Effectiveness of Pain Neuroscience Education in Patients with Fibromyalgia: A Systematic Review and Meta-Analysis

Short- and medium-term effects of a single session of pain neuroscience education on pain and psychological factors in patients with chronic low back pain. A single-blind randomized clinical trial

INTRODUCTION

Biopsychosocial approach in patients suffering chronic low back pain (CLBP) promotes pain self-management strategies. Current evidence recommends high dose of Pain Neuroscience Education (PNE) for clinically significant differences. However, the workload and time constraints experienced by healthcare providers impede the application of the recommended treatment regimen. In fact, Back School with a biomechanical model is the main approach to manage CLBP in public systems.

OBJECTIVE

The objective of this study is to explore the effect of a 60 min single session of PNE as an adjunct to back school on pain intensity and psychological variables patients with CLBP.

METHODS

A double-blind, two-arm randomized controlled clinical trial was conducted in patients with CLBP who attended back school sessions held in a Spanish public hospital. A total of 121 patients were randomized into control group, who received the Back School program during 5 weeks, and intervention group, who additionally received a single session of PNE. Patient-reported outcomes were the Numerical Pain Rating Scale, Central Sensitization Inventory, Pain Catastrophizing Scale, and Tampa Scale of Kinesiophobia, with a 12-week follow-up.

RESULTS

A total of 113 patients were analysed. Intervention and control group presented similar effects on pain and kinesiophobia. At follow-up, intervention group exhibited reduced sensitization and catastrophism scores compared with control, including the subscales. Additionally, PNE reduced the percentage of participants classified as having central sensitization compared with control.

CONCLUSIONS

Adding a single PNE session in the back school program did not reduce pain but improved psychological factors as central sensitization and pain catastrophizing at medium-term. This study highlights the potential of PNE to optimize treatment strategies for CLBP, especially in public health centres where time resources are scarce.

SIGNIFICANCE STATEMENT

Adding a single PNE session in the back school program did not reduce pain but improved psychological factors as central sensitization and pain catastrophism at medium-term.

Teaching Patients About Pain: The Emergence of Pain Science Education, its Learning Frameworks and Delivery Strategies

Since it emerged in the early 2000's, intensive education about 'how pain works', widely known as pain neuroscience education or explaining pain, has evolved into a new educational approach, with new content and new strategies. The substantial differences from the original have led the PETAL collaboration to call the current iteration 'Pain Science Education'. This review presents a brief historical context for Pain Science Education, the clinical trials, consumer perspective, and real-world clinical data that have pushed the field to update both content and method. We describe the key role of educational psychology in driving this change, the central role of constructivism, and the constructivist learning frameworks around which Pain Science Education is now planned and delivered. We integrate terminology and concepts from the learning frameworks currently being used across the PETAL collaboration in both research and practice-the Interactive, Constructive, Active, Passive framework, transformative learning theory, and dynamic model of conceptual change. We then discuss strategies that are being used to enhance learning within clinical encounters, which focus on the skill, will, and thrill of learning. Finally, we provide practical examples of these strategies so as to assist the reader to drive their own patient pain education offerings towards more effective learning. PERSPECTIVE: Rapid progress in several fields and research groups has led to the emergence 'Pain Science Education'. This PETAL review describes challenges that have spurred the field forward, the learning frameworks and educational strategies that are addressing those challenges, and some easy wins to implement and mistakes to avoid.

Effect of physical activity education on shoulder girdle pain and muscle strength in participants with fibromyalgia: a pilot experimental study

Background

In patients with fibromyalgia, exercise and education are recommended to decrease pain level and improve pain management. The latest scientific evidence recommends to focus interventions on the upper limb. The aim of this pilot study was to compare the immediate effect of physical activity education vs. a control group on pain and muscle capacity in fibromyalgia patients.

Method

Fifty-six participants with fibromyalgia were randomized into an experimental group and a control group. The intervention consisted in watching a five-minute video that provided information about fibromyalgia, pain, kinesiophobia and physical activity. The control group watched a neutral five-minute video about beavers in Quebec. Following the video, participants performed a muscular fatigue task consisting of a repeated unilateral shoulder abduction task. At baseline and following the muscular fatigue task, maximal voluntary contraction (MVC) in shoulder abduction was assessed as well as pain level and pressure pain threshold (PPT) in the upper limb. Electromyographic activity was also assessed for upper trapezius and middle deltoid muscles. Two-way repeated measures analysis of variance was used to compare the MVC, PPT, and pain level before and after the muscular fatigue task between groups.

Results

The experimental group showed a significantly lower increase in pain than the control group in the middle deltoid muscle (p = 0.002) when assessed by verbal pain rating scale. No significant interaction or main effect of Group and Time were observed for the pain level at the upper trapezius and elbow extensor muscles nor for any of the PPT measures. According to electromyographic data, the median frequency values indicate that neither group experienced muscle fatigue during the repeated contraction task.

Conclusions

The preliminary results suggest that a short physical activity education video positively influenced middle deltoid pain following repeated abduction in participants with fibromyalgia. Electromyographic analysis showed no evidence of objective muscle fatigue, suggesting that there might be a partial disconnection between the perception of muscle fatigue and the physiological biomarkers associated with muscle fatigue.

Tackling Kinesiophobia in Chronic Shoulder Pain: A Case Report on the Combined Effect of Pain Education and Whole-Body Cryostimulation

BACKGROUND

Chronic shoulder pain may cause significant functional disability and reduced psychosocial well-being. Detailed Case Description: In this case, we propose the use of pain neuroscience education and whole-body cryostimulation (WBC) to treat a 64-year-old woman with severe functional limitations and chronic right shoulder pain. The aim was to overcome kinesiophobia and improve her motor function, autonomy, and quality of life. Functional and clinical assessments were conducted at admission, discharge, and at a one-month follow-up via phone call. The patient's global health, shoulder function, and quality of life showed improvement during hospitalisation and were maintained after one month.

DISCUSSION

Pain education is crucial in managing chronic shoulder pain, especially in addressing kinesiophobia and promoting positive patient outcomes. In this context, WBC was used as a supplementary treatment to traditional pain relief and exercise tolerance therapies. This can help individuals to participate more actively in their rehabilitation process, ultimately promoting functional recovery and an improved quality of life.

CONCLUSION

The combination of cryostimulation, tailored physical exercises, pain education, manual therapy, and psychological support created a synergistic effect that addressed both the physical and psychological aspects of pain and kinesiophobia.

Pain neuroscience education improves quality of life when added to aquatic exercise therapy for women with fibromyalgia: randomized controlled clinical trial

PURPOSE

The aim of the present study was to investigate the effects of adding Pain Neuroscience Education (PNE) to an aquatic therapy protocol on pain, fibromyalgia (FMS) impact, quality of life and sleep.

MATERIALS AND METHODS

Seventy-five women were randomly allocated into two groups: aquatic exercises (AEG, n = 36) and aquatic exercises + PNE (PNG, n = 39). The primary outcome was pain, and the secondary outcomes were FMS impact, quality of life, sleep and pain sensitivity (pressure pain thresholds - PPTs). Participants performed 45-min sessions of aquatic exercises, twice a week, for 12 weeks. PNG also received 4 PNE sessions during this period. Participants were assessed four times: initial (before treatment), after 6 weeks (intermediate) and 12 weeks (final) of treatment and after 12 weeks after the end of treatment (follow-up).

RESULTS

Both groups improved pain after treatment, with no difference between them (p > 0.05, partial ƞ2 0.10). FMS impact and PPTs improved after treatment with no difference between groups, and sleep did not change. Quality of life improved several domains for both groups, with slightly better results for the PNG, with low effect sizes between groups.

CONCLUSIONS

The present results show that the addition of PNE to an aquatic exercise intervention did not provide larger effects than aquatic exercises alone for people with FMS concerning pain intensity, but provided benefit for health-related quality of life for this population.

TRIAL REGISTRATION

ClinicalTrials.gov (NCT03073642, version 2, April 1st, 2019).

PERSPECTIVE

The addition of 4 Pain Neuroscience Education sessions to an aquatic exercises protocol did not add benefits for women with fibromyalgia syndrome on pain, fibromyalgia impact, and sleep, but improved quality of life and pain sensitivity.IMPLICATIONS FOR REHABILITATIONAquatic exercises are commonly prescribed, but patient education is crucial for the treatment.The addition of Pain Neuroscience Education to an aquatic exercises protocol did not add benefits for women with fibromyalgia syndrome.The positive changes on quality of life and pain sensitivity that this combination led to had small effect sizes and did not achieve minimal important clinical difference.

Neurophysiological pain education for patients with symptomatic knee osteoarthritis: A systematic review and meta-analysis

OBJECTIVE

To evaluate the effectiveness of neurophysiological pain education in patients with symptomatic knee osteoarthritis considering pain-related variables.

METHODS

A systematic review and meta-analysis was carried out according to the PRISMA guidelines. A search was conducted in PubMed, PEDro Database, Cochrane Library, Scopus, and Web of Science. Only randomized controlled trials enrolling patients ≥ 18 years of age with symptomatic knee osteoarthritis were included. The Downs and Black quality assessment tool was used to assess the quality of the articles, and the risk of bias was evaluated with the Cochrane Risk of Bias Assessment Tool.

RESULTS

A total of 7 studies were included in the study. Most of the studies were rated as "fair" on the Downs and Black quality assessment tool, and in the category of "some concerns" according to the Cochrane Risk of Bias Assessment Tool. Neurophysiological pain education was conducted alone or combined with exercise, joint mobilizations, or self-management programs. The number of sessions ranged from 1 to 10. The meta-analysis results showed significant differences in favor of the intervention group in pain (MD = -0.49; 95% CI = -0.66; -0.32; p < 0.001) and catastrophization (MD = -1.81; 95% CI = -3.31, -0.3; p = 0.02).

CONCLUSION, PRACTICE IMPLICATIONS

Neurophysiological pain education interventions in isolation or combined with exercise, joint mobilizations, or self-management programs have proven to significantly improve pain and catastrophization in patients with symptomatic knee osteoarthritis. These findings could provide clinicians with more information regarding the management of patients with symptomatic knee osteoarthritis.

Effectiveness of patient education as a stand-alone intervention for patients with chronic widespread pain and fibromyalgia: a systematic review and meta-analysis of randomized trials

OBJECTIVE

Patient education is recommended as an integral component of the therapeutic plan for the management of chronic widespread pain (CWP) and fibromyalgia (FM). The key purpose of patient education is to increase the patient's competence to manage his or her own health requirements, encouraging self-management and a return to desired everyday activities and lifestyle. The aim of this systematic review was to evaluate the evidence for the benefits and potential harms associated with the use of patient education as a stand-alone intervention for individuals with CWP and FM through randomized controlled trials (RCTs).

METHOD

On 24 November 2021 a systematic search of PubMed, MEDLINE, Embase, CENTRAL, PsycINFO, CINAHL, ClinicalTrials.gov, American College of Rheumatology, European League Against Rheumatism, and the World Health Organization International Clinical Trials Registry Platform identified 2069 studies. After full-text screening, five RCT studies were found to be eligible for the qualitative evidence synthesis.

RESULTS

Patient education as a stand-alone intervention presented an improvement in patients' global assessment (standardized mean difference 0.79, 95% confidence interval 0.13 to 1.46). When comparing patient education with usual care, no intervention, or waiting list, no differences were found for functioning, level of pain, emotional distress in regard to anxiety and depression, or pain cognition.

CONCLUSION

This review reveals the need for RCTs investigating patient education as a stand-alone intervention for patients with FM, measuring outcomes such as disease acceptance, health-related quality of life, enhancement of patients' knowledge of pain, pain coping skills, and evaluation of prioritized learning outcomes.

Exercise-based interventions on sleep quality in patients with fibromyalgia syndrome: An umbrella and mapping review with meta-analysis

The main aim of this umbrella review was to assess the impact of exercise-based interventions (EBIs) on sleep quality in patients with fibromyalgia syndrome (FMS). We searched systematically in PubMed, PEDro, EMBASE, CINAHL, SPORTDiscus and Google Scholar. Methodological quality was analyzed using AMSTAR and ROBIS scale, and the strength of evidence was established according to GRADE. Nine systematic reviews were included. Meta-analysis (MA) of primary studies (n = 42) were performed with a random-effects model. The MA revealed a moderate statistically significant effect of EBIs (SMD=-0.46 [-0.69 to -0.23]). Subgroup analyses by type of exercise showed significant effect of body-mind exercises (SMD=-0.55 [-0.86 to -0.23]) and combined exercises (SMD=-1.11 [-2.12 to -0.11]) but not for aerobic (SMD=-0.04 [-0.15 to 0.07]) or strength (SMD=-0.52 [-1.14 to 0.1]) exercises in isolation. The results obtained showed that EBIs were effective in improving sleep quality compared to minimal intervention, no intervention or usual care, with a low certainty of evidence. Subgroup analyses showed that mind-body and combined exercises elicited the strongest effect, while aerobic and strength exercise in isolation did not show significant effects.

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.
