Self-efficacy, fear avoidance, and pain intensity as predictors of disability in subacute and chronic musculoskeletal pain patients in primary health care

Cross-Cultural Adaptation, Translation, and Validation of Pain Self-Efficacy Questionnaire in Hindi Language in Patients With Chronic Neck Pain

STUDY DESIGN

Translation and psychometric testing.

OBJECTIVES

The objective of this study was to translate and culturally adapt the Pain Self-Efficacy Questionnaire (PSEQ) into Hindi (PSEQ-H), the local language of India, and assess its psychometric properties.

BACKGROUND

The PSEQ is a commonly used outcome measure in patients with pain and related psychosocial aspects too. The PSEQ invites participants to consider their pain while assessing their self-efficacy views. Because about half of India's population understands Hindi, there is a need to translate the PSEQ into Hindi for patient convenience and better comprehension, as well as for research purposes.

MATERIALS AND METHODS

The PSEQ has been translated and culturally adapted into Hindi. A total of 120 patients with chronic neck pain were recruited. The PSEQ-H's content validity, construct validity, internal consistency, test-retest reliability, and responsiveness were all assessed. To determine test-retest reliability, the intraclass correlation coefficient was calculated. Cronbach alpha was used to determine internal consistency. Criterion validity was assessed using the neck disability index, NRS, and anxiety and depression measures. The area under the curve and the change cut-point were determined using the receiver operating characteristic curve analysis.

RESULTS

The PSEQ-H exhibited strong test-retest reliability (intraclass correlation coefficient = 0.90) and good internal consistency (Cronbach alpha = 0.88). Factor analysis confirmed a one-factor structure for the PSEQ-H. Furthermore, the PSEQ-H demonstrated a moderate correlation with the neck disability index, numerical pain rating scale, anxiety, and depression scales. A change detection threshold of 8.3 was established.

CONCLUSIONS

The PSEQ-H is a reliable and valid measure for use in research and clinical purposes in the Indian population with chronic neck pain.

Implementing and Evaluating a Mobile Phone-Supported and Family-Centered Rehabilitation Program for People With Stroke in Uganda (F@ce 2.0): Protocol for a Randomized Controlled Trial

BACKGROUND

Stroke is a global societal challenge. Annually, 13 million people experience stroke, and the prevalence of stroke is increasing in low-income countries; hence, accessible rehabilitation needs to be developed. Information and communication technology can help by providing access to rehabilitation support through information, self-evaluation, and self-management of rehabilitation. The F@ce 2.0 rehabilitation program provides support in goal-setting and problem-solving strategies through phone calls from the interventionist twice a week and daily SMS text message reminders over 8 weeks to improve performance in valued activities in everyday life. Our hypothesis is that F@ce 2.0 will increase functioning in daily activities and participation in everyday life as well as improve performance and satisfaction in valued daily activities and self-efficacy (ie, confidence in own ability to perform activities) among people living with the consequences of stroke.

OBJECTIVE

This study aims to implement F@ce 2.0, a mobile phone-supported and family-centered rehabilitation program, and evaluate its effects on performance in daily activities and participation in everyday life in comparison to ordinary rehabilitation among persons with stroke and their family members in Uganda. An additional aim is to explore experiences of participating in F@ce 2.0 and plausible mechanisms of impact that might explain the potential effects of F@ce 2.0.

METHODS

A randomized controlled trial will be conducted to compare the outcomes of the F@ce 2.0 group and a control group receiving ordinary rehabilitation. Health care professionals will recruit 90 clients from both urban and rural areas. The primary outcomes for persons with stroke are perceived performance in daily activities assessed using the Canadian Occupational Performance Measure and self-efficacy assessed using the Self-Efficacy Scale; for family members, the primary outcome is caregiver burden evaluated using the Caregiver Burden Scale. Descriptive statistics will be used to present characteristics and outcomes at 3 and 6 months. All statistical analyses comparing the outcomes at the different time points between the F@ce 2.0 and control groups will be performed using intention-to-treat analysis. Qualitative interviews will be used to explore the experiences of persons with stroke and their family members participating in F@ce 2.0, using a grounded theory approach to data collection and analysis. A process evaluation will be conducted using a single-case study design with mixed methods to explore the implementation process.

RESULTS

Recruitment and data collection in the randomized controlled trial were initiated in January 2022 and have been completed. The intervention has been provided to 51 participants in the intervention group. Interviews of persons with stroke, family members, and health care professionals have been conducted. Data analysis will be performed during autumn 2024 and spring 2025.

CONCLUSIONS

This study will provide evidence of the plausible effects of F@ce 2.0 and the process of implementing the program in low-income countries.

Measurement Properties of Two Questionnaires Assessing Fear-Avoidance in Patients With Chronic Low Back Pain

The Fear-Avoidance Components Scale (FACS) and the Fear of Daily Activities Questionnaire (FDAQ) assess fear-avoidance model components. However, the questionnaires are not available in Brazilian Portuguese. This study aimed to translate the original English FACS and FDAQ into Brazilian (Br) Portuguese and assess their measurement properties in patients with Chronic Low Back Pain (CLBP). One hundred thirty volunteers with CLBP participated in this study. Structural validity, internal consistency, test-retest reliability, and hypothesis testing for construct validity were analyzed. Results indicated a 2-factor solution for the FACS-Br, while the FDAQ-Br had a one-factor solution. Internal consistency showed acceptable Cronbach's alpha (alpha >.8). Suitable reliability was found for the FDAQ-Br (Intraclass Correlation Coefficient [ICC] = .98). For both FACS-Br factors, suitable reliability was found as well (ICC = .95 and .94). Hypothesis testing for construct validity confirmed more than 75% of the hypotheses proposed a priori for the FACS maladaptive pain/movement-related beliefs domain and the FDAQ-Br. In conclusion, the FACS-Br and FDAQ-Br demonstrated acceptable reliability, internal consistency, and structural validity measurement properties and their correlation (r < .50) suggests that the tools are not interchangeable measures.

The Swedish Stroke Self-Efficacy Questionnaire: translation and cross-cultural adaptation

OBJECTIVE

To translate and cross-culturally adapt the Stroke Self-Efficacy Questionnaire (SSEQ) from English to Swedish and to evaluate psychometric properties of the questionnaire.

METHODS

A cross-sectional study design, where the translation followed a process including initial translation, synthesis, backward translation, expert committee, and pretest. Content validity was assessed using Content validity index (CVI). Psychometric assessments included floor-ceiling effects and internal consistency.

RESULTS

Language and cultural congruence were achieved, and content validity index scores were high (0.923-1). The psychometric evaluations provided acceptable outcomes concerning internal consistency, with Cronbach's alpha scores for the total scale (0.902), the activities subscale (0.861) and the self-management subscale (0.818) respectively. Ceiling effects were evident, but no floor effects.

CONCLUSION

This study found the Swedish version of the SSEQ promising as a tool for assessment of self-efficacy in a Swedish stroke care setting, although further psychometric assessments are recommended in future studies.

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

Objective

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

Methods

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

Conclusion

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

Prevention of sickness absence through early identification and rehabilitation of at-risk patients with musculoskeletal disorders (PREVSAM): short term effects of a randomised controlled trial in primary care

PURPOSE

To evaluate short-term effects of the PREVention of Sickness Absence for Musculoskeletal disorders (PREVSAM) model on sickness absence and patient-reported health outcomes.

METHODS

Patients with musculoskeletal disorders were randomised to rehabilitation according to PREVSAM or treatment as usual (TAU) in primary care. Sickness absence and patient-reported health outcomes were evaluated after three months in 254 participants.

RESULTS

The proportion of participants remaining in full- or part-time work were 86% in PREVSAM vs 78% in TAU (p = 0.097). The PREVSAM group had approximately four fewer sickness benefit days during three months from baseline (p range 0.078-0.126). No statistically significant difference was found in self-reported sickness absence days (PREVSAM 12.4 vs TAU 14.5; p = 0.634), nor were statistically significant differences between groups found in patient-reported health outcomes. Both groups showed significant improvements from baseline to three months, except for self-efficacy, and only the PREVSAM group showed significantly reduced depression symptoms.

CONCLUSIONS

The findings suggest that for sickness absence, the PREVSAM model may have an advantage over TAU, although the difference did not reach statistical significance at the p < 0.05 level, and similar positive effects on patient-reported health outcomes were found in both groups. Long-term effects must be evaluated before firm conclusions can be drawn.

The Swedish version of the pain self-efficacy questionnaire short form, PSEQ-2SV: Cultural adaptation and psychometric evaluation in a population of patients with musculoskeletal disorders

OBJECTIVES

Measuring pain self-efficacy is suggested as relevant in patients with musculoskeletal disorders (MSDs) in a primary care setting. However, there is no pain self-efficacy questionnaire (PSEQ) available in Swedish. The aim of this study was to translate and culturally adapt PSEQ-2 to Swedish and evaluate reliability and validity in a population of patients with MSDs.

METHODS

A translation and cultural adaptation together with psychometric evaluation of reliability and validity were performed according to guidelines with three groups of participants with MSDs. First, a convenient sample of 25 individuals were interviewed in the translation process. Next, 61 participants completed the test-retest survey via social media or QR codes in waiting rooms in rehabilitation clinics. Finally, to evaluate construct validity questionnaires were obtained from 132 participants with MSDs in an ongoing randomized controlled trial.

RESULTS

The Swedish version of PSEQ-2 showed adequate face and content validity. The results of 0.805 on Cohen's weighted kappa indicate that the reliability of PSEQ-2SV in a group of adults with MSDs is on the border between substantial and almost perfect. The point estimate regarding relative rank variance, measuring the individual variation within the group, and relative concentration, the systematic change in how the assessments are concentrated on the scale's categories, shows minor systematic differences and some random differences not neglectable. The construct validity of pre-defined hypotheses was met to some degree.

CONCLUSION

The PSEQ-2SV has been accurately linguistically translated and tested for reliability and validity, in a population of MSDs, and is deemed to be able to be used in the clinic and in research. As there were some concerns regarding measurement error and systematic bias, more research could be of value.

Pain Control Beliefs Predict Premature Withdrawal From the Labor Market in Workers With Persistent Pain: Prospective Cohort Study With 11-Year Register Follow-up

While a range of work-related psychosocial factors has been associated with various pain disorders and early retirement, less is known about pain cognitions and their influence on premature exit from the labor market. Therefore, as a primary objective, this study investigates associations between pain control beliefs and risk of disability pension among Danish eldercare workers. In 2005, 2257 female eldercare workers with low-back and/or neck/shoulder pain>90 days within the previous 12 months, replied to a survey and were followed for 11 years in a national register of social transfer payments. Using Cox regression, we estimated the risk of disability pension during follow-up from experiencing different levels of "pain control" and "pain influence," controlling for pain intensity and other relevant confounders. In the fully adjusted model for pain control with "high" as reference, hazard ratios of 1.30 (95% CI 1.03-1.64) and 2.09 (95% CI 1.45-3.01) are observed for "moderate" and "low," respectively, while the metric of pain influence shows hazard ratios of 1.43 (95% CI 1.11-1.87) and 2.10 (1.53-2.89), respectively. Pain control beliefs are associated with disability pension among eldercare workers with persistent pain. These results highlight the importance of evaluating not only bodily manifestations of pain, but also individual pain-related cognitions that may influence the experience of pain. PERSPECTIVE: This article addresses the complex experience of pain within an organizational context. We introduce the metrics of "pain control" and "pain influence" among workers with persistent pain, showing that the psychometric properties of these measures are prospectively associated with premature exit from the labor market.

Does coping with pain help the elderly with cardiovascular disease? The association of sense of coherence, spiritual well-being and self-compassion with quality of life through the mediating role of pain self-efficacy

BACKGROUND

Population ageing is considered one of the biggest challenges facing the world, and the status of the elderly in society and their quality of life (QOL) have proved to be a concern in professional and scientific research circles. As a result, the current study sought to investigate the role of pain self-efficacy (PSE) as a moderator in the relationship between sense of coherence (SOC), spiritual well-being, and self-compassion with QOL in Iranian elderly with cardiovascular disease (CVD).

METHOD

This was a correlational study of the path analysis type. The statistical population included all elderly people with CVD who were at least 60 years of age in Kermanshah Province, Iran, in 2022, of whom 298 (181 men and 117 women) were selected using convenience sampling and according to the inclusion and exclusion criteria. The participants answered questionnaires from the World Health Organization on QOL, Paloutzian and Ellison's spiritual well-being, Nicholas's PSE, Antonovsky's SOC, and Raes et al.'s self-compassion.

RESULTS

The results of path analysis demonstrated that the hypothesized model of this study has a good fit in the studied sample. There were significant paths between SOC (β = 0.39), spiritual well-being (β = 0.13) and self-compassion (β = 0.44) with PSE. Although there were significant paths between SOC (β = 0.16) and self-compassion (β = 0.31) with QOL, there was no significant path between spiritual well-being and QOL (β = 0.06). Besides, there was a significant path between PSE and QOL (β = 0.35). Finally, PSE was found to mediate the relationship of SOC, spiritual well-being and self-compassion with QOL.

CONCLUSION

The results may provide psychotherapists and counselors working in this field of inquiry with advantageous information to choose or create a useful therapeutic method to work with the elderly with CVD. Meanwhile, other researchers are suggested to examine other variables which may serve a mediating role in the mentioned model.

A more than 20-year follow-up of pain and disability after anterior cervical decompression and fusion surgery for degenerative disc disease and comparisons between two surgical techniques

BACKGROUND

Follow-ups more than 20 years after neck surgery are extremely rare. No previous randomized studies have investigated differences in pain and disability more than 20 years after ACDF surgery using different techniques. The purpose of this study was to describe pain and functioning more than 20 years after anterior cervical decompression and fusion surgery, and to compare outcomes between the Cloward Procedure and the carbon fiber fusion cage (CIFC).

METHODS

This study is a 20 to 24-year follow-up of a randomized controlled trial. Questionnaires were sent to 64 individuals, at least 20 years after ACDF due to cervical radiculopathy. Fifty individuals (mean age 69, 60% women, 55% CIFC) completed questionnaires. Mean time since surgery was 22.4 years (range 20,5-24). Primary outcomes were neck pain and neck disability index (NDI). Secondary outcomes were frequency and intensity of neck and arm pain, headache, dizziness, self-efficacy, health related quality of life or global outcome. Clinically relevant improvements were defined as 30 mm decrease in pain and a decrease in disability of 20 percentage units. Between-group differences over time were analyzed with mixed design ANOVA and relationships between main outcomes and psychosocial factors were analyzed by Spearman´s rho.

RESULTS

Neck pain and NDI score significantly improved over time (p  <  .001), with no group differences in primary or secondary outcomes. Eighty-eight per cent of participants experienced improvements or full recovery, 71% (pain) and 41% (NDI) had clinically relevant improvements. Pain and NDI were correlated with lower self-efficacy and quality of life.

CONCLUSION

The results from this study do not support the idea that fusion technique affects long-term outcome of ACDF. Pain and disability improved substantially over time, irrespective of surgical technique. However, the majority of participants reported residual disability not to a negligible extent. Pain and disability were correlated to lower self-efficacy and quality of life.

Construct validity of the Mini-BESTest in individuals with chronic pain in specialized pain care

BACKGROUND

Balance assessment scales are important clinical tests to identify balance impairments. Chronic pain (> 3 months) is associated with impaired dynamic balance; however, very few balance assessment scales are psychometrically evaluated for the population. The purpose of this study was to evaluate the construct validity and internal consistency of the Mini-BESTest for individuals with chronic pain in specialized pain care.

METHODS

In this cross-sectional study, 180 individuals with chronic pain (> 3 months) were assessed with the Mini-BESTest and included in the analyses. For construct validity, five alternative factor structures were evaluated using a confirmatory factor analysis. In addition, we tested the a priori hypotheses about convergent validity with the 10-meter walk test, and divergent validity with the Brief Pain Inventory (BPI): pain intensity, the Tampa Scale of Kinesiophobia-11 (TSK-11), and the Pain Catastrophizing Scale (PCS-SW). Internal consistency was evaluated for the model with the best fit.

RESULTS

A one-factor model with added covariance via the modification indices showed adequate fit indices. In line with our hypotheses, Mini-BESTest showed convergent validity (r_s = > 0.70) with the 10-meter walk test, and divergent validity (r_s = < 0.50) with BPI pain intensity, TSK-11, and PCS-SW. Internal consistency for the one-factor model was good (α = 0.92).

CONCLUSIONS

Our study supported the construct validity and internal consistency of the Mini-BESTest for measuring balance in individuals with chronic pain, who were referred to specialized pain care. The one-factor model showed an adequate fit. In comparison, models with subscales did not reach convergence, or showed high correlations between subscales, implying that Mini-BESTest is measuring one construct in this sample. We, therefore, propose using the total score, instead of subscale scores, for individuals with chronic pain. However, further studies are necessary to establish the reliability of the Mini-BESTest in the population.

Reliability and aspects of validity of the Swedish version of self-efficacy for exercise scale for patients with chronic pain

BACKGROUND

Active, specific, and professionally led physical exercise is an effective treatment for chronic pain, and self-efficacy is correlated to positive treatment outcomes. At present, there is limited knowledge of self-efficacy for exercise in patients with chronic pain.

PURPOSE

To evaluate the reliability and aspects of validity of the Swedish version of the Self-Efficacy for Exercise Scale (SEE-SV) in patients with chronic pain.

METHODS

Patients with chronic pain were recruited from a specialist clinic. The Swedish version of the SEE was used. Reliability was evaluated through internal consistency, test-retest, and measurement error (standard error of measurement, SEM and smallest detectable change, SDC). Construct validity was calculated using the correlation between the SEE-SV and other well-established evaluation instruments. Content validity was evaluated both from a patient and a health-care professional perspective.

RESULTS

In total, 44 patients, 31 women and 13 men (mean age 40 years), participated in the study. The SEE-SV had good test-retest reliability (intra-class correlation coefficient (ICC) = 0.95) and internal consistency (Cronbach's alpha = 0.97). Regarding measurement error, SEM was 4.9 and SDC 13.5. Moderate correlation was seen between SEE-SV and a pain-specific self-efficacy questionnaire (rs = 0.52). The majority of patients and health-care professionals considered the SEE-SV to be relevant and easy to understand.

CONCLUSION

The SEE-SV showed a good internal consistency, item-to-total correlation, and test-retest reliability (ICC). A relatively high SDC indicates an individual variability of the test results. The content validity was satisfactory. Regarding the construct validity, further studies are needed.

Physical activity, self-efficacy and quality of life in patients with chronic pain, assessed during and 1 year after physiotherapy rehabilitation - a prospective follow-up study

PURPOSE

The aim of this prospective cohort study was to evaluate the level of physical activity, self-efficacy and health-related quality of life in patients with chronic pain, at baseline and one year after physiotherapy rehabilitation at a specialist pain clinic.

MATERIALS AND METHODS

All patients who underwent rehabilitation at the physiotherapy unit at the Pain Centre at Sahlgrenska University Hospital/Östra in Gothenburg during a nine-month period were asked to participate in the study. The participants were evaluated regarding self-efficacy, health-related quality of life (HRQoL) and physical activity during physiotherapy treatment and one year later. Physical activity was measured both subjectively (self-reported physical activity) and objectively (accelerometer).

RESULTS

Out of 42 patients who participated in the baseline evaluation, 28 (19 women and nine men) were included in the one-year follow-up. The patients had increased levels of vigorous physical activity at one-year follow-up, without deterioration of pain. There were no significant changes regarding self-efficacy and HRQoL. Levels of physical activity and perceived physical function may be associated to levels of physical activity 1 year after rehabilitation.

CONCLUSION

Patients with chronic pain can increase their level of vigorous physical activity after a period of rehabilitation without deterioration of pain.IMPLICATIONS FOR REHABILIATIONPhysical activity is an important part of rehabilitation for chronic pain patients, but many patients expect more pain after exercise, which they fear may affect performance and maintenance of physical activity.Patients with chronic pain at a specialist clinic increased their level of vigorous physical activity one year after physiotherapist led rehabilitation without deterioration of pain.Levels of physical activity and perceived physical function during rehabilitation may predict levels of physical activity 1 year after rehabilitation.Physiotherapist led rehabilitation seems to be beneficial for long-term improved physical activity in patients with chronic pain.

Reliability and validity of the Japanese version of Pain Disability Index

This study evaluated the reliability and validity of a Japanese version of Pain Disability Index (PDI). Analyses were conducted on a 7-item version (PDI-J) and a 5-item (PDI-5-J version of the PDI). Using a web-based survey system, we recruited 300 individuals with chronic low back pain (lasting ≥3 months) and 300 individuals with chronic daily headache (lasting ≥15 days per month for 3 months) aged 20–64 years. Analyses revealed a one-factor with goodness-of-fit indices assessed by confirmatory factor analysis. For concurrent validity, we calculated Pearson’s correlation coefficients among the PDI-J, PDI-5-J, Pain Disability Assessment Scale, Pain numerical rating scale, and revised version of Short-Form McGill Pain Questionnaire. Internal consistency was evaluated by Cronbach’s α, and test–retest reliability was assessed with intraclass correlations (ICCs) in 100 of 600 participants a week after the first response. Both Japanese adaptations of the PDI demonstrated good concurrent validity and reliability (Cronbach’s α was 0.89 for PDI-J in chronic low back pain or chronic daily headache, and 0.94 and 0.93 for PDI-5-J in chronic low back pain and chronic daily headache, respectively). The PDI-J and PDI-5-J showed were highly correlated (r = 0.98). ICCs were 0.67 and 0.59 for the PDI-J and 0.59 and 0.63 for the PDI-5-J in chronic low back pain and chronic daily headache, respectively. In conclusion, these two PDI versions can be potentially used for evaluating pain-related interference with daily activities among the Japanese general population.

Study protocol of a non-randomised controlled trial evaluating the effectiveness of the F@ce 2.0 programme: a person-centred, ICT-supported and interdisciplinary rehabilitation intervention after stroke

INTRODUCTION

Knowledge is missing on use of information and communication technology (ICT), for example, mobile phones/tablets in rehabilitation after stroke. F@ce 2.0 is a person-centred, interdisciplinary intervention supported by ICT. The components of F@ce 2.0 intend to increase performance in daily activities and participation in everyday life for patients with stroke and their significant others. Based on previous feasibility studies, a full-scale evaluation is planned in Sweden. The aim is to implement and evaluate F@ce 2.0, regarding performance of daily activities and participation in everyday life, in comparison with ordinary rehabilitation among persons who have had stroke and significant others. Second, to increase knowledge about how the programme leads to a potential change by studying the implementation process and mechanisms of impact.

METHODS AND ANALYSIS

Twelve rehabilitation teams (intervention n=7; control n=5) will recruit patients (n=160) who receive rehabilitation at home after stroke and their significant others. F@ce 2.0 is an 8-week intervention where patients, together with the team, formulate three activity goals regarding what they need and want to do in daily lives. The patients will receive short messages service (SMS) each morning reminding about goals, and in the evening to rate their performance during the day. Primary outcomes for patients: self-efficacy measured by the Self-Efficacy Scale; perceived performance in daily activities measured by the Canadian Occupational Performance Measure. Significant others: perceived caregiver burden measured by Caregiver Burden Scale. Qualitative interviews with team members delivering, patients receiving intervention and significant others will explore experiences of F@ce 2.0. A process evaluation applying a case-study design using mixed methods will be conducted.

ETHICS AND DISSEMINATION

Approved by the Swedish Ethical Review Authority, Stockholm. Knowledge will be created for using ICT for rehabilitation of people after stroke in self-selected activities. Dissemination will include peer-reviewed publications, presentations at conferences, and information to stakeholders.

Kinesiophobia and associated factors among patients with chronic non-specific low back pain

PURPOSE

This study determined the association between kinesiophobia and age, body mass index, highest educational status, self-efficacy, pain intensity, and disability in chronic non-specific low back pain (CNSLBP) patients. Predictors of kinesiophobia were also assessed.

METHODS

This cross-sectional design utilised 224 CNSLBP patients in tertiary hospitals in Nigeria. The Tampa Scale of Kinesiophobia, Oswestry Disability Index, Pain Self-Efficacy Questionnaire, and Numerical Pain Rating Scale were used to assess kinesiophobia, disability, self-efficacy, and pain intensity respectively. Spearman's correlation and multiple regression analysis determined the association between the variables of interest and the predictors of kinesiophobia, respectively.

RESULTS

Most of the participants reported a high level of kinesiophobia (92%), low level of self-efficacy (68.8%), moderate pain intensity (58.0%), and moderate disability (57.1%). A significant positive weak correlation was observed between kinesiophobia and pain intensity (r = 0.138, p = 0.040). Gender, self-efficacy, pain intensity, and disability significantly predicted the extent of kinesiophobia (p < 0.05).

CONCLUSION

The increased levels of kinesiophobia are a cause for concern and highlight the need for kinesiophobia and related factors to be closely monitored and incorporated into preventive and curative rehabilitation programmes for CNSLBP patients to minimise the negative impact on rehabilitation outcomes.Implications for RehabilitationPatients with chronic non-specific low back pain (CNSLBP) have high levels of kinesiophobia, which could predispose them to avoidance behaviours, physical inactivity, and deterioration of health, all of which, if not addressed, may result in poor rehabilitation outcomes, setting off a viscious cycle.Regular kinesiophobia assessments could indicate areas of rehabilitation concern, allowing health care providers to better target rehabilitation programs and improve rehabilitation outcomes.Pain severity, self-efficacy, and disability should be frequently assessed and included when planning rehabilitation programs, to reduce the detrimental impact on kinesiophobia.In patients with CNSLBP, graded exposure therapy to movement is necessary to prevent and reduce kinesiophobia, thereby increasing compliance during rehabilitation programs.

Validation of a Model Predicting That Physical Activities Improve Health-Related Quality of Life in Older Japanese Adults with Pain, Dysesthesia, and Kinesiophobia after Lumbar Surgery: Structural Equation Modeling

Objectives. This study assessed the validity of a hypothesized model predicting that physical activity improves health-related quality of life (HRQOL) in older Japanese adults with pain, dysesthesia, and kinesiophobia following lumbar surgery. Methods. We included 431 elderly patients who underwent surgery for lumbar spinal stenosis at two hospitals. The frequency of physical activity, pain, dysesthesia, kinesiophobia (somatic focus and activity avoidance), and HRQOL were investigated using a questionnaire. Missing values were complemented by the stochastic regression imputation. We constructed the following model. (i) physical activity affects pain, dysesthesia, and kinesiophobia. (ii) pain, dysesthesia, and kinesiophobia separately affect HRQOL. This hypothetical model was tested by structural equation modeling. The model was improved based on a modified index. Results. Of the 431 respondents, 297 (median age 72 years, range 65–91 years; 158 men and 139 women) were analyzed (68.9%). The fit of the model improved based on the modification index and was acceptable comparative fit index, 0.948; Tucker–Lewis index, 0.919; root mean square error of approximation, 0.048 (90% confidence interval, 0.026–0.069), and standardized root mean square residual (0.046). The paths by which physical activities reduced pain or dysesthesia (standardized pass coefficients, −0.406) and somatic focus (−0.301) and consequently improved HRQOL were significant (pain/dysesthesia, −0.684; somatic focus, −0.218). Discussion. Our hypothesized model predicting that physical activity improves HRQOL in terms of pain, dysesthesia, and kinesiophobia in older Japanese adults after lumbar surgery was validated using cross-sectional data. Interventional studies on physical activity based on this model are required to establish the model.

Efficacy of the Gelstix nucleus augmentation device for the treatment of chronic discogenic low back pain: protocol for a randomised, sham-controlled, double-blind, multicentre trial

INTRODUCTION

Discogenic pain is the cause of pain in 26%-40% of patients with for low back pain. Consensus about treatment of chronic discogenic low back pain is lacking and most treatment alternatives are supported by limited evidence. The percutaneous implantation of hydrogels into the nucleus pulposus represents a promising regenerative intradiscal therapy. The hydrogel 'GelStix' is composed primarily of hydrolyzed polyacrylonitrile and acts as a reservoir of hydration, producing increased pressure and improved pH balance, potentially leading to disc preservation. We hypothesise that treatment with GelStix will lead to greater reduction in pain intensity at 6 months post-treatment compared with patients receiving sham treatment.

METHODS AND ANALYSIS

This is a parallel group, randomised sham-controlled double-blind, multicentre trial to assess whether the GelStix device is superior to sham in reducing pain intensity in patients with chronic discogenic low back pain. The study will be conducted in two regional hospitals in Europe. Seventy-two participants will be randomised in a 1:1 ratio. The primary outcome will be the change in pain intensity between preoperative baseline and at 6 months postintervention. Secondary outcomes were disability, quality of life, the patient's global impression of change scale, the use of pain medication and the disc degeneration process assessed by means of MRI. For change in pain intensity, disability, health-related quality of life and disc height, mean values will be compared between groups using linear regression analysis, adjusted for treatment centre.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the Ethics Committee of the Canton Ticino, Switzerland (CE2982) and by the Medical Ethical Committee Arnhem-Nijmegen, the Netherlands (2016-2944). All patients that agree to participate will be asked to sign an informed consent form. Results will be disseminated through international publications in peer-reviewed journals, in addition to international conference presentations.

Pain self‐management intervention supports successful attainment of self‐selected rehabilitation goals—secondary analysis of a randomized controlled trial

Objectives

(i) Describe patients' self‐selected activity‐related rehabilitation goals, and (ii) compare attainment of these rehabilitation goals among people with persistent tension‐type neck pain receiving a group‐based pain and stress self‐management intervention (PASS) or individual physiotherapy (IPT).

Methods

Before intervention and random allocation to PASS or IPT, 156 people (PASS n = 77, IPT n = 79), listed three self‐selected activity‐related rehabilitation goals by use of the Patient Goal Priority Questionnaire (PGPQ). For each activity goal, participants rated limitations in activity performance, self‐efficacy and fear of activity performance, readiness to change to improve performance, and expectations of future activity performance. At follow‐ups (10 weeks, 20 weeks, 1 year and 2 years after inclusion), participants also responded to a question on changes made to improve activity performance. Mann–Whitney U test was used to evaluate between‐group differences.

Results

There were between‐group differences in favour of PASS in the attainment of self‐selected rehabilitation goals with regard to activity limitations and satisfaction with activity performance at all follow‐ups.

Conclusions

PASS was more successful than IPT for the attainment of self‐selected rehabilitation goals, improvements in activity limitations and satisfaction with activity performance as measured by PGPQ. The PASS programme emphasized the importance of applying active pain‐ and stress‐coping techniques in personal ‘risk situations’ for pain flare‐ups, which appear to support people with persistent tension‐type neck pain to make changes in their lives to improve activity performance.

Patient or Public Contribution

Patient engagement in rehabilitation by self‐selected goals was investigated, but patients were not involved in the design or conduct of the study.

Cross-cultural adaptation, reliability and validity of the Marathi versions of the Back Beliefs Questionnaire and Pain Self-Efficacy Questionnaire in people living with chronic low back pain

PURPOSE

To translate and cross-culturally adapt the Back Beliefs Questionnaire (BBQ) and Pain Self-Efficacy Questionnaire (PSEQ) into Marathi, and to evaluate their clinimetric properties in a native Marathi speaking population with chronic low back pain.

MATERIAL AND METHODS

The BBQ and PSEQ were translated into Marathi using international published guidelines. Fifty native Marathi speakers were recruited. Reliability (n = 43) was evaluated in terms of internal consistency (Cronbach α) and test-retest reliability [intra class correlation coefficient, ICC (2, 1)] and 95% confidence interval (CI). Convergent validity (n = 50) was assessed by correlating the Marathi versions of BBQ and PSEQ with the Marathi version of Roland Morris Disability Questionnaire (RMDQ).

RESULTS

Internal consistency of BBQ (Cronbach α  =  0.67) was good and that for PSEQ (Cronbach α  =  0.93) was high. Test-retest reliability for BBQ (ICC =  0.80; 95% CI: 0.66 to 0.89) was good and PSEQ (ICC = 0.85; 95% CI: 0.74 to 0.92) was excellent. A significant, low negative correlation was found between RMDQ and BBQ scores (r = -0.298; p = 0.036) and PSEQ (r = -0.28; p = 0.049).

CONCLUSIONS

The BBQ and PSEQ were successfully cross-culturally adapted into Marathi. Clinimetric evaluation of these questionnaires in a sample of native Marathi speaking populations with chronic low back pain demonstrated good acceptability, acceptable internal consistency, and high test-retest reliability.Implications for rehabilitationThe Back Beliefs Questionnaire (BBQ) and Pain Self Efficacy Questionnaire (PSEQ) were successfully cross-culturally adapted into Marathi.The Marathi versions of BBQ and PSEQ have good acceptability, acceptable internal consistency, and high test-retest reliability.They can be used by clinicians and researchers to evaluate beliefs about back pain and pain self-efficacy in Marathi speaking patients with chronic low back pain.

Behavioral Medicine Physiotherapy in the Context of Return to Work for Chronic Pain: A Single-Case Experimental Design Study

Effective interventions are needed for return-to-work (RTW) for individuals with chronic pain on long-term sick leave. In this study, a behavioral medicine physiotherapy protocol was systematically replicated and added to workplace components. The intervention was evaluated for fidelity and effects on target activities and work ability. A single-case experimental design was used with five participants. Daily and weekly ratings of personalized target activities at work as well as work ability were carried out throughout the study period of 26-28 weeks. Effects of the behavioral medicine physiotherapy intervention were evaluated for each individual using visual analysis of displayed graphs and quantitative non-overlap methods. Goal achievement for target activities was reviewed. Three participants completed the intervention. The results indicated an effect from the behavioral medicine physiotherapy intervention on task-specific self-efficacy for target activities, but no consistent effect on experience of target activities or work ability. All three participants had increased function in target activities in line with pre-defined goals. Fidelity to the intervention manual was good. Behavioral medicine physiotherapy can be successfully adapted to work disability and was here replicated in an RTW context for individuals with chronic pain. The intervention protocol should be further evaluated in large-scale studies.

The relationship between psychosocial factors and reported disability: the role of pain self-efficacy

BACKGROUND

Chronic pain and the accompanying level of disability is a healthcare crisis that reaches epidemic proportions and is now considered a world level crisis. Chronic non-specific low back pain (CNLBP) contributes a significant proportion to the chronic pain population. CNLBP occurs with overlapping psychosocial factors. This study was design to investigate specific psychosocial factors and their influence on reported disability in a population with CNLBP.

METHODS

The specific psychosocial factors examined included fear, catastrophizing, depression, and pain self-efficacy. This cross-sectional correlational study investigated the mediating role between pain self-efficacy, the specific psychosocial factors, and reported disability. The study recruited 61 female and 29 male participants from physical therapy clinics. The participants were between 20-to-60 years of age and diagnosed with CNLBP. All participants completed the Fear Avoidance Belief Questionnaire, The Pain Catastrophizing Scale, The Patient Health Questionnaire-9, The Pain Self-Efficacy Questionnaire, and The Lumbar Oswestry Disability Index. The battery of questionnaires measured fear of physical activity, pain catastrophizing, depression, pain self-efficacy, and reported disability. Multivariate regression and mediation analyses was used to analyse the data.

RESULTS

The principal finding was a strong inverse relationship between pain self-efficacy and reported disability with a p-value < 0.001. Further, pain self-efficacy was considered a statistical mediator with consistent p-value < 0.001 for the specific psychosocial factors investigated within this data set. Pain self-efficacy was considered to have a mediating role between reported fear of physical activity and disability, reported pain catastrophizing and disability, and reported depression and disability. Additionally, age and reported pain levels proved to be statistically significant. Adjustments for age and pain level did not alter the role of pain self-efficacy.

CONCLUSION

The results identified a mediating role for pain self-efficacy between the specific psychosocial factors (fear, catastrophizing, and depression) and reported disability. Pain self-efficacy plays a more significant role in the relationships between these specific psychosocial factors and reported disability with CNLBP than previously considered.

The importance of suicide risk assessment in patients affected by neurofibromatosis

OBJECTIVE

Neurofibromatosis 1 (NF1) is a chronic medical disease that often presents with psychiatric disorders. We investigated suicidal ideation in NF1 patients compared to healthy controls. We also evaluated whether hopelessness, depressive symptoms and perceived disability may mediate suicidal ideation in patients with NF1.

METHODS

We enrolled 60 patients with NF1 and 50 healthy controls with no history of NF1. Patients underwent a full psychiatric evaluation. Psychiatric diagnosis was made according to Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) criteria. Patients and controls underwent a series of psychometric measures, namely the Columbia Suicide Severity Rating Scale, the Beck Hopelessness Scale, the Italian Perceived Disability Scale and the Beck Depression Inventory.

RESULTS

Suicidal ideation was significantly higher in patients with NF1 (45%) than in controls (10%). Patients also presented more severe perceived disability and hopelessness and more frequent psychiatric disorders than controls. Multivariable logistic regression analysis showed that perceived disability was independently associated with the presence of suicidal ideation in patients with NF1.

CONCLUSIONS

In conclusion, our results showed that suicidal ideation was present in almost half of patients with NF1, suggesting the importance of suicide assessment in these patients.Key pointsPatients with NF1 have an increased suicide ideation when compared to healthy controlsIncreased suicidal ideation correlates with perceived disability, but not with the presence of psychiatric disordersAssessment of suicidal ideation should be performed in patients with NF1.

Several low back pain-related misbeliefs are still around in 2020: A cross-sectional survey in Belgium

BACKGROUND AND PURPOSE

Low back pain (LBP)-related misbeliefs are known to be among risk factors for LBP chronification and for persistence of chronic pain. The main objective of this study was to investigate the current LBP-related beliefs in the general population in Belgium, considering the fact that the last survey in Belgium about the topic was conducted more than 15 years ago.

METHODS

A cross-sectional study design was used. Belgian adults (>17 years old) were recruited in the three regions of the country by means of non-probabilistic recruitment methods. Participants were invited to fill in a battery of questionnaires including demographic questions as well as questions about their LBP history and the LBP Beliefs Questionnaire (LBPBQ).

RESULTS

A total of 3724 individuals participated in the study. The LBPBQ scores indicated several LBP-related misbeliefs. About 15%-25% of participants still think that imaging tests can always identify the cause of pain and that bed rest is the mainstay of therapy. The majority of the participants think that "unnecessary" movements should be avoided when having LBP (58% of the respondents), and that they should "take it easy" until the pain goes away (69%). Most respondents also had maladaptive/wrong expectations, for example, a systematic worsening with time (65%) and a need for surgery in case of disc herniation (54%).

CONCLUSIONS

The present study suggests that in 2020 several LBP-related misbeliefs are still current in Belgium, particularly regarding the vulnerability of the spine. Therefore, further efforts to improve LBP-related beliefs/knowledge in the general population are necessary.

How does Gender Influence Sustainable Return to Work Following Prolonged Work Disability? An Interpretive Description Study

PURPOSE

A sustainable return to work (S-RTW) following prolonged work disability poses different challenges, depending on gender. This article provides a synthesis of gender differences in the issues and factors influencing the S-RTW of workers following such a disability.

METHODS

Using an interpretive description method, an integrative review was conducted of the literature on gender differences in S-RTW issues and factors associated with four major causes of work disability. The initial review concerned the 2000-2016 literature; it was subsequently updated for November 2016-March 2020. To explore and contextualise the results, four focus groups were held with stakeholders representing the workplace, insurance, and healthcare systems and workers. Qualitative thematic analysis was performed.

RESULTS

A total of 47 articles were reviewed, and 35 stakeholders participated in the focus groups. The prevailing traditional gender roles were found to have a major gender-specific influence on the attitudes, behaviours, processes and outcomes associated with S-RTW. These differences related to the (1) cumulative workload, (2) work engagement, and (3) expressed and addressed needs.

CONCLUSIONS

The results highlight the importance of taking into account both professional and personal aspects when integrating gender issues into the assessment of workers' needs and subsequently into interventions.

Pain interference may be an important link between pain severity, impairment, and self-reported disability in participants with wrist/hand pain

STUDY DESIGN

Cross-sectional.

INTRODUCTION

Pain severity, sensory and motor impairment, and psychological (distress and anxiety) and social factors have previously been related to self-reported disability in persons with wrist and hand pain.

PURPOSE OF THE STUDY

The purpose of this study to determine the relative contribution of pain severity, measures of impairment (sensory and motor function), psychosocial factors, and pain interference on self-reported disability experienced by persons with heterogeneous orthopedic injuries and conditions of the wrist and hand.

METHODS

Measures of disability and pain severity as well as measures of sensory (pressure pain thresholds, joint position sense), motor (grip strength, Purdue pegboard), and cognitive performance (Stroop test) and psychosocial variables related to pain and participation (West Haven-Yale Multidimensional Pain Inventory) were administered to 60 participants with wrist and hand pain. Pearson product correlations controlled for age and sex, and multiple linear regression was performed to determine the relationship between measures of impairment, pain severity, psychosocial variables, and pain interference with self-reported disability assessed with the Disability of Arm, Shoulder and Hand (DASH) questionnaire.

RESULTS

The best-fitting regression model with DASH scores entered as the dependent variable (F_4,50 = 28.8, P < .01) included MPI Pain Interference (β = -0.54), Life Control (β = -0.16), Purdue pegboard scores (β = -0.32), and Stroop test times (β = 0.21). Pain Interference had the strongest correlation with self-reported disability (adjusted R² = 0.67, P < .01).

CONCLUSION

Pain interference appears to be an important factor explaining the link between impairment, pain severity, and self-reported disability. Addressing pain interference may be important to improve outcomes in this population.

Psychological Factors Associated with Functional Disability in Patients with Hip and Knee Osteoarthritis

Several studies have shown an association between psychosocial variables and functional capacity in chronic pain processes such as osteoarthritis. The aim of this study was to test a structural equations model that shows the predictive weight of certain variables such as catastrophizing, self-efficacy and kinesiophobia on functional pain and WOMAC subscales scores of pain and physical function of older patients diagnosed with hip and knee osteoarthritis. We also assessed the specific weight of age in terms of the factors. The study was conducted on a sample of 170 patients (142 women and 28 men mean age, 74.44 years range, 50-96 years). The main variables evaluated were WOMAC subscales scores of pain and physical function, self-efficacy, catastrophizing and kinesiophobia. To assess these variables, we used the Spanish validated version of the Western Ontario and McMaster Universities questionnaire, the Chronic Pain Self-Efficacy Scale, the Pain Catastrophizing Scale and the Tampa Scale for Kinesiophobia, respectively. We tested a structural equations model (IBM SPSS Amos version 22). The results showed the predominant predictive weight (both direct and indirect) of catastrophizing while simultaneously ruling out the relevance of age as a predictor of WOMAC subscales scores of pain and physical function. This study provides data of interest on the explanatory mechanisms that underlie the direct and inverse relationships between the studied psychological variables.

Unintended consequences: quantifying the benefits, iatrogenic harms and downstream cascade costs of musculoskeletal MRI in UK primary care

OBJECTIVES

The largest proportion of general practitioner (GP) magnetic resonance imaging (MRI) is musculoskeletal (MSK), with consistent annual growth. With limited supporting evidence and potential harms from early imaging overuse, we evaluated practice to improve pathways and patient safety.

METHODS

Cohort evaluation of routinely collected diagnostic and general practice data across a UK metropolitan primary care population. We reviewed patient characteristics, results and healthcare utilisation.

RESULTS

Of 306 MSK-MRIs requested by 107 clinicians across 29 practices, only 4.9% (95% CI ±2.4%) appeared clearly indicated and only 16.0% (95% CI ±4.1%) received appropriate prior therapy. 37.0% (95% CI ±5.5%) documented patient imaging request. Most had chronic symptoms and half had psychosocial flags. Mental health was addressed in only 11.8% (95% CI ±6.3%) of chronic sufferers with psychiatric illness, suggesting a solely pathoanatomical approach to MSK care. Only 7.8% (95% CI ±3.0%) of all patients were appropriately managed without additional referral. 1.3% (95% CI ±1.3%) of scans revealed diagnoses leading to change in treatment (therapeutic yield). Most imaged patients received pathoanatomical explanations to their symptoms, often based on expected age or activity-related changes. Only 16.7% (95% CI ±4.2%) of results appeared correctly interpreted by GPs, with spurious overperception of surgical targets in 65.4% (95% CI ±5.3%) who suffered 'low-value' (ineffective, harmful or wasteful) post-MRI referral cascades due to misdiagnosis and overdiagnosis. Typically, 20%-30% of GP specialist referrals convert to a procedure, whereas MRI-triggered referrals showed near-zero conversion rate. Imaged patients experienced considerable delay to appropriate care. Cascade costs exceeded direct-MRI costs and GP-MSK-MRI potentially more than doubles expenditure compared with physiotherapist-led assessment services, for little-to-no added therapeutic yield, unjustifiable by cost-consequence or cost-utility analysis.

CONCLUSION

Unfettered GP-MSK-MRI use has reached unaccceptable indication creep and disutility. Considerable avoidable harm occurs through ubiquitous misinterpretation and salient low-value referral cascades for two-thirds of imaged patients, for almost no change in treatment. Any marginally earlier procedural intervention for a tiny fraction of patients is eclipsed by negative consequences for the vast majority. Only 1-2 patients need to be scanned for one to suffer mismanagement. Direct-access imaging is neither clinically, nor cost-effective and deimplementation could be considered in this setting. GP-MSK-MRI fuels unnecessary healthcare utilisation, generating nocebic patient beliefs and expectations, whilst appropriate care is delayed and a high burden of psychosocial barriers to recovery appear neglected.

Psychometric examination of short forms from the University of Washington pain-related self-efficacy and concerns about pain item banks in patients with low back pain

PURPOSE

This study examined the psychometric properties of custom short forms assessing pain-related self-efficacy and catastrophizing, which are important psychosocial constructs for individuals with pain conditions. Short forms were derived from the University of Washington concerns about pain (UWCAP) and pain-related self-efficacy (UWPRSE) item banks.

METHODS

Participants with low back pain (LBP) in a clinical trial (n = 241) examining nonpharmacologic treatments completed the 8-item UWCAP and 9-item UWPRSE and a numeric pain intensity rating, Oswestry Disability and Fear-Avoidance Beliefs questionnaires at baseline, 1-, 4- and 12-weeks after enrollment. Cronbach's alpha and intraclass correlation coefficients estimated internal consistency and test-retest reliability, respectively. Floor and ceiling effects for the UWCAP and UWPRSE were examined. Concurrent validity was evaluated with univariate correlation coefficients and predictive validity with multivariate regression models. Participants were divided into categories of treatment responsiveness based on a single-item global rating measure, and UWPRSE and UWCAP change scores and standardized effect sizes were calculated in each category.

RESULTS

Both short forms had good internal consistency (α = 0.89-0.90) and test-retest reliability (ICC = 0.77-0.85), without substantial floor or ceiling effects. As expected, the UWCAP was positively correlated, and UWPRSE negatively correlated, with concurrent measures of pain intensity, disability and fear-avoidance beliefs. The UWCAP added to the prediction model for 4-week disability outcomes (β = 0.25, p = 0.008). Responsiveness was supported by the mean change scores and effect sizes across treatment response categories.

CONCLUSION

The UWCAP and UWPRSE short forms demonstrated acceptable psychometric properties, supporting future research on the role of these constructs in the management of persons with LBP.

Scale Shortening and Decrease in Measurement Precision: Analysis of the Pain Self-Efficacy Questionnaire and Its Short Forms in an Italian-Speaking Population With Neck Pain Disorders

OBJECTIVE

Short (2- and 4-item) forms of the Pain Self-Efficacy Questionnaire (PSEQ) have been proposed, but their measurement precision at the individual level is unclear.The purpose of this study was to analyze the Rasch psychometric characteristics of PSEQ and its 3 short forms (one 4-item and two 2-item versions) in an Italian-speaking population with neck pain (NP) disorders and compare their measurement precision at the individual level through calculation of the test information function (TIF).

METHODS

Secondary analysis of data from a prospective single-group observational study was conducted. In 161 consecutive participants (mean age = 45 years [SD = 14]; 104 women) with NP disorders, a Rasch analysis was performed on each version of the PSEQ (full scale plus 3 short forms), and the TIF was calculated to examine the degree of measurement precision in estimating person ability over the whole measured construct (pain self-efficacy).

RESULTS

In all versions of the PSEQ, the rating scale fulfilled the category functioning criteria, and all items showed an adequate fit to the Rasch model. The TIF showed a bell-shaped distribution of information, with an acceptable measurement precision (standard error <0.5) for persons with a wide range of ability; conversely, measurement precision was unacceptably low in each short form (particularly the two 2-item versions).

CONCLUSIONS

The results confirm and expand reports on the sound psychometric characteristics of PSEQ, showing for the first time, to our knowledge, its conditional precision in estimating pain self-efficacy measures in Italian individuals with NP disorders. The study cautions against use of the 3 PSEQ short forms for individual-level clinical decision-making.

IMPACT

Short scales are popular in rehabilitation settings largely because they can save assessment time and related costs. The psychometric characteristics of the 10-item PSEQ were confirmed and deepened, including its precision in estimating individual pain self-efficacy at different levels of this latent variable. On the other hand, low measurement precision of the 3 PSEQ short forms cautions against their use for individual judgments.

Attitudes Toward Aging Among Patients With Upper Extremity Illness

Background: An adaptive attitude toward aging might limit symptom intensity and magnitude of limitations. This study sought factors associated with attitudes toward aging (measured with the Brief Aging Perceptions Questionnaire [B-APQ]) and studied the relationship of having an age-related disease to magnitude of limitations, pain intensity, patient satisfaction, and patient comfort with completing a questionnaire about attitudes toward aging. We also looked for a subset of questions from B-APQ that maintained the construct validity and internal consistency of B-APQ, without unacceptable flooring or ceiling effects. Methods: A total of 161 upper extremity patients completed the following questionnaires: B-APQ, Patient Health Questionnaire-Short Form, Pain Self-efficacy-Short Form, Pain Catastrophizing Scale-Short Form, Patient-Reported Outcomes Measurement Information System Physical Function-Upper Extremity, pain intensity, satisfaction with the surgeon, and comfort with completing the B-APQ. We created multivariable linear regression models to test for associations. Results: Factors independently associated with less positive perceptions about aging included white race, retired work status, having nonspecific comorbidities, and more catastrophic thinking. Variation in the magnitude of limitations and pain intensity was accounted for by effectiveness of coping strategies rather than attitudes toward aging in particular. A 4-question version of the B-APQ has acceptable performance. Conclusion: Adaptive attitudes toward aging are associated with psychological and social determinants of health. We present a 4-item short form of B-APQ that could be used as a brief measure to assess attitudes toward aging. Interventions to improve adaptiveness to nociception (eg, cognitive behavioral therapy to limit catastrophic thinking) might help with adaptation to age-related changes.

A Novel Biopsychosocial Approach to Neck Pain in Military Helicopter Aircrew

INTRODUCTION: Flight-related neck pain (FRNP) is a frequently reported musculoskeletal complaint among military helicopter aircrew. However, despite its prevalence and suspected causes, little is known of the underpinning pain mechanisms or the impact of neck pain on aircrews in-flight task performance. The biopsychosocial (BPS) approach to health, combined with the contemporary conceptualization of musculoskeletal pain, in which injury and pain are not necessarily synonymous, provides a relatively new holistic framework within which to consider the problem of FRNP in military helicopter aircrew. Combining these concepts, a new conceptual model is proposed to illustrate how biopsychosocial factors may influence pain perception, potentially affecting aircrews capacity to process information and, therefore, threatening in-flight task performance. Recommendations are made for considering the underlying pain mechanisms of FRNP to aid prognoses and guide the development of holistic evidence-based countermeasures for FRNP in military helicopter aircrew. Development of instruments able to measure psychosocial factors, such as self-efficacy and functional ability, validated in the military helicopter aircrew population, would assist this task.Vail RE, Harridge SDR, Hodkinson PD, Green NDC, Pavlou M.

Passive Trunk Exoskeleton Acceptability and Effects on Self-efficacy in Employees with Low-Back Pain: A Mixed Method Approach

Purpose Determinants of successfully introducing passive exoskeletons in the working environment to decrease mechanical loading on the back, are acceptability of the device to management and employees, including self-efficacy of employees when using the device. Therefore, the aim of this study was to assess self-efficacy of employees with low-back pain when using an exoskeleton and the acceptability of such a device to these employees and their managers. Methods We used a mixed method approach. We quantitatively assessed the change in self-efficacy of 17 employees with low-back pain when performing daily activity tasks with the exoskeleton, using the modified spinal function sort (M-SFS). Qualitatively, we conducted a focus group with employees and a double interview with two managers to add more insight and understandings into changes in self-efficacy and to discuss challenges of implementing an exoskeleton in the working environment. Results Self-efficacy significantly increased by 7% when using the exoskeleton. Employees acknowledged the flexibility of the exoskeleton being advantageous to current static external lifting devices, which confirmed the increase of self-efficacy in both static and dynamic tasks. Individual data showed that the increase in self-efficacy was largest for participants, being greatly restricted by their low-back pain. In the focus group, employees confirmed that they are mostly open to wearing the exoskeleton if they suffer from low-back pain. Conclusion If potential challenges, e.g. visibility and potential refusal of wearing an exoskeleton are considered in the implementation strategy, acceptability of and self-efficacy in using the passive trunk exoskeleton would be further improved, potentially contributing to reduced risk of low-back pain.

Patient education materials for non-specific low back pain and sciatica: a protocol for a systematic review and meta-analysis

INTRODUCTION

Low back pain accounts for more disability than any other musculoskeletal condition and is associated with severe economic burden. Patients commonly present with negative beliefs about low back pain and this can have detrimental effects on their health outcomes. Providing evidence-based, patient-centred education that meets patient needs could help address these negative beliefs and alleviate the substantial low back pain burden. The primary aim of this review is to investigate the effectiveness of patient education materials on immediate process, clinical and health system outcomes.

METHODS AND ANALYSIS

The search strategy was developed in collaboration with a librarian and systematic searches will be performed in MEDLINE, EMBASE, CINAHL, PsycINFO and SPORTDiscus. We will also search trial registries and grey literature through the OpenGrey database. Study selection will include a title and abstract scan and full-text review by two authors. Only randomised controlled trials will be included in this review. Trials must include patients with low back pain or sciatica and investigate educational interventions with at least one of the following contrasts: (1) education alone versus no intervention; (2) education alone versus another intervention; (3) education in addition to another intervention versus the same intervention with no education. Data extraction, risk of bias and grading of the quality of evidence will be performed independently by two reviewers. Risk of bias will be assessed using the PEDro scale, and the quality of evidence will be assessed with the Grades of Recommendation, Assessment, Development and Evaluation approach. A random-effects model will be used for each contrast, and results will be pooled if the participants, interventions, and outcomes are homogeneous. If heterogeneity is high (I2 >75%), we will evaluate the magnitude and direction of the differences in effect sizes across studies to determine if it remains reasonable to pool the results. Analyses of acute and subacute low back pain (less than 12 weeks duration) will be performed separately from chronic low back pain (12 weeks or greater duration). Likewise, analyses of short-term (less than 6 months) and long-term (6 months or greater) follow-up will be performed separately. Subgroup analyses will be performed on non-specific low back pain, sciatica and mixed populations.

ETHICS AND DISSEMINATION

Ethical approval is not required for this review. This study, along with its results, will be published in a peer-reviewed journal.

An evidence-based structured one-year programme to sustain physical activity in patients with heart failure in primary care: A non-randomized longitudinal feasibility study

Aim

The primary objective of this non-randomized feasibility study was to test a 1-year model programme for sustaining/increasing patients' motivation to perform daily physical activity.

Design

Non-randomized longitudinal feasibility study with a one-group repeated measures design.

Methods

The study took place at a primary care centre in mid-Sweden in 2017-2018. The model programme included individual and group-based support, individualized physical activity prescriptions, a wrist-worn activity tracker and an activity diary. The main outcomes were the participants' perceptions of programme feasibility and scores on the Exercise Self-Efficacy Scale.

Results

Seven patients were recruited. Six patients completed the programme that was perceived to imply learning, motivation and support. Compared with baseline, the median score of the Exercise Self-Efficacy Scale improved 3 months after participants completed the programme.

Kinesiophobia contributes to pain-related disability in breast cancer survivors: a cross-sectional study

PURPOSE

Pain is one of the most prevalent problems reported by breast cancer survivors. As this long-lasting complication can result in disabilities on all different domains of functioning, we aimed to clarify the contribution of different factors (pain-related factors, psychosocial factors, and fatigue) to pain-related disability in female breast cancer survivors.

METHODS

Seventy women who had completed their primary breast cancer treatment were included in this cross-sectional study. The following outcome measures were evaluated as independent variables for their contribution to pain-related disability (measured by the Pain Disability Index, with a maximum score of 70): pain intensity, self-reported symptoms of central sensitization, fatigue, illness beliefs, pain catastrophizing, and kinesiophobia. At first, bi- and multivariable regression methods were conducted. Secondly, a stepwise regression analysis was performed to determine the explained variance of the PDI.

RESULTS

Mean score on the PDI was 16 at 4.5 years post-surgery. Multivariable regression analysis revealed higher levels of kinesiophobia as the main contributor to pain-related disability. Ultimately, stepwise regression showed that up to 40% of variance in pain-related disability could be explained by kinesiophobia, negative perceptions related to illness consequences, and pain catastrophizing.

CONCLUSION

This study shows that breast cancer survivors portray moderate self-reported pain-related disability. Kinesiophobia emerged as the main contributor to pain-related disability at this time point, which could shine a light on the improvement of treatment modalities for pain management in this population.

Development, preliminary validation and reliability testing of SEDA - Self-Efficacy in Daily Activities for children with pain

BACKGROUND

Self-efficacy can affect a child's ability to perform important activities, infuse him/her with a sense of control and is likely an integral target for successful treatment in pediatric pain rehabilitation. Modern physical therapy treatment includes behavioral aspects and valid measures of self-efficacy are important for both research and clinical practice. In this study, the aim was to develop and perform preliminary testing of a self-efficacy scale for children and adolescents with pain.

METHODS

Children and adolescents participated, along with researchers and healthcare staff, in developing the Self-Efficacy in Daily Activities (SEDA) measure. A total of 109 children and adolescents seeking physical therapy treatment for pain lasting longer than 3 months responded to the SEDA. Pain and pain-related disability were assessed using the Functional Disability Inventory (FDI). Exploratory analyzes for testing validity and reliability - principal component analyses (PCA), intraclass correlation coefficients (ICCs) and bivariate correlations - were performed.

RESULTS

The PCA revealed a 16-item SEDA and a three-component scale. The components represented self-efficacy for physical activities, self-efficacy for personal care and self-efficacy for daily exertion. Validity correlation analyses showed moderate association between SEDA and FDI, -0.72 (p < .01), and low correlation with pain intensity, -0.29 (p = .03).

CONCLUSIONS

The 16-item SEDA has satisfactory psychometric properties in children moderately affected by long-term pain. Further validation of the SEDA in other populations and confirmatory analyses are warranted.

Behavioural activation and inhibition systems in relation to pain intensity and duration in a sample of people experiencing chronic musculoskeletal pain

BACKGROUND

There is potential clinical utility in tailoring patients' pain management based on behavioural tendencies. Previous work demonstrates a link between behavioural approach/inhibition and pain experience.

OBJECTIVES

To investigate the relationship of pain intensity and duration with behavioural activation and inhibition tendencies and fear-avoidance beliefs, kinesiophobia, and disability, in a sample group (n = 709) reporting chronic musculoskeletal pain.

METHODS

Regression analyses assessed the predictive value of these variables on pain intensity and on pain duration. Differences in behavioural tendencies between groups reporting high and low pain intensities were examined.

RESULTS

Neither pain intensity nor pain duration were correlated with behavioural activation (BAS) and inhibition (BIS). Both pain intensity and duration were correlated with fear-avoidance beliefs (intensity p < .001, duration p = .005), kinesiophobia (intensity and duration both p < .001, and disability (intensity and duration both p < .001). There were significant positive relationships between pain intensity and fear-avoidance beliefs (p < .001), kinesiophobia (p = .021), and disability (p < .001), as well as positive relationships between pain duration and fear-avoidance (p = .543), kinesiophobia (p = .084) and disability (p = .002). Fear-avoidance beliefs, kinesiophobia and disability accounted for 31% of the variance in pain intensity.

CONCLUSIONS

Neither BIS nor BAS significantly related to, or predicted pain intensity or duration. No differences in activation and inhibition tendencies were evident between high and low pain intensity groups. This study provides further support for the inter-relationships between fear-avoidance beliefs, kinesiophobia, disability and pain duration and intensity. No explicit support for behavioural links to pain were shown, however, this may be due to the measurement instrument rather than an invalid theory.

The Opioid-Tolerant Patient: Opioid Optimization

Chronic opioid use and abuse continue to plague our country despite efforts to curtail their use. Patients on chronic opioids (opioids tolerant) who undergo total joint arthroplasty have been clearly shown to have higher rates of complications, infection, and early revision compared to the opioid-naïve patients. The ability to successfully wean patients off of narcotics before surgery remains challenging and fragmented at best. The utilization of a multidisciplinary team that assists with not only preoperative opioids reduction but also postoperative opioids management is critical to the successful management of these patients. This symposium focuses on the opioid-tolerant patients and a comprehensive approach to opioids optimization.

Effects on obstructive sleep apnea severity following a tailored behavioral sleep medicine intervention aimed at increased physical activity and sound eating: an 18-month follow-up of a randomized controlled trial

STUDY OBJECTIVES

Positive effects have been reported following a behavioral sleep medicine (BSM) intervention targeting physical activity and eating behavior in addition to continuous positive airway pressure (CPAP) treatment in patients with obstructive sleep apnea (OSA). Long-term follow-up remains to be explored. The aim was to examine the long-term effects of a tailored BSM intervention addressing physical activity and eating behavior in addition to CPAP treatment in patients with moderate to severe OSA combined with overweight and physical inactivity. Further, the aim was to identify variables at baseline, associated with treatment success regarding OSA severity.

METHODS

Sixty participants (body mass index: 34.5 ± 5.0 kg/m²; apnea-hypopnea index [AHI]: 43.7 ± 21.2 events/h) completed the randomized controlled trial with a follow-up at 18 months. The participants were randomized to either a control group treated with CPAP or an experimental group treated with CPAP and a BSM intervention targeting physical activity and eating behavior changes. OSA was categorized as mild (AHI: 5 to <14.9 events/h), moderate (AHI: 15 to <29.9 events/h), or severe (AHI ≥30 events/h).

RESULTS

Being in the experimental group was associated with a larger improvement (B = -9.353, P = .029) in AHI at the 18-month follow-up compared with being in the control group when adjusting for baseline AHI and body mass index. Improvement in OSA category occurred more frequently in the experimental group participants (n = 11; 36.7%) compared with the control group (n = 2; 6.7%). Deterioration in OSA category was found in 1 (3.3%) participant in the experimental group and 3 (10%) in the control group.

CONCLUSIONS

The importance of a BSM intervention as an adjunct treatment in patients with OSA is emphasized due to its long-term benefits.

Kinesiophobia Levels in Fibromyalgia Syndrome and the Relationship Between Pain, Disease Activity, Depression

Objectives

This study aims to compare kinesiophobia levels between patients with fibromyalgia syndrome (FMS) and healthy volunteers and to investigate the factors associated with kinesiophobia in FMS.

Patients and methods

This case-control study included 88 female patients with FMS (mean age 41.61 years; range 21 to 61 years) and 67 female healthy volunteers (mean age 41.34 years; range 19 to 59 years). The participants' age, body mass index (BMI), and educational status were recorded. Patients were evaluated using a visual analog scale for pain, the Fibromyalgia Impact Questionnaire (FIQ) for disease activity, the Hamilton Depression Scale (HAM-D) for depression level, and the Tampa Scale for Kinesiophobia (TSK) for kinesiophobia. Additionally, the patients' serum 25-hydroxyvitamin D levels were measured.

Results

No significant differences were found between the patient and control groups in terms of age, BMI, and educational status (p>0.05). The mean TSK scores were 42.0±7.6 in the patient group and 37.2±8.8 in the control group. TSK score was significantly higher in the patient group (p<0.001). BMI levels, FIQ scores, and vitamin D concentrations were significantly associated with TSK scores according to the linear regression analysis (p<0.05). However, age, symptom duration, and HAM-D scores were not found to be associated with TSK scores (p>0.05).

Conclusion

Kinesiophobia scores were significantly higher in patients with FMS. Physicians should focus on kinesiophobia when evaluating patients with FMS and inform patients about the importance and treatment strategies of kinesiophobia.

Biased Partner Perceptions of Women's Pain Self-Efficacy in Postpartum Pain During Intercourse: A Dyadic Longitudinal Examination

Postpartum pain during intercourse is a prevalent and distressing problem that has substantial consequences for affected couples. Partner perceptions-such as how partners perceive women's pain self-efficacy-contribute to an individual's pain experience. This study examined whether partners under- or over-estimate women's intercourse pain self-efficacy at 3-months postpartum and the implications of this bias for women's pain and couples' sexual functioning at 3- and 6-months postpartum. Women who reported pain during intercourse and their partners (N = 89 couples) completed online measures assessing pain self-efficacy (own or partner perceptions), pain intensity, and sexual functioning at 3- and 6-months postpartum. Analyses were based on the Truth and Bias Model of Judgement and Response Surface Analysis. Partners were accurate in their estimates of women's pain self-efficacy (ie, their estimates were positively correlated with women's), but they also underestimated it by perceiving women to be less efficacious than women themselves reported. When couples showed greater agreement for lower levels of pain self-efficacy at 3 months, women reported greater pain intensity and both partners reported poorer sexual functioning at 3- and 6-months postpartum. Findings may inform interventions that promote pain self-efficacy to improve partner support and couples' sexual functioning. PERSPECTIVE: When women report-and their partners perceive-low levels of women's self-efficacy for managing painful intercourse, women report greater postpartum pain during intercourse and couples indicate poorer sexual functioning. These findings suggest that interventions aimed at promoting couples' agreement at high pain self-efficacy may improve their adjustment to postpartum pain.

Grit in Community-Dwelling Older Adults with Low Back Pain Is Related to Self-Physical Training Habits

INTRODUCTION

Self-management is an effective way to manage chronic low back pain (LBP) and is frequently recommended. However, the psychological aspects, including grit (ie, perseverance and passion for long-term goals), of the habit of self-management remain unclear.

OBJECTIVE

To investigate the relationship between grit and the self-directed exercise.

DESIGN

Cross-sectional observational study.

SETTING

Community-dwelling older adults.

PARTICIPANTS

Fifty-nine older adults with LBP (30 men, 29 women; mean age 72 ± 5 years, range 65-82 years).

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

Primary outcome measures included grit scores on the Short Grit Scale and the number of months performing self-directed exercise. Correlation and multiple regression analyses were performed to determine the relationship between participants' grit and duration of self-directed exercise.

RESULTS

A significant positive correlation between grit and the duration of self-directed exercise habits was observed (r = 0.49, P < .001). Furthermore, in multiple regression analysis, grit was a significant factor of the duration of self-directed exercise.

CONCLUSION

Low grit was associated with reduced self-directed exercise in individuals with LBP self-directed exercise.

Does the awareness of having a lumbar spondylolisthesis influence self-efficacy and kinesiophobia? A retrospective analysis

BACKGROUND

High pain self-efficacy and low kinesiophobia seem related to a better prognosis in patients complaining of low back pain (LBP). The literature stresses the potential negative effects of anatomical defect diagnosis (e.g. lumbar spondylolisthesis) on the psychological profile. The aim of this study is to investigate the relationships between awareness of having a spondylolisthesis, pain self-efficacy and kinesiophobia.

METHODS

A secondary retrospective analysis was done. Ninety-eight subjects with subacute and chronic LBP were included: 49 subjects with diagnosed symptomatic lumbar spondylolisthesis and 49 subjects with diagnosed non-specific LBP. The pain self-efficacy measured with the Pain Self-Efficacy Questionnaire and the fear of movement measured with the Tampa Scale of Kinesiophobia were considered variables to investigate, whereas diagnosis and demographic/clinical variables were considered predictors or potential confounders.

RESULTS

By comparing the two groups, the awareness of having a spondylolisthesis did not significantly influence neither pain self-efficacy (p = 0.82), nor kinesiophobia (p = 0.75). Higher perceived pain reduces pain self-efficacy and increases kinesiophobia in both groups (p = 0.002 and p = 0,031 respectively).

CONCLUSIONS

It seems that the awareness of an anatomical defect as spondylolisthesis does not significantly affect the beliefs of carry out activities and movements despite the pain. Other studies with wider samples are required, to confirm these preliminary results.

Is there a relationship between self-efficacy, disability, pain and sociodemographic characteristics in chronic low back pain? A multicenter retrospective analysis

Background

Pain-related self-efficacy is defined as the beliefs held by people with chronic pain that certain activities can be carried out despite the pain. Poor self-efficacy is an obstacle to the recovery and predicts long-term disability. The aims of this study are to investigate the prevalence of poor pain self-efficacy in Italian subjects with chronic low back pain (LBP), and to inquire the relationships between self-efficacy, disability, pain, and main demographic and clinical characteristics.

Methods

A secondary multicenter retrospective analysis was done on 310 outpatients with chronic non-specific LBP. The pain self-efficacy measured with the Pain Self-Efficacy Questionnaire (PSEQ), the disability measured with the Roland & Morris Disability Questionnaire, and the pain intensity measured with the Numerical Rating Scale were considered variables to investigate, whereas demographic and clinical variables were considered predictors or potential confounders. A 40/60 PSEQ score was adopted as cut-off to distinguish between good and poor self-efficacy.

Results

199 subjects (64.2% of the sample) showed poor self-efficacy. The odds of having poor self-efficacy appeared significantly related to female gender (OR = 1.80, 95%CI [1.12;2.90]; p = 0.015) and drugs use (OR = 1.68, 95%CI [1.06;2.70]; p = 0.029). Significant relationships also emerged between disability and higher age (β = 0.07, 95%CI [0.01; 0.12]; p = 0.02), being female (β = 1.80, 95%CI [0.32;3.29]; p = 0.018), low educational level (β = − 1.68, 95%CI [− 2.59;-3.29]; p < 0.001), higher height (β = − 0.08, 95%CI [− 0.158;-0.002]; p = 0.045), pain duration [mos] (β = 0.01, 95%CI [0.001;0.021]; p = 0.041), and drugs use (β = 2.86, 95%CI [1.44;4.27]; p < 0.001). The amount of pain appeared significantly related to educational level (β = − 0.47, 95%CI [− 0.76;-0.182]; p < 0.001), smoking (β = 0.56, 95%CI [0.09; 1.03]; p = 0.021), height (β = − 0.03, 95%CI [− 0.05; − 0.002]; p = 0.036), and drugs use (β = 0.81, 95%CI [0.399;1.22]; p < 0.001). No significant correlation appeared among weight, body mass index, and referred pain neither in relation to self-efficacy, nor in relation to pain/disability.

Conclusions

The majority of our sample, composed of Italian people complained of chronic LBP, shows poor self-efficacy. Female gender and drugs use are significantly related to poor self-efficacy, low educational level negatively influences the amount of perceived pain and disability, and older age and smoking are related to disability and pain intensity, respectively. The knowledge of these sociodemographic and clinical characteristics potentially influencing chronic LBP may be useful to address more efforts towards the most negatively impacted subjects, among the entire population complained of chronic LBP.
