A meta-analysis of therapeutic pain neuroscience education, using dosage and treatment format as moderator variables

Key points

1. 01TPNE had statistically significant effects on kinesiophobia, pain intensity, pain disability, and pain catastrophizing across included RCTs
2. 02Number of sessions, session duration, and number of weeks of TPNE did not significantly moderate outcomes, suggesting even brief TPNE may be sufficient
3. 03Group-based TPNE was the only significant moderator, producing a large effect size on kinesiophobia (d=0.80, p<0.05)
4. 04Whether TPNE was delivered alone or combined with other modalities did not significantly change outcomes
5. 05Social observational learning within group settings may explain the additional benefit of group TPNE on fear of movement

How it was conducted

Design

Systematic review and meta-analysis of randomized controlled trials

Databases

PubMed, PEDro, Google Scholar, SpingerLink

Population

Adults (18 years and older) with chronic musculoskeletal pain (pain present for months or more), excluding malignancy-related pain

Intervention

Therapeutic pain neuroscience education (TPNE), alone or combined with other modalities, any dosage or format

Primary outcomes

Kinesiophobia (Tampa Scale of Kinesiophobia), pain intensity (NRS/VAS), pain disability (PDI, RMDQ, ODI, NDI, FIQ and others), pain catastrophizing (Pain Catastrophizing Scale)

Moderators examined

Single vs. multiple sessions, number of sessions, minutes per session, TPNE alone vs. combined, group-based vs. non-group-based delivery

What they found

• Overall effect of TPNE on kinesiophobia: effect size -1.71 (large magnitude), z=2.76, p=0.006, 95% CI: -2.93 to -0.50
• Group-based TPNE moderator on kinesiophobia: z=-2.23, p<0.05, 95% CI: -2.70 to -0.20; between-group analysis showed group-based interventions had average effect size 0.80 (SE=0.40), z=2.20, p<0.05, 95% CI: 0.09 to 1.50
• Non-group-based TPNE on kinesiophobia: average effect size -0.65 (SE=0.65), z=-1.22, p=0.22, 95% CI: -1.71 to 0.40 (not statistically significant)
• Pain intensity, pain disability, and pain catastrophizing all showed statistically significant overall effects and heterogeneity on moderator analysis (specific values in Table 3)
• Moderator analyses for dosage variables (number of sessions, session length, weeks of treatment) were not statistically significant for any outcome
• No publication bias identified across any outcome measure based on funnel plot analyses, Begg and Mazumdar rank correlation, and Rosenthal Fail-safe N

Limitations

• Effect sizes at different post-intervention time points were not separately analysed, so short-term versus long-term trajectories of benefit remain unclear
• Separate moderator analyses for the different treatment techniques combined with TPNE could not be performed due to heterogeneity of co-interventions
• Total number of included studies and total sample size are not clearly reported in the extracted text, limiting precision of pooled estimates
• Group-based TPNE moderator analysis did not distinguish whether group sessions were delivered alone or alongside other modalities

Why it matters

For patients

People with chronic musculoskeletal pain can expect meaningful reductions in fear of movement, pain intensity, disability, and catastrophizing from TPNE regardless of how many sessions they attend, and joining a group-based programme may provide extra benefit for overcoming movement fear.

For clinicians

TPNE improves all four key pain outcomes in chronic musculoskeletal pain, and clinicians can prioritise group-based delivery to maximise reductions in kinesiophobia without needing to worry excessively about achieving a specific session dose.

For readers

This meta-analysis confirms TPNE as an effective pain management modality and highlights group-based delivery as a potentially important format variable, while identifying gaps around optimal dosage definition and long-term outcome tracking.
