Pain Neuroscience Education in cancer survivors with persistent pain: A pilot study

Support for Chronic Pain Management for Breast Cancer Survivors Through Novel Digital Health Ecosystems: Pilot Usability Study of the PainRELife Mobile App

BACKGROUND

Chronic pain is one of the most common and critical long-term effects of breast cancer. Digital health technologies enhance the management of chronic pain by monitoring physical and psychological health status and supporting pain self-management and patient treatment decisions throughout the clinical pathway.

OBJECTIVE

This pilot study aims to evaluate patients' experiences, including usability, with a novel digital integrated health ecosystem for chronic pain named PainRELife. The sample included patients with breast cancer during survivorship. The PainRELife ecosystem comprises a cloud technology platform interconnected with electronic health records and patients' devices to gather integrated health care data.

METHODS

We enrolled 25 patients with breast cancer (mean age 47.12 years) experiencing pain. They were instructed to use the PainRELife mobile app for 3 months consecutively. The Mobile Application Rating Scale (MARS) was used to evaluate usability. Furthermore, pain self-efficacy and participation in treatment decisions were evaluated. The study received ethical approval (R1597/21-IEO 1701) from the Ethical Committee of the European Institute of Oncology.

RESULTS

The MARS subscale scores were medium to high (range: 3.31-4.18), and the total app quality score was 3.90. Patients with breast cancer reported reduced pain intensity at 3 months, from a mean of 5 at T0 to a mean of 3.72 at T2 (P=.04). The total number of times the app was accessed was positively correlated with pain intensity at 3 months (P=.03). The engagement (P=.03), information (P=.04), and subjective quality (P=.007) subscales were positively correlated with shared decision-making. Furthermore, participants with a lower pain self-efficacy at T2 (mean 40.83) used the mobile app more than participants with a higher pain self-efficacy (mean 48.46; P=.057).

CONCLUSIONS

The data collected in this study highlight that digital health technologies, when developed using a patient-driven approach, might be valuable tools for increasing participation in clinical care by patients with breast cancer, permitting them to achieve a series of key clinical outcomes and improving quality of life. Digital integrated health ecosystems might be important tools for improving ongoing monitoring of physical status, psychological burden, and socioeconomic issues during the cancer survivorship trajectory.

Effectiveness of pain neuroscience education on somatosensory functioning after surgery for breast cancer: A double-blinded randomized controlled trial

Pain is one of the most prevalent and long-term adverse effects described by people who have undergone breast cancer surgery. Non-helpful perceptions and thoughts about pain may contribute to the transition of acute to persistent pain. Adding educational interventions to the current physical therapy program in this population may help to improve or prevent persistent pain. Pain neuroscience education (PNE) is a type of educational intervention that addresses the experience of pain in a broader sense by explaining pain not only from a biomedical perspective, but also from a psychological and social perspective. A double-blinded randomized controlled trial (EduCan trial) investigated whether PNE, in addition to a standard physiotherapy program immediately after surgery for breast cancer, was more effective on somatosensory functioning in the short (4 months postoperatively) and long term (18 months postoperatively), than providing a biomedical explanation for pain. Somatosensory functioning was evaluated using a self-reported questionnaire as well as a comprehensive quantitative sensory testing evaluation. The findings of this study revealed that adding six sessions of PNE to a standard physical therapy program (n = 184) did not result in a significantly different course of somatosensory functioning up to 18 months postoperatively as compared to biomedical pain education. These findings provide an interesting basis for future research into who should receive PNE after surgery for breast cancer (e.g., patient profiling or phenotyping) and how we can tailor it to the individual to increase its effectiveness.

A systematic review of the added value of perioperative pain neuroscience education

OBJECTIVE

To identify and summarize evidence about the benefits of perioperative pain neuroscience education (PNE) on pain-related and psychosocial outcomes.

METHODS

Included were reports written in English that carried out PNE or its synonyms; perioperative period; aged ≥ 18 years; interventional studies and observational studies. Secondary studies, conference abstracts, and editorials were excluded. There was no time limitation.

INFORMATION SOURCES

PubMed, Virtual Health Library, Cochrane Library, and Science Direct. Search: June 20th 2023. The risk of bias was assessed using the Joanna Briggs Institute checklists, and synthesis followed the recommendations of the Synthesis Without Meta-analysis (SWiM) guideline. Register: Center for Open Science website (10.17605/OSF.IO/ZTNEJ).

RESULTS

The sample consisted of 18 reports. For pain outcomes, it was not possible to attribute PNE benefits because ten reports found improvements in both intervention and control groups. For psychosocial outcomes, fourteen reports found benefits for PNE groups. All the analyzed reports showed low risk of bias.

CONCLUSION

PNE had additional benefits beyond those obtained with conventional treatment for psychosocial outcomes.

PRACTICAL IMPLICATIONS

Due to the lack of evidence, it was not possible to indicate the clinical use of PNE. It is suggested that further studies are needed aimed at clarifying the possible benefits.

Barriers and facilitators to physical activity in cancer survivors with pain: a systematic review

PURPOSE

Pain post-treatment is a debilitating symptom in the growing population of cancer survivors. While physical activity is an integral part of pain management, low levels of physical activity are often observed in this population. The aim of this systematic review is to gain insight into the barriers and facilitators to physical activity in cancer survivors afflicted with pain.

METHODS

In December 2021, a systematic search was conducted using PubMed and Web of Science. All studies exploring barriers and/or facilitators to physical activity in cancer survivors with pain were included. The methodological quality of the evidence was appraised with the Mixed Methods Appraisal Tool (version 2018).

RESULTS

Six articles were included. Current literature was limited and mostly focused on female breast cancer survivors. The identified barriers and facilitators could be categorized into six different domains: the logistical, symptoms, cognitive, clinical, social, and knowledge domain. The barrier of pain was reported as a barrier on its own that is closely linked to other barriers in this specific population.

CONCLUSION

Barriers and facilitators to physical activity were categorized in six different domains. The barrier of pain distinguishes itself and brings along additional obstacles such as anxiety, fear, and avoidance behavior. Current evidence is limited and focuses mostly on female breast cancer survivors. Further research in larger cohorts representing various subsets of cancer survivors with pain is warranted, as well as studies that implement these insights in physical activity interventions.

NEUROCANTRIAL: study protocol for a randomised controlled trial of a pain neuroscience education programme in adults with cancer pain

INTRODUCTION

Pain is the second most frequent symptom reported in patients with cancer among the main reasons for consultation. The incorporation of educational modalities in pain intervention processes has been suggested. This study aims to examine the efficacy of neuroscience pain education (PNE) in relation to pain, biopsychosocial variables and functional capacity in comparison with conventional treatment. It is hypothesised that an intervention based on PNE achieves better outcomes than conventional management, in terms of pain, biopsychosocial variables and functional capacity in adults with oncological pain.

METHODS AND ANALYSIS

This will be a single-blind, controlled clinical trial in which two groups will be compared using changes in pain as the primary measure. The first group will receive conventional treatment in addition to PNE, and participants will undergo an intervention of nine sessions (one session per week, for a total of 9 weeks), each lasting 30-40 min. Specifically, these sessions will teach biophysiological elements using metaphors that allow the adoption of these concepts related to pain. The second group will receive conventional treatment (pharmacological treatment). For this study, a sample size calculation was made based on the background, where 80 adults with oncological pain were required. An initial evaluation will be made to establish the baseline characteristics, and then, according to the randomisation, the assignment to the PNE group or the control group will be made and the two groups will be summoned again. Ten weeks later, for the intervention evaluation, the statistical analysis plan will be established by protocol and by intention-to-treat.

ETHICS AND DISSEMINATION

This protocol complies with all ethical considerations. The authors commit to presenting the study's results. This study was approved by the ethics committees of the Universidad Santiago de Cali, Clínica de Occidente/Angiografía de Occidente. The authors commit to presenting the study's results.

Effectiveness of Therapeutic Education in Patients with Cancer Pain: Systematic Review and Meta-Analysis

(1) Objective: To review the existing evidence on pain education in patients with pain derived from an oncological process. (2) Methods: A systematic review was conducted using the databases Pubmed, Web of Science, PEDro, and Scopus. The selected studies had to incorporate instruction about the neurophysiology of pain into their educational program. The target population was cancer patients who had suffered pain for at least one month. The methodological quality of the articles collected was assessed using the PEDro scale. (3) Results: Some 698 studies were initially identified, of which 12 were included in this review. Four different models of pain education programs were found in the studies' interventions. Pain intensity, pain experience, quality of life, pain tolerance, and catastrophism were the variables that appeared most frequently. (4) Conclusions: This review demonstrates that pain education in patients with cancer pain may produce effects such as decreased pain intensity and catastrophism. Knowledge about pain also seems to increase. However, no benefit was reported for patients' overall quality of life. Therefore, more research is needed to clarify the effects of these interventions on the oncology population.

Persistent pain management in an oncology population through pain neuroscience education, a multimodal program: PaiNEd randomized clinical trial protocol

INTRODUCTION

Pain is one of the most persistent symptoms after cancer treatment. The central nervous system can erroneously stay in its alarm phase, altering the pain experience of patients who have cancer. Pain neuroscience education (PNE) with multimodal approaches may benefit these patients.

OBJECTIVE

This protocol aims to determine the effectiveness of a PNE tool on pain, physical function and quality of life, as a supplement to a multimodal rehabilitation (MR) program in patients who had breast cancer (BC).

METHODS

An 8-week double-blinded randomized controlled trial will be conducted, including 72 participants who had BC and who have persistent pain, randomized into three groups: PNE program + MR program, traditional biomedical information + MR program and control group. The PNE program will include educational content that participants will learn through a mobile app and the MR program will include a concurrent exercise program and manual therapy. The primary outcome will be the perceived pain assessed using the Visual Analogue Scale and secondary outcomes are others related to pain, physical function and quality of life. All outcomes will be evaluated at baseline, at the end of the intervention and 6 months after the end of intervention.

DISCUSSION

The proposed study may help BC patients with persistent pain improve their pain experience, quality of life and provide for more adaptive pain-coping strategies. This protocol could propose an action guide to implement different integral approaches for the treatment of sequelae. This treatment option could be offered to this patient profile and it could be easily implemented in the healthcare systems due to its low costs.

Factors associated with upper limb function in breast cancer survivors

BACKGROUND

Breast cancer survivors may have side effects from treatment, such as impaired upper limb function after surgery, which may be affected by a range of factors.

OBJECTIVE

To analyze the association between upper limb function and strength, fear avoidance, and central sensitization symptoms among breast cancer survivors, and to explore how these variables are associated with upper limb function.

DESIGN

Validation cohort.

SETTING

Institutional practice at a public hospital.

PATIENTS

One hundred seventy-four breast cancer survivors who had been undergone surgery for a primary tumor.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Upper limb function was measured by the Upper Limb Functional Index (ULFI-Sp). Independent outcomes were: handgrip strength, which was measured using a Jamar dynamometer on the dominant side; fear avoidance, measured using the Fear-Avoidance Components Scale (FACS-Sp); and central sensitization symptoms, which were measured using the Central Sensitisation Inventory (CSI-Sp). A linear regression model explaining the ULFI-Sp results was constructed with the variables.

RESULTS

The regression model was significant (F = 46.826; p < .0001), and explained 45% of the variance of the ULFI values. All variables showed strong associations with upper limb function.

CONCLUSIONS

Greater upper limb function is associated with higher grip strength, lower fear-avoidance behavior and fewer central sensitization symptoms among breast cancer survivors. These variables explained 45% of the upper limb function in the regression model, and concur with earlier research showing that factors such as central sensitization symptoms and kinesiophobia negatively affect upper limb function in such patients. Clinicians should therefore take into account strength, fear avoidance, and central sensitization symptoms when considering interventions aimed at improving upper limb function among breast cancer survivors.

Feasibility and pilot testing of a personalized eHealth intervention for pain science education and self-management for breast cancer survivors with persistent pain: a mixed-method study

PURPOSE

Here, we describe the development and pilot study of a personalized eHealth intervention containing a pain science education program and self-management support strategies regarding pain and pain-related functioning in female survivors of breast cancer. First, we aimed to evaluate the eHealth intervention's acceptability, comprehensibility, and satisfaction; second, we aimed to assess its preliminary efficacy.

METHODS

A mixed-method study design was used. Breast cancer survivors with persistent pain were recruited. After 6 weeks of engagement with the eHealth intervention, acceptability, comprehensibility, and satisfaction were measured quantitatively with a self-constructed questionnaire and described qualitatively using focus groups. A joint display was used to present the meta-interferences between data. Efficacy was assessed via mixed effects models with repeated measures (outcomes assessed at baseline, 6 weeks, and 12 weeks).

RESULTS

Twenty-nine women with persistent pain after breast cancer surgery participated. Overall, the eHealth program was well received and experienced as easy to use and helpful. The eHealth intervention seems useful as an adjunct to comprehensive cancer aftercare. Efficacy estimates suggested a significant improvement in pain-related functioning, physical functioning, and quality of life.

CONCLUSION

A personalized eHealth intervention appears valuable for persistent pain management after breast cancer surgery. A large controlled clinical trial to determine effectiveness, and a full process evaluation, seems warranted.

Pain science education for children living with and beyond cancer: Challenges and research agenda

Pain in children living with and beyond cancer is understudied and undertreated. Pain science education (PSE) is a conceptual change strategy facilitating patients' understanding of the biopsychosocial aspects of pain. Preliminary studies on the adaptation of PSE interventions to adults with and beyond cancer provide a foundation for pediatric research. PSE could help childhood cancer survivors experiencing persistent pain and pain-related worry after active treatment. PSE may also help children receiving cancer treatment, providing them with a foundation of adaptive pain beliefs and cognitions, and preparing them for procedural and treatment-related pain. We direct this paper toward pediatric oncology clinicians, policy makers, and researchers working with children living with and beyond cancer. We aim to (a) identify challenges in adapting PSE for children living with and beyond cancer, (b) offer possible solutions, and (c) propose research questions to guide the implementation of PSE for children living with and beyond cancer.

The effect of exercise intensity on exercise-induced hypoalgesia in cancer survivors: A randomized crossover trial

Pain is experienced by people with cancer during treatment and in survivorship. Exercise can have an acute hypoalgesic effect (exercise-induced hypoalgesia; EIH) in healthy individuals and some chronic pain states. However, EIH, and the moderating effect of exercise intensity, has not been investigated in cancer survivors. This study examined the effect of low- and high-intensity aerobic exercise on EIH in cancer survivors after a single exercise session as well as a brief period of exercise training (2-weeks, three exercise sessions per week). Participants (N = 19) were randomized to low- (30%-40% Heart Rate Reserve (HRR) or high- (60%-70% HRR) intensity stationary cycling for 15-20 min. Pressure pain thresholds (PPT) were assessed over the rectus femoris and biceps brachii before and after a single exercise session and again after a short training period at the assigned intensity. Then, following a 6-week washout period, the intervention was repeated at the other intensity. After the first exercise session, high-intensity exercise resulted in greater EIH over the rectus femoris than low intensity (mean difference ± SE: -0.51 kg/cm2  ± 0.15, Cohen's d = 0.78, p = 0.004). After a 2-week training period, we found no difference in EIH between intensities (0.01 kg/cm2  ± 0.25, d = 0.00 p = 0.99), with comparable moderate effect sizes for both low- and high-intensity exercise, indicative of EIH. No EIH was observed over the biceps brachii of the arm at either low or high intensity. Low-intensity exercise training may be a feasible option to increase pain thresholds in cancer survivors.
