Does Pain Neuroscience Education and Cognition-Targeted Motor Control Training Improve Cervical Motor Output? Secondary Analysis of a Randomized Clinical Trial

Pain neuroscience education for reducing pain and kinesiophobia in patients with chronic neck pain: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Chronic neck pain (CNP) is a common musculoskeletal disorder. Pain neuroscience education (PNE) is a promising nonpharmacological intervention for CNP, however, its effectiveness remains unclear. This systematic review and meta-analysis aimed to evaluate the effectiveness of PNE in treating CNP.

METHODS

Electronic databases from inception to February 2023 were searched for randomized controlled trials (RCTs) on the effects of PNE on CNP. The primary outcome was the change in pain intensity, and the secondary outcome was improvement in kinesiophobia, standardized using Hedges' g. Two authors independently scrutinized eligible articles, extracted data and assessed quality; a random-effects model was employed for data pooling.

RESULTS

In total, seven RCTs comprising 479 participants were included and demonstrated that PNE significantly reduced pain intensity (Hedges' g = -0.730, 95% CI = -1.340 to -0.119, p = 0.019, I2  = 89.288%). Subgroup analysis revealed that the adult group experienced significant pain reduction after PNE, whereas the adolescent group did not. PNE also reduced kinesiophobia which was evaluated in four of seven RCTs (Hedges' g = -0.444, 95% CI = -0.735 to -0.154, p = 0.003, I2  = 36.822%). The meta-regression analysis indicated that an increased intervention duration contributed to greater pain reduction. No adverse events were reported following PNE or the control treatment.

CONCLUSIONS

PNE effectively reduced pain intensity and kinesiophobia in patients with CNP. A longer PNE time leads to greater pain reduction and is more effective in adults than in adolescents. Further studies are required to examine the long-term effects on CNP management.

SIGNIFICANCE

This is the first meta-analysis evaluating the effectiveness of treating chronic neck pain with pain neuroscience education. Pain neuroscience education is successful in reducing pain and decreasing kinesiophobia in the chronic neck pain population. Longer treatment time leads to greater pain reduction.

Exercise therapy including the cervical extensor muscles in individuals with neck pain: A systematic review

OBJECTIVE

To review the use (dosage parameters and combination with other therapeutic interventions) of cervical extensor muscle exercises and their effect on pain, disability (primary outcomes), range of motion, endurance and strength (secondary outcomes) in people with neck pain.

DATA SOURCES

An extensive literature search was conducted through MEDLINE (Ovid), Scopus (Elsevier) and Physiotherapy Evidence Database (PEDro) up to May 2023. The reference lists of all included studies and relevant reviews were screened for additional studies.

REVIEW METHODS

Randomised controlled trials reporting the use of cervical extensor muscle exercises (alone or combined) applied to adults with idiopathic or traumatic neck pain were included. Study selection, data extraction and critical appraisal (PEDro assessment scale) were performed by two blinded reviewers. Data extraction included dosage parameters, other modalities combined with these exercises and outcomes.

RESULTS

Thirty-five randomised controlled trails (eight of which were complementary analyses) with 2409 participants fulfilled the inclusion criteria. Twenty-six were of moderate to high quality. In most studies, cervical extensor muscle exercises were combined with various other therapeutic modalities and applied at different dosages. Only two studies (one high and one low quality) specifically assessed their effectiveness. The high-quality study showed significant improvements in neck pain and disability, pressure point threshold and neck mobility after both low load and high load training for 6 weeks.

CONCLUSION

The results suggest cervical extensor muscle exercises may reduce neck pain and disability; however firm conclusions cannot be drawn because of the few studies that addressed this question and the heterogeneity of the dosage parameters.

Pilot study on the effects of a culturally-sensitive and standard pain neuroscience education for Hausa-speaking patients with chronic neck pain

PURPOSE

To pilot feasibility and assess preliminary effectiveness of standard and culture-sensitive Pain Neuroscience Education (PNE) among Hausa-speaking patients with Chronic Neck Pain (CNP).

METHODS

Adverts (online & clinic-based) were used to recruit Hausa-speaking patients with nonspecific CNP in Kano, Nigeria. Selected participants were randomized to culture-sensitive PNE (CSPNE), standard PNE (PNE), or control groups. Each group received bi-weekly sessions of exercise therapy for 6 weeks. Two sessions of PNE plus a home-based session were administered before exercise therapy in the PNE groups. Primary (pain-intensity and disability) and secondary (pain-knowledge, pain catastrophizing, and quality of life) outcomes were measured. The study was pre-registered (PACTR201902788269426).

RESULTS

Fifty-three (out of 64) participants met the inclusion criteria. The majority of them were recruited through radio adverts (83%). Interventions were successfully administered and data collection was completed for the participants. About 15% and 17% drop-out rate was recorded before intervention (post-randomization) and during follow-up, respectively. Main results indicated that significant within-group improvements in disability and pain knowledge scores were found in favor of the PNE groups.

CONCLUSION

Culture-sensitive and standard PNE plus exercise therapy are feasible for Hausa patients with CNP, and current findings indicate support for reducing disability and increasing pain knowledge among them.Implications for rehabilitationBoth standard PNE and culture-sensitive PNE are feasible for administration as interventions for Hausa-speaking patients with CNP.Radio adverts may be necessary for patients recruitment in addition to specialists' referrals.Culturally sensitive PNE materials may be more desirable as an intervention option due to the low literacy level among the Hausa population.

Neuroscience Education as Therapy for Migraine and Overlapping Pain Conditions: A Scoping Review

BACKGROUND

Neuroscience Education Therapy (NET) has been successfully used for numerous overlapping pain conditions, but few studies have investigated NET for migraine.

OBJECTIVE

We sought to (1) review the literature on NET used for the treatment of various pain conditions to assess how NET has been studied thus far and (2) recommend considerations for future research of NET for the treatment of migraine.

DESIGN/METHODS

Following the PRISMA guideline for scoping reviews (PRISMA-ScR) Co-author (TR), a Medical Librarian, searched the MEDLINE, PsychInfo, Embase & Cochrane Central Clinical Trials Registry databases for peer-reviewed articles describing NET to treat migraine and other chronic pain conditions. Each citation was reviewed by two trained independent reviewers. Conflicts were resolved through consensus.

RESULTS

Overall, a NET curriculum consists of the following topics: pain does not equate to injury, pain is generated in the brain, perception, genetics, reward systems, fear, brain plasticity, and placebo/nocebo effects. Delivered through individual, group, or a combination of individual and group sessions, NET treatments often incorporate exercise programs and/or components of other evidence-based behavioral treatments. NET has significantly reduced catastrophizing, kinesiophobia, pain intensity, and disability in overlapping pain conditions. In migraine-specific studies, when implemented together with traditional pharmacological treatments, NET has emerged as a promising therapy by reducing migraine days, pain intensity and duration, and acute medication intake.

CONCLUSION

NET is an established treatment for pain conditions, and future research should focus on refining NET for migraine, examining delivery modality, dosage, components of other behavioral therapies to integrate, and migraine-specific NET curricula.
