in coping with pain (self-efficacy) was not statistically clear, though it trended in favor of the combined approach.
This was a short 6-week study with a relatively small group and no follow-up, so it is not yet known how long these benefits last.
