Physiotherapists' experiences of implementation of the BetterBack model of care for low back pain in primary care - a focus group interview study

INTRODUCTION

The BetterBack model of care (MoC), a best practice physiotherapy MoC for low back pain (LBP), was implemented in Swedish primary care to improve management of patients with LBP and provide patients with support tools to better self-manage episodes of LBP.

PURPOSE

The objective was to describe how physiotherapists in primary care experienced the implementation of the BetterBack MoC for LBP.

METHODS

Focus group interviews were conducted with physiotherapists in 2018-2019, 14-18 months after the introduction of the BetterBack MoC. Data were analyzed using qualitative content analysis.

RESULTS

Five focus group interviews with 23 (15 female and 8 male) physiotherapists, age range 24-61 years were analyzed. A supportive organization and adaptation to the local culture, combined with health care professionals' attitudes and collaboration between physiotherapists emerged as important factors for a successful implementation and for long-term sustainability of the MoC. Physiotherapists had differing opinions if the implementation led to change in clinical practice. Improved confidence in how to manage patients with LBP was expressed by physiotherapists.

CONCLUSIONS

Several barriers and facilitators influence the implementation of a best practice physiotherapy MoC for LBP in primary care, which need to be considered in future implementation and sustainability processes.

Acute exercise as active inference in chronic musculoskeletal pain, effects on gait kinematics and muscular activity in patients and healthy participants: a study protocol for a randomised controlled laboratory trial

INTRODUCTION

Chronic musculoskeletal pain is a highly prevalent, complex and distressing condition that may negatively affect all domains of life. In view of an active inference framework, and resting on the concept of allostasis, human movement per se becomes a prerequisite for health and well-being while chronic pain becomes a sign of a system unable to attenuate an allostatic load. Previous studies on different subgroups of chronic pain conditions have demonstrated alterations in gait kinematics and muscle activity, indicating shared disturbances in the motor system from long-term allostatic load. We hypothesise that such alterations exist in heterogenous populations with chronic musculoskeletal pain, and that exposure to acute and controlled exercise may attenuate these alterations. Therefore, the main aim of this study is to investigate the acute effects of exercise on gait kinematics and activity of the back and neck muscles during diverse walking conditions in patients with chronic musculoskeletal pain compared with a reference sample consisting of healthy participants.

METHODS AND ANALYSIS

This two-sample two-armed parallel randomised controlled laboratory trial will include 40 participants with chronic musculoskeletal pain (>3 months) and 40 healthy participants. Participants will be randomly allocated to either 30 min of aerobic exercise or rest. Primary outcomes are gait kinematics (walking speed, step frequency, stride length, lumbar rotation, gait stability) and muscular activity (spatial and temporal) of the back and neck during diverse walking conditions. Secondary outcomes are variability of gait kinematics and muscle activity and subjective pain ratings assessed regularly during the trial.

ETHICS AND DISSEMINATION

The study has been approved by the Regional Ethics Review Board in Uppsala, Sweden (#2018/307). Findings will be disseminated via conference presentations, publications in peer-reviewed journals and engagement with patient support groups and clinicians.

Are illness perceptions and patient self-care enablement mediators of treatment effect in best practice physiotherapy low back pain care? Secondary mediation analyses in the BetterBack trial

INTRODUCTION

A best practice physiotherapy model of care (BetterBack MoC) for low back pain (LBP) aimed to improve patients' illness perceptions and self-care enablement, according to the Common-Sense Model of Self-Regulation (CSM).

OBJECTIVE

To confirm if illness perceptions and patient self-care enablement, in line with the CSM, are mediators of treatment effects on disability and pain of the BetterBack MoC for patients with LBP compared to routine primary care. A secondary aim was to explore if illness perceptions and patient self-care enablement are mediators of guideline adherent care.

METHODS

Pre-planned single mediation analyses tested whether hypothesized mediators at 3 months mediated the treatment effect of the MoC (n = 264) compared to routine care (n = 203) on disability and pain at 6 months. Secondary mediation analyses compared guideline adherent care with non-adherent care.

RESULTS

No indirect effects were identified. The BetterBack intervention did not have superior effects over routine care on the hypothesized mediators. Illness perceptions and self-care enablement were significantly associated with disability and pain at 6 months. Secondary analyses showed significant indirect effects of guideline adherent care through tested mediators.

CONCLUSION

Despite no indirect effects, patients' illness perceptions and self-care enablement were associated with disability and back pain intensity outcomes and are potentially relevant treatment targets.

Healthcare Professionals' Perceptions of and Attitudes towards a Standardized Content Description of Interdisciplinary Rehabilitation Programs for Patients with Chronic Pain-A Qualitative Study

Interdisciplinary pain rehabilitation (IPR) is a recommended treatment for people with chronic pain. An inadequate description of the content of IPR programs makes it difficult to draw conclusions regarding their effects. The purpose of this study was to describe the perceptions and attitudes of healthcare professionals toward a content description of IPR programs for patients with chronic pain. Individual interviews with healthcare professionals (n = 11) working in IPR teams in Sweden were conducted between February and May 2019. Analysis of the interviews resulted in a theme: interdisciplinary pain rehabilitation is a complex intervention, with three categories: limitations in the description of IPR programs; lack of knowledge about IPR and chronic pain; and facilitating and hindering factors for using the content description of IPR programs. Conclusion: Healthcare professionals perceived that IPR programs could be described through a general content description. A general content description could enhance the quality of IPR programs through a better understanding of their content and a comparison of different IPR programs. Healthcare professionals also expressed the importance of a content description being a guide rather than a steering document.

Interdisciplinary Multimodal Pain Rehabilitation in Patients with Chronic Musculoskeletal Pain in Primary Care-A Cohort Study from the Swedish Quality Registry for Pain Rehabilitation (SQRP)

Chronic pain is a major public health issue. Mounting evidence suggests that interdisciplinary multimodal pain rehabilitation programs (IMMRPs) performed in specialist pain care are an effective treatment for patients with chronic pain, but the effects of such treatment if performed in primary care settings have been less studied. The aims of this pragmatic study were to (1) describe characteristics of patients participating in IMMRPs in primary care; (2) examine whether IMMRPs in primary care improve pain, disability, quality of life, and sick leave 1-year post discharge in patients with chronic pain; and (3) investigate if outcomes differ between women and men. Data from 744 (645 women and 99 men, age range 18-65 years) patients with non-malignant chronic pain included in the Swedish Quality Registry for Pain Rehabilitation Primary Care were used to describe patient characteristics and changes in health and sick leave. At 1-year follow-up, the patients had improved significantly (p < 0.01) in all health outcome measures and had reduced sick leave except in men, where no significant change was shown in physical activity level. This study indicates that MMRPs in primary care improved pain and physical and emotional health and reduced sick leave, which was maintained at the 1-year follow-up.

Patient Education Improves Pain and Health-Related Quality of Life in Patients with Established Spinal Osteoporosis in Primary Care-A Pilot Study of Short- and Long-Term Effects

Fragility fractures, in particular vertebral fractures, are associated with high morbidity, including chronic pain and reduced health-related quality of life. We aimed to investigate the short- and long-term effects of patient education, including interdisciplinary themes, with or without physical training or mindfulness/medical yoga for patients with established spinal osteoporosis in primary care. Osteoporotic persons aged sixty years or older with one or more vertebral fractures were randomized to theory only, theory and physical exercise, or theory and mindfulness/medical yoga and were scheduled to once a week for ten weeks. Participants were followed up by clinical tests and questionnaires. Twenty-one participants completed the interventions and the one-year follow-up. Adherence to interventions was 90%. Pooled data from all participants showed significant improvements after intervention on pain during the last week and worst pain, and reduced painkiller use (any painkillers at baseline 70% [opioids 25%] vs. post-intervention 52% [opioids 14%]). Significant improvements were seen regarding RAND-36 social function, Qualeffo-41 social function, balance, tandem walking backwards, and theoretical knowledge. These changes were maintained at the 1-year follow-up. Patient group education combined with supervised training seems to have positive effects on pain, and physical function in persons with established spinal osteoporosis. The improved quality of life was maintained at the 1-year follow-up.

Evaluation of the implementation and effectiveness of a multifactorial intervention strategy for safe patient handling and movement in the healthcare sector: a study protocol of a cluster randomised controlled trial

INTRODUCTION

Healthcare workers with physically demanding work tasks, such as patient handling and movement (PHM), are at high risk of musculoskeletal disorders. To facilitate safe PHM and prevent musculoskeletal disorders, a combination of workplace interventions, including risk assessments, is needed. The aim of this study is to implement and evaluate a multifactorial intervention strategy for safe PHM and compare it with a single intervention strategy.

METHODS AND ANALYSIS

This cluster randomised controlled trial will compare a multifactorial intervention strategy with a single intervention strategy for safe PHM in workplaces in the Swedish regional and municipal healthcare systems. At least twelve healthcare units will be recruited. Care units belonging to arm A will receive: (1) guidelines for PHM, (2) training modules, (3) risk assessment with TilThermometer, (4) risk assessment with Downtown Fall Risk Index and (5) work environment mapping. Care units belonging to Arm B will receive interventions (1) and (5). The two strategies will be evaluated with regards to (1) the primary outcome of the applied strategies' intervention effectiveness (safety climate in relation to aspects of PHM) and (2) the primary implementation outcome (acceptability, appropriateness and feasibility). This study will also explore the implementation process and intervention fidelity, examine the influence of contextual factors and investigate participants' experiences of working with strategies for safe PHM. A mix of quantitative and qualitative methods will be used. The data collection is based on questionnaires, interviews and field notes of contextual factors.

ETHICS AND DISSEMINATION

The study is approved by the Swedish national ethical board (Dnr 2021-00578). Study results will be published in peer-reviewed journals, presented at conferences and distributed on social media. A lay summary and dissemination strategy will be codesigned with a reference group and participating healthcare units.

Translation and cross-cultural adaptation of the risk assessment instrument TilThermometer for a Swedish version – patient handling in the healthcare sector

Background

Work-related musculoskeletal disorders are common in the healthcare sector due to exposure of physical demanding work tasks. Risk assessment is necessary to prevent injuries and promote a safety culture. The TilThermometer has proved to be useful in the Netherlands for assessing healthcare workers’ physical exposure to patient handling. The aim of this study was to translate the risk assessment instrument TilThermometer from Dutch to Swedish, perform cross-cultural adaptation, and evaluate its linguistic validity to a Swedish healthcare context.

Methods

Translation and validation process was performed according to following eight steps: 1) Translation (two translators), 2) Synthesis, 3) Back-translation (two back-translators), 4) Synthesis, 5) Linguistic review (one bilingual reviewer), 6) fifteen experts in a panel review according to Delphi-method, 7) Semi-structured interviewing eleven informants, analyzed using qualitative content analysis and step 8) discussion and input from creators of the instrument.

Results

A new Swedish version, the TilThermometer, was provided through the translation process (steps 1–5). The linguistic validity and usefulness were confirmed thru step 6 and 7. Consensus was reached in the expert review after two rounds, comments were analyzed and grouped into five groups. The qualitative content analyses of the interviews emerged in to three categories: 1) “User-friendly and understandable instrument”, 2) “Further development”, and 3) “Important part of the systematic work-environment management”.

Conclusion

In this study, the cross-cultural adaption and translation performed of the Swedish version of TilThermometer assured linguistic validity. This is this first phase before further testing the psychometrics aspects, inter-rater reliability and feasibility of TilThermometer. In the second phase TilThermometer will be implemented and evaluated together with other measures in the Swedish healthcare sector.

Improved adherence to clinical guidelines for low back pain after implementation of the BetterBack model of care: A stepped cluster randomized controlled trial within a hybrid type 2 trial

BACKGROUND

The BetterBack model of care (MoC) for low back pain (LBP) was recently developed in Swedish physiotherapy (PT) primary care.

OBJECTIVE

To evaluate if PTs' adherence to LBP clinical practice guidelines (CPGs) improves after implementation of the BetterBack MoC (intervention).

METHODS

This was a stepped, single-blinded cluster randomized controlled trial. Patients nested in the three clusters were allocated to routine care (n = 222) or intervention (n = 278). The primary outcome was referral to specialist consultation. This was among five best practice recommendations divided into an assessment quality index (no referral to specialist consultation and no medical imaging) and a treatment quality index (use of educational interventions; use of exercise interventions; no use of non-evidence-based physiotherapy). For overall adherence, patients had to be treated with all five recommendations fulfilled. Logistic regression was used for between-group comparisons.

RESULTS

The proportion of patients receiving referral to specialist consultation during the PT treatment period was low in both groups with no between-group differences. However, patients in the intervention group showed significantly higher assessment quality index, treatment quality index and overall adherence compared to routine care. Adherence to the separate recommendations showed improved stratified number of visits, use of exercise was maintained high, patient educational intervention increased and use of non-evidence-based physiotherapy decreased. A reduction of medical imaging during the physiotherapy treatment period was also observed.

CONCLUSIONS

The adoption of CPGs could be substantially improved by introducing a MoC through PT training and supportive materials.

Patients' experiences of the BetterBack model of care for low back pain in primary care - a qualitative interview study

Purpose: The aim of this study was to describe patient experiences of received primary care for low back pain (LBP) according to the BetterBack Model of Care (MoC) with a focus on illness beliefs and self-management enablement.

Methods: Individual interviews were conducted with 15 adults 4–14 months after receiving treatment according to the BetterBack MoC for LBP in primary care in Sweden. Data were analysed using content analysis.

Results: When analysing the data, the following theme emerged; “Participant understanding of their treatment for low back pain and self-management strategies—a matter of support systems”, comprising the following categories: “Knowledge translation”, “Interaction and dialogue”, “The health care professional support” and “Form organization”. Participants experienced that they had better knowledge about their LBP and received tools to better manage their health condition. The participants expressed good communication with the treating physiotherapist and provided suggestions to further improve the treatment of LBP.

Conclusions: Participants experienced that they had gained new knowledge about their health problems and after the treatment they had the tools to handle their back problems. This suggests that the BetterBack MoC may be used as a basis for a support system to provide valuable tools for self-management for patients with low back pain.

The patient enablement instrument for back pain: reliability, content validity, construct validity and responsiveness

Background

Currently, there are no outcome measures assessing the ability of people with non-specific low back pain to self-manage their illness. Inspired by the ‘Patient Enablement Instrument’, we developed the Patient Enablement Instrument for Back Pain (PEI-BP). The aim of this study was to describe the development of the Patient Enablement Instrument for Back Pain (PEI-BP) and investigate content validity, construct validity, internal consistency, test–retest reliability, measurement error, responsiveness and floor and ceiling effects.

Methods

The PEI-BP consists of 6 items that are rated on a 0–10 Numeric Rating Scale. Measurement properties were evaluated using the COSMIN taxonomy and were based on three cohorts from primary care with low back pain: The content validity cohort (N = 14) which participated in semi-structured interviews, the GLA:D® Back cohort (N = 272) and the test–retest cohort (N = 37) which both completed self-reported questionnaires. For construct validity and responsiveness, enablement was compared to disability (Oswestry Disability Index), back pain beliefs (Brief Illness Perception Questionnaire), fear avoidance (Fear-Avoidance Beliefs Questionnaire—physical activity), mental health (SF-36), educational level and number of previous episodes of low back pain.

Results

The PEI-BP was found to have acceptable content validity, construct validity, reliability (internal consistency, test–retest reliability and measurement error) and responsiveness. The Smallest Detectable Change was 10.1 points illustrating that a patient would have to change more than 1/6 of the scale range for it to be a true change. A skewed distribution towards the high scores were found at baseline indicating a potentially problematic ceiling effect in the current population.

Conclusions

The PEI-BP can be considered a valid and reliable tool to measure enablement on people seeking care for non-specific LBP. Further testing of the PEI-BP in populations with more severe LBP is recommended.

Trial registration: Not applicable.

Hemodynamic responses to In-Bed Cycle Exercise in the acute phase after moderate to severe stroke: A randomized controlled trial

Hemodynamic responses to exercise in the acute phase after moderate to severe stroke have remained poorly investigated. The aim of this randomized controlled study, in which 52 (32 women) patients with moderate to severe stroke were randomized to three weeks of 20 minutes in-bed cycle exercise 5 days per week or to usual care, was to explore the systolic blood pressure (SBP) response to exercise and to evaluate the impact of the intervention on the resting and post-test systolic and diastolic blood pressures and heart rate, and on the systolic blood pressure response to exercise. We found that resting SBP decreased from baseline to post-intervention in both the intervention group (147.7 ± 18.1 mmHg to 125.3 ± 17.1 mmHg, P < .001) and in the control group (147.8 ± 23.7 mmHg to 131.4 ± 14.8 mmHg, P < .001) without a significant difference between the groups (interaction P = .308). However, there was a significant difference (interaction P = .010) regarding how Δ SBP (change in SBP from pre-test to post-test) changed from baseline to post-intervention. In the intervention group, Δ SBP increased from -1.0 ± 15.0 mmHg to 8.5 ± 9.4 mmHg, P = .009, whereas in the control group, Δ SBP decreased from 7.1 + 10.9 mmHg to 4.5 + 11.8 mmHg, P = .395. We conclude that patients randomized to in-bed cycle exercise seemed to normalize their blood pressure response to exercise to a larger extent than patients in the control group.

What Mediates Treatment Effects in a Presurgery Physiotherapy Treatment in Surgical Candidates With Degenerative Lumbar Spine Disorders? A Mediation and Conditional Process Analysis of the PREPARE Randomized Controlled Trial

OBJECTIVES

Treatment guidelines recommend targeting both physical and psychological factors in interventions for degenerative lumbar spine disorders. Studying the treatment mechanisms gives information on key factors explaining the outcome improvement that can refine treatments. This study explores treatment mediators in a physiotherapy treatment on disability, pain intensity, and health-related quality of life in surgical candidates with degenerative lumbar spine disorders compared with waiting-list controls. An additional aim was to evaluate patients' expectation as a moderator of treatment outcome.

MATERIALS AND METHODS

Data collected from 197 patients in a single-blinded randomized controlled trial comparing 9 weeks of multifaceted physiotherapy with waiting-list controls were used in this conditional process analysis. Analysis was carried out on group differences for change in Oswestry Disability Index, Pain Visual Analog Scale (VAS) back pain, EuroQol-5D, and EuroQol-VAS. The putative moderation role of expectations and mediation role of change in physical variables and psychosocial variables were tested.

RESULTS

Change in self-efficacy mediated improvement in all outcomes. Improvement in Oswestry Disability Index was also mediated by change in depression; VAS was mediated by change in fear-avoidance beliefs; and EuroQol-VAS was mediated by change in activity level and fear avoidance beliefs. Improvements were moderated by patients' treatment expectations.

DISCUSSION

Self-efficacy, fear-avoidance beliefs, physical activity level, and patients' treatment expectations were found to be important factors explaining treatment effects. Self-efficacy was the consistent mediator for effects of the presurgical physiotherapy on disability, back pain intensity, and health-related quality of life.

A cost-utility analysis of multimodal pain rehabilitation in primary healthcare

OBJECTIVES

Multimodal rehabilitation programs (MMRPs) have been shown to be both cost-effective and an effective method for managing chronic pain in specialist care. However, while the vast majority of patients are treated in primary healthcare, MMRPs are rarely practiced in these settings. Limited time and resources for everyday activities alongside the complexity of chronic pain makes the management of chronic pain challenging in primary healthcare and the focus is on unimodal treatment. In order to increase the use of MMRPs incentives such as cost savings and improved health status in the patient group are needed. The aim of this study was to evaluate the cost-effectiveness of MMRPs for patients with chronic pain in primary healthcare in two Swedish regions. The aim of this study was to evaluate the cost-effectiveness of MMRPs at one-year follow-up in comparison with care as usual for patients with chronic pain in primary healthcare in two Swedish regions.

METHODS

A cost-utility analysis was performed alongside a prospective cohort study comparing the MMRP with the alternative of continuing with care as usual. The health-related quality of life (HRQoL), using EQ5D, and working situation of 234 participants were assessed at baseline and one-year follow-up. The primary outcome was cost per quality-adjusted life year (QALY) gained while the secondary outcome was sickness absence. An extrapolation of costs was performed based on previous long-term studies in order to evaluate the effects of the MMRP over a five-year time period.

RESULTS

The mean (SD) EQ5D index, which measures HRQoL, increased significantly (p<0.001) from 0.34 (0.32) to 0.44 (0.32) at one-year follow-up. Sickness absence decreased by 15%. The cost-utility analysis showed a cost per QALY gained of 18 704 € at one-year follow-up.

CONCLUSIONS

The results indicate that the MMRP significantly improves the HRQoL of the participants and is a cost-effective treatment for patients with chronic pain in primary healthcare when a newly suggested cost-effectiveness threshold of 19 734 € is implemented. The extrapolation indicates that considerable cost savings in terms of reduced loss of production and gained QALYs may be generated if the effects of the MMRP are maintained beyond one-year follow-up. The study demonstrates potential benefits of MMRPs in primary healthcare for both the patient with chronic pain and the society as a whole. The cost-effectiveness of MMRPs in primary healthcare has scarcely been studied and further long-term studies are needed in these settings.

Effects of In-Bed Cycle Exercise in Patients With Acute Stroke: A Randomized Controlled Trial

Objective

To investigate the effects of in-bed cycle exercise in addition to usual care in patients with acute stroke, National Institutes of Health Stroke Scale (NIHSS) 7-42, regarding walking ability, functional outcomes, and inpatient care days.

Design

Randomized controlled trial.

Setting

Hospital care.

Participants

Patients (N=56) with stroke NIHSS 7-42 were recruited 24-48 hours after stroke onset from 2 stroke units in Sweden.

Interventions

Both groups received usual care. The intervention group also received 20 minutes bed cycling 5 days per week with a maximum of 15 sessions.

Main Outcome Measures

The primary outcome was median change in walking ability measured with the 6-minute walk test (6MWT). Secondary outcome measures included the median change in modified Rankin Scale (mRS), Barthel Index (BI) for activities of daily living, and inpatient care days. Measurements were performed at baseline, post intervention (3 weeks), and at 3-month follow-up.

Results

There was no significant difference in change of walking ability (6MWT) from baseline to follow-up between the intervention and control groups (median, 105m [interquartile range [IQR, 220m] vs 30m [IQR, 118m], respectively, P=.147, d=0.401). There were no significant differences between groups regarding mRS, BI, or inpatient care days. Patients with less serious stroke (NIHSS 7-12) seemed to benefit from the intervention.

Conclusion

Although this study may have been underpowered, patients with stroke NIHSS 7-42 did not benefit from in-bed cycle exercise in addition to usual care after acute stroke. A larger study is needed to confirm our results.

Patients selected to participate in multimodal pain rehabilitation programmes in primary care-a multivariate cross-sectional study focusing on gender and sick leave

Background and aims A multimodal rehabilitation programme (MMRP) is an evidence-based treatment of chronic pain conditions. The complexity involved in chronic pain needs to be identified and evaluated in order to adapt the rehabilitation to patients' needs. The aim was to investigate the multivariate relationships between self-reported variables in patients with chronic pain before taking part in MMRP in primary care, with a special focus on gender and degree of sick leave. Methods Prior to MMRP, 397 patients (339 women and 58 men) filled in a questionnaire about pain, healthcare aspects, health-related quality of life, anxiety and depression, coping, physical function, and work-related variables e.g. sick leave. Data were analysed by principal component analysis (PCA) and partial least square analysis. Results The PCA identified four components that explained 47% of the variation in the investigated data set. The first component showed the largest variation and was primarily explained by anxiety and depression, quality of life, acceptance (activity engagement), and pain-related disability. Gender differences were only seen in one component with the pain variables having the highest loadings. Degree of sick leave was not well explained by the variables in the questionnaire. Conclusions The questionnaire filled out by the patients prior to participation in MMRP in primary care identified much of the complexity of chronic pain conditions but there is room for improvement, e.g. regarding explanation of work-related factors. In the multivariate analysis, gender did not fall out as an important factor for how most patients answered the questions. Implications There are not many studies that describe patients who undergo MMRP in primary care since previously such patients were treated mostly in specialist care. More knowledge is needed about these patients in order to improve rehabilitation plans and interventions. The results suggest that the questionnaire identifies the complexity among chronic pain patients in primary care. The identified components could improve assessment before MMRP and contribute to better tailored programmes.

Mindfulness and Modified Medical Yoga as Intervention in Older Women with Osteoporotic Vertebral Fracture

Background: People with osteoporotic vertebral compression fractures (VCFs) have decreased health-related quality of life (HRQoL). Yoga and mindfulness are methods that can promote well-being. Objective: The aim of this article was to explore the effect of mindfulness and modified medical yoga on HRQoL, stress, sleep, and pain in people 60 years or older with a diagnosed osteoporotic VCF. Design: The School of Osteoporosis in Linköping (SOL) is a pilot study with randomized groups. Materials and Methods: The SOL-study was scheduled to once a week for 10 weeks. Ten people were randomized to a theory (T) group, and ten people were randomized to a theory and mindfulness/medical yoga (MMY) group. The educational sessions lasted 60 min and were similar for the groups, but they took place at different facilities. An experienced physiotherapist supervised the MMY sessions for 60 min. Sleep quality and present stress experience were measured on a symmetric Likert scale. The numeric rating scale was used for pain, and EQ-5D, RAND-36, and Qualeffo-41 were used for HRQoL. The patient enablement instrument (PEI) was used to reflect how the participants coped with their illness. Results: Eight women in the MMY-group and seven women in the T-group completed the SOL study interventions. The adherence to the intervention program was 89% in the MMY-group and 87% in the T-group. There was no adverse consequence of the MMY training. After the 10-week intervention period, sleep quality (p = 0.018) and present stress (p = 0.043), but not perceived pain were improved in the MMY-group. The social function (SF) domain was improved in the MMY-group that was measured by both RAND-36 (p = 0.028) and Qualeffo-41 (p = 0.012). There was a trend toward a better PEI-score in the MMY-group compared with the T-group postintervention (p = 0.089). Conclusion: This article suggests that mindfulness and modified medical yoga supervised by a skilled physiotherapist may be a feasible way to improve SF, sleep, and stress in older women with osteoporotic VCFs.

Confidence, attitudes, beliefs and determinants of implementation behaviours among physiotherapists towards clinical management of low back pain before and after implementation of the BetterBack model of care

BACKGROUND

Implementing clinical guidelines is challenging. To facilitate uptake, we developed a model of care (BetterBack Model of Care) and an implementation strategy to support management of low back pain in primary care. The aim of this study was to evaluate physiotherapists´ confidence, attitudes and beliefs in managing patients with low back pain before and after a multifaceted implementation of the BetterBack Model of Care. A further aim was to evaluate determinants of implementation behaviours among physiotherapists.

METHODS

This clinical trial was an experimental before and after study within a hybrid type 2 effectiveness-implementation trial. The primary outcome was Practitioner Self-Confidence Scale (PCS), secondary outcomes were the Pain Attitude and Beliefs Scale for Physiotherapists (PABS-PT) and Determinants of Implementation Behaviour Questionnaire (DIBQ). Data was analysed using repeated measures ANOVA and pairwise comparisons.

RESULTS

One hundred sixteen physiotherapists answered a questionnaire before, directly after, as well as 3 and 12 months after implementation of the Model of Care. PCS improved over time with a large effect size post implementation (ηp2 = 0.197, p < 0.001). Changes in PABS-PT were only significant after 12 months with higher biopsychosocial orientation, (ηp2 = 0.071, p < 0.01) and lower biomedical orientation, (ηp2 = 0.136, p < 0.001). Directly after the workshop, after 3 and 12 months, physiotherapists had high ratings on all DIBQ domains, (scores > 50) implying that all were potential facilitators of the implementation. However, after 3 months, all domains had significantly decreased except for organisation, social influence and patient expectation domains. However, after 12 months, organisation and social influence domains had significantly decreased while domains such as knowledge, skills and beliefs about capabilities returned to initial levels.

CONCLUSIONS

Physiotherapists´ confidence and biopsychosocial orientation increased after implementation and may have the potential to improve management of low back pain in primary care. The implementation behaviour showed mostly facilitating patterns but changed over time, pinpointing a need to repeatedly monitor these changes. This can inform the need for changes of implementation efforts in different phases and support sustainability strategies.

Long-term outcomes of multimodal rehabilitation in primary care for patients with chronic pain

OBJECTIVES

To investigate the outcomes 1 year after multimodal rehabilitation programmes in primary care for patients with chronic pain, both as a whole and for men and women separately. A second aim was to identify predictive factors for not being on sickness absence at follow-up after 1 year.

METHODS

A prospective longitudinal cohort study of 234 patients, 34 men and 200 women, age range 18-65 years, who participated in multimodal rehabilitation programmes in primary care in 2 Swedish county councils. Pain, physical and emotional functioning, coping, health-related quality of life, work-related factors, sickness absence (sick leave, sickness compensation/disability pension) were evaluated prior to and 1 year after multimodal rehabilitation programmes.

RESULTS

Patients showed significant improvements at 1-year follow-up for all measures (all p ≤ 0.004) except satisfaction with vocation (p = 0.060). The proportion of patients on sick leave decreased significantly at follow-up (p = 0.027), while there was no significant difference regarding the proportion of patients on sickness compensation/disability pension (p = 0.087). Higher self-rated work ability was associated with not being on sickness absence at 1-year follow-up (odds ratio (OR) 1.19, confidence interval (CI) 1.21-1.06, p = 0.005).

CONCLUSION

This study indicates that multimodal rehabilitation programmes in primary care could be beneficial for patients with chronic pain, since the outcomes at 1-year follow-up for pain, physical and emotional functioning, coping, and health-related quality of life were positive. However, the effect sizes were small and thus further development of multimodal rehabilitation programmes is warranted in order to improve the outcomes.

Group-based music intervention in Parkinson's disease - findings from a mixed-methods study

Objective:

To evaluate a group-based music intervention in patients with Parkinson’s disease.

Design:

Parallel group randomized controlled trial with qualitative triangulation.

Setting:

Neurorehabilitation in primary care.

Subjects:

Forty-six patients with Parkinson’s disease were randomized into intervention group (n = 26), which received training with the music-based intervention, and control group (n = 20) without training.

Interventions:

The intervention was delivered twice weekly for 12 weeks.

Main measures:

Primary outcome was Timed-Up-and-Go subtracting serial 7’s (dual-task ability). Secondary outcomes were cognition, balance, concerns about falling, freezing of gait, and quality of life. All outcomes were evaluated at baseline, post-intervention, and three months post-intervention. Focus groups and individual interviews were conducted with the intervention group and with the delivering physiotherapists.

Results:

No between-group differences were observed for dual-task ability. Between-group differences were observed for Falls Efficacy Scale (mean difference (MD) = 6.5 points; 95% confidence interval (CI) = 3.0 to 10.0, P = 0.001) and for Parkinson Disease Questionnaire-39 items (MD = 8.3; 95% CI = 2.7 to 13.8, P = 0.005) when compared to the control group post-intervention, but these were not maintained at three months post-intervention. Three themes were derived from the interviews: Expectations versus Results, Perspectives on Treatment Contents, and Key Factors for Success.

Conclusion:

Patient-reported outcomes and interviews suggest that the group-based music intervention adds value to mood, alertness, and quality of life in patients with Parkinson’s disease. The study does not support the efficacy in producing immediate or lasting gains in dual-tasking, cognition, balance, or freezing of gait.

Validity, internal consistency and self-rated change of the patient enablement instrument in patients with chronic musculoskeletal pain

OBJECTIVE

Patient enablement reflects patient's understanding of and coping with illness. The aim of this study was to investigate the content validity, construct validity, internal consistency and self-rated change (SRC) of the Patient Enablement Instrument (PEI) in patients with whiplash-associated disorders, cervical radiculopathy and mixed chronic pain treated in different settings.

DESIGN

Psychometric analyses.

PARTICIPANTS

Patients with disabling non-malignant chronic musculoskeletal pain.

METHODS

Participants answered questionnaires on disability (Neck Disability Index (NDI) or Functional Rating Index (FRI)), anxiety/depression (Hospital Anxiety and Depression Scale; HADS) and general health (EuroQol; EQ-5D). Content validity, construct validity (confirmatory factor analysis), internal consistency and cut-off for SRC were investigated for the PEI after treatment. The SRC value was the receiver operating characteristic (ROC) curve optimal cut-off point.

RESULTS

After treatment all items were completed by 516 patients (mean standard deviation (SD) age 45.1 years (SD 10.1), women 75% (n = 385)). The 1-factor PEI model had approximate fit to the data. The internal consistency Cronbach's alpha was between 0.878 and 0.929 for the 3 groups. Correlations between the PEI and the NDI/FRI, HADS and EQ-5D were fair to good. The SRCROC for whiplash-associated disorders, cervical radiculopathy and mixed chronic pain groups was 5, 6 and 4 points in the PEI, respectively.

CONCLUSION

The PEI showed fair content validity, construct validity and internal consistency. However, the scale needs further development to improve measurement of change.

Effects of pre-surgery physiotherapy on walking ability and lower extremity strength in patients with degenerative lumbar spine disorder: Secondary outcomes of the PREPARE randomised controlled trial

BACKGROUND

Degenerative lumbar spine disorders are common among musculoskeletal disorders. When disabling pain and radiculopathy persists after adequate course of rehabilitation and imaging confirms compressive pathology, surgical decompression is indicated. Prehabilitation aiming to augment functional capacity pre-surgery may improve physical function and activity levels pre and post-surgery. This study aims to evaluate the effect and dose-response of pre-surgery physiotherapy on quadriceps femoris strength and walking ability in patients with degenerative lumbar spine disorders compared to waiting-list controls and their association with postoperative physical activity level.

METHOD

In this single blinded, 2-arm randomised controlled trial, 197 patients were consecutively recruited. Inclusion criteria were: MRI confirmed diagnosis and scheduled for surgery due to disc herniation, lumbar spinal stenosis, degenerative disc disease or spondylolisthesis, ages 25-80 years. Patients were randomised to 9 weeks of pre-surgery physiotherapy or to waiting-list. Patient reported physical activity level, walking ability according to Oswestry Disability Index item 4, walking distance according to the SWESPINE national register and physical outcome measures including the timed ten-meter walk test, maximum voluntary isometric quadriceps femoris muscle strength, patient-rated were collected at baseline and follow-up. Parametric or non-parametric within and between group comparisons as well as multivariate regression was performed.

RESULTS

Patients who received pre-surgery physiotherapy significantly improved in all variables from baseline to follow-up (p < 0.001 - p < 0.05) and in comparison to waiting-list controls (p < 0.001 - p < 0.028). Patients adhering to ≥12 treatment sessions significantly improved in all variables (p < 0.001 - p < 0.032) and those receiving 0-11 treatment session in only normal walking speed (p0.035) but there were no significant differences when comparing dosages. Physical outcome measures after pre-surgery physiotherapy together significantly explain 27.5% of the variation in physical activity level 1 year after surgery with pre-surgery physical activity level having a significant multivariate association.

CONCLUSION

Pre-surgery physiotherapy increased walking ability and lower extremity strength in patients with degenerative lumbar spine disorders compared to waiting-list controls. A clear treatment dose-response response relationship was not found. These results implicate that pre-surgery physiotherapy can influence functional capacity before surgical treatment and has moderate associations with maintained postoperative physical activity levels mostly explained by physical activity level pre-surgery.

The importance of emotional distress, cognitive behavioural factors and pain for life impact at baseline and for outcomes after rehabilitation – a SQRP study of more than 20,000 chronic pain patients

Background and aims

Although literature concerning chronic pain patients indicates that cognitive behavioural variables, specifically acceptance and fear of movement/(re)injury, are related to life impact, the relative roles of these factors in relation to pain characteristics (e.g. intensity and spreading) and emotional distress are unclear. Moreover, how these variables affect rehabilitation outcomes in different subgroups is insufficiently understood. This study has two aims: (1) to investigate how pain, cognitive behavioural, and emotional distress variables intercorrelate and whether these variables can regress aspects of life impact and (2) to analyse whether these variables can be used to identify clinically meaningful subgroups at baseline and which subgroups benefit most from multimodal rehabilitation programs (MMRP) immediately after and at 12-month follow-up.

Methods

Pain aspects, background variables, psychological distress, cognitive behavioural variables, and two life impact variables were obtained from the Swedish Quality Registry for Pain Rehabilitation (SQRP) for chronic pain patients. These data were analysed mainly using advanced multivariate methods.

Results

The study includes 22,406 chronic pain patients. Many variables, including acceptance variables, showed important contributions to the variation in clinical presentations and in life impacts. Based on the statistically important variables considering the clinical presentation, three clusters/subgroups of patients were identified at baseline; from the worst clinical situation to the relatively good situation. These clusters showed significant differences in outcomes after participating in MMRP; the subgroup with the worst situation at baseline showed the most significant improvements.

Conclusions

Pain intensity/severity, emotional distress, acceptance, and life impacts were important for the clinical presentation and were used to identify three clusters with marked differences at baseline (i.e. before MMRP). Life impacts showed complex relationships with acceptance, pain intensity/severity, and emotional distress. The most significant improvements after MMRP were seen in the subgroup with the lowest level of functioning before treatment, indicating that patients with complex problems should be offered MMRP.

Implications

This study emphasizes the need to adopt a biopsychosocial perspective when assessing patients with chronic pain. Patients with chronic pain referred to specialist clinics are not homogenous in their clinical presentation. Instead we identified three distinct subgroups of patients. The outcomes of MMRP appears to be related to the clinical presentation. Thus, patients with the most severe clinical presentation show the most prominent improvements. However, even though this group of patients improve they still after MMRP show a complex situation and there is thus a need for optimizing the content of MMRP for these patients. The subgroup of patients with a relatively good situation with respect to pain, psychological distress, coping and life impact only showed minor improvements after MMRP. Hence, there is a need to develop other complex interventions for them.

A Definition of "Flare" in Low Back Pain: A Multiphase Process Involving Perspectives of Individuals With Low Back Pain and Expert Consensus

Low back pain (LBP) varies over time. Consumers, clinicians, and researchers use various terms to describe LBP fluctuations, such as episodes, recurrences and flares. Although "flare" is use commonly, there is no consensus on how it is defined. This study aimed to obtain consensus for a LBP flare definition using a mixed-method approach. Step 1 involved the derivation of a preliminary candidate flare definition based on thematic analysis of views of 130 consumers in consultation with an expert consumer writer. In step 2, a workshop was conducted to incorporate perspectives of 19 LBP experts into the preliminary flare definition, which resulted in 2 alternative LBP flare definitions. Step 3 refined the definition using a 2-round Delphi consensus with 50 experts in musculoskeletal conditions. The definition favored by experts was further tested with 16 individuals with LBP in step 4, using the definition in three scenarios. This multiphase study produced a definition of LBP flare that distinguishes it from other LBP fluctuations, represents consumers' views, involves expert consensus, and is understandable by consumers in clinical and research contexts: "A flare-up is a worsening of your condition that lasts from hours to weeks that is difficult to tolerate and generally impacts your usual activities and/or emotions." Perspective: A multiphase process, incorporating consumers' views and expert consensus, produced a definition of LBP flare that distinguishes it from other LBP fluctuations.

Who benefits from multimodal rehabilitation - an exploration of pain, psychological distress, and life impacts in over 35,000 chronic pain patients identified in the Swedish Quality Registry for Pain Rehabilitation

Background

Chronic pain patients frequently suffer from psychological symptoms. There is no consensus concerning the prevalence of severe anxiety and depressive symptoms and the strength of the associations between pain intensity and psychological distress. Although an important aspect of the clinical picture is understanding how the pain condition impacts life, little is known about the relative importance of pain and psychological symptoms for individual’s life impact. The aims of this study were to identify subgroups of pain patients; to analyze if pain, psychological distress, and life impact variables influence subgrouping; and to investigate how patients in the subgroups benefit from treatments.

Methods

Background variables, pain aspects (intensity/severity and spreading), psychological distress (depressive and anxiety symptoms), and two life impact variables (pain interference and perceived life control) were obtained from the Swedish Quality Registry for Pain Rehabilitation for chronic pain patients and analyzed mainly using advanced multivariate methods.

Results

Based on >35,000 patients, 35%–40% had severe anxiety or depressive symptoms. Severe psychological distress was associated with being born outside Europe (21%–24% vs 6%–8% in the category without psychological distress) and low education level (20.7%–20.8% vs 26%–27% in the category without psychological distress). Dose relationships existed between the two psychological distress variables and pain aspects, but the explained variances were generally low. Pain intensity/severity and the two psychological distress variables were significantly associated (R²=0.40–0.48; P>0.001) with the two life impact variables (pain interference and life control). Two subgroups of patients were identified at baseline (subgroup 1: n=15,901–16,119; subgroup 2: n=20,690–20,981) and the subgroup with the worst situation regarding all variables participated less in an MMRP (51% vs 58%, P<0.001) but showed the largest improvements in outcomes.

Conclusion

The results emphasize the need to assess both pain and psychological distress and not take for granted that pain involves high psychological stress in the individual case. Not all patients benefit from MMRP. A better matching between common clinical pictures and the content of MMRPs may help improve results. We only partly found support for treatment resistance in patients with psychological distress burden.

Elaborating on the assessment of the risk of bias in prognostic studies in pain rehabilitation using QUIPS-aspects of interrater agreement

BACKGROUND

Many studies have been performed to identify important prognostic factors for outcomes after rehabilitation of patients with chronic pain, and there is a need to synthesize them through systematic review. In this process, it is important to assess the study quality and risk of bias. The "Quality In Prognosis Studies" (QUIPS) tool has been developed for this purpose and consists of several prompting items categorized into six domains, and each domain is judged on a three-grade scale (low, moderate or high risk of bias). The aim of the present study was to determine the interrater agreement of the risk of bias assessment in prognostic studies of patients with chronic pain using QUIPS and to elaborate on the use of this instrument.

METHODS

We performed a systematic review and a meta-analysis of prognostic factors for long-term outcomes after multidisciplinary rehabilitation in patients with chronic pain. Two researchers rated the risk of bias in 43 published papers in two rounds (15 and 28 papers, respectively). The interrater agreement and Cohen's quadratic weighted kappa coefficient (κ) and 95% confidence interval (95%CI) were calculated in all domains and separately for the first and second rounds.

RESULTS

The raters agreed in 61% of the domains (157 out of 258), with similar interrater agreement in the first (59%, 53/90) and second rounds (62%, 104/168). The overall weighted kappa coefficient (kappa for all domains and all papers) was weak: κ = 0.475 (95%CI = 0.358-0.601). A "minimal agreement" between the raters was found in the first round, κ = 0.323 (95%CI = 0.129-0.517), but increased to "weak agreement" in the second round, κ = 0.536 (95%CI = 0.390-0.682).

CONCLUSION

Despite a relatively low interrater agreement, QUIPS proved to be a useful tool in assessing the risk of bias when performing a meta-analysis of prognostic studies in pain rehabilitation, since it demands of raters to discuss and investigate important aspects of study quality. Some items were particularly hard to differentiate in-between, and a learning phase was required to increase the interrater agreement. This paper highlights several aspects of the tool that should be kept in mind when rating the risk of bias in prognostic studies, and provides some suggestions on common pitfalls to avoid during this process.

PREPARE: presurgery physiotherapy for patients with degenerative lumbar spine disorder: a randomized controlled trial

BACKGROUND CONTEXT

Surgery because of disc herniation or spinal stenosis results mostly in large improvement in the short-term, but mild to moderate improvements for pain and disability at long-term follow-up. Prehabilitation has been defined as augmenting functional capacity before surgery, which may have beneficial effect on outcome after surgery.

PURPOSE

The aim was to study if presurgery physiotherapy improves function, pain, and health in patients with degenerative lumbar spine disorder scheduled for surgery.

STUDY DESIGN

A single-blinded, two-arm, randomized controlled trial (RCT).

PATIENT SAMPLE

A total of 197 patients were consecutively included at a spine clinic. The inclusion criteria were patients scheduled for surgery because of disc herniation, spinal stenosis, spondylolisthesis, or degenerative disc disease (DDD), 25-80 years of age.

OUTCOME MEASURES

Primary outcome was Oswestry Disability Index (ODI). Secondary outcomes were pain intensity, anxiety, depression, self-efficacy, fear avoidance, physical activity, and treatment effect.

METHODS

Patients were randomized to either presurgery physiotherapy or standardized information, with follow-up after the presurgery intervention as well as 3 and 12 months post surgery. The study was funded by regional research funds for US$77,342. No conflict of interest is declared.

RESULTS

The presurgery physiotherapy group had better ODI, visual analog scale (VAS) back pain, EuroQol-5D (EQ-5D), EQ-VAS, Fear Avoidance Belief Questionnaire-Physical Activity (FABQ-PA), Self-Efficacy Scale (SES), and Hospital Anxiety and Depression Scale (HADS) depression scores and activity level compared with the waiting-list group after the presurgery intervention. The improvements were small, but larger than the study-specific minimal clinical important change (MCIC) in VAS back and leg pain, EQ-5D, and FABQ-PA, and almost in line with MCIC in ODI and Physical Component Summary (PCS) in the physiotherapy group. Post surgery, the only difference between the groups was higher activity level in the physiotherapy group compared with the waiting-list group.

CONCLUSIONS

Presurgery physiotherapy decreases pain, risk of avoidance behavior, and worsening of psychological well-being, and improves quality of life and physical activity levels before surgery compared with waiting-list controls. These results were maintained only for activity levelspost surgery. Still, presurgery selection, content, dosage of exercises, and importance of being active in a presurgery physiotherapy intervention is of interest to study further to improve long-term outcome.

"The acceptance" of living with chronic pain - an ongoing process: A qualitative study of patient experiences of multimodal rehabilitation in primary care

OBJECTIVE

To explore patient experiences of participating in multimodal pain rehabilitation in primary care.

SUBJECTS

Twelve former patients (7 women and 5 men) in multimodal rehabilitation in primary care were interviewed about their experiences of multimodal rehabilitation.

METHODS

The interviews were analysed using qualitative content analysis.

RESULTS

Analysis resulted in 4 categories: (i) from discredited towards obtaining redress; (ii) from uncertainty towards knowledge; (iii) from loneliness towards togetherness; and (iv) "acceptance of pain": an ongoing process. The results show that having obtained redress, to obtain knowledge about chronic pain, and to experience fellowship with others with the same condition were helpful in the acceptance process. However, there were patients who found it difficult to reconcile themselves with a life with chronic pain after multimodal rehabilitation. To find what was "wrong" and to have a medical diagnosis and cure were important.

CONCLUSION

Patients in primary care multimodal rehabilitation experience a complex, ongoing process of accepting chronic pain. Four important categories were described. These findings will help others to understand the experience and perspective of patients with chronic pain who engage in multimodal rehabilitation.

Effectiveness of implementing a best practice primary healthcare model for low back pain (BetterBack) compared with current routine care in the Swedish context: an internal pilot study informed protocol for an effectiveness-implementation hybrid type 2 trial

INTRODUCTION

Low back pain (LBP) is a major health problem commonly requiring healthcare. In Sweden, there is a call from healthcare practitioners (HCPs) for the development, implementation and evaluation of a best practice primary healthcare model for LBP.

AIMS

(1) To improve and understand the mechanisms underlying changes in HCP confidence, attitudes and beliefs for providing best practice coherent primary healthcare for patients with LBP; (2) to improve and understand the mechanisms underlying illness beliefs, self-care enablement, pain, disability and quality of life in patients with LBP; and (3) to evaluate a multifaceted and sustained implementation strategy and the cost-effectiveness of the BetterBack☺ model of care (MOC) for LBP from the perspective of the Swedish primary healthcare context.

METHODS

This study is an effectiveness-implementation hybrid type 2 trial testing the hypothesised superiority of the BetterBack☺ MOC compared with current routine care. The trial involves simultaneous testing of MOC effects at the HCP, patient and implementation process levels. This involves a prospective cohort study investigating implementation at the HCP level and a patient-blinded, pragmatic, cluster, randomised controlled trial with longitudinal follow-up at 3, 6 and 12 months post baseline for effectiveness at the patient level. A parallel process and economic analysis from a healthcare sector perspective will also be performed. Patients will be allocated to routine care (control group) or the BetterBack☺ MOC (intervention group) according to a stepped cluster dogleg structure with two assessments in routine care. Experimental conditions will be compared and causal mediation analysis investigated. Qualitative HCP and patient experiences of the BetterBack☺ MOC will also be investigated.

DISSEMINATION

The findings will be published in peer-reviewed journals and presented at national and international conferences. Further national dissemination and implementation in Sweden and associated national quality register data collection are potential future developments of the project.

Predictors of multidisciplinary rehabilitation outcomes in patients with chronic musculoskeletal pain: protocol for a systematic review and meta-analysis

BACKGROUND

Chronic musculoskeletal pain is a major public health problem. Early prediction for optimal treatment results has received growing attention, but there is presently a lack of evidence regarding what information such proactive management should be based on. This study protocol, therefore, presents our planned systematic review and meta-analysis on important predictive factors for health and work-related outcomes following multidisciplinary rehabilitation (MDR) in patients with chronic musculoskeletal pain.

METHODS

We aim to perform a synthesis of the available evidence together with a meta-analysis of published peer-reviewed original research that includes predictive factors preceding MDR. Included are prospective studies of adults with benign, chronic (> 3 months) musculoskeletal pain diagnoses who have taken part in MDR. In the studies, associations between personal and rehabilitation-based factors and the outcomes of interest are reported. Outcome domains are pain, physical functioning including health-related quality of life, and work ability with follow-ups of 6 months or more. We will use a broad, explorative approach to any presented predictive factors (demographic, symptoms-related, physical, psychosocial, work-related, and MDR-related) and these will be analyzed through (a) narrative synthesis for each outcome domain and (b) if sufficient studies are available, a quantitative synthesis in which variance-weighted pooled proportions will be computed using a random effects model for each outcome domain. The strength of the evidence will be evaluated using the Grading of Recommendations, Assessment, Development and Evaluation.

DISCUSSION

The strength of this systematic review is that it aims for a meta-analysis of prospective cohort or randomized controlled studies by performing an extensive search of multiple databases, using an explorative study approach to predictive factors, rather than building on single predictor impact on the outcome or on predefined hypotheses. In this way, an overview of factors central to MDR outcome can be made and will help strengthen the evidence base and inform a wide readership including health care practitioners and policymakers.

Altered somatosensory profile according to quantitative sensory testing in patients with degenerative lumbar spine disorders scheduled for surgery

Background

Somatosensory profiling in affected and non-affected body regions can strengthen our insight regarding the underlying pain mechanisms, which can be valuable in treatment decision making and to improve outcomes, in patients with degenerative lumbar spine disorders pre-surgery. The aim was to describe somatosensory profiles in patients with degenerative lumbar spine disorders, to identify the proportion with altered somatosensory profile, and to analyze demographic characteristics, self-reported function, pain, and health pre- and 3 months post-surgery.

Methods

In this prospective cohort study in a Spine Clinic, 105 patients scheduled for surgery for spinal stenosis, disc herniation, degenerative disc disease, or spondylolisthesis were consecutively recruited. Exclusion criteria were; indication for acute surgery or previous surgery at the same spinal level or severe grade of pathology. Quantitative sensory testing (QST) and self-reported function, pain, and health was measured pre- and 3 months post-surgery. The somatosensory profile included cold detection threshold, warmth detection threshold, cold pain threshold, heat pain threshold and pressure pain threshold in affected and non-affected body regions.

Results

On a group level, the patients’ somatosensory profiles were within the 95% confidence interval (CI) from normative reference data means. On an individual level, an altered somatosensory profile was defined as having two or more body regions (including a non-affected region) with QST values outside of normal ranges for reference data. The 23 patients (22%) with altered somatosensory profiles, with mostly loss of function, were older (P = 0.031), more often female (P = 0.005), had higher back and leg pain (P = 0.016, 0.020), lower mental health component summary score (SF-36 MCS) (P = 0.004) and larger pain distribution (P = 0.047), compared to others in the cohort. Post-surgery there was a tendency to worse pain, function and health in the group with altered somatosensory profile pre-surgery.

Conclusions

On a group level, patients with degenerative lumbar spine disorders scheduled for surgery were within normal range for the QST measurements compared to reference values. On an individual level, an altered somatosensory profile outside of normal range in both affected and non-affected body regions occurred in 22% of patients, which may indicate disturbed somatosensory function. Those patients had mostly loss of sensory function and had worse self-reported outcome pre-surgery, compared to the rest of the cohort. Future prospective studies are needed to further examine whether these dimensions can be useful in predicting post-surgery outcome and guide need of additional treatments.

Impact of emotional distress and pain-related fear on patients with chronic pain: Subgroup analysis of patients referred to multimodal rehabilitation

OBJECTIVE

Multimodal rehabilitation programmes (MMRP) for chronic pain could be improved by determining which patients do not benefit fully. General distress and pain-related fear may explain variations in the treatment effects of MMRP.

DESIGN

Cohort study with a cross-sectional, prospective part.

PATIENTS

Chronic musculoskeletal pain patients referred to 2 hospital-based pain rehabilitation clinics.

METHODS

The cross-sectional part of this study cluster analyses patients (n = 1,218) with regard to distress and pain-related fear at first consultation in clinical pain rehabilitation and describes differences in external variables between clusters. The prospective part follows the subsample of patients (n = 260) participating in MMRP and describes outcome post-treatment.

RESULTS

Four distinct subgroups were found: (i) those with low levels of distress and pain-related fear; (ii) those with high levels of pain-related fear; (iii) those with high levels of distress; and (iv) those with high levels of distress and pain-related fear. These subgroups showed differences in demogra-phics, pain characteristics, quality of life, and acceptance, as well as the degree of MMRP participation and MMRP outcome.

CONCLUSION

Among patients with chronic pain referred to MMRP there are subgroups with different profiles of distress and pain-related fear, which are relevant to understanding the adaptation to pain and MMRP outcome. This knowledge may help us to select patients and tailor treatment for better results.

Do pain characteristics guide selection for multimodal pain rehabilitation?

OBJECTIVE

To determine whether self-reported pain measures are associated with selection for multimodal or multidisciplinary rehabilitation (MMR) and whether this selection is influenced by sex.

DESIGN

Cross-sectional cohort study.

SUBJECTS

A total of 1,226 women and 464 men with chronic pain conditions from 2 university hospitals.

METHODS

Drawing from the Swedish Quality Registry for Pain Rehabilitation (SQRP), data on pain, psychological symptoms, function, health, and activity/participation were collected. Multiple logistic regression was used to investigate association of pain measures with selection for MMR (no/yes) after multidisciplinary assessment. Covariates were: age, educational level, anxiety, depression, working status, and several pain measures.

RESULTS

High pain intensity in the previous week (odds ratio (OR) 0.92; 95% confidence interval (CI) 0.86-0.99) and high pain severity (Multidimensional Pain Inventory) (OR 0.83; 95% CI 0.74-0.95) were negatively associated with selection for MMR, whereas higher number of pain quadrants was positively associated with selection for MMR. Similar results were obtained for women, but none of the measures was predictive for men.

CONCLUSION

This practice-based study showed that higher scores on self-reported pain were not associated with selection for MMR, and in women there was a negative association for higher pain intensity and pain severity. Thus, other factors than pain determine whether patients are selected for MMR.

Association between pain sensitivity in the hand and outcomes after surgery in patients with lumbar disc herniation or spinal stenosis

PURPOSE

To investigate the association between pain sensitivity in the hand pre-surgery, and patient-reported outcomes (PROs) in function, pain and health pre- and post-surgery in patients with disc herniation or spinal stenosis.

METHODS

This is a prospective cohort study with 82 patients. Associations between pressure-, cold- and heat pain threshold (PPT, CPT, HPT) in the hand pre-surgery and Oswestry, VAS pain, EQ-5D, HADS, and Self-Efficacy Scale, pre- and three months post-surgery; were investigated with linear regression.

RESULTS

Patients with disc herniation more sensitive to pressure pain pre-surgery showed lower function and self-efficacy, and higher anxiety and depression pre-surgery, and lower function, and self-efficacy, and higher pain post-surgery. Results for cold pain were similar. In patients with spinal stenosis few associations with PROs were found and none for HPT and PROs.

CONCLUSIONS

Altered pain response in pressure- and cold pain in the hand, as a sign of widespread pain pre-surgery had associations with higher pain, lower function and self-efficacy post-surgery in patients with disc herniation.

Weak outcome predictors of multimodal rehabilitation at one-year follow-up in patients with chronic pain-a practice based evidence study from two SQRP centres

BACKGROUND

For patients with chronic pain, the heterogeneity of clinical presentations makes it difficult to identify patients who would benefit from multimodal rehabilitation programs (MMRP). Yet, there is limited knowledge regarding the predictors of MMRP's outcomes. This study identifies predictors of outcome of MMRPs at a 12-month follow-up (FU-12) based on data from the Swedish Quality Registry for Pain Rehabilitation (SQRP).

METHODS

Patients with chronic pain from two clinical departments in Sweden completed the SQRP questionnaires-background, pain characteristics, psychological symptoms, function, activity/participation, health and quality of life-on three occasions: 1) during their first visit; 2) immediately after the completion of their MMRP; and 3) 12 months after completing the MMRP (n = 227). During the FU-12, the patients also retrospectively reported their global impressions of any changes in their perception of pain and their ability to handle their life situation in general.

RESULTS

Significant improvements were found for pain, psychological symptoms, activity/participation, health, and quality of life aspects with low/medium strong effects. A general pattern was observed from the analyses of the changes from baseline to FU-12; the largest improvements in outcomes were significantly associated with poor situations according to their respective baseline scores. Although significant regressors of the investigated outcomes were found, the significant predictors were weak and explained a minor part of the variation in outcomes (15-25%). At the FU-12, 53.6% of the patients reported that their pain had decreased and 80.1% reported that their life situation in general had improved. These improvements were associated with high education, low pain intensity, high health level, and work importance (only pain perception). The explained variations were low (9-11%).

CONCLUSIONS

Representing patients in real-world clinical settings, this study confirmed systematic reviews that outcomes of MMRP are associated with broad positive effects. A mix of background and baseline variables influenced the outcomes investigated, but the explained variations in outcomes were low. There is still a need to develop standardized and relatively simple outcomes that can be used to evaluate MMRP in trials, in clinical evaluations at group level, and for individual patients.

Implementing multimodal pain rehabilitation in primary care - a health care professional perspective

PURPOSE

To explore professional perspectives on how to start and work with multimodal pain rehabilitation within primary healthcare.

METHODS

Fourteen healthcare professionals (11 women, 3 men) were individually interviewed about their experiences of starting and working with multimodal pain. Interviews were transcribed and analyzed by qualitative content analysis. This study was part of a larger project, which aimed at evaluating multimodal pain rehabilitation in primary care.

RESULTS

The analysis resulted in six categories. Two categories were about management engagement: putting the focus on rehabilitation and creating appropriate conditions. Three were about professional engagement: importance of driving spirits, creating a program - a process, and good teamwork - not a coincidence. The last category was about professional gain from multimodal rehabilitation (MMR): team work is enriching.

CONCLUSIONS

To enable implementation of MMR in primary care, managers on all organizational levels must take responsibility for allowing rehabilitation to be a priority. A driving spirit among the professionals facilitates the start, but the entire team is important when processing a program. Creating good teamwork requires hard work, e.g., negotiations for consensus about rehabilitation, and assumption of responsibility by each team member. Collaboration between professionals was perceived to strengthen and enhance knowledge about the patients. Implications for rehabilitation Much can be gained from conducting multimodal pain rehabilitation in primary care. Front line managers and those at other organizational levels must prioritize and create appropriate conditions to facilitate multimodal pain rehabilitation in primary care. Creation of an effective multimodal rehabilitation team requires that each team member takes responsibility, drops the focus on individual rehabilitation, seek member consensus about the content of the rehabilitation, and confer equal worth to each team member. The process of creating a program can be facilitated, especially at the beginning, if the team is supported by speciality pain clinics or more experienced teams.

PREPARE: Pre-surgery physiotherapy for patients with degenerative lumbar spine disorder: a randomized controlled trial protocol

Background

Current guidelines for the management of patients with specific low back pain pathology suggest non-surgical intervention as first-line treatment, but there is insufficient evidence to make recommendations of the content in the non-surgical intervention. Opinions regarding the dose of non-surgical intervention that should be trialled prior to decision making about surgery intervention vary. The aim of the present study is to investigate if physiotherapy administrated before surgery improves function, pain and health in patients with degenerative lumbar spine disorder scheduled for surgery. The patients are followed over two years. A secondary aim is to study what factors predict short and long term outcomes.

Methods

This study is a single blinded, 2-arm, randomized controlled trial with follow-up after the completion of pre-surgery intervention as well as 3, 12 and 24 months post-surgery. The study will recruit men and women, 25 to 80 years of age, scheduled for surgery due to; disc herniation, spinal stenosis, spondylolisthesis or degenerative disc disease. A total of 202 patients will be randomly allocated to a pre-surgery physiotherapy intervention or a waiting list group for 9 weeks. The waiting-list group will receive standardized information about surgery, post-surgical rehabilitation and advice to stay active. The pre-surgery physiotherapy group will receive physiotherapy 2 times per week, consisting of a stratified classification treatment, based on assessment findings. One of the following treatments will be selected; a) Specific exercises and mobilization, b) Motor control exercises or c) Traction. The pre-surgery physiotherapy group will also be prescribed a tailor-made general supervised exercise program. The physiotherapist will use a behavioral approach aimed at reducing patient fear avoidance and increasing activity levels. They will also receive standardized information about surgery, post-surgical rehabilitation and advice to stay active. Primary outcome measure is Oswestry Disability Index. Secondary outcome measures are the visual analogue scale for back and leg pain, pain drawing, health related quality of life, Hospital anxiety and depression scale, Fear avoidance beliefs questionnaire, Self-efficacy scale and Work Ability Index.

Discussion

The study findings will help improve the treatment of patients with degenerative lumbar spine disorder scheduled for surgery.

Healthcare professional experiences with patients who participate in multimodal pain rehabilitation in primary care - a qualitative study

PURPOSE

Exploring healthcare professional experiences of Multimodal rehabilitation (MMR) in primary care.

METHODS

Fourteen healthcare professionals (11 women, 3 men) were individually interviewed about their work with MMR in primary care. Interviews covered experiences of assessing patients and work with patients in the programme. Transcribed interviews were analysed by qualitative content analysis.

RESULTS

The analysis resulted in four categories: select patients for success; a multilevel challenge; ethical dilemmas and considering what is a good result. MMR work was experienced as useful and efficient, but also challenging because of patient complexity. Preconceptions about who is a suitable patient for MMR influenced the selection of patients (e.g. gender, different culture). Interviewees were conflicted about not to being able to offer MMR to patients who were not going to return to work. They thought that there were more factors to evaluate MMR than by the proportion that return to work.

CONCLUSIONS

Healthcare professionals perceive MMR as a helpful method for treating chronic pain patients. At the same time, they thought that only including patients who would return to work conflicted with their ethical views on equal healthcare for all patients. Preconceptions can influence selection for, and work with, MMR. Implications for rehabilitation Multimodal pain rehabilitation in primary healthcare is challenging because of the complexity of the patients. Healthcare professionals must deal with conflicting emotions in regard to different commitments from healthcare legislation and the goals of multimodal rehabilitation. Healthcare professionals should be aware that stereotypes regarding gender and immigrants can lead to bias when selecting patients for multimodal rehabilitation.

Evaluation of physiotherapists as primary assessors of patients with musculoskeletal disorders seeking primary health care

OBJECTIVES

To evaluate primary physiotherapist assessment and management of patients with musculoskeletal disorders in primary care, and to compare patient satisfaction with primary assessment by a physiotherapist or a general practitioner (GP).

DESIGN

An observational, retrospective cohort study reviewing medical records, and a separate consecutive non-randomised study of patient satisfaction.

SETTING

Primary healthcare centre.

PARTICIPANTS

Four hundred and thirty-two patients with musculoskeletal disorders, primarily assessed by a physiotherapist. Fifty-one of these patients primarily assessed by a physiotherapist and 42 patients assessed by a GP answered a patient satisfaction questionnaire.

INTERVENTIONS

Primary assessment and management of patients with musculoskeletal disorders.

MAIN OUTCOME MEASURES

Data from medical records within 3-month after the visit, and patient satisfaction questionnaire.

RESULTS

Eighty-five percent (367/432) of patients did not need to see a GP. Serious pathologies were found among the 6% (26/432) of patients who were referred to a GP by a physiotherapist, but no serious pathologies were found among the 9% (39/432) of patients who subsequently returned for a GP appointment for the same disorder. Patients assessed by a physiotherapist were more satisfied with the information received about their disorder and self-care than patients assessed by a GP. Patients also had higher confidence in the ability of physiotherapists to assess their disorder (P<0.002).

CONCLUSION

Physiotherapists can be considered primary assessors of patients with musculoskeletal disorders in primary care as few patients needed additional assessment by a GP, patients with confirmed serious pathologies were identified by the physiotherapists, and patients were satisfied with assessment by a physiotherapist.

Predictive factors for 1-year and 5-year outcome for disability in a working population of patients with low back pain treated in primary care

Many patients seeking primary care for low back pain continue to report disability several years after their initial visit. The aims of this study were to assess the independent predictive value of a number of potential predictive factors for disability at the 1-year and 5-year follow-ups, and to examine whether prediction models were improved by replacing baseline health-state-related variables with corresponding variables after treatment. A further aim was to describe possible differences between those on sick leave, early retirement or disability pension, and those who were not. Baseline factors were age, gender, self-reported physical-activity-related and work-related factors, expectations of treatment, similar problems previously, duration of episode, more than one localization, sick leave, pain frequency, disability, and well-being. The study sample comprised 148 participants in a previous randomized trial who were eligible for sick-leave benefits. Multiple logistic regression was used to identify predictive factors. At the 5-year follow-up, 37% (n=19/52) of the patients with disability were on sick leave or were receiving early retirement or disability pension. For those without disability the corresponding figure was 9% (n=8/92). Being a woman, duration of the current episode, similar problems during the previous 5 years, exercise level before the current episode, pain frequency at baseline, and disability after treatment emerged as predictive factors for disability at the 5-year follow-up. Replacing baseline health-state-related measures with corresponding measures after the treatment period, and adding physical-activity-related and possibly work-related factors might improve the likelihood of predicting future disability.

Clinical course in patients seeking primary care for back or neck pain: a prospective 5-year follow-up of outcome and health care consumption with subgroup analysis

STUDY DESIGN

Prospective follow-up.

OBJECTIVE

To describe the 5-year clinical course in a cohort of patients treated for back or neck pain in primary care and compare results with the 1-year outcome both for the whole group and for subgroups.

SUMMARY OF BACKGROUND DATA

A randomized study showed a decrease in perceived pain and disability after treatment by chiropractic or physiotherapy, but many reported recurrence or continual pain at the 1-year follow-up. Knowledge of the clinical course over longer follow-up periods is limited.

METHODS

A 5-year follow-up questionnaire was sent to 314 individuals. Main outcome measures were pain intensity, Oswestry score, and general health. Recurrence, health care consumption, and other measures were described.

RESULTS

Fifty-two percent of respondents reported pain (visual analog scale, >10 mm) and back-related disability (Oswestry, >10%) at the 5-year follow-up. This was similar to 1-year results, and 84% of these were the same individuals. Sixty-three percent reported recurrence or continual pain, and 32% reported health care consumption at the 5-year follow-up.

CONCLUSIONS

In a cohort of individuals of working age seeking primary care for nonspecific back or neck pain, it can be expected that about half of the population will report pain and disability at the 5-year follow-up. A significant proportion will report recurrence or continual pain and health care consumption. Pain and disability were associated with recurrence or continual pain and health care consumption. Further analysis is needed to identify additional predictors for 5-year outcome, taking into account 1-year follow-up results. Since many patients will have recurrence or continual pain, health policies and clinical decision models for long-term outcome must allow for these aspects.

Course of back pain in primary care: a prospective study of physical measures

OBJECTIVE

To describe physical measures used in patients with back pain when no specific treatment is given, to examine associations between change over time in these measures and changes in pain and back-related disability, and to study the value of physical measures at baseline and at a 4-week follow-up to predict outcome at 12 months.

DESIGN

A prospective consecutive study.

SUBJECTS

Forty-four patients presenting with low back pain in primary care.

METHODS

The patients underwent a physical examination at baseline and at 4 weeks. Follow-up was carried out using questionnaires until 12 months. Linear regression was used to identify predictors.

RESULTS

Most measures had improved significantly at the 4-week follow-up. Thoracolumbar rotation, isometric endurance back extensors, and fingertip-to-floor distance at 4 weeks were significant predictors for pain intensity and back-related disability at the 12-month follow-up. Eighteen out of 44 patients reported an increase in pain after the assessment of the physical measures at baseline. This group of patients improved more in physical measures between baseline and the 4-week follow-up.

CONCLUSION

Physical measures assessed at the 4-week follow-up, but not at baseline, could provide important additional information for identifying those patients at risk for worse outcome in pain or back-related disability at 12 months.

Studies on the efficacy of hyperbaric rendering procedures in inactivating bovine spongiform encephalopathy (BSE) and scrapie agents

The efficacy of the procedures in use at the two rendering plants in the Netherlands was assessed on a laboratory-scale using procedures that simulated the pressure cooking part of the rendering process. A pool of bovine spongiform encephalopathy (BSE)-infected brainstem from the United Kingdom and a pool of scrapie-infected brainstem from Dutch sheep were used to spike the rendering materials. The mixtures were subjected to various time-temperature combinations of hyperbaric heat treatment related to the conditions used in Dutch rendering plants in the early 1990s, and to the combination of 20 minutes at 133 degrees C required by the EU Directive on rendering of 1996. The efficacy of the procedures in inactivating BSE or scrapie infectivity was measured by titrating the materials before and after heat treatment in inbred mice, by combined intracerebral and intraperitoneal inoculations at limiting dilutions. Two independent series of experiments were carried out. The design of the study allowed for minimum inactivations of up to 2.2 log (2.0 in the second series) to be measured in the diluted infective material and 3.1 log in the undiluted material. After 20 minutes at 133 degrees C there was a reduction of BSE infectivity of about 2.2 log in the first series (with some residual infectivity detected), and in the second series more than 2.0 log (with no residual infectivity detected). With undiluted brain material there was an inactivation of about 3.0 log (with some residual infectivity detected). With the same procedure, scrapie infectivity was reduced by more than 1.7 log in the first series and by more than 2.2 log in the second series. With undiluted brain material there was an inactivation of more than 3.1 log. In each case no residual scrapie infectivity was detected. The BSE agent consistently appeared to be more resistant to heat inactivation procedures than the scrapie agent, particularly at lower temperatures and shorter times.
