Cognitive-behavioral therapy for patients with chronic pain: Implications of gender differences in empathy

Recent Advances in Non-Invasive Digital Nursing Technologies for Chronic Pain Assessment and Management: An Integrative Review

AIM

This integrative review aims to identify what nurses currently offer through digital technology and their success in managing chronic pain.

DESIGN

An integrative review guided by Whittemore and Knafl was conducted.

DATA SOURCES

Five databases-CINAHL, Medline, PsycINFO, PubMed, and Scopus-were utilised to gather relevant studies from January 2018 to November 2024.

REVIEW METHODS

Selected studies were assessed using the Mixed Methods Appraisal Tool and the Joanna Briggs Appraisal Tool. Braun and Clarke's thematic analysis was applied to identify pertinent themes.

RESULTS

Digital nursing technologies such as telehealth and web-based interventions effectively deliver interventions to assess and manage chronic pain; these technologies can reduce healthcare resource utilisation and increase accessibility. This review highlights that nurses commonly deliver exercise, cognitive-behavioural therapy, acceptance and commitment therapy and self-management techniques through digital technology.

CONCLUSION

This review indicates that web-based interventions and telemedicine are the primary digital technologies employed by nurses for chronic pain management providing psychosocial interventions, with evidence supporting their effectiveness. Digital and web-based technology is essential to bridge healthcare access gaps as nurses can provide this successfully with minimal nursing support and cost to the patient.

IMPACT

Evidence supports nurses in providing psychosocial interventions for the management of chronic pain, particularly web-based psychosocial interventions. Nurses need to adopt digital technology to improve access to care and patient outcomes and to maintain professional development in an increasingly digital world.

The Benefits of Cognitive Therapeutic Exercise in Symptomatic Arnold-Chiari Syndrome Type I: A Case Report on Gait, Balance, and Pain Management

BACKGROUND

Chiari malformation is a rare congenital condition in which the cerebellar tonsils herniate through the foramen magnum, causing symptoms related to compression of the surrounding structures. Rehabilitation plays a key role in the pre- and post-operative management of the syndrome, as it can improve strength, range of motion, motor coordination, pain management, and performance of activities of daily living.

METHODS

This article presents the case of a 43-year-old woman with Chiari malformation 1B who underwent resection of the filum terminale. She presented as an outpatient at the University Hospital "G. Martino" in Messina, complaining of difficulty walking, balance problems, lumbar pain, and heaviness in the lower limbs. Following a multidisciplinary assessment, she underwent an 11-month rehabilitation protocol based on cognitive therapeutic exercise.

RESULTS

The patient achieved significant improvements in pain, mental confusion, and quality of life after treatment and at the 12-month follow-up.

CONCLUSIONS

The results of this study highlight the significant benefits of cognitive therapeutic exercises in Chiari malformation, with improvements in several key areas, including quality of life, pain management, and ability to perform activities of daily living.

Advancements in Modern Treatment Approaches for Central Post-Stroke Pain: A Narrative Review

PURPOSE OF REVIEW

Central post-stroke pain (CPSP) poses a multifaceted challenge in medical practice, necessitating a thorough and multidisciplinary approach for its diagnosis and treatment. This review examines current methods for addressing CPSP, highlighting both pharmacological and non-pharmacological therapies. It covers the mechanisms and clinical effectiveness of these treatments in managing CPSP and emphasizes the importance of personalized treatment plans, given the varied causes of CPSP.

RECENT FINDINGS

Recent advancements have illuminated diverse treatment modalities for CPSP. Pharmacotherapy spans from conventional analgesics to anticonvulsants and antidepressants, tailored to mitigate the neuropathic characteristics of CPSP. Non-pharmacological interventions, including physical therapy and psychological strategies, are pivotal in managing CPSP's chronic nature. For cases resistant to standard treatments, advanced interventions such as nerve blocks and surgical procedures like deep brain stimulation (DBS) or motor cortex stimulation (MCS) are considered. Additionally, innovative technologies such as neuromodulation techniques and personalized medicine are emerging as promising avenues to enhance therapeutic outcomes and improve quality of life for individuals grappling with CPSP.

SUMMARY

Modern approaches in managing CPSP require an interdisciplinary and patient-centric approach. Customizing treatment plans to address the specific etiology and symptoms of CPSP is crucial. Pharmacotherapy remains fundamental, encompassing medications such as anticonvulsants and antidepressants tailored to manage neuropathic pain. Integrating non-pharmacological interventions is crucial for providing comprehensive care. Additionally, investigating innovative technologies and personalized medicine presents promising opportunities to enhance treatment results and elevate the quality of life for those suffering from CPSP. Ultimately, an integrated approach that acknowledges the multifaceted nature of CPSP is essential for effective management and patient well-being.

Effectiveness of acceptance commitment therapy for head and neck cancer patients with body image distress in China: a study protocol for randomised controlled trial

INTRODUCTION

The head and neck comprise vital organs and are apparent human body parts. Tumours here impair physical and sensory functions as well as appearance and social interactions, leading to body image distress (BID) and threatening mental health and quality of life. Acceptance and commitment therapy has shown effectiveness in improving BID in groups such as breast cancer patients. This study aims to apply this therapy to intervene in head and neck cancer (HNC) patients, aiming to improve BID and promote better psychological well-being.

METHODS AND ANALYSIS

This study is a prospective, parallel-group, randomised controlled trial. A total of 64 HNC patients will be allocated to either an intervention group or a control group. The intervention group will engage in a 3 week, six-session group-based acceptance and commitment therapy programme, while the control group will receive standard treatment. The primary outcome is cancer-related BID, and secondary outcomes are HNC-related BID, psychological flexibility, coping style and psychological distress. These indicators will be measured at baseline, postintervention and 1 month following the intervention's completion.

ETHICS AND DISSEMINATION

The trial has received approval from the Institutional Review Board of Shanghai Proton and Heavy Ion Hospital (2308-67-02). The study results will be shared through peer-reviewed journals and conferences.

TRIAL REGISTRATION NUMBER

Establishing Geriatric Opiate Use Patterns in Trauma

Introduction: There is evidence that providers often overprescribe opiates in the postoperative period. Despite an ever-growing geriatric population, there is little research detailing current opiate usage in older patients after trauma. This population presents a unique set of challenges for pain management and prescription drug dependence due to sensitivity, a narrow therapeutic window, and high rates of pre-existing polypharmacy.Objective: Assess the use of narcotics in geriatric trauma patients with various injury patterns to establish a reference point for future intervention for reduction in narcotic dependence.Methods: We created a database of trauma patients' age ≥65 years admitted to a single level 1 trauma center in the Southeastern United States during the 2019 calendar year. Information gathered included patient factors, injury patterns, operative intervention, pain medications prescribed during hospitalization and at discharge, total and average daily morphine milligram equivalents (MME) inpatient and outpatient, and requests/prescriptions for narcotics at follow-up.Results: In 2019, there were 475 patients aged ≥65 admitted to our level 1 trauma center for acute traumatic injuries. 219 of those patients required operative intervention. Average total inpatient MME for this cohort was 169.0 with average daily MME of 22.89. The average total prescribed MME upon discharge was 79.27. There were 29 patients documented to request narcotic prescription refill at time of clinic follow-up, 27 of whom were prescribed a narcotic medication at follow-up.Conclusion: This dataset establishes a reference point for opiate use in geriatric trauma patients to facilitate further research for mitigation of risk in this population.

Unraveling pain experience and catastrophizing after cognitive behavioral therapy

Pain experiences are often complex with catastrophic cognitions, emotions, and behaviors. Cognitive behavioral therapists share the work of unraveling these complex experiences with their patients. However, the change process underlying the unraveling of the pain experience have not yet been quantified. We used an interrelationship-focused network model to examine the way an undifferentiated conceptualization between cognition and pain experience changed via group cognitive-behavioral therapy (CBT). Overall, 65 participants (77.4% of all patients who entered the intervention) were included in the analysis; they attended the total of 12 weekly group CBT and filled the Short-Form McGill Pain Questionnaire and the pain catastrophizing questionnaire. Before treatment, there were no edges in the partial correlation-based network because of large covariation across items. After treatment, many edges appeared and, particularly strong couplings were found between items within the same subscale. The formative shift from a non-edged pre-treatment network to a mature post-treatment network may indicate that patients were able to conceptualize these symbolic constructs better. These results are probably of interest to clinicians and would be consistent with the fundamental monitoring process of CBT.

Exploring the Role of Community Pharmacists in Pain Management: Enablers and Challenges

Pain is a common complaint, and the consumption of analgesics is prevalent. Community pharmacists, as primary contact points for patients, can play a crucial role in guiding patients toward rational pharmacotherapy or alternative pain management strategies. However, there are no specific educational curricula or standard guidelines to support this role, and the perception of this potential role is not well known. We conducted an anonymous online questionnaire among community pharmacists in Norway to assess their knowledge, perspectives, and willingness to engage in pain care. The survey also explored potential facilitators and barriers, and the use of any current guidelines. Seventy-one community pharmacists participated from various regions in Norway. Findings revealed that community pharmacists felt knowledgeable and willing to engage in pain management but anticipated barriers such as time constraints and a lack of standard guidelines. Participants also highlighted the need for better collaboration with other healthcare professionals and continuous professional development to enhance their role. To optimize the role of community pharmacists in pain management, therefore, integrating them into multidisciplinary healthcare teams, minimizing barriers, and providing continuous education and standard guidelines seem essential. This approach can empower community pharmacists and improve pain management outcomes.

Effectiveness of primary care interventions in conjointly treating comorbid chronic pain and depression: a systematic review and meta-analysis

BACKGROUND

Chronic pain and depression are highly comorbid, but the lack of consensus on the best treatment strategies puts patients at high risk of suboptimal care-coordination as well as health and social complications. Therefore, this study aims to quantitatively assesses how effective different primary care interventions have been in treating the comorbid state of chronic pain and depression. In particular, this study evaluates both short-term outcomes-based specifically on measures of chronic pain and depression during an intervention itself-and long-term outcomes or measures of pain and depression in the months after conclusion of the formal study intervention.

METHODS

This study is a systematic review and meta-analysis of randomised-controlled trials (RCTs) enrolling patients with concurrent chronic pain and depression. Intensity and severity of pain and depression symptoms were the primary outcomes. The main inclusion criteria were RCTs that: (i) enrolled patients diagnosed with depression and chronic pain, (ii) occurred in primary care settings, (iii) reported baseline and post-intervention outcomes for chronic pain and depression, (iv) lasted at least 8 weeks, and (v) used clinically validated outcome measures. Risk of bias was appraised with the Risk of Bias 2 tool, and GRADE guidelines were used to evaluate the quality of evidence.

RESULTS

Of 692 screened citations, 7 multicomponent primary care interventions tested across 891 patients were included. Meta-analyses revealed significant improvements in depression at post-intervention (SMD = 0.44, 95% CI [0.17, 0.71], P = 0.0014) and follow-up (SMD = 0.41, 95% CI [0.01, 0.81], P = 0.0448). Non-significant effects were observed for chronic pain at post-intervention (SMD = 0.27, 95% CI [-0.08, 0.61], P = 0.1287) and follow-up (SMD = 0.13, 95% CI [-0.3, 0.56], P = 0.5432).

CONCLUSIONS

Based on the results of the meta-analysis, primary care interventions largely yielded small to moderate positive effects for depressive symptoms and no significant effects on pain. In one study, stepped-care to be more effective in treatment of comorbid chronic pain and depression than other interventions both during the intervention and upon post-intervention follow-up. As such, depression appears more amenable to treatment than pain, but the number of published RCTs assessing both conditions is limited. More research is needed to further develop optimal treatment strategies.

Chronic pain, a narrative review for the internist in 2024

Chronic pain is a complex and pervasive condition that profoundly affects individuals physically, emotionally, and socially. This narrative review aims to provide internists and healthcare professionals with a comprehensive overview of chronic pain, its various types, pathophysiology, epidemiology, clinical presentation, evaluation tools, and the burden it imposes on patients. We discuss the importance of recognizing chronic pain as a legitimate condition and the need for a compassionate, individualized approach to management. The review highlights the role of both pharmacological and non-pharmacological interventions in treating chronic pain, emphasizing the value of reducing pain, improving function, enhancing quality of life, and minimizing medication dependence. Additionally, we touch upon the promising future of pain treatment, including advancements in technology and personalized medicine. While not a comprehensive systematic review, this article serves as a valuable resource for healthcare providers seeking to understand, manage, and treat chronic pain effectively in their daily practice.

Chronic nonspecific multiple-sites pain [CNMSP] of unknown etiology: Biopsychosocial method of evaluation for the primary care level

Background

Understanding and dealing with chronic nonspecific pain (CNP) is the important entity at primary care hospital. Chronic nonspecific multiple-site pain [CNMSP] of unknown etiology creates diagnostic and therapeutic challenges for primary care physicians due to lack of guidance regarding evaluation and treatment.

Aims and Objectives

To classify and formulate the evaluation, treatment strategies, and prediction of prognosis of patients with CNMSP of unknown etiology.

Methods

Patients present with CNMSP of more than 3-month duration without any obvious medical cause. The biopsychosocial [BPS] model with 3P model was applied to see the biological, psychological, and social factors behind persistence. Finally, patients were classified into four groups for evaluation response to treatment and relapse rates in 12-month follow-up.

Results

Of the total 243 patients of CNMSP, 243 [96.3%] were females. Sixty [24.7%] patients had short duration, and 183 [75.3%] had long duration. Headache was in 115 [47%], low back pain ± leg pain in 96 [39.4%], cervical pain ± shoulder/arm pain in 83 [34.1%], and diffuse body pain in 50 [20.5%] in various combinations. A total of 155 [63.8%] patients had high somatization-sensitization index (SSI), and 144 [59.3%] had low ferritin level. Group 1 [high SSI and low ferritin] had 37.9% of patients, group 2 [high SSI and normal ferritin] had 25.9% of patients, group 3 [low to medium SSI with low ferritin] had 21.4% of patients, and group 4 [low to medium SSI with normal ferritin] had 14.8% of patients. Response to pain symptoms was better in group 1, and relapse rate was higher in group 2.

Conclusion

CNMSP of unknown etiology itself is a heterogeneous entity, and assessment based on the BPS model can be very useful to understand the treatment plan and outcome of these patients.

Adverse Events of the Long-Term Use of Opioids for Chronic Non-cancer Pain: A Narrative Review

BACKGROUND

The long-term use of opioids for chronic non-cancer pain (CNCP) has drawn more attention and debate. Although opioids are frequently used to treat chronic pain, their effectiveness and safety over extended periods are still unknown.

OBJECTIVES

The purpose of this review is to provide an overview of what is currently known about the adverse events of long-term use of opioids in CNCP. It also delivers patient-centered strategies designed to mitigate these risks.

METHODS

We conducted a literature search in PubMed, MEDLINE, EMBASE, and Web of Science databases. Search terms included CNCP, pain pathophysiology, opioid pharmacodynamics, opioid prescribing trends, guidelines for opioid use, and opioid side effects.  Results: Our review highlights that while opioids may provide short-term relief from CNCP, their effectiveness diminishes over time due to the development of opioid tolerance. This tolerance often leads to increased dosages, which can subsequently result in opioid dependence. Additionally, long-term opioid therapy is associated with a spectrum of adverse effects, including constipation, drowsiness, respiratory depression, and potential for drug interactions. Furthermore, our review indicates that alternative pain management strategies play a crucial role in controlling CNCP. They offer significant benefits with fewer adverse events. These strategies include non-opioid medications, physical therapy, cognitive-behavioral therapy (CBT), various interventional procedures, injection therapy, and acupuncture.

CONCLUSION

Using opioids to manage CNCP presents several challenges. Given these challenges, alternative treatments are being considered as viable options. Moreover, it is crucial to customize treatment plans to align with the patients' specific health requirements, existing conditions, and potential risks to ensure the best possible outcomes.

A Journey Through Tapering

Living with rheumatoid arthritis (RA) for almost 40 years has not been an easy journey. My disease has been severe and difficult to manage; from the beginning there were challenges getting a diagnosis and in finding medications that were effective long term. Thirty years ago, unable to cope with the extreme pain and with 3 children aged 8, 11, and 13 who needed a functioning mother, my doctor prescribed an opioid. This medication gave me back some quality of life but taking opioids is not without significant risks. No one discussed the challenges I would face if and when the time came to stop taking them. With the opioid crisis there has been more pressure from government and medical licensing bodies to implement policies to restrict access for patients prescribed opioids and to encourage tapering. With the change in policy additional funding and resources are needed to help patients through the process but those supports do not exist across Canada.

Cognitive behavioural therapy (CBT) with and without exercise to reduce fear of falling in older people living in the community

BACKGROUND

Fear of falling (FoF) is a lasting concern about falling that leads to an individual avoiding activities that he/she remains capable of performing. It is a common condition amongst older adults and may occur independently of previous falls. Cognitive behavioural therapy (CBT), a talking therapy that helps change dysfunctional thoughts and behaviour, with and without exercise, may reduce FoF, for example, by reducing catastrophic thoughts related to falls, and modifying dysfunctional behaviour.

OBJECTIVES

To assess the benefits and harms of CBT for reducing FoF in older people living in the community, and to assess the effects of interventions where CBT is used in combination with exercise.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 1, 2023), MEDLINE Ovid (from 1946 to 11 January 2023), Embase Ovid (from 1980 to 11 January 2023), CINAHL Plus (Cumulative Index to Nursing and Allied Health Literature) (from 1982 to 11 January 2023), PsycINFO (from 1967 to 11 January 2023), and AMED (Allied and Complementary Medicine from 1985 to 11 January 2023). We handsearched reference lists and consulted experts for identifying additional studies.

SELECTION CRITERIA

This review included randomised controlled trials (RCTs), quasi-RCTs, and cluster-RCTs assessing CBT with and without exercise interventions compared to control groups with sham-treatment, or treatment as usual. We defined CBT as a collaborative, time-limited, goal-oriented, and structured form of speaking therapy. Included studies recruited community-dwelling older adults, with a mean population age of at least 60 years minus one standard deviation, and not defined by a specific medical condition.

DATA COLLECTION AND ANALYSIS

Two review authors used standard methodological procedures expected by Cochrane. For continuous data, as assessed by single- or multiple-item questionnaires, we report the mean difference (MD) with 95% confidence interval (CI) when studies used the same outcome measures, and standardised mean difference (SMD) when studies used different measures for the same clinical outcome. For dichotomous outcomes, we reported the treatment effects as risk ratios (RR) with 95% CIs. We measured the primary outcome, FoF, immediately, up to, and more than six months after the intervention. We analysed secondary outcomes of activity avoidance, occurrence of falls, depression, and quality of life when measured immediately after the intervention. We assessed risk of bias for each included study, using the GRADE approach to assess the certainty of evidence.

MAIN RESULTS

We selected 12 studies for this review, with 11 studies included for quantitative synthesis. One study could not be included due to missing information. Of the 11 individual studies, two studies provided two comparisons, which resulted in 13 comparisons. Eight studies were RCTs, and four studies were cluster-RCTs. Two studies had multiple arms (CBT only and CBT with exercise) that fulfilled the inclusion criteria. The primary aim of 10 studies was to reduce FoF. The 11 included studies for quantitative synthesis involved 2357 participants, with mean ages between 73 and 83 years. Study total sample sizes varied from 42 to 540 participants. Of the 13 comparisons, three investigated CBT-only interventions while 10 investigated CBT with exercise. Intervention duration varied between six and 156 hours, at a frequency between three times a week and monthly over an eight- to 48-week period. Most interventions were delivered in groups of between five and 10 participants, and, in one study, up to 25 participants. Included studies had considerable heterogeneity, used different questionnaires, and had high risks of bias. CBT interventions with and without exercise probably improve FoF immediately after the intervention (SMD -0.23, 95% CI -0.36 to -0.11; 11 studies, 2357 participants; moderate-certainty evidence). The sensitivity analyses did not change the intervention effect significantly. Effects of CBT with or without exercise on FoF may be sustained up to six months after the intervention (SMD -0.24, 95% CI -0.41 to -0.07; 8 studies, 1784 participants; very low-certainty evidence). CBT with or without exercise interventions for FoF probably sustains improvements beyond six months (SMD -0.28, 95% CI -0.40 to -0.15; 5 studies, 1185 participants; moderate-certainty of evidence). CBT interventions for reducing FoF may reduce activity avoidance (MD -2.57, 95% CI -4.67 to -0.47; 1 study, 312 participants; low-certainty evidence), and level of depression (SMD -0.41, 95% CI -0.60 to -0.21; 2 studies, 404 participants; low-certainty evidence). We are uncertain whether CBT interventions reduce the occurrence of falls (RR 0.96, 95% CI 0.66 to 1.39; 5 studies, 1119 participants; very low-certainty evidence). All studies had a serious risk of bias, due to performance bias, and at least an unclear risk of detection bias, as participants and assessors could not be blinded due to the nature of the intervention. Downgrading of certainty of evidence also occurred due to heterogeneity between studies, and imprecision, owing to limited sample size of some studies. There was no reporting bias suspected for any article. No studies reported adverse effects due to their interventions.

AUTHORS' CONCLUSIONS

CBT with and without exercise interventions probably reduces FoF in older people living in the community immediately after the intervention (moderate-certainty evidence). The improvements may be sustained during the period up to six months after intervention (low-certainty evidence), and probably are sustained beyond six months (moderate-certainty evidence). Further studies are needed to improve the certainty of evidence for sustainability of FoF effects up to six months. Of the secondary outcomes, we are uncertain whether CBT interventions for FoF reduce the occurrence of falls (very low-certainty evidence). However, CBT interventions for reducing FoF may reduce the level of activity avoidance, and may reduce depression (low-certainty evidence). No studies reported adverse effects. Future studies could investigate different populations (e.g. nursing home residents or people with comorbidities), intervention characteristics (e.g. duration), or comparisons (e.g. CBT versus exercise), investigate adverse effects of the interventions, and add outcomes (e.g. gait analysis). Future systematic reviews could search specifically for secondary outcomes.

Past Adversity Influencing Now (PAIN): perspectives on the impact of temporal language on the persistence of pain

Persistent pain is a significant healthcare issue, often unresponsive to traditional treatments. We argue for incorporating non-biomedical perspectives in understanding pain, promoting more comprehensive solutions. This article explores how language, specifically time-related terms, may affect the persistence (stickiness) of pain. We delve into how language influences one's experience of the world, especially in understanding pain through spatial metaphors. Notably, time perceptions differ across languages and cultures and there is no absolute construct of temporal pain experience. In English, time is viewed linearly as past, present, and future. We introduce a framework called Past Adversity Influencing Now (PAIN) which includes various temporal phases of pain; Past Perfect, Past Imperfect, Present, Future Imperfect, and Future Perfect. We suggest that past negative memories (emotional memory images) can "trap" individuals in a "sticky" pain state. We speculate that the process of diagnosing pain as "chronic" may solidify this "stickiness", drawing from the ancient Greek idea of "logos", where pain communicates a message across time and space needing recognition. Our PAIN framework encourages examining pain through a temporal lens, guiding individuals towards a more positive future.

Cognitive behavior therapy as dermatological treatment: a narrative review

Cognitive behavior therapy (CBT) is efficacious in treating numerous psychological disorders. It is also effective in combination with medication for chronic pain, diabetes, and other diseases. Patients with skin disease report high levels of stress, anxiety, and negative feelings.

Objective

To summarize the findings on the utility of CBT for the improvement of skin status and quality of life in patients with dermatological conditions.

Methods

PubMed and Google Scholar databases were searched for relevant articles from database inception to the time of search (October 20, 2021). A total of 30 included studies featured 10 on psoriasis, 11 on atopic dermatitis, 4 on vitiligo, 4 on acne, and 1 study on alopecia areata.

Results

Several studies, including randomized controlled trials with large study samples, support the effectiveness of CBT and Internet CBT for a number of dermatological conditions. Patients who completed CBT courses were less likely to rely on dermatological healthcare during follow-up.

Limitations

There are a limited number of studies discussing the implementation of CBT for alopecia, acne, and vitiligo.

Conclusion

Patients who underwent CBT or Internet CBT in addition to skin care demonstrated improvement with quality of life and severity of skin disease as compared to controls only receiving standard of care treatment.

Pain Empathy and Its Association with the Clinical Pain in Knee Osteoarthritis Patients

Objective

Knee osteoarthritis (KOA) is a painful chronic disorder. Evidence has shown that a history of chronic pain plays an important role in shaping empathy. Empathy, a valuable indicator of social functioning that refers to an individual's ability to share the experiences of others, however, has been overlooked in KOA patients. This study aimed to investigate empathy and its association with clinical pain in KOA patients.

Methods

KOA patients (n=47) and healthy controls (HCs, n=44) completed two empathy-for-pain tasks: a pain judgment task in which participants judged whether a person in an image felt pain or not, and a pain rating task in which they estimated pain intensity for themselves and others. The Interpersonal Reactivity Index was used to measure participants' trait empathy, and clinical severity and psychological factors were assessed using relevant instruments.

Results

Compared to HCs, KOA patients showed higher accuracy when judging pain and non-pain images and reported overall higher pain intensity when rating for themselves and others. KOA patients also showed greater personal distress than HCs in terms of their self-reported empathy. Moreover, pain catastrophizing particularly mediated the relationship between pain severity and pain ratings for others, and depression, anxiety, and pain catastrophizing all mediated the association between pain severity and empathy-induced personal distress.

Conclusion

These findings suggest that patients with KOA have increased empathy, demonstrated by elevated sensitivity to pain-related scenes and intense emotional responses.

Síndrome de boca ardiente, abordaje otorrinolaringológico. Revisión bibliográfica sistemática

Introducción y objetivo: El síndrome de boca ardiente (SBA) es una afección crónica, que cursa con quemazón o dolor de la mucosa bucal, afectando predominantemente a mujeres de edad media. Puede aparecer como cuadro primario o bien de forma secundaria. La fisiopatología de esta entidad es bastante desconocida. Existe un amplio abanico terapéutico, pero por lo general precisa de un abordaje multidisciplinar. Nuestra intención es realizar una puesta al día de la enfermedad para poder hacerla frente en la consulta de otorrinolaringología. Método: Revisión bibliográfica de la literatura. Fecha de publicación limitada de 2012 a 2022. Resultados: El SBA presenta una etiopatogenia de carácter multifactorial. Para su diagnóstico es necesario realizar una exhaustiva anamnesis y exploración. Se diferencian 3 tipos distintos de SBA, siendo el tipo II el más frecuente y el más refractario a la terapia. El adecuado tratamiento se fundamenta en un correcto diagnóstico y debe ser multidisciplinar. Discusión: Es importante resaltar que es una entidad benigna. Los tratamientos son variados y no hay ninguno que destaque sobre el resto, lo que dificulta el manejo de estos pacientes. Aunque la bibliografía sobre este síndrome es abundante, no se han producido en los últimos años, importantes innovaciones en cuanto a la etiología y tratamiento. Conclusiones: La anamnesis y los estudios de laboratorio son fundamentales para descartar casusas secundarias de la enfermedad. La terapia es diversa y debe incluir derivación a salud mental como parte del manejo multidisciplinar.  

Efficiency of Associating Therapeutic Patient Education with Rehabilitation in the Management of Chronic Low Back Pain: A Randomized Controlled Trial

BACKGROUND

This study aimed to assess the benefits of associating rehabilitation with therapeutic patient education (TPE) to decrease fear-avoidance belief and pain and improve function in adults with chronic low back pain (CLBP).

METHODS

This randomized controlled study included 100 patients with CLBP according to the CONSORT (Consolidated Standards of Reporting Trials) guidelines. The patients were divided into two teams: group A that participated in the TPE in association with rehabilitation and group B that received rehabilitation only. Pain and functional amelioration were assessed initially (T0) and at the end of the program (T1) using a visual analog scale at rest, work, and activity, and the Echelle d'Incapacité Fonctionnelle pour l'Évaluation des Lombalgies scale. Psychological and apprehension and avoidance assessments were also conducted, including the evaluation of depression, anxiety, fear-avoidance belief, and kinesiophobia using the Hospital Anxiety and Depression Scale, Fear-Avoidance Beliefs Questionnaire, and Tampa scale of kinesiophobia scale.

RESULTS

The evaluation of progression initially (T0) and then at the end of the program (T1) revealed a significant reduction in pain at rest (P=0.00) and while working (P=0.00) and doing physical activity (P=0.03); a decrease in anxiety (P=0.03), fear-avoidance belief (P=0.03), and kinesiophobia (P=0.02); and an improvement in function (P=0.00) for patients in group A without amelioration of depression (P=0.15). Concerning group B, we identified a significant regression in pain at rest (P=0.001) and while working (P=0.03) and doing physical activity (P=0.00); depression (P=0.01); fear-avoidance beliefs (P=0.00); and kinesiophobia (P=0.002). Comparison between the groups revealed that associating TPE with rehabilitation resulted in a more significant improvement in function (P=0.00), anxiety (P=0.00), fear-avoidance belief (P=0.00), and kinesiophobia (P=0.00).

CONCLUSION

Associating TPE with rehabilitation improved function and reduced fear, false beliefs, and kinesiophobia of movement in patients with CLBP.

Preliminary study: quantification of chronic pain from physiological data

Supplemental Digital Content is Available in the Text.

Preliminary evidence suggests that physiological variables collected with our low-cost pain meter are correlated with chronic pain, both for individuals and populations.

Introduction:

It is unknown if physiological changes associated with chronic pain could be measured with inexpensive physiological sensors. Recently, acute pain and laboratory-induced pain have been quantified with physiological sensors.

Objectives:

To investigate the extent to which chronic pain can be quantified with physiological sensors.

Methods:

Data were collected from chronic pain sufferers who subjectively rated their pain on a 0 to 10 visual analogue scale, using our recently developed pain meter. Physiological variables, including pulse, temperature, and motion signals, were measured at head, neck, wrist, and finger with multiple sensors. To quantify pain, features were first extracted from 10-second windows. Linear models with recursive feature elimination were fit for each subject. A random forest regression model was used for pain score prediction for the population-level model.

Results:

Predictive performance was assessed using leave-one-recording-out cross-validation and nonparametric permutation testing. For individual-level models, 5 of 12 subjects yielded intraclass correlation coefficients between actual and predicted pain scores of 0.46 to 0.75. For the population-level model, the random forest method yielded an intraclass correlation coefficient of 0.58. Bland–Altman analysis shows that our model tends to overestimate the lower end of the pain scores and underestimate the higher end.

Conclusion:

This is the first demonstration that physiological data can be correlated with chronic pain, both for individuals and populations. Further research and more extensive data will be required to assess whether this approach could be used as a “chronic pain meter” to assess the level of chronic pain in patients.

Is Empathy Associated with Gambling and Its Addiction? A Scoping Review of Empirical Studies

Considering the low levels of empathy associated with substance-related addictions and the similarities between gambling disorder (GD) and substance-related addiction, understanding the relationship between empathy and GD may clarify the mechanism of addiction development. This scoping review aimed to evaluate the empirical evidence for the potential protective role of emotional and cognitive empathy against GD development via internalizing and/or externalizing pathways. We followed the preferred reporting items for systematic review and meta-analyses extension for scoping reviews and 11 articles met the inclusion criteria. Although most of the reviewed studies used correlational designs and non-gambling-specific samples, this review highlights (1) significant relationships between both types of empathy and the neural activity of gambling behaviors, and (2) reduced cognitive empathy (i.e., fantasy and perspective taking) and increased emotional empathy (i.e., personal distress) among problem gamblers than their gambling counterparts. Despite the lack of studies directly testing the protective role of empathy against GD, the existing studies (n = 8) nevertheless shed light on the potential protective effects of both types of empathy on GD development. This review identified research gaps, which can be addressed in future studies by discovering the underlying mechanisms (e.g., internalizing and externalizing pathways) of these relationships. Experimental or longitudinal studies in gamblers investigating how different types of empathy are associated with GD via these pathways are called for as their findings have implications for prevention and intervention designs for GD and other addictive disorders.

A systematic review of treatment for patients with burning mouth syndrome

BACKGROUND

Burning mouth syndrome is a chronic idiopathic intractable intraoral dysaesthesia that remains a challenge to clinicians due to its poorly understood pathogenesis and inconsistent response to various treatments.

AIM

This review aimed to study the short- (≤3 months) and long-term (>3 months) effectiveness and sustainable benefit of different burning mouth syndrome treatment strategies and the associated side effects.

MATERIALS AND METHODS

Randomised controlled trials of burning mouth syndrome treatment compared with placebo or other interventions with a minimum follow up of 2 months were searched from the PubMed, Embase and Cochrane database (published to July 2020).

RESULTS

Twenty-two studies were selected based on the inclusion and exclusion criteria and analysed. Nine categories of burning mouth syndrome treatment were identified: Anticonvulsant and antidepressant agents, phytomedicine and alpha lipoic acid supplements, low-level laser therapy, saliva substitute, transcranial magnetic stimulation, and cognitive behaviour therapy. Cognitive behaviour therapy, topical capsaicin and clonazepam, and laser therapy demonstrated favourable outcome in both short- and long-term assessment. Phytomedicines reported a short-term benefit in pain score reduction. The pooled effect of alpha lipoic acid (ALA) pain score improvement was low, but its positive effects increased in long term assessment.

CONCLUSION

A more significant volume in terms of sample size, multi-centres, and multi-arm comparison of therapeutic agents with placebo and longitudinal follow-up studies is recommended to establish a standardised burning mouth syndrome treatment protocol. Further studies are required to assess the analgesic benefits of topical clonazepam and capsaicin, alternative medicines with neurodegenerative prevention capability and psychology support in treating burning mouth syndrome and reducing systemic adverse drug reactions.Registration International Prospective Register of Systematic Reviews (PROSPERO):Protocol ID - CRD42020160892.

Nurses’ Knowledge and Practicing Level of Cognitive Behavioral Pain Relief Methods in Public Hospitals of Eastern Ethiopia

Introduction

Despite the fact that cognitive behavioral therapy is regarded as a superior pain relief method and an alternative to drug therapy, little is known about its scope of application and determinant factors. As a result, the study sought to assess nurses’ knowledge and practicing level of cognitive behavioral pain relief methods in public hospitals in eastern Ethiopia.

Objective

To assess the knowledge and practicing level of cognitive behavioral pain relief among nurses working in public hospitals of eastern Ethiopia.

Methods

A cross-sectional study was conducted among randomly selected 390 nurses. The data were collected using a self-administered questionnaire. The data were entered into Epi-data 3.1 and exported to SPSS 22 for analysis. Bivariate and multivariate logistic regression models were used to identify factors associated with cognitive behavioral therapy.

Result

In this study, more than half (54.1%) of the respondents had good cognitive behavioral methods practicing levels. Nearly two-thirds (58.8%) of the participants had adequate knowledge about pain relief methods. Having adequate knowledge (adjusted odds ratio [AOR] 2.664; 95% confidence interval [CI]: 1.75, 4.7), having training (AOR 1.7; 95% CI: 1.03, 3.01), and positive attitude (AOR 4.02; 95% CI: 4.5, 12.4) were significantly associated with cognitive behavioral therapy.

Conclusion

In this study, more than half of nurses had good cognitive behavioral methods practicing levels. Having a positive attitude, being knowledgeable, and having training were determinant factors in the practice of cognitive behavioral therapy. Continuing education and training should be considered for nurses to enhance their cognitive behavioral therapy practice.

Modulating the Activity of the VMPFC With tDCS Alters the Social Framing Effect

Numerous experimental studies have replicated the social framing effect-the observation that people’s decisions related to economic benefits and feelings depend on the method of presentation. Previous neuroimaging studies have shown that the ventromedial prefrontal cortex (VMPFC) plays a part in the influence of framing and how individuals think about the feelings of others. Based on this, we used transcranial direct current stimulation (tDCS) to modulate neuronal activity in the VMPFC to determine the likelihood of a direct association between VMPFC activity and the social framing effect. Subsequently, in three stimulation treatments, we assessed the presence of the social framing effect, as demonstrated by a disparity between harm degree and help degree. The findings revealed a social framing effect in the participants in the control group and the sham treatment but no social framing effect in the participants in the anodal or cathodal treatments. Furthermore, sex differences were observed in the sham treatment’s social framing effect, whereas no sex differences were observed in the anodal or cathodal treatments. The participants tended to harm the victim after receiving anodal or cathodal tDCS over the VMPFC and did not change their helping behaviour in any stimulations. Consequently, a clear causal link between the behaviour of the VMPFC and the social framing effect was found in the present research.

Complex Regional Pain Syndrome: A Comprehensive Qualitative Research Study on Unmet Needs in the "Patient Journey"

Purpose

This qualitative research study aimed to characterize the "patient journey" for patients with complex regional pain syndrome (CRPS) and identify the unmet needs related to the management and treatment of the condition for healthcare providers (HCPs), patients, and their caregivers.

Materials and Methods

Multifaceted, dynamic methodology, iteratively gathering cognitive, emotional and social insights, was used to support and conduct in-depth, immersion interviews across the USA with 59 HCPs in-office and in roundtable discussions, and 20 patient-support partner dyads in-home.

Results

Patients were aged >18 years, primarily female, and all were diagnosed with CRPS (limited to type 1 in this patient cohort). Results show that the current state of CRPS treatment may fall short in multiple key areas. In some cases, poor awareness of CRPS causes delayed diagnoses impacting the opportunity for early treatment, resulting in long-term poor health outcomes. Consequently, the CRPS "patient journey" may be characterized by clinical frustration of physicians and disappointment for some patients. The poor treatment experiences and outcomes for some patients and HCPs may build the perception of a non-collaborative relationship. HCPs and patients agree that an effective treatment would be one that addresses CRPS rather than its symptoms, and the availability of such an option would transform the treatment experience.

Conclusion

CRPS leads to cognitive, social and emotional burdens for patients and their caregivers. There is an unmet need for improved CRPS disease awareness and successful therapeutic options to aid in earlier diagnoses, effective treatment and better outcomes for HCPs, patients, and their caregivers.

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.

The influence of cognitive behavioral therapy on lumbar spine surgery outcomes: a systematic review and meta-analysis

PURPOSE

As more patients undergo lumbar spine surgery, novel interventions may improve physical and mental health outcomes. Few studies summarize the benefit of cognitive behavioral therapy (CBT) among lumbar spine surgery patients. This study collects randomized control trial data to investigate the influence of CBT on patient reported outcomes among lumbar spine surgery patients.

METHODS

Our study used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and a medical library expert assisted in searching PubMed/MEDLINE, Scopus, CINAHL, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, PsycINFO, and Google Scholar. We calculated standardized mean differences (SMD) to evaluate the effect size of CBT versus control groups with a sensitivity analysis.

RESULTS

Our meta-analysis included seven studies with a total of 531 patients. The majority of included studies evaluated lumbar fusion, with preoperative CBT performed by physiotherapists. The largest effects were observed for overall quality of life (SMD = 0.55 [95% CI 0.05, 1.05], p < 0.001, I² = 86.7%) and psychological outcomes (SMD = 0.61 [95% CI 0.28, 0.94], p < 0.001, I² = 89.7%) though disability and pain outcomes also favored CBT intervention. Included studies demonstrated low overall bias but large heterogeneity. Sensitivity analysis demonstrated negligible study design differences and revealed moderators including CBT session frequency and final follow-up duration (p < 0.001).

CONCLUSION

Compared to usual care or alternative therapy control arms, CBT delivered the most improvement with overall quality of life and psychological outcomes. Among appropriately selected patients, CBT could improve perioperative disability, pain, quality of life, and psychological health following lumbar spine surgery.

Neural Mechanisms of Acceptance and Commitment Therapy for Chronic Pain: A Network-Based fMRI Approach

Over 100 million Americans suffer from chronic pain (CP), which causes more disability than any other medical condition in the United States at a cost of $560-$635 billion per year (Institute of Medicine, 2011). Opioid analgesics are frequently used to treat CP. However, long term use of opioids can cause brain changes such as opioid-induced hyperalgesia that, over time, increase pain sensation. Also, opioids fail to treat complex psychological factors that worsen pain-related disability, including beliefs about and emotional responses to pain. Cognitive behavioral therapy (CBT) can be efficacious for CP. However, CBT generally does not focus on important factors needed for long-term functional improvement, including attainment of personal goals and the psychological flexibility to choose responses to pain. Acceptance and Commitment Therapy (ACT) has been recognized as an effective, non-pharmacologic treatment for a variety of CP conditions (Gutierrez et al., 2004). However, little is known about the neurologic mechanisms underlying ACT. We conducted an ACT intervention in women (n = 9) with chronic musculoskeletal pain. Functional magnetic resonance imaging (fMRI) data were collected pre- and post-ACT, and changes in functional connectivity (FC) were measured using Network-Based Statistics (NBS). Behavioral outcomes were measured using validated assessments such as the Acceptance and Action Questionnaire (AAQ-II), the Chronic Pain Acceptance Questionnaire (CPAQ), the Center for Epidemiologic Studies Depression Scale (CES-D), and the NIH Toolbox Neuro-QoLTM (Quality of Life in Neurological Disorders) scales. Results suggest that, following the 4-week ACT intervention, participants exhibited reductions in brain activation within and between key networks including self-reflection (default mode, DMN), emotion (salience, SN), and cognitive control (frontal parietal, FPN). These changes in connectivity strength were correlated with changes in behavioral outcomes including decreased depression and pain interference, and increased participation in social roles. This study is one of the first to demonstrate that improved function across the DMN, SN, and FPN may drive the positive outcomes associated with ACT. This study contributes to the emerging evidence supporting the use of neurophysiological indices to characterize treatment effects of alternative and complementary mind-body therapies.

Analgesic opioid use disorders in patients with chronic non-cancer pain: A holistic approach for tailored management

Chronic pain is a major public health issue that frequently leads to analgesic opioid prescriptions. These prescriptions could cause addiction issues in high-risk patients with associated comorbidities, especially those of a psychiatric, addictive, and social nature. Pain management in dependent patients is complex and is yet to be established. By combining the views of professionals from various specialties, we conducted an integrative review on this scope. This methodology synthesizes knowledge and results of significant practical studies to provide a narrative overview of the literature. The main results consisted in first proposing definitions that could allow shared vocabulary among health professionals regardless of their specialties. Next, a discussion was conducted around the main strategies for managing prescription opioid dependence, as well as pain in the context of opioid dependence and associated comorbidities. As a conclusion, we proposed to define the contours of holistic management by outlining the main guidelines for creating a multidisciplinary care framework for multi-comorbid patients with chronic pathologies.

Understanding the Impact of Sex and Gender in Osteoarthritis: Assessing Research Gaps and Unmet Needs

Osteoarthritis (OA) affects more than 300 million individuals globally, with higher prevalence in women than in men. In addition, OA affects women and men differently, with women demonstrating both increased disease severity and disability. The Society for Women's Health Research (SWHR) convened an interdisciplinary group of expert researchers and clinicians for a roundtable meeting to review the current state of the science on OA and to identify knowledge gaps in the scientific literature, especially as they relate to the topics of sex and gender. The current review summarizes discussions from the roundtable and prioritizes areas of need that warrant further attention in OA research, diagnosis, care, and education. Improvements in basic and clinical research, clinical practice, patient education, and policy are needed to allow for better understanding as to the pathogenesis of sex- and gender-related disparities in OA.

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.

Is pain catastrophizing associated with poor mobility performance and falls in older adults?

BACKGROUND

Pain catastrophizing has been associated with pain intensity and mobility limitations in adults, and may be associated with mobility problems among older adults with chronic pain. This study examined the associations between pain catastrophizing and pain characteristics, and physical performance in older people.

METHODS

The MOBILIZE Boston Study II (MBS) included 354 adults aged ≥70 years, living in the Boston area, originally enrolled in the MBS I from 2005-2008. Pain catastrophizing was measured using the 13-item Pain Catastrophizing Scale (PCS), with scores ranging from 13-65. Pain severity and pain interference were assessed by subscales of the Brief Pain Inventory. Pain distribution was classified as none, single site, and multisite. Mobility performance was assessed using the Short Physical Performance Battery (SPPB). Falls were assessed prospectively using monthly fall calendar postcards.

RESULTS

One-fourth of all participants (24 %) had high scores on the PCS (score>30). PCS was inversely associated with age and was greater among those with osteoarthritis, depression, or anxiety (p-value<0.05). PCS score was associated with global measures of pain including pain severity (p-value = 0.01), pain interference (p-value = 0.004) and multisite pain compared to no pain (p-value = 0.006). After adjusting for confounders, PCS was not associated with mobility and fall in this older population.

CONCLUSION

Although pain catastrophizing is prevalent in older adults with chronic pain, it was not associated with mobility or falls in older people. Further research is needed to determine possible long-term effects of pain catastrophizing on chronic pain and functioning in older adults.

Assessment of quality of life in individuals with chronic headache. Psychometric properties of the WHOQOL-BREF

BACKGROUND

The WHOQOL-BREF is a frequently used instrument for the assessment of health-related quality of life. Unlike other generic instruments used for the assessment of this construct, little is known about its properties in individuals with headache disorders. The present study examines the reliability and factorial validity of the WHOQOL-BREF in individuals with chronic headache residing in Austria.

METHODS

Data from a representative population-based survey on 963 individuals with chronic headache surveyed between 2013 and 2015 was used. The factorial validity was examined by means of confirmatory factor analysis. Differential item functioning related to sex was analyzed using multiple indicators multiple causes models.

RESULTS

Information on 239 men and 724 women with chronic headache was available. The four-factor, 24-item baseline model showed a moderate fit (RMSEA = 0.066; CFI = 0.868; TLI = 0.852; SRMR = 0.053), which improved significantly after the addition of six error covariances (RMSEA = 0.052; CFI = 0.920; TLI = 0.908; SRMR = 0.046). Sex-related differential item functioning was observed in two items of the environment factor, two items of the psychological health factor and two items of the physical health factor.

CONCLUSIONS

After some modifications to the measurement model, the WHOQOL-BREF shows a satisfactory fit among individuals with chronic headache in Austria. Because of these modifications and the questionnaire's susceptibility for differential item functioning, a latent variable framework should be employed for the analysis. Future studies need to confirm these results for other language regions and should also examine different subtypes of headache.

Non-Opioid Perioperative Pain Strategies for the Clinician: A Narrative Review

Alternative and non-opioid options for pain management are necessary in perioperative patient care. Opioids are no longer touted as cure-all medications, and furthermore, there have been tremendous advances in alternative therapies such as in interventional pain, physical therapy, exercise, and nutritional counseling that have proven benefits to combat pain. The center for disease control now strongly recommends the use of multimodal analgesia and multidisciplinary approaches based on the individual needs of patients: personalized medicine. In this manuscript, the specifics of non-opioid pharmacological and non-pharmacological analgesic approaches will be discussed as well as their possible indications and uses to reduce the need for excessive use of opioids for adequate pain control.

Continuous shortwave diathermy with exercise reduces pain and improves function in Lateral Epicondylitis more than sham diathermy: A randomized controlled trial

INTRODUCTION

Lateral epicondylitis or tennis elbow, causes significant pain and disability in the upper extremity. Conservative approaches include using thermal and electrical agents. The aim of this study was to explore the effectiveness of shortwave diathermy on pain, function and grip strength of patients with chronic lateral epicondylitis. A randomized placebo-controlled design with concealed allocation, assessor blinding and intention-to-treat analysis was conducted.

METHODS

Fifty patients suffering from lateral epicondylitis for more than 3 months, without any systemic diseases or history of other pathologies, were divided into two groups. In both groups, the patients were instructed to perform specific stretching and strengthening exercises. In addition, the patients in the experimental group, received 15 min of 40-60 W, continuous short wave diathermy while sham diathermy was applied for the control group. The primary outcome measure was pain and the secondary outcome measures were functional ability and pain free grip strength. Outcomes were assessed at the base line, after the 5th and the 10th session of treatment as well as after 3 months.

RESULTS

Mixed ANOVA analysis showed significant improvement in both groups. Meanwhile, there was a significant interaction effect of time and group on all outcome measures implying the greater improvement in pain, function and grip strength in the group receiving real diathermy.

CONCLUSIONS

Adding continuous short wave diathermy to a specific regimen of exercises, reduces pain and improves function in patients suffering from chronic lateral epicondylitis more than sham diathermy and exercise.

Your Performance Is My Concern: A Perspective-Taking Competition Task Affects ERPs to Opponent's Outcomes

Previous research has shown that people have more empathic responses to in-group members and more schadenfreude to out-group members. As a dimension of cognitive empathy, perspective-taking has been considered to be related to the enhancement of empathy. We tried to combine these effects through manipulation of a competitive task with opponents and an in-group partner and investigated the potential effect of in-group bias or the perspective-taking effect on outcome evaluation. We hypothesized that the neural activities would provide evidence of in-group bias. We tested it with a simple gambling observation task and recorded subjects' electroencephalographic (EEG) signals. Our results showed that the opponent's loss evoked larger feedback-related negativity (FRN) and smaller P300 activity than the partner's loss condition, and there was a win vs. loss differential effect in P300 for the opponent only. The principal component analysis (PCA) replicated the loss vs. win P300 effect to opponent's performance. Moreover, the correlation between the inclusion of the other in the self (IOS) scores and FRN suggests perspective-taking may induce greater monitoring to opponent's performance, which increases the win vs. loss differentiation brain response to the out-group agent. Our results thus provide evidence for the enhanced attention toward out-group individuals after competition manipulation, as well as the motivation significance account of FRN.
