Pain biology education and exercise classes compared to pain biology education alone for individuals with chronic low back pain: A pilot randomised controlled trial

Identifying pain profiles in employees including work-related factors and pain perceptions: a cross-sectional study in Belgian companies

OBJECTIVES

Studies usually investigate a limited number or a predefined combinations of risk factors for sickness absence in employees with pain. We examined frequently occurring combinations across a wide range of work-related factors and pain perceptions.

DESIGN

Cross-sectional study.

SETTING

Belgian companies that are under supervision of IDEWE, an external service for prevention and protection at work.

PARTICIPANTS

In total, 249 employees experiencing pain for at least 6 weeks were included and filled out an online survey.

OUTCOMES

Latent profile analysis was used to differentiate profiles of work-related factors (physical demands, workload, social support and autonomy) and pain perceptions (catastrophising, fear-avoidance beliefs and pain acceptance). Subsequently, profiles were compared on sociodemographics (age, gender, level of education, work arrangement, duration of complaints, multisite pain and sickness absence in the previous year) and predictors of sickness absence (behavioural intention and perceived behavioural control).

RESULTS

Four profiles were identified. Profile 1 (38.2%) had favourable scores and profile 4 (14.9%) unfavourable scores across all indicators. Profile 2 (33.3%) had relatively high physical demands, moderate autonomy levels and favourable scores on the other indicators. Profile 3 (13.7%) showed relatively low physical demands, moderate autonomy levels, but unfavourable scores on the other indicators. Predictors of profiles were age (OR 0.93 and 95% CI (0.89 to 0.98)), level of education (OR 0.28 and 95% CI (0.1 to 0.79)) and duration of sickness absence in the previous year (OR 2.29 and 95% CI (0.89 to 5.88)). Significant differences were observed in behavioural intention (χ2=8.92, p=0.030) and perceived behavioural control (χ2=12.37, p=0.006) across the four profiles.

CONCLUSION

This study highlights the significance of considering the interplay between work-related factors and pain perceptions in employees. Unfavourable scores on a single work factor might not translate into maladaptive pain perceptions or subsequent sickness absence, if mitigating factors are in place. Special attention must be devoted to employees dealing with unfavourable working conditions along with maladaptive pain perceptions. In this context, social support emerges as an important factor influencing sickness absence.

Pain Education and Virtual Reality Improves Pain, Pain-related Fear of Movement, and Trunk Kinematics in Individuals With Persistent Low Back Pain

OBJECTIVES

To evaluate the effect of combining pain education and virtual reality (VR) exposure therapy using a cognitive-behavioral therapy-informed approach (virtual reality-based cognitive behavioral therapy [VR-CBT]) on pain intensity, fear of movement, and trunk movement in individuals with persistent low back pain.

MATERIALS AND METHODS

Thirty-seven participants were recruited in a single cohort repeated measures study, attending 3 sessions 1 week apart. The VR-CBT intervention included standardized pain education (session 1) and virtual reality-based exposure therapy (VRET; session 2) incorporating gameplay with mixed reality video capture and reflective feedback of performance. Outcome measures (pain intensity, pain-related fear of movement (Tampa Scale of Kinesiophobia), and trunk kinematics during functional movements (maximum amplitude and peak velocity) were collected at baseline (session 1) and 1 week after education (session 2) and VRET (session 3). One-way repeated measures analysis of variances evaluated change in outcomes from baseline to completion. Post hoc contrasts evaluated effect sizes for the education and VR components of VR-CBT.

RESULTS

Thirty-four participants completed all sessions. Significant ( P < 0.001) reductions were observed in mean (SD) pain (baseline 5.9 [1.5]; completion 4.3 [2.1]) and fear of movement (baseline 42.6 [6.4]; completion 34.3 [7.4]). Large effect sizes (Cohen d ) were observed for education (pain intensity: 0.85; fear of movement: 1.28), whereas the addition of VRET demonstrated very small insignificant effect sizes (pain intensity: 0.10; fear of movement: 0.18). Peak trunk velocity, but not amplitude, increased significantly ( P < 0.05) across trunk movement tasks.

CONCLUSION

A VR-CBT intervention improved pain, pain-related fear of movement, and trunk kinematics. Further research should explore increased VR-CBT dosage and mechanisms underlying improvement.

Observational pilot study on the influence of an app-based self-management program on the quality of life of women with endometriosis

PURPOSE

Endometriosis can significantly impair the quality of life of those affected. Multimodal self-help measures are recommended but often difficult to access. Smartphone apps have been shown to improve the quality of life for other conditions with chronic pain. The aim of this study was to examine whether there is evidence of beneficial effects of the smartphone app "Endo-App®" and whether a multicenter randomized controlled trial should be planned to substantiate these effects.

METHODS

In a sample of N = 106 women affected by endometriosis the present study determined the influence of the use of Endo-App® on their quality of life. Among others, the validated questionnaire Endometriosis Health Profile from Oxford University was used for this purpose.

RESULTS

The use of Endo-App® lead to a highly significant improvement in quality of life already after 2 weeks. A statistically significant change was found for nine out of ten measured variables of quality of life. A series of further analyses validated that the measured positive effects were not due to other confounding factors.

CONCLUSION

In summary, the results indicate that the quality of life of women with endometriosis improved by the digital self-management tool Endo-App®. More studies are needed to further explore the influence of the app on quality of life and as confirmatory evidence of beneficial effects. For this purpose, a randomized controlled trial should be conducted over a longer period of time.

TRIAL REGISTRATION

This trial is registered at clinicaltrials.gov under the registration number NCT05528601 on August 18, 2022. It was retrospectively registered.

Acceptability of multimodal and multidisciplinary group-based program for chronic low back pain: a qualitative study

BACKGROUND

The Programa d'Atenció Integral pels Pacients amb Dolor Crònic (PAINDOC) is a multimodal and multidisciplinary group-based program that integrates pain neuroscience education, mindfulness meditation, pain psychotherapy, Empowered Relief, and therapeutic exercise. It serves as a therapeutic option for individuals with chronic low back pain, providing them with comprehensive adaptive strategies for pain management.

OBJECTIVE

This qualitative study explores participants' retrospective acceptability of the PAINDOC Program.

METHODS

To ensure demographic variability and information power, a purposive sampling approach was applied. Twelve participants were interviewed through three focus groups, supplemented with four individual semi-structured interviews. Data was analyzed using reflexive thematic analysis and evaluated based on the Therapeutic Framework of Acceptability.

RESULTS

Participants provide positive feedback regarding active pain coping strategies and improved self-management. While certain aspects of the Program were more emphasized, participants integrated tools from all components. Strategies included pain reconceptualization, positive self-talk, or problem-solving. The Program's ethicality was closely linked to individual values and may also be influenced by time constraints of certain program elements, the immediate effects of specific approaches, participant perceptions, and individual preferences.

CONCLUSIONS

The findings provide valuable insights into the acceptability of the PAINDOC Program, guiding future improvements and the development of similar interventions.

Development and Evaluation of the Abdominal Pain Knowledge Questionnaire (A-PKQ) for Children and Their Parents

BACKGROUND

Abdominal pain is a common and often debilitating issue for children and adolescents. In many cases, it is not caused by a specific somatic condition but rather emerges from a complex interplay of bio-psycho-social factors, leading to functional abdominal pain (FAP). Given the complex nature of FAP, understanding its origins and how to effectively manage this condition is crucial. Until now, however, no questionnaire exists that targets knowledge in this specific domain. To address this, the Abdominal Pain Knowledge Questionnaire (A-PKQ) was developed.

METHODS

Two versions were created (one for children and one for parents) and tested in four gastroenterology clinics and one specialized pain clinic in Germany between November 2021 and February 2024. Children between 8 and 17 years of age (N = 128) and their accompanying parents (N = 131) participated in the study. Rasch analysis was used to test the performance of both versions of the questionnaire.

RESULTS

The original questionnaires exhibited good model and item fit. Subsequently, both questionnaires were refined to improve usability, resulting in final versions containing 10 items each. These final versions also demonstrated good model and item fit, with items assessing a variety of relevant domains.

CONCLUSION

The A-PKQ is an important contribution to improving assessment in clinical trials focused on pediatric functional abdominal pain.

Pain neuroscience education improves post-traumatic stress disorder, disability, and pain self-efficacy in veterans and service members with chronic low back pain: Preliminary results from a randomized controlled trial with 12-month follow-up

Post-traumatic stress disorder (PTSD) and chronic low back pain (CLBP) are frequently co-morbid. Some research suggests that PTSD and CLBP may share common neurobiological mechanisms related to stress. Traditional biomedical education may be ineffective for PTSD and CLBP, especially when co-morbid. The purpose of this study is to determine if pain neuroscience education (PNE) is more effective than traditional education in reducing PTSD, disability, pain, and maladaptive beliefs in patients with CLBP. Participants with CLBP and possible PTSD/PTSD-symptoms were recruited for this study. Participants were randomly allocated to a PNE group or a traditional education group. The intervention included 30 minutes of education followed by a standardized exercise program once a week for 4-weeks with a 4 and 8-week follow-up and healthcare utilization assessed at 12-months. Forty-eight participants consented for this research study with 39 allocated to treatment (PNE n = 18, traditional n = 21). PNE participants were more likely to achieve a clinically meaningful reduction in PTSD symptoms and disability at short-term follow-up. At 12-months, the PNE group utilized healthcare with 76% lower costs. In participants with CLBP, PNE may reduce hypervigilance toward pain and improve PTSD symptoms. Participants who received PNE were more confident body-tissues were safe to exercise. These beliefs about pain could contribute to a decrease in perceived disability and healthcare consumption for CLBP.

How do people with chronic low back pain perceive specific and general exercise? A mixed methods survey

PURPOSE

Exercise prescriptions for chronic low back pain (CLBP) often utilize reductionistic, trunk-focused exercise aimed at addressing proposed pain mechanisms. It is unknown if the use of these trunk-focused exercises imply beliefs to people with CLBP about the rationale for their use (e.g., etiology), even without concurrent biomedical narratives. This study aimed to explore people's perceptions of specific and general exercise without an accompanying narrative when experiencing CLBP.

METHODS

An anonymous online survey was distributed. Mixed methods were utilized for analysis. Six-point Likert scales categorized people's beliefs about individual exercises. Open-ended questions were used to gather further beliefs which were then coded into themes.

RESULTS

People with CLBP perceived specific exercise as more beneficial than general exercise. Eight themes and five subthemes were defined. A high volume of positive beliefs were centered around strengthening the low back and abdominal musculature, emphasizing the importance of correct technique. Negative beliefs were held against spinal flexion and external load. Both positive and negative beliefs were underpinned by spinal/pelvic stability being important as well as certain exercises being achievable or not.

CONCLUSION

This study demonstrated that people with CLBP consider specific exercises to be more beneficial than general exercises for CLBP. Specific exercises irrespective of an accompanying narrative can imply meaning about the intent of an exercise. Understanding this requires practitioners to be mindful when prescribing and communicating exercise.

Pain neuroscience education for patients with chronic pain: A scoping review from teaching-learning strategies, educational level, and cultural perspective

OBJECTIVE

(1) To identify the characteristics of PNE programs in terms of teaching-learning strategies, session modality, content delivery format, number of sessions, total minutes and instructional support material used in patients with chronic musculoskeletal pain, (2) to describe PNE adaptations for patients with different educational levels or cultural backgrounds, and (3) to describe the influence of the patient's educational level or cultural background on the effects of PNE.

METHODS

The PRISMA guideline for scoping reviews was followed. Nine databases were systematically searched up to July 8, 2023. Articles that examined clinical or psychosocial variables in adults with chronic musculoskeletal pain who received PNE were included.

RESULTS

Seventy-one articles were included. Studies found benefits of PNE through passive/active teaching-learning strategies with group/individual sessions. However, PNE programs presented great heterogeneity and adaptations to PNE were poorly reported. Most studies did not consider educational level and culture in the effects of PNE.

CONCLUSIONS

Despite the large number of studies on PNE and increased interest in this intervention, the educational level and culture are poorly reported in the studies.

PRACTICAL IMPLICATIONS

It is recommended to use passive and/or active teaching-learning strategies provided in individual and/or group formats considering the patient's educational level and culture.

Effectiveness of in-group versus individually administered pain neuroscience education on clinical and psychosocial outcomes in patients with chronic low back pain: randomized controlled study protocol

Objective

(1) This trial will compare the clinical and psychosocial effectiveness of in-group and individually pain neuroscience education (PNE) in patients with chronic low back pain (CLBP). In addition, (2) the influence of social determinants of health on post-treatment results will be analyzed.

Methods

A three-arm randomized controlled trial will be conducted. Sixty-nine participants with CLBP will be recruited in a 1:1:1 ratio. Participants, assessor, and statistician will be blinded to group assignment. The PNE intervention will be adapted to the context of the participants. An experimental group (n = 33) will receive PNE in an in-group modality, the other experimental group (n = 33) will receive PNE in an individually modality and the control group (n = 33) will continue with usual care. Additionally, participants will be encouraged to stay active by walking for 20-30 min 3-5 times per week and will be taught an exercise to improve transversus abdominis activation (bracing or abdominal following). The outcome measures will be fear avoidance and beliefs, pressure pain threshold, pain self-efficacy, catastrophizing, pain intensity, and treatment expectation. Outcome measures will be collected at one-week before intervention, immediately post-intervention, and four-weeks post-intervention.

Conclusion

The innovative approach of PNE oriented to fear beliefs proposed in this study could broaden the application strategies of this educational therapeutic modality. Impact. Contextualized PNE delivered by physical therapist could be essential to achieve a good cost-effectiveness ratio of this intervention to improve the clinical condition of people with CLBP.

Physiotherapeutic and non-conventional approaches in patients with chronic low-back pain: a level I Bayesian network meta-analysis

Chronic low back pain (cLBP) is a major cause of disability and healthcare expenditure worldwide. Its prevalence is increasing globally from somatic and psychosocial factors. While non-pharmacological management, and in particular physiotherapy, has been recommended as a first-line treatment for cLBP, it is not clear what type of physiotherapeutic approach is the most effective in terms of pain reduction and function improvement. This analysis is rendered more difficult by the vast number of available therapies and a lack of a widely accepted classification that can effectively highlight the differences in the outcomes of different management options. This study was conducted according to the PRISMA guidelines. In January 2024, the following databases were accessed: PubMed, Web of Science, Google Scholar, and Embase. All the randomised controlled trials (RCTs) which compared the efficacy of physiotherapy programs in patients with cLBP were accessed. Studies reporting on non-specific or mechanical cLPB were included. Data concerning the Visual Analogic Scale (VAS) or numeric rating scale (NRS), Roland Morris Disability Questionnaire (RMQ) and Oswestry Disability Index (ODI). Data from 12,773 patients were collected. The mean symptom duration was 61.2 ± 51.0 months and the mean follow-up was 4.3 ± 5.9 months. The mean age was 44.5 ± 9.4 years. The mean BMI was 25.8 ± 2.9 kg/m2. The Adapted Physical Exercise group evidenced the lowest pain score, followed by Multidisciplinary and Adapted Training Exercise/Complementary Medicine. The Adapted Physical Exercise group evidenced the lowest RMQ score followed by Therapeutic Exercises and Multidisciplinary. The Multidisciplinary group evidenced the lowest ODI score, followed by Adapted Physical Exercise and Physical Agent modalities. Within the considered physiotherapeutic and non-conventional approaches to manage nonspecific and/or mechanic cLBP, adapted physical exercise, physical agent modalities, and a multidisciplinary approach might represent the most effective strategy to reduce pain and disability.

Measuring objective physical activity in people with chronic low back pain using accelerometers: a scoping review

Purpose

Accelerometers can be used to objectively measure physical activity. They could be offered to people with chronic low back pain (CLBP) who are encouraged to maintain an active lifestyle. The aim of this study was to examine the use of accelerometers in studies of people with CLBP and to synthesize the main results regarding the measurement of objective physical activity.

Methods

A scoping review was conducted following Arksey and O'Malley's framework. Relevant studies were collected from 4 electronic databases (PubMed, Embase, CINHAL, Web of Science) between January 2000 and July 2023. Two reviewers independently screened all studies and extracted data.

Results

40 publications out of 810 citations were included for analysis. The use of accelerometers in people with CLBP differed across studies; the duration of measurement, physical activity outcomes and models varied, and several limitations of accelerometry were reported. The main results of objective physical activity measures varied and were sometimes contradictory. Thus, they question the validity of measurement methods and provide the opportunity to discuss the objective physical activity of people with CLBP.

Conclusions

Accelerometers have the potential to monitor physical performance in people with CLBP; however, important technical limitations must be overcome.

Effectiveness of an exercise intervention based on preactivation of the abdominal transverse muscle in patients with chronic nonspecific low back pain in primary care: a randomized control trial

BACKGROUND

Low back pain is one of the most common disabling pathologies in humanity worldwide. Physical exercises have been used in recent decades to reduce the pain, improve the functionality of the lumbar spine and avoid relapses. The purpose of the study is to analyze the effect of a program based on re-education exercises involving preactivation of the abdominal transverse muscle compared to conventional treatment in adults with chronic nonspecific low back pain.

METHODS

A two-arm, single-blind randomized control trial with 35 primary care patients with chronic nonspecific low back pain. Both groups received a 4-week intervention. Data were collected at baseline and at the end of the intervention. Sixteen patients participated in the intervention group, and 19 patients in the control group.

RESULTS

For the experimental group, the outcomes of disability and activation of the abdominal transverse muscle decreased significantly (MD -2.9; CI 95% -5.6 to -0.35; η2 = 0.14; p = 0.028) and (MD 2.3; CI 95% 0.91 to 3.67; η2 = 0.25; p = 0.002) respectively, with a large effect size, compared to the control group. There were no differences between the groups in pain intensity, thickness, and resistance of the transverse abdominal muscle.

CONCLUSION

A 4-week specific program based on re-education exercises of the preactivation of the abdominal transverse muscle is more effective than conventional treatment for reducing disability and increasing the activation of the abdominal transverse muscle measured by VAS scale and PBU.

Examining the influence of pain neuroscience education followed by a Pilates exercises program in individuals with knee osteoarthritis: a pilot randomized controlled trial

BACKGROUND

Knee osteoarthritis (OA) is a multifactorial form of rheumatic condition contributing to physical and psychological factors. Treatments have been provided solely and often compared with each other. An alternative view is that combined treatments addressing physical and psychological factors may result in more benefits. This study aimed to investigate the effect of pain neuroscience education (PNE) followed by Pilates exercises (PEs) in participants with knee OA, compared to PE alone.

METHODS

In this two-arm assessor-blind pilot randomized controlled trial, fifty-four community-dwelling adults with knee OA were randomly assigned to the PNE followed by PEs and PEs groups (27 in each group). The study was conducted between early July 2021 and early March 2022 at the university's health center. Primary outcomes were Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) subscales of pain and physical limitation and secondary outcomes were Pain Catastrophizing Scale, Tampa Scale for Kinesiophobia, Pain Self-Efficacy Questionnaire, and Timed "Up & Go" test covering function. The primary and secondary outcomes were measured at baseline and eight weeks post-treatment. A general linear mixed model was used for between-group comparison with a statistical significance level of 0.05.

RESULTS

Significant within-group differences were observed in all outcomes in both groups at post-treatment. There were no statistically between-group differences in pain (adjusted mean difference: -0.8; 95% CI -2.2 to 0.7; p = 0.288), physical limitation (adjusted mean difference: -0.4; 95% CI -4 to 3.1; p = 0.812) and function (adjusted mean difference: -0.8; 95% CI -1.8 to 0.1; p = 0.069) at eight weeks. For pain catastrophizing (adjusted mean difference: -3.9; 95% CI -7.2 to -0.6; p = 0.021), kinesiophobia (adjusted mean difference: -4.2; 95% CI -8.1 to -0.4; p = 0.032), and self-efficacy (adjusted mean difference: 6.1; 95% CI 0.7 to 11.5; p = 0.028) statistically between-group improvements were observed favoring PNE followed by PEs group after the treatment.

CONCLUSIONS

Combining PNE with PEs could have superior effects on psychological characteristics but not on pain, physical limitation, and function, compared to PEs alone. This pilot study emphasizes the need to investigate the combined effects of different interventions.

Supervised exercise with or without laser-guided feedback for people with non-specific chronic low back pain. A randomized controlled clinical trial

BACKGROUND

Among the most effective therapeutic interventions in non-specific chronic low back pain (NSCLBP), clinical practice guidelines highlight exercise therapy and patient education; However, regarding the combined intervention of exercise and Pain Neuroscience Education (PNE), there is no consensus on the most effective form of exercise.

OBJETIVE

To find out what changes occurred after the application of two exercise modalities [Supervised Exercise (SE) and Laser-Guided Exercise (LGE)] and PNE on pain, pain pressure thresholds, disability, catastrophizing, kinesiophobia and lumbar proprioception in subjects with NSCLBP.

METHODS

Single-blind randomized clinical controlled trial. 60 subjects with NSCLBP. Both groups performed a a total of 16 therapeutic exercise sessions and 8 Pain Neuroscience Education sessions. With the Laser-Guided Exercise Therapy group performing laser-guided exercises.

RESULTS

A significant decrease was observed for pain intensity for both groups between baseline and post-intervention and the 3 month follow-up (p < 0.001). There was a significant between-group difference between baseline and post-intervention scores in terms of pain intensity and kinesiophobia in favour of the LGE group.

CONCLUSION

Supervised exercise with or without laser feedback, when combined with PNE, reduces pain intensity, disability, pain catastrophizing, kinesiophobia and improves proprioception and PPTs in patients with NSCLBP. At a 3-month follow-up, the combination of LGE plus PNE is most effective for reducing pain intensity.

Effect of Pain Neuroscience Education with Conventional Physiotherapy via Telerehabilitation on Pain Catastrophizing and Function in Patients with Osteoarthritis Knee: A Randomized Controlled Trial

Aim

By explaining to the patient the biological processes underneath their pain condition, pain neuroscience education (PNE) is a form of educational intervention that aims to relieve pain and impairment.

Materials and Methods

Patients with knee osteoarthritis (OA) referred to outpatient physiotherapy clinic in India during August 2021 to June 2022 were asked to participate. Out of the eligible patients, 35 were randomly assigned to PNE group and 35 to the control group. Self-reports of Pain Catastrophizing Scale (PCS), Patient Specific Function Scale (PSFS), and Numerical Pain Rating Scale (NPRS) were recorded at baseline (T1) and at 2 weeks (T2).

Results

After 2 weeks of follow-up, all the three outcome measures were found to be significant in the PNE group. The results of the unpaired t-test revealed statistically significant result posttest for PCS (mean difference 11.4) and NPRS (mean difference 1.20). There was no mean difference found in the patient function (PSFS) between groups.

Conclusion

The results suggest that adding a program of PNE to conventional physiotherapy exercises led to a greater reduction in pain catastrophization, patient-specific function, and pain intensity rather than conventional physiotherapy alone in patients with knee OA at 2 weeks' follow-up.

Effectiveness of Pain Neuroscience Education in Patients with Chronic Musculoskeletal Pain and Central Sensitization: A Systematic Review

OBJECTIVE

To collect the available evidence about the effectiveness of pain neuroscience education (PNE) on pain, disability, and psychosocial factors in patients with chronic musculoskeletal (MSK) pain and central sensitization (CS).

METHODS

A systematic review was conducted. Searches were performed on Pubmed, PEDro, and CINAHL, and only randomized controlled trials (RCTs) enrolling patients ≥18 years of age with chronic MSK pain due to CS were included. No meta-analysis was conducted, and qualitative analysis was realized.

RESULTS

15 RCTs were included. Findings were divided for diagnostic criteria (fibromyalgia-FM, chronic fatigue syndrome-CFS, low back pain-LBP, chronic spinal pain-CSP). PNE has been proposed as a single intervention or associated with other approaches, and different measures were used for the main outcomes considered. Conclusions, practice implication: PNE is effective in improving pain, disability, and psychosocial factors in patients with fibromyalgia, chronic low back pain (CLBP)-especially if associated with other therapeutic approaches-and also in patients with CFS and CSP. Overall, PNE seems to be more effective when proposed in one-to-one oral sessions and associated with reinforcement elements. However, specific eligibility criteria for chronic MSK pain due to CS are still lacking in most RCTs; therefore, for future research, it is mandatory to specify such criteria in primary studies.

Effectiveness of patient education plus motor control exercise versus patient education alone versus motor control exercise alone for rural community-dwelling adults with chronic low back pain: a randomised clinical trial

BACKGROUND

Chronic low back pain (CLBP) is a common health problem in rural Nigeria but access to rehabilitation is limited. Current clinical guidelines unanimously recommend patient education (PE) including instruction on self-management, and exercises as frontline interventions for CLBP. However, the specific content of these interventions and how they are best delivered remain to be well-described, particularly for low-resource communities. This study determined the effectiveness of PE plus motor control exercise (MCE) compared with either therapy alone among rural community-dwelling adults with CLBP.

METHODS

A single-blind, three-arm parallel-group, randomised clinical trial including 120 adult rural dwellers (mean [SD] age, 46.0 [14.7] years) with CLBP assigned to PE plus MCE group (n = 40), PE group (n = 40), and MCE group (n = 40) was conducted. The PE was administered once weekly and the MCE twice weekly. Each group also received stretching and aerobic exercises twice weekly. All interventions were administered for 8 weeks. Blinded assessments for pain intensity and disability level as primary outcomes, and quality of life, global perceived recovery, fear-avoidance beliefs, pain catastrophising, back pain consequences belief and pain medication use as secondary outcomes were conducted at baseline, 8-week (immediately after intervention) and 20-week follow-ups.

RESULTS

All the groups showed significant improvements in all the primary and secondary outcomes evaluated over time. Compared with PE alone, the PE plus MCE showed a significantly greater reduction in pain intensity by an additional -1.15 (95% confidence interval [CI], -2.04 to -0.25) points at the 8-week follow-up and -1.25 (95% CI, -2.14 to -0.35) points at the 20-week follow-up. For disability level, both PE plus MCE and MCE alone showed a significantly greater improvement compared with PE alone by an additional -5.04% (95% CI, -9.57 to -0.52) and 5.68% (95% CI, 1.15 to 10.2) points, respectively, at the 8-week follow-up, and -5.96% (95% CI, -9.84 to -2.07) and 6.57% (95% CI, 2.69 to 10.4) points, respectively, at the 20-week follow-up. For the secondary outcomes, at the 8-week follow-up, PE plus MCE showed a significantly greater reduction in fear-avoidance beliefs about physical activity compared with either therapy alone, and a significantly greater reduction in pain medication use compared with PE alone. However, compared with PE plus MCE, PE alone showed a significantly greater reduction in pain catastrophising at all follow-up time points, and a significantly greater improvement in back pain consequences belief at the 20-week follow-up. Additionally, PE alone compared with MCE alone showed a significantly greater improvement in back pain consequences belief at all follow-up time points. No significant between-group difference was found for other secondary outcomes.

CONCLUSIONS

Among rural community-dwelling adults with CLBP, PE plus MCE led to greater short-term improvements in pain and disability compared with PE alone, although all intervention strategies were associated with improvements in these outcomes. This trial provides additional support for combining PE with MCE, as recommended in current clinical guidelines, to promote self-management and reduce the burden of CLBP in low-resource rural communities.

Effect of integrated exercise therapy and psychosocial interventions on self-efficacy in patients with chronic low back pain: A systematic review

OBJECTIVE

Investigate if integrated exercise and psychosocial (EP) interventions effect self-efficacy to manage pain and self-efficacy for physical functioning compared to alternate interventions, usual care, waitlists and attention controls for individuals with chronic low back pain (CLBP).

METHODS

MEDLINE, Embase, CINAHL, Web of Science, PsychINFO, PEDro, and Cochrane Library were searched. Included randomized controlled trials utilized an EP intervention for CLBP and measured self-efficacy. Independent reviewers screened abstracts, reviewed full-texts, extracted data, and assessed risk of bias. GRADE, synthesis without meta-analysis, and ranges of effects (Hedges' g) were used.

RESULTS

2207 Participants were included (22-studies). EP interventions positively effected self-efficacy to manage pain short-term compared to usual care (range of effects: -0.02, 0.94) and controls (range of effects: 0.69, 0.80) and intermediately compared to usual care (range of effects: 0.11, 0.29); however, no differences were found when compared to alternate interventions. EP interventions positively effected self-efficacy for physical functioning short-term compared to alternate interventions (range of effects: 0.57, 0.71), usual care (range of effects: -0.15, 0.94), and controls (range of effects: 0.31, 0.56), and intermediately compared to alternate interventions (1-study, effect: 0.57) and controls (1-study, effect: 0.56). Conclusions were limited by low to very low-quality-evidence often from risk of bias, imprecision, and clinical/statistical heterogeneity.

CONCLUSIONS

EP interventions may be more effective short-term for self-efficacy to manage pain than usual care and waitlists, but not alternate interventions. EP interventions may be effective for self-efficacy for physical functioning at short- and intermediate-term compared to alternate interventions, usual care, waitlist and attention controls. Considerations for future research include methods for blinding and measurement of self-efficacy for physical functioning.

Education-Enhanced Conventional Care versus Conventional Care Alone for Temporomandibular Disorders: A Randomized Controlled Trial

The objective of this study was to determine the effect of enhancing conventional care for people with chronic painful temporomandibular disorders (TMD) with an individualised contemporary pain science education (PSE) intervention. In this randomized controlled trial, a consecutive sample of 148 participants (18-55 years of age) was randomized into 2 groups: PSE-enhanced conventional care or Conventional care alone. Conventional care involved a 6-week, 12-session manual therapy and exercise program. The PSE enhancement involved 2 sessions of modern PSE, undertaken in the first 2 treatment sessions. Primary outcomes were pain intensity, assessed with a numeric pain rating scale, and disability, assessed with the craniofacial pain and disability inventory, post-treatment. Linear mixed model analyses were used to investigate between-group differences over time. There was a statistically and clinically meaningful effect of PSE enhancement on disability (Mean Difference = 6.1, 95% CI: 3.3-8.8), but not on pain intensity, post-treatment. Secondary analyses suggested clinically meaningful benefit of PSE enhancement on pain and disability ratings at 10-week and 18-week follow-ups, raising the possibility that preceding conventional care with a PSE intervention may result in long-term benefits. PERSPECTIVE: The addition of modern Pain Science Education (PSE) intervention improved disability for people with chronic TMD receiving manual therapy and exercise, but not pain. A mean difference in pain and disability favoring the PSE group at the 10- and 18-week follow-ups, respectively, suggests that PSE addition resulted in longer-lasting effects.

Clarification of the "pain neuroscience education" concept in the management of patients with persistent low back pain: A scoping review

BACKGROUND

Patient education is a recommended treatment strategy for persistent low back pain (PLBP). Pain neuroscience education (PNE) is an emerging concept with boundaries still unclear.

OBJECTIVE

To clarify the PNE concept and identify its key characteristics in PLBP management.

METHODS

A systematic search was conducted using the following databases: Pubmed, ScienceDirect, Google Scholar, Cochrane, and Pedro.

INCLUSION CRITERIA

publications in English or French on pain neuroscience education and chronic low back pain, educational books cited in white literature. Three reviewers independently selected eligible studies for final inclusion. Numerical analysis and narrative synthesis were carried out from the extracted data.

RESULTS

From 919 identified publications, 54 were selected. Ten educational resources were added. PNE refers to a theoretical framework, a specific educational intervention, and an overall care approach. It is characterized by the intention to help the patient reconceptualize their PLBP from a tissue injury marker to a protective, neurobiological perspective, and then to increase adherence to biopsychosocial rehabilitation and normalize cognitive-behavioral responses. Pain sciences concepts are presented with an optimization of learning strategies.

CONCLUSION

PNE stands out from other educational and cognitive behavioral approaches through its objective of changing the pain concept.

Effectiveness of High-Intensity Laser Therapy Plus Ultrasound-Guided Peritendinous Hyaluronic Acid Compared to Therapeutic Exercise for Patients with Lateral Elbow Tendinopathy

Lateral elbow tendinopathy (LET) is a common painful musculoskeletal disorder. Several treatments have been proposed to provide pain reduction and functional recovery, including laser therapy, hyaluronic acid peritendinous injection (Hy-A), and therapeutic exercise (TE). Our study aims to assess the effectiveness of a combined approach with high-intensity laser therapy (HILT) and Hy-A injections compared to TE on pain, muscle strength, and disability in patients with painful LET. A retrospective longitudinal study was carried out by consulting the medical records of patients with a diagnosis of painful LET formulated by clinical and instrumental findings that received functional evaluations, including the Patient-Rated Tennis Elbow Evaluation (PRTEE) and muscle strength measurement at least four times: T0 (“baseline”), 1-month (T1), 3-month (T2), and 6-month follow-ups (T3). Medical records of 80 patients were analyzed. In the HILT + HyA group, the Peak-strength (p < 0.001) and mean strength (p < 0.001) significantly increased compared to the TE group between study times. For the PRTEE-total-score as for the subscales, the HILT + HyA group reported statistically significant reductions only for the comparisons of baseline versus T1 and baseline versus T2. No serious adverse events occurred. Our findings suggest that Hy-A associated with HILT might be more effective than TE for people with LET in the short−medium term.

Best Exercise Options for Reducing Pain and Disability in Adults With Chronic Low Back Pain: Pilates, Strength, Core-Based, and Mind-Body. A Network Meta-analysis

OBJECTIVE

To determine which type of exercise is best for reducing pain and disability in adults with chronic low back pain (LBP).

DESIGN

Systematic review with a network meta-analysis (NMA) of randomized controlled trials (RCTs).

LITERATURE SEARCH

Six electronic databases were systematically searched from inception to July 2021.

STUDY SELECTION CRITERIA

RCTs testing the effects of exercise on reducing self-perceived pain or disability in adults (aged 18-65 years) with chronic LBP.

DATA SYNTHESIS

We followed the PRISMA-NMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses, incorporating NMAs of health care interventions) statement when reporting our NMA. A frequentist NMA was conducted. The probability of each intervention being the most effective was conducted according to surface under the cumulative ranking curve (SUCRA) values.

RESULTS

We included 118 trials (9710 participants). There were 28 head-to-head comparisons, 7 indirect comparisons for pain, and 8 indirect comparisons for disability. Compared with control, all types of physical exercises were effective for improving pain and disability, except for stretching exercises (for reducing pain) and the McKenzie method (for reducing disability). The most effective interventions for reducing pain were Pilates, mind-body, and core-based exercises. The most effective interventions for reducing disability were Pilates, strength, and core-based exercises. On SUCRA analysis, Pilates had the highest likelihood for reducing pain (93%) and disability (98%).

CONCLUSION

Although most exercise interventions had benefits for managing pain and disability in chronic LBP, the most beneficial programs were those that included (1) at least 1 to 2 sessions per week of Pilates or strength exercises; (2) sessions of less than 60 minutes of core-based, strength, or mind-body exercises; and (3) training programs from 3 to 9 weeks of Pilates and core-based exercises.

Learning the neurobiology of pain: A scoping review of pain education from an instructional design perspective

OBJECTIVES

Learning modern pain biology concepts can improve important clinical outcomes for people with chronic pain. The primary purpose of this scoping review is to examine and report characteristics of chronic musculoskeletal pain education programs from an instructional design perspective.

METHODS

Following PRISMA-ScR guidelines, PubMed, Medline, and CINAHL databases were systematically searched. Articles included expert recommendations and those reporting pain education programs used in clinical trials enrolling adults with chronic neuromusculoskeletal pain and published in English between 1990 and 2021. Three authors independently evaluated articles for eligibility through title, abstract, and full text review. Instructional design characteristics such as learning outcomes, support materials, learning assessment methods, and key concepts communicated were summarized.

RESULTS

The search revealed 5260 articles of which 40 were included: 27 clinical studies, 7 expert recommendations, and 6 articles reporting on pain education from participant perspectives. Detailed reporting of instructional design characteristics informing replication in subsequent studies is sparse. Most included trials used only lecture and did not assess participant learning.

CONCLUSIONS

More comprehensive reporting of pain education programs is needed to facilitate replicability.

PRACTICAL IMPLICATIONS

This article proposes detailed and standardized reporting of trials using pain education programs employing a modified version of the TIDieR checklist.

Effectiveness of training physical therapists in pain neuroscience education for patients with chronic spine pain: a cluster-randomized trial

ABSTRACT

Chronic spinal pain poses complex challenges for health care around the world and is in need of effective interventions. Pain neuroscience education (PNE) is a promising intervention hypothesized to improve pain and disability by changing individuals' beliefs, perceptions, and expectations about pain. Pain neuroscience education has shown promise in small, controlled trials when implemented in tightly controlled situations. Exploration of promising interventions through more pragmatic methodologies is a crucial but understudied step towards improving outcomes in routine clinical care. The purpose was to examine the impact of pragmatic PNE training on clinical outcomes in patients with chronic spine pain. The cluster-randomized clinical trial took place in 45 outpatient physical therapist (PT) clinics. Participants included 108 physical therapists (45 clinics and 16 clusters) and 319 patients. Clusters of PT clinics were randomly assigned to either receive training in PNE or no intervention and continue with usual care (UC). We found no significant differences between groups for our primary outcome at 12 weeks, Patient-Reported Outcomes Measurement Information System Physical Function computer adaptive test {mean difference = 1.05 (95% confidence interval [CI]: -0.73 to 2.83), P = 0.25}. The PNE group demonstrated significant greater improvements in pain self-efficacy at 12 and 2 weeks compared with no intervention (mean difference = 3.65 [95% CI: 0.00-7.29], P = 0.049 and = 3.08 [95% CI: 0.07 to -6.09], P = 0.045, respectively). However, a similar percentage of participants in both control (41.1%) and treatment (44.4%) groups reported having received the treatment per fidelity question (yes or no to pain discussed as a perceived threat) at 2 weeks. Pragmatic PT PNE training and delivery failed to produce significant functional changes in patients with chronic spinal pain but did produce significant improvement in pain self-efficacy over UC PT.

Does a powerlifting inspired exercise programme better compliment pain education compared to bodyweight exercise for people with chronic low back pain? A multicentre, single-blind, randomised controlled trial

BACKGROUND

Contemporary management of chronic low back pain involves combined exercise and pain education. Currently, there is a gap in the literature for whether any exercise mode better pairs with pain education. The purpose of this study was to compare general callisthenic exercise with a powerlifting style programme, both paired with consistent pain education, for chronic low back pain. We hypothesised powerlifting style training may better compliment the messages of pain education.

METHODS

An 8-week single-blind randomised controlled trial was conducted comparing bodyweight exercise (n  =  32) with powerlifting (n  =  32) paired with the same education, for people with chronic low back pain. Exercise sessions were one-on-one and lasted 60-min, with the last 5-15 min comprising pain education. Pain, disability, fear, catastrophizing, self-efficacy, anxiety, and depression were measured at baseline, 8-weeks, 3-months, and 6-months.

RESULTS

No significant between-group differences were observed for pain (p≥0.40), or disability (p≥0.45) at any time-point. Within-group differences were significantly improved for pain (p ≤ 0.04) and disability (p ≤ 0.04) at all time-points for both groups, except 6-month disability in the bodyweight group (p  =  0.1). Behavioural measures explained 39-60% of the variance in changes in pain and disability at each time-point, with fear and self-efficacy emerging as significant in these models (p ≤ 0.001).

CONCLUSIONS

Both powerlifting and bodyweight exercise were safe and beneficial when paired with pain education for chronic low back pain, with reductions in pain and disability associated with improved fear and self-efficacy. This study provides opportunity for practitioners to no longer be constrained by systematic approaches to chronic low back pain.

Impact of contextual factors on patient outcomes following conservative low back pain treatment: systematic review

BACKGROUND AND OBJECTIVE

Chronic low back pain is pervasive, societally impactful, and current treatments only provide moderate relief. Exploring whether therapeutic elements, either unrecognised or perceived as implicit within clinical encounters, are acknowledged and deliberately targeted may improve treatment efficacy. Contextual factors (specifically, patient's and practitioner's beliefs/characteristics; patient-practitioner relationships; the therapeutic setting/environment; and treatment characteristics) could be important, but there is limited evidence regarding their influence. This research aims to review the impact of interventions modifying contextual factors during conservative care on patient's pain and physical functioning.

DATABASES AND DATA TREATMENT

Four electronic databases (Medline, CINAHL, PsycINFO and AMED) were searched from 2009 until 15th February 2022, using tailored search strategies, and resulted in 3476 unique citations. After initial screening, 170 full-text records were potentially eligible and assessed against the inclusion-exclusion criteria. Thereafter, studies were assessed for methodological quality using a modified Downs and Black scale, data extracted, and synthesised using a narrative approach.

RESULTS

Twenty-one primary studies (N = 3075 participants), were included in this review. Eight studies reported significant improvements in pain intensity, and seven in physical functioning, in favour of the contextual factor intervention(s). Notable contextual factors included: addressing maladaptive illness beliefs; verbal suggestions to influence symptom change expectations; visual or physical cues to suggest pain-relieving treatment properties; and positive communication such as empathy to enhance the therapeutic alliance.

CONCLUSION

This review identified influential contextual factors which may augment conservative chronic low back pain care. The heterogeneity of interventions suggests modifying more than one contextual factor may be more impactful on patients' clinical outcomes, although these findings require judicious interpretation.

Effects of pain neuroscience education and rehabilitation following arthroscopic rotator cuff repair. A randomized clinical trial

OBJECTIVE

To compare the effectiveness of pain neuroscience education (PNE) versus biomedical education (BME) in a rehabilitation program following arthroscopic rotator cuff repair (ARCR) in patients with chronic shoulder pain.

METHODS

Twenty-nine patients who participated in a rehabilitation program were randomly assigned to either an experimental PNE group (N = 16) or a control BME group (N = 13). Measurements included pain intensity at rest and in movement, pain catastrophizing, kinesiophobia, disability and health-related quality of life (HRQoL). Outcomes were evaluated at baseline and at 4 and 8 weeks after the intervention.

RESULTS

A main effect for time was observed for: intensity of pain at rest (p < .01); pain with movement (p < .01); pain catastrophizing (p < .01); kinesiophobia (p < .01); disability (p < .01); and HRQoL (p < .01). No group interactions were significant for any variable, except for pain with movement, which favored the PNE group (p = .03). Large effect sizes (ranging from d = 0.79 to d = 2.65) were found for both interventions in all outcomes.

CONCLUSION

A rehabilitation program including either PNE or BME are equally effective in improving rest pain, pain catastrophizing, kinesiophobia, disability, and HRQoL in patients after ARCR, except for pain at movement in favor of the PNE group. The inclusion of PNE in the rehabilitation program appears to lead to clinically meaningful improvements in pain at rest in short term when treating patients with ARCR.

Pain Science Education Plus Exercise Therapy in Chronic Nonspecific Spinal Pain: A Systematic Review and Meta-analyses of Randomized Clinical Trials

Exercise therapy and education are recommended from several guidelines for managing symptoms in chronic nonspecific spinal pain (CNSP) patients. However, no systematic reviews have previously analyzed the effectiveness of pain science education (PSE) plus exercise therapy for managing CNSP related symptoms. Systematic searches were conducted on 10 databases looking for randomized control trials (RCTs) aimed to evaluate the effectiveness on pain, disability, kinesiophobia, and catastrophizing. Data were analyzed using random-effects meta-analyses and studies were appraised using the Cochrane ROB tool and GRADE. A total of eight RCTs (n = 622) were included in the qualitative-analysis and five were selected for meta-analysis. PSE plus exercise therapy showed improvements in pain (5RCTs: short-term: SMD: -0.53 [-0.86,-0.2]; 4RCTs: intermediate-term: SMD: -0.57 [-1.01,-0.14]; low quality), disability (4RCTs: short-term: SMD: -0.24 [-0.53,0.05]; 4RCTs: intermediate-term: SMD: -0.93 [-1.08,-0.03]; low-to-very-low quality), kinesiophobia (3RCTs: short-term: SMD: -0.7 [-1.51,0.11]; 4RCTs: intermediate-term: SMD: -0.93 [-1.57,-0.30]; moderate-to-very-low quality), and catastrophizing (2RCTs: short-term: MD: -3.26 points [-6.15,-0.37]; 3RCTs: intermediate-term: MD: -4.94 points [-8.08,-1.81]; low-to-very-low quality) compared to exercise alone. A qualitative-analysis showed improvements in the experimental group compared to multimodal physiotherapy (1RCT; low-to-very-low quality), whereas no clear benefits were reported compared to PSE alone (1RCT; very-low quality) or no intervention (1RCT; very-low quality). There is low to very-low certainty of the evidence suggesting that PSE plus exercise therapy reduces CNSP related-symptoms. PERSPECTIVE: Based on low-quality data from small samples, PSE plus exercise therapy reduces CNSP related symptoms. The evidence requires further investigation due to the limited number of studies with short follow-up periods (CRD42020168968).

Physiotherapy combined with therapeutic neuroscience education versus physiotherapy alone for patients with chronic low back pain: A pilot, randomized-controlled trial

Objectives

The aim of this study was to investigate the effect of therapeutic neuroscience education (TNE) combined with physiotherapy on pain, kinesiophobia, endurance, and disability in chronic low back pain (CLBP) patients.

Patients and methods

Between November 2016 and December 2017, a total of 31 patients with CLBP (5 males, 26 females; mean age: 42.3±10.8 years; range, 20 to 58 years) were randomly allocated to receive physiotherapy combined with TNE (experimental group, EG, n=16) and physiotherapy alone (control group, CG, n=15). All participants received physiotherapy consisting of five sessions per week for a total of three weeks. In addition to physiotherapy, the EG received TNE sessions consisting of two sessions per week for a total of three weeks. The primary outcomes were pain intensity as assessed by Visual Analog Scale (VAS) and kinesiophobia by Tampa Scale for Kinesiophobia (TSK), while and the secondary outcomes were trunk muscle endurance as assessed by the partial curl-up test (trunk flexor endurance [TFE]) and modified Sorensen test (trunk extensor endurance [TEE]) and disability by Roland-Morris Disability Questionnaire (RMDQ).

Results

All patients completed the study. The median VAS, TSK, TFE, TEE, and RMDQ scores for the EG significantly improved after three weeks, while there was only significant improvement in the VAS, TSK, and RMDQ scores in the CG. The TSK decreased more in the EG than in the CG. The significant difference was evident in TSK and TFE in favor of the EG (p<0.05).

Conclusion

These results suggest that the combination of TNE with physiotherapy can improve kinesiophobia and trunk flexor muscle endurance of patients with CLBP in the short-term.

Exercise therapy for chronic low back pain

BACKGROUND

Low back pain has been the leading cause of disability globally for at least the past three decades and results in enormous direct healthcare and lost productivity costs.

OBJECTIVES

The primary objective of this systematic review is to assess the impact of exercise treatment on pain and functional limitations in adults with chronic non-specific low back pain compared to no treatment, usual care, placebo and other conservative treatments.

SEARCH METHODS

We searched CENTRAL (which includes the Cochrane Back and Neck trials register), MEDLINE, Embase, CINAHL, PsycINFO, PEDro, SPORTDiscus, and trials registries (ClinicalTrials.gov and World Health Organization International Clinical Trials Registry Platform), and conducted citation searching of relevant systematic reviews to identify additional studies. The review includes data for trials identified in searches up to 27 April 2018. All eligible trials have been identified through searches to 7 December 2020, but have not yet been extracted; these trials will be integrated in the next update.

SELECTION CRITERIA

We included randomised controlled trials that assessed exercise treatment compared to no treatment, usual care, placebo or other conservative treatment on the outcomes of pain or functional limitations for a population of adult participants with chronic non-specific low back pain of more than 12 weeks' duration.

DATA COLLECTION AND ANALYSIS

Two authors screened and assessed studies independently, with consensus. We extracted outcome data using electronic databases; pain and functional limitations outcomes were re-scaled to 0 to 100 points for meta-analyses where 0 is no pain or functional limitations. We assessed risk of bias using the Cochrane risk of bias (RoB) tool and used GRADE to evaluate the overall certainty of the evidence. When required, we contacted study authors to obtain missing data. To interpret meta-analysis results, we considered a 15-point difference in pain and a 10-point difference in functional limitations outcomes to be clinically important for the primary comparison of exercise versus no treatment, usual care or placebo.

MAIN RESULTS

We included 249 trials of exercise treatment, including studies conducted in Europe (122 studies), Asia (38 studies), North America (33 studies), and the Middle East (24 studies). Sixty-one per cent of studies (151 trials) examined the effectiveness of two or more different types of exercise treatment, and 57% (142 trials) compared exercise treatment to a non-exercise comparison treatment. Study participants had a mean age of 43.7 years and, on average, 59% of study populations were female. Most of the trials were judged to be at risk of bias, including 79% at risk of performance bias due to difficulty blinding exercise treatments. We found moderate-certainty evidence that exercise treatment is more effective for treatment of chronic low back pain compared to no treatment, usual care or placebo comparisons for pain outcomes at earliest follow-up (MD -15.2, 95% CI -18.3 to -12.2), a clinically important difference. Certainty of evidence was downgraded mainly due to heterogeneity. For the same comparison, there was moderate-certainty evidence for functional limitations outcomes (MD -6.8 (95% CI -8.3 to -5.3); this finding did not meet our prespecified threshold for minimal clinically important difference. Certainty of evidence was downgraded mainly due to some evidence of publication bias.  Compared to all other investigated conservative treatments, exercise treatment was found to have improved pain (MD -9.1, 95% CI -12.6 to -5.6) and functional limitations outcomes (MD -4.1, 95% CI -6.0 to -2.2). These effects did not meet our prespecified threshold for clinically important difference. Subgroup analysis of pain outcomes suggested that exercise treatment is probably more effective than education alone (MD -12.2, 95% CI -19.4 to -5.0) or non-exercise physical therapy (MD -10.4, 95% CI -15.2 to -5.6), but with no differences observed for manual therapy (MD 1.0, 95% CI -3.1 to 5.1). In studies that reported adverse effects (86 studies), one or more adverse effects were reported in 37 of 112 exercise groups (33%) and 12 of 42 comparison groups (29%). Twelve included studies reported measuring adverse effects in a systematic way, with a median of 0.14 (IQR 0.01 to 0.57) per participant in the exercise groups (mostly minor harms, e.g. muscle soreness), and 0.12 (IQR 0.02 to 0.32) in comparison groups.

AUTHORS' CONCLUSIONS

We found moderate-certainty evidence that exercise is probably effective for treatment of chronic low back pain compared to no treatment, usual care or placebo for pain. The observed treatment effect for the exercise compared to no treatment, usual care or placebo comparisons is small for functional limitations, not meeting our threshold for minimal clinically important difference. We also found exercise to have improved pain (low-certainty evidence) and functional limitations outcomes (moderate-certainty evidence) compared to other conservative treatments; however, these effects were small and not clinically important when considering all comparisons together. Subgroup analysis suggested that exercise treatment is probably more effective than advice or education alone, or electrotherapy, but with no differences observed for manual therapy treatments.

The EPIPHA-KNEE trial: Explaining Pain to target unhelpful pain beliefs to Increase PHysical Activity in KNEE osteoarthritis - a protocol for a multicentre, randomised controlled trial with clinical- and cost-effectiveness analysis

Background

Despite well-established benefits of physical activity for knee osteoarthritis (OA), nine of ten people with knee OA are inactive. People with knee OA who are inactive often believe that physical activity is dangerous, fearing that it will further damage their joint(s). Such unhelpful beliefs can negatively influence physical activity levels. We aim to evaluate the clinical- and cost-effectiveness of integrating physiotherapist-delivered pain science education (PSE), an evidence-based conceptual change intervention targeting unhelpful pain beliefs by increasing pain knowledge, with an individualised walking, strengthening, and general education program.

Methods

Two-arm, parallel-design, multicentre randomised controlled trial involving 198 people aged ≥50 years with painful knee OA who do not meet physical activity guideline recommendations or walk regularly for exercise. Both groups receive an individualised physiotherapist-led walking, strengthening, and OA/activity education program via 4x weekly in-person treatment sessions, followed by 4 weeks of at-home activities (weekly check-in via telehealth), with follow-up sessions at 3 months (telehealth) and 5 and 9 months (in-person). The EPIPHA-KNEE group also receives contemporary PSE about OA/pain and activity, embedded into all aspects of the intervention. Outcomes are assessed at baseline, 12 weeks, 6 and 12 months. Primary outcomes are physical activity level (step count; wrist-based accelerometry) and self-reported knee symptoms (WOMAC Total score) at 12 months. Secondary outcomes are quality of life, pain intensity, global rating of change, self-efficacy, pain catastrophising, depression, anxiety, stress, fear of movement, knee awareness, OA/activity conceptualisation, and self-regulated learning ability. Additional measures include adherence, adverse events, blinding success, COVID-19 impact on activity, intention to exercise, treatment expectancy/perceived credibility, implicit movement/environmental bias, implicit motor imagery, two-point discrimination, and pain sensitivity to activity. Cost-utility analysis of the EPIPHA-KNEE intervention will be undertaken, in addition to evaluation of cost-effectiveness in the context of primary trial outcomes.

Discussion

We will determine whether the integration of PSE into an individualised OA education, walking, and strengthening program is more effective than receiving the individualised program alone. Findings will inform the development and implementation of future delivery of PSE as part of best practice for people with knee OA.

Exploring how people with chronic pain understand their pain: a qualitative study

OBJECTIVES

A fundamental principle of pain management is educating patients on their pain using current neuroscience. However, current pain neurophysiology education (PNE) interventions show variable success in improving pain outcomes, and may be difficult to integrate with existing understanding of pain. This study aimed to investigate how people with chronic pain understand their pain, using qualitative exploration of their conceptualisations of pain, and how this understanding accommodated, or resisted, the messages of PNE.

METHODS

Twelve UK adults with chronic pain were recruited through advertisements on online pain networks. Semi-structured interviews were conducted remotely, with responses elicited using the Grid Elaboration Method (GEM) and then a PNE article. Participants' grid elaborations and responses to PNE were analysed using thematic analysis (TA).

RESULTS

Three main themes were extracted from participants' grid elaborations: communicating pain, explaining pain and living with pain. These themes incorporated varied, inconsistent sub-themes: of pain as simultaneously experiential and conceptual; in the body and in the mind; diagnosable and inexplicable; manageable and insuperable. Generalised, meta-level agreement was identified in participants' PNE responses, but with doubts about its practical value.

CONCLUSIONS

This study shows that people understand pain through inconsistent experiential models that may resist attempts at conceptual integration. Participants' elaborations showed diverse and dissonant conceptualisations, with experiential themes of restricted living; assault on the self; pursuit of understanding pain and abandonment of that pursuit. Responses, although unexpectedly compatible with PNE, suggested that PNE was perceived as intellectually engaging but practically inadequate. Experiential disconfirmation may be required for behavioural change inhibited by embedded fears and aversive experiences.

Applicability of pain neuroscience education: Where are we now?

BACKGROUND

Explaining pain to patients through pain neuroscience education (PNE) is currently a widespread treatment studied in the musculoskeletal context. Presently, there is sufficient evidence supporting the effectiveness of PNE in patients with chronic musculoskeletal disorders. However, clinicians must pay attention to the actual possibility to transfer research findings in their specific clinical context.

OBJECTIVE

We analysed the applicability of results of studies focused on PNE, which has not been done previously.

METHODS

A detailed discussion on PNE applicability is provided, starting from published randomized controlled trials that investigated the effectiveness of PNE.

RESULTS

This paper markedly points out the awareness of clinicians on the need for an accurate contextualization when choosing PNE as an intervention in clinical practice.

The effect of a pain educational video intervention upon child pain-related outcomes: A randomized controlled study

BACKGROUND

Pain neuroscience education (PNE) has received increasing research attention demonstrating beneficial effects on pain-related outcomes in adults. Conversely, studies on the effectiveness of PNE in children are scarce.

METHODS

This study investigated the effect of a pain educational video intervention on child pain-related outcomes (i.e. experienced pain intensity, pain-related fear and catastrophic worry about pain, pain threshold and pain knowledge) in healthy children undergoing an experimental pain task. Furthermore, the moderating role of children's demographic (i.e. sex and age) and psychological (i.e. baseline pain knowledge and anticipated pain intensity, pain-related fear and catastrophic worry) characteristics was examined. Participants were 89 children (M_age  = 11.85, SD = 1.78), randomly assigned to either a condition whereby they were instructed to watch a brief pain educational video (i.e. experimental group) or to a control condition whereby they did not watch any video.

RESULTS

Study findings revealed that accurate pain knowledge and pain threshold were higher amongst children in the experimental group compared to the control group. In contrast with expectations, no main effects of the video intervention were observed for experienced pain intensity, pain-related fear and catastrophic worry. Moderation analyses indicated that the video intervention contributed, in comparison with the control condition, to higher levels of pain knowledge amongst younger children only and to higher pain thresholds amongst boys only.

CONCLUSIONS

Further investigation is needed to optimize pain educational video interventions and to determine whether more beneficial outcomes can be found in clinical (i.e. non-experimental) situations and in children with persistent or recurring pain problems.

SIGNIFICANCE

Examining the impact of pain educational interventions within a non-clinical setting is deemed particularly important given that adaptive pain coping strategies likely play an important role in preventing the development and maintenance of future maladaptive pain-related behaviour. Further, study findings provide preliminary evidence of baseline and demographic (i.e. age and sex) characteristics explaining differences in the effect of a pain educational video intervention in pain knowledge and pain-related experiences during experimental pain.

Knowledge and attitudes toward musculoskeletal pain neuroscience of manual therapy postgraduate students in the Netherlands

BACKGROUND

Health care practitioners' knowledge and attitudes influence patients' beliefs and health outcomes in musculoskeletal (MSK) pain. It is unclear to what extent physiotherapists undertaking a postgraduate master in manual therapy (MT students) possess the knowledge and attitudes toward pain neuroscience to be able to apply the biopsychosocial model in patients with MSK pain.

OBJECTIVES

The aim of this study was to assess the knowledge and attitudes toward pain neuroscience in MT students.

DESIGN

A cross-sectional study.

METHOD

Self-reported knowledge and attitudes were measured among students (n = 662) at baseline and in all years of the MT postgraduate programs in the Netherlands. The Knowledge and Attitudes of Pain questionnaire (KNAP) was used as a primary measure. Difference in KNAP-scores between baseline (0), year 1, year 2 and year 3 was tested using a one-way ANOVA (hypothesis: 0 < 1<2 < 3). A two factor ANOVA was used to determine the interaction effect of focused pain education and year in the curriculum with KNAP.

RESULTS

There was an overall significant difference of KNAP scores with a medium effect size (F(3, 218.18) = 13.56, p < .001, ω² = 0.059). Differences between years ranged from small to medium. Interaction effect of knowledge and attitudes and focused pain education was significant with a small effect size (F(6) = 2.597, p = .017, ω² = 0.012). Sensitivity analyses were consistent with the main results.

CONCLUSIONS

Positive differences in knowledge and attitudes toward pain neuroscience in MT students occur between the progressing years of the curriculum. Differences may be related to the provision of focused pain education.

A Meta-Analysis of Group-Based Pain Management Programs: Overall Effect on Quality of Life and Other Chronic Pain Outcome Measures, with an Exploration into Moderator Variables that Influence the Efficacy of Such Interventions

OBJECTIVES

Group-based pain management programs (GPMPs) have been found to significantly improve quality of life and other pain outcome measures in patients with chronic musculoskeletal pain. The aims of this meta-analysis were to reevaluate the overall effect of GPMPs on various pain outcomes for individuals experiencing chronic musculoskeletal conditions and to explore moderator variables that potentially contribute to the overall efficacy of GPMPs.

METHODS

Using the R package called metaphor and RevMan, we estimated the overall effectiveness of GPMPs on various pain outcome measures. The differential effectiveness of GPMPs was examined by conducting a mixed-effects meta-analytic model using various study-level characteristics. Moderator analyses included three content moderator variables and seven format moderator variables. Receiver operating characteristic curves investigated optimal points in some of the moderator variable analysis results.

RESULTS

Significant overall main effects of GPMPs were found on all the explored outcome measures in this study (P < 0.05). In moderator analyses, it was found that the structure of GPMPs, rather than the content, significantly improved outcomes (P < 0.05). Receiver operating characteristic curve analyses identified the optimal number of GPMP sessions and number of participants per group.

DISCUSSION AND CLINICAL RELEVANCE

GPMPs have a statistically significant overall effect on all explored pain outcome measures. The investigation into content and structural moderators suggests that certain GPMP design factors have a greater effect on pain outcomes than do content factors. Therefore, GPMP structural designs appear to be important in reducing pain and improving quality of life for patients with chronic pain and warrant further investigation.

Does pain neuroscience education improve pain knowledge, beliefs and attitudes in undergraduate physiotherapy students?

BACKGROUND

To evaluate the effect of a brief pain neuroscience education (PNE) session on physiotherapy students' knowledge of pain and their beliefs and attitudes about the treatment of patients with chronic low back pain.

METHODS

This study was a single-center, cross-sectional study including 205 physiotherapy undergraduate students. The participants completed the Neurophysiology of Pain Questionnaire (NPQ) and Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT). They then received a 70-min neuroscience education session covering the mechanisms and biopsychosocial aspects of chronic low back pain. The questionnaires were readministered immediately after the educational session and at 6 months posteducation.

RESULTS

Our analysis included data from 156 participants (mean age: 20.9 ± 2.51, 69.8% women) who completed the questionnaires pre-, post-, and 6 months after the educational session. To assess the effect of the education on the scores of the questionnaires, a repeated-measures ANOVA was conducted. There was a significant interaction observed for NPQ over time (p = 0.00; η ²  = 0.654), for PABS-PT factor 1(p < 0.001; η2 = 0.50) and for PABS-PT factor 2 over time (p = 0.02; η ²  = 0.04) CONCLUSION: This study showed that a 70-min session of PNE improves the level of pain knowledge in undergraduate physiotherapy students and influences their beliefs and attitudes concerning chronic low back pain. These findings suggest that adding PNE to the curricula of physiotherapy and rehabilitation programs may be beneficial.

Comparing the effectiveness of group-based exercise to other non-pharmacological interventions for chronic low back pain: A systematic review

Background

Low back pain (LBP) is the leading cause of disability worldwide with a substantial financial burden on individuals and health care systems. To address this, clinical practice guidelines often recommend non-pharmacological, non-invasive management approaches. One management approach that has been recommended and widely implemented for chronic LBP is group-based exercise programs, however, their clinical value compared with other non-pharmacological interventions has not been investigated systematically.

Objective

To compare the effectiveness of group-based exercise with other non-pharmacological interventions in people with chronic LBP.

Methods

Four electronic databases were searched by two independent reviewers. Only randomized controlled trials that compared group-based exercise with other non-pharmacological interventions for chronic LBP were eligible. Study quality was assessed using the Cochrane Handbook for systematic reviews of Interventions by two independent reviewers.

Results

Eleven studies were eligible. We identified strong evidence of no difference between group exercise and other non-pharmacologic interventions for disability level and pain scores 3-month post-intervention in people with chronic LBP. We could not find any strong or moderate evidence for or against the use of group-based exercise in the rehabilitation of people with chronic LBP for other time-points and health measurement outcomes. We found no statistically significant differences in disability and quality of life and pain between the group and individual non-pharmacological interventions that included exercise.

Conclusion

With this equivocal finding, group-based exercise may be a preferred choice given potential advantages in other domains not reviewed here such as motivation and cost. Further research in this area is needed to evaluate this possibility.

Assessing future health care practitioners' knowledge and attitudes of musculoskeletal pain; development and measurement properties of a new questionnaire

BACKGROUND

Healthcare practitioner beliefs influence patients' beliefs and health outcomes in musculoskeletal (MSK) pain. A validated questionnaire based on modern pain neuroscience assessing Knowledge and Attitudes of Pain (KNAP) was unavailable.

OBJECTIVES

The aim of this study was to develop and test measurement properties of KNAP.

DESIGN

Phase 1; Development of KNAP reflecting modern pain neuroscience and expert opinion. Phase 2; a cross-sectional and longitudinal study among Dutch physiotherapy students.

METHOD

In the cross-sectional study (n = 424), internal consistency, structural validity, hypotheses testing, and Rasch analysis were examined. Longitudinal designs were applied to analyse test-retest reliability (n = 156), responsiveness, and interpretability (n = 76).

RESULTS

A 30-item KNAP was developed in 4 stages. Test-retest reliability: ICC (2,1) 0.80. Internal consistency: Cronbach's α 0.80. Smallest Detectable Difference 90%: 4.99 (4.31; 5.75). Structural validity: exploratory factor analysis showed 2 factors. Hypotheses testing: associations with the Pain Attitudes and Beliefs Scale for Physiotherapists biopsychosocial subscale r = 0.60, with biomedical subscale r = -0.58, with the Neurophysiology of Pain Questionnaire r = 0.52. Responsiveness: 93% improved on KNAP after studying pain education. Minimal Important Change: 4.84 (95%CI: 2.77; 6.91).

CONCLUSIONS

The KNAP has adequate measurement properties. This new questionnaire could be useful to evaluate physiotherapy students' knowledge and attitudes of modern pain neuroscience that could help to create awareness and evaluate physiotherapy education programs, and ultimately provide better pain management.

Clinical Reasoning for the Examination and Physical Therapy Treatment of Temporomandibular Disorders (TMD): A Narrative Literature Review

The current narrative literature review aims to discuss clinical reasoning based on nociceptive pain mechanisms for determining the most appropriate assessment and therapeutic strategy and to identify/map the most updated scientific evidence in relation to physical therapy interventions for patients with temporomandibular disorders (TMDs). We will also propose an algorithm for clinical examination and treatment decisions and a pain model integrating current knowledge of pain neuroscience. The clinical examination of patients with TMDs should be based on nociceptive mechanisms and include the potential identification of the dominant, central, or peripheral sensitization driver. Additionally, the musculoskeletal drivers of these sensitization processes should be assessed with the aim of reproducing symptoms. Therapeutic strategies applied for managing TMDs can be grouped into tissue-based impairment treatments (bottom-up interventions) and strategies targeting the central nervous system (top-down interventions). Bottom-up strategies include joint-, soft tissue-, and nerve-targeting interventions, as well as needling therapies, whereas top-down strategies include exercises, grade motor imagery, and also pain neuroscience education. Evidence shows that the effectiveness of these interventions depends on the clinical reasoning applied, since not all strategies are equally effective for the different TMD subgroups. In fact, the presence or absence of a central sensitization driver could lead to different treatment outcomes. It seems that multimodal approaches are more effective and should be applied in patients with TMDs. The current paper also proposes a clinical decision algorithm integrating clinical diagnosis with nociceptive mechanisms for the application of the most appropriate treatment approach.

Relationship between low back pain and lumbar and hip joint movement in desk workers

[Purpose] The study aimed to determine the relationship between low back pain and lumbar and hip movement in desk workers with chronic non-specific low back pain, in order to obtain basic data regarding measures for preventing low back pain in desk workers. [Participants and Methods] The study included 10 desk workers (all female, age: 47.1 ± 6.0 years). The following measurements were recorded: numerical rating scale score for pain assessment at the time of maximum forward and backward bending of the trunk while standing, and the amount of movement of the trunk and the lumbar and hip joint. The ratio of the lumbar and hip joint movements during maximum forward and backward bending of the trunk was calculated. [Results] For maximum forward and backward bending of the trunk, a positive correlation between the numerical rating scale score and the ratio of movement for the lumbar and a negative correlation with that of the hip joint were noted. [Conclusion] Moving the hip joint while suppressing excessive lumbar movement is one of the measures for preventing low back pain in desk workers.

A Meta-Analysis of Therapeutic Pain Neuroscience Education, Using Dosage and Treatment Format as Moderator Variables

OBJECTIVES

This meta-analysis aimed to assess the overall effect of therapeutic pain neuroscience education (TPNE) on chronic musculoskeletal pain and to further assess whether such an effect differs by TPNE dosage as well as other treatment format components. Dosage included the number of TPNE sessions provided as well as the amount of time per TPNE session. Structural components included TPNE provided alone as treatment or combined with other pain management modalities, as well as the inclusion of group-based treatment sessions.

METHODS

Electronic databases were utilized to search for randomized controlled trials that included TPNE. The overall effectiveness of TPNE was estimated on 4 pain outcome measures, including kinesiophobia, pain intensity, pain disability, and pain catastrophizing. The differential effectiveness of TPNE was examined using a mixed-methods moderator analysis on various study-level characteristics to identify potential moderators affecting the overall results.

RESULTS

Significant effects of TPNE were found on all the outcome measures. The only moderator that displayed a significant effect was group-based treatment on kinesiophobia (z = -2.23, P < 0.05, 95% confidence interval [CI] -2.70 to -0.20). Between-group analysis revealed that only interventions that included group sessions were found to be statistically significant (z = 2.20, P < 0.05) and displayed a large effect size (d = 0.80, 95% CI 0.09 to 1.50).

DISCUSSION

Therapeutic pain neuroscience education had a statistically significant impact on all the explored pain outcome measures. However, when investigating the treatment dosage and format moderator variables, they appeared to not have a statistically significant effect except for group-based interventions on kinesiophobia levels.

CONCLUSION

This meta-analysis examined the efficacy of TPNE for patients with chronic pain. It assessed various pain outcome measures following intervention. In addition, this research identified that various moderator variables do not have and do have an impact on the treatment modality of TPNE.

Effectiveness of communicative and educative strategies in chronic low back pain patients: A systematic review

OBJECTIVE

To investigate the effectiveness of communicative and educative strategies on 1) patient's low back pain awareness/knowledge, 2) maladaptive behavior modification and 3) compliance with exercise in patients with chronic low back pain.

METHODS

A systematic review was conducted. Searches were performed on 13 databases. Only randomized controlled trials enrolling patients ≥ 18 years of age were included. Risk of bias was assessed with the Cochrane Collaboration's tool and interrater agreement between authors for full-texts selection was evaluated with Cohen's Kappa. No meta-analysis was performed and qualitative analysis was conducted.

RESULTS

24 randomized controlled trials which intervention included communicative and educative strategies were selected. Most of the studies were judged as low risk of bias and Cohen's Kappa was excellent ( = 0.822). Interventions addressed were cognitive behavioral therapy as unique treatment or combined with other treatments (multimodal interventions), coaching, mindfulness, pain science education, self-management, graded activity and graded exposure.

CONCLUSIONS, PRACTICE IMPLICATION

Patient's low back pain awareness/knowledge is still a grey area of literature. Pain science education, graded exposure and multimodal interventions are the most effective for behavior modification and compliance with exercise with benefits also in the long-term, while self-management, graded activity and coaching provide only short-term or no benefits.

Exercise treatment effect modifiers in persistent low back pain: an individual participant data meta-analysis of 3514 participants from 27 randomised controlled trials

Background

Low back pain is one of the leading causes of disability worldwide. Exercise therapy is widely recommended to treat persistent non-specific low back pain. While evidence suggests exercise is, on average, moderately effective, there remains uncertainty about which individuals might benefit the most from exercise.

Methods

In parallel with a Cochrane review update, we requested individual participant data (IPD) from high-quality randomised clinical trials of adults with our two primary outcomes of interest, pain and functional limitations, and calculated global recovery. We compiled a master data set including baseline participant characteristics, exercise and comparison characteristics, and outcomes at short-term, moderate-term and long-term follow-up. We conducted descriptive analyses and one-stage IPD meta-analysis using multilevel mixed-effects regression of the overall treatment effect and prespecified potential treatment effect modifiers.

Results

We received IPD for 27 trials (3514 participants). For studies included in this analysis, compared with no treatment/usual care, exercise therapy on average reduced pain (mean effect/100 (95% CI) −10.7 (−14.1 to –7.4)), a result compatible with a clinically important 20% smallest worthwhile effect. Exercise therapy reduced functional limitations with a clinically important 23% improvement (mean effect/100 (95% CI) −10.2 (−13.2 to –7.3)) at short-term follow-up. Not having heavy physical demands at work and medication use for low back pain were potential treatment effect modifiers—these were associated with superior exercise outcomes relative to non-exercise comparisons. Lower body mass index was also associated with better outcomes in exercise compared with no treatment/usual care. This study was limited by inconsistent availability and measurement of participant characteristics.

Conclusions

This study provides potentially useful information to help treat patients and design future studies of exercise interventions that are better matched to specific subgroups.

Domains of Chronic Low Back Pain and Assessing Treatment Effectiveness: A Clinical Perspective

Nonspecific chronic low back pain (CLBP) is a common clinical condition that has impacts at both the individual and societal level. Pain intensity is a primary outcome used in clinical practice to quantify the severity of CLBP and the efficacy of its treatment; however, pain is a subjective experience that is impacted by a multitude of factors. Moreover, differences in effect sizes for pain intensity are not observed between common conservative treatments, such as spinal manipulative therapy, cognitive behavioral therapy, acupuncture, and exercise training. As pain science evolves, the biopsychosocial model is gaining interest in its application for CLBP management. The aim of this article is to discuss our current scientific understanding of pain and present why additional factors should be considered in conservative CLBP management. In addition to pain intensity, we recommend that clinicians should consider assessing the multidimensional nature of CLBP by including physical (disability, muscular strength and endurance, performance in activities of daily living, and body composition), psychological (kinesiophobia, fear-avoidance, pain catastrophizing, pain self-efficacy, depression, anxiety, and sleep quality), social (social functioning and work absenteeism), and health-related quality-of-life measures, depending on what is deemed relevant for each individual. This review also provides practical recommendations to clinicians for the assessment of outcomes beyond pain intensity, including information on how large a change must be for it to be considered "real" in an individual patient. This information can guide treatment selection when working with an individual with CLBP.

Neurophysiological Pain Education for Patients With Chronic Low Back Pain: A Systematic Review and Meta-Analysis

OBJECTIVE

To evaluate the effect of neurophysiological pain education (NPE) for patients with chronic low back pain (CLBP).

METHODS

A systematic search was performed in 6 electronic databases. Eligible randomized-controlled trials were those with at least 50 % of patients with CLBP and in which NPE was compared with no intervention or usual care. Methodological quality was assessed independently by 2 of the authors using the Cochrane Collaboration Risk of Bias Tool. The effect of NPE was summarized in a random effect meta-analysis for pain, disability, and behavioral attitudes. Effect was estimated as weighted mean difference (WMD) if outcomes were on the same scale or as standardized mean difference (SMD). The overall quality of evidence was evaluated according to GRADE guidelines.

RESULTS

Seven randomized-controlled trial studies (6 low and 1 high quality) were included. Statistically significant differences in pain, in favor of NPE, were found after treatment, WMD=-1.03 (95% confidence interval [CI], -0.55 to -1.52), and after 3 months, WMD=-1.09 (95% CI, -2.17 to 0.00). Furthermore statistically significant lower disability was found in the NPE group after treatment, SMD=-0.47 (95% CI, -0.80 to -0.13) and after 3 months SMD=-0.38 (95% CI, -0.74 to -0.02). The difference in favor of NPE in reduction in Tampa Scale of Kinesiophobia was not statistically significant, WMD=-5.73 (95% CI, -13.60 to 2.14) and after 3 months WMD=-0.94 (95% CI, -6.28 to 4.40).

DISCUSSION

There was moderate evidence supporting the hypothesis that NPE has a small to moderate effect on pain and low evidence of a small to moderate effect on disability immediately after the intervention. NPE has a small to moderate effect on pain and disability at 3 months follow-up in patients with CLBP.

Multi-disciplinary interventions for chronic pain involving education: A systematic review

BACKGROUND

There have been growing recommendations to include education in multi-disciplinary interventions targeting chronic pain management. However, effects of this strategy on short- and long-term self-management of chronic pain, remain largely unexplored.

OBJECTIVES

1. To provide an updated overview of studies that report on the impact of patient education in multi-disciplinary interventions, on self-management of chronic pain; 2. To explore associations between education and chronic pain self-management techniques; and 3. To identify the format and duration of suitable chronic pain interventions targeted at patient self-management.

METHODS

Design: Narrative systematic literature review of randomised or controlled study designs. Data Sources: PubMed, CINAHL, EMBASE, PsycINFO. Participants: Adult patients with chronic pain of any aetiology participating in multi-disciplinary programs that included education. Main outcome measures: Assessments of level of pain, function, quality of life, self-efficacy, self-management, and any other relevant assessments. Study Appraisal and Synthesis Methods: PRISMA guidelines, Cochrane Risk of Bias tool, and TIDieR model.

RESULTS

Database searching identified 485 potential papers. After removal of duplicates, and irrelevant articles by title and abstract, 120 full-text articles were reviewed and 27 studies were included in this systematic review. Studies were predominantly from the United States (n = 8; 29.6%). Over one hundred outcome measures were identified across all studies, with significant variation also observed in terms of how chronic pain duration was defined, and how education was delivered to participants. Overall, positive benefits of education were reported.

CONCLUSIONS

Education, as part of multi-disciplinary programs, is likely to improve self-management and self-efficacy in people with chronic pain of any aetiology. Heterogeneity in terms of: chronic pain duration; educational resources; healthcare professionals; and outcome measures, were identified as limitations. Further research, in the form of Randomised Controlled Trials addressing these limitations, is recommended.

A Modern Pain Neuroscience Approach in Patients Undergoing Surgery for Lumbar Radiculopathy: A Clinical Perspective

Around 20% of patients undergoing surgery for lumbar radiculopathy develop chronic pain after surgery, leading to high socioeconomic burden. Current perioperative interventions, including education and rehabilitation, are not always effective in preventing prolonged or chronic postoperative pain and disability. Here, a shift in educational intervention from a biomedical towards a biopsychosocial approach for people scheduled for lumbar surgery is proposed. Pain neuroscience education (PNE) is a biopsychosocial approach that aims to decrease the threat value of pain by reconceptualizing pain and increasing the patient's knowledge about pain. This paper provides a clinical perspective for the provision of perioperative PNE, specifically developed for patients undergoing surgery for lumbar radiculopathy. Besides the general goals of PNE, perioperative PNE aims to prepare the patient for postsurgical pain and how to cope with it.
