Distinctiveness of psychological obstacles to recovery in low back pain patients in primary care

The Role of Self-Efficacy on the Prognosis of Chronic Musculoskeletal Pain: A Systematic Review

Evidence suggests that self-efficacy can play an essential role as a protective factor as well as a mediator in the relationship between pain and disability in people suffering from chronic musculoskeletal pain. This study systematically reviewed and critically appraised the role of self-efficacy on the prognosis of chronic musculoskeletal pain. Study selection was on the basis of longitudinal studies testing the prognostic value of self-efficacy in chronic musculoskeletal pain. The Newcastle-Ottawa Scale, the Cochrane Collaboration's tool, and the Methodological Index for Non-Randomized Studies checklist were used to evaluate the risk of bias of included studies. A total of 27 articles met the inclusion criteria. Our results suggest that higher self-efficacy levels are associated with greater physical functioning, physical activity participation, health status, work status, satisfaction with the performance, efficacy beliefs, and lower levels of pain intensity, disability, disease activity, depressive symptoms, presence of tender points, fatigue, and presenteeism. Despite the low quality of evidence of included studies, clinicians should be encouraged identify people with chronic musculoskeletal pain who present low self-efficacy levels before prescribing any therapy. It may help clinicians in their clinical decision-making and timely and specific consultations with-or referral to-other health care providers.

PERSPECTIVE

This article presents promising results about the role of self-efficacy on the prognosis of chronic musculoskeletal pain. However, because of the low quality of evidence of included studies, these findings should be taken with caution, and further research is needed.

Biopsychosocial factors associated with chronic low back pain disability in rural Nigeria: a population-based cross-sectional study

Introduction

Many people in Nigeria are living with disability due to chronic low back pain (CLBP), with the greatest burden accounted for by people living in rural Nigeria. However, factors associated with disability in rural Nigeria have not yet been established. We investigated the biomechanical and psychosocial predictors of CLBP disability in a rural Nigerian population.

Methods

A cross-sectional study of adults with non-specific CLBP recruited from rural communities in Enugu State, South-eastern Nigeria. Measures of self-reported and performance-based disability, pain intensity, anxiety and depression, coping strategies, social support, occupational biomechanical factors, illness perceptions and fear avoidance beliefs were collected by trained community health workers. We used univariate and multivariate analyses.

Results

200 individuals were recruited. Psychosocial factors were the most important factors associated with CLBP disability, and accounted for 62.5% and 49.1% of the variance in self-reported and performance-based disability, respectively. The significant predictors of self-reported disability were: illness perceptions (β=0.289; p<0.0005), pain intensity (β=0.230; p<0.0005), catastrophising (β=0.210; p=0.001), fear avoidance beliefs (β=0.198; p=0.001) and anxiety (β=0.154; p=0.023). The significant predictors of performance-based disability were: illness perceptions (β=0.366; p<0.0005), social support (β=0.290; p<0.0005), fear avoidance beliefs (β=0.189; p<0.01) and female gender (β=0.184; p<0.01). Illness concern was the most salient dimension of illness perceptions predicting self-reported and performance-based disability.

Conclusions

These results provide evidence which can be used to inform the development of interventions to reduce CLBP disability in rural Nigeria, and may have relevance in other rural African contexts.

Explaining How Cognitive Behavioral Approaches Work for Low Back Pain: Mediation Analysis of the Back Skills Training Trial

STUDY DESIGN

This is secondary research examining the longitudinal mediation effect within a structural equation model.

OBJECTIVE

To identify possible mechanisms that mediate the effects of a cognitive behavioral approach upon disability and pain in low back pain patients.

SUMMARY OF BACKGROUND DATA

Cognitive behavioral interventions (CBIs) can improve pain and disability in low back pain (LBP) but the mechanisms of action are unclear. We used data from a large randomized controlled trial to investigate mediators of the treatment effect of CBI.

METHODS

Pain self-efficacy, fear avoidance, and physical and mental functioning were selected as candidate mediators based on the theoretical rationale of the intervention. The primary treatment outcomes were the Roland Morris Questionnaire (RMDQ) and the modified Von Korff scale (MVK pain and disability) at 12 months. We used structural equation models to estimate the contribution of mediators. All models were tested for goodness-of-fit using χ , Root Mean Square Error of Approximation, Adjusted Goodness of Fit Index, and Bentler Comparative Fit Index.

RESULTS

We included 701 adults with LBP. The average RMDQ score at baseline for those on the intervention arm was 8.8 (Standard Deviation 5.0). The intervention was effective in reducing disability and pain at 12 months. Change in mental functioning was not a significant mediator. Changes to pain self-efficacy, fear avoidance, and physical functioning were causal mediators of the treatment effect at 12 months (RMDQ b= -0.149, P < 0.001; MVK-pain b = -0.181, P < 0.001 and MVK-disability b = -0.180, P < 0.001). Overall, the SEM model exceeded the threshold for acceptable goodness-of-fit.

CONCLUSION

Fear avoidance and self-efficacy were important causal mediators of the cognitive behavioral treatment effect. Self-assessed change in physical function was a causal mediator but mental functioning was not. This suggests people need to experience meaningful change in physical function and beliefs but not in mental functioning associated with LBP, to achieve a treatment benefit.

The Optimal Screening for Prediction of Referral and Outcome (OSPRO) in patients with musculoskeletal pain conditions: a longitudinal validation cohort from the USA

PURPOSE

There is an increased need for determining which patients with musculoskeletal pain benefit from additional diagnostic testing or psychologically informed intervention. The Optimal Screening for Prediction of Referral and Outcome (OSPRO) cohort studies were designed to develop and validate standard assessment tools for review of systems and yellow flags. This cohort profile paper provides a description of and future plans for the validation cohort.

PARTICIPANTS

Patients (n=440) with primary complaint of spine, shoulder or knee pain were recruited into the OSPRO validation cohort via a national Orthopaedic Physical Therapy-Investigative Network. Patients were followed up at 4 weeks, 6 months and 12 months for pain, functional status and quality of life outcomes. Healthcare utilisation outcomes were also collected at 6 and 12 months.

FINDINGS TO DATE

There are no longitudinal findings reported to date from the ongoing OSPRO validation cohort. The previously completed cross-sectional OSPRO development cohort yielded two assessment tools that were investigated in the validation cohort.

FUTURE PLANS

Follow-up data collection was completed in January 2017. Primary analyses will investigate how accurately the OSPRO review of systems and yellow flag tools predict 12-month pain, functional status, quality of life and healthcare utilisation outcomes. Planned secondary analyses include prediction of pain interference and/or development of chronic pain, investigation of treatment expectation on patient outcomes and analysis of patient satisfaction following an episode of physical therapy.

TRIAL REGISTRATION NUMBER

The OSPRO validation cohort was not registered.

The impact of psychological factors on condition-specific, generic and individualized patient reported outcomes in low back pain

Background

An individualized patient reported outcome (PRO) has recently been recommended within LBP research, but no study has evaluated this instrument with commonly applied PROs. Moreover, the impact of psychological factors has mostly been assessed for disease-specific instruments. The objective of this study was to assess the predictive value of illness perceptions, pain catastrophizing and psychological distress on 12 month outcomes assessed by specific, generic and individualized PROs recommended in low back pain (LBP).

Methods

Secondary analysis of patients with sub-acute or chronic LBP recruited for a cluster randomized controlled trial in primary care who completed a self-administered questionnaire at baseline and 12 months. 12 month scores for the Roland Morris Disability Questionnaire (RMDQ), the EuroQol (EQ-5D), and the Patient Generated Index (PGI) were dependent variables in hierarchical regression analysis. Independent variables included baseline scores for the Brief Illness Perceptions Questionnaire (Brief IPQ), Hopkins Symptom Check List (HSCL-25), Pain Catastrophizing Scale (PCS), health/clinical and sociodemographic variables.

Results

Of the 216 eligible patients included, 203 patients responded to the baseline questionnaire and 150 (74%) responded at 12 months. The mean age was 38.3 (SD 10.2) years and 57.6% were female. The Brief IPQ showed a statistically significant variation in the 12-months score of all the PROs, explaining 2.5% in RMDQ, 7.9% in EQ-5D, and 3.6% in PGI. Most of the explained variation for EQ-5D scores related to illness perceptions. The PCS explained 3.7% of the RMDQ and 2.5% in the EQ-5D scores. The HSCL-25 did not make a significant contribution.

Conclusion

Illness perceptions and pain catastrophizing were associated with 12-month outcomes as assessed by condition-specific, generic and individualized PROs. The Brief IPQ and PCS have relevance to applications in primary care that include interventions designed to enhance psychological aspects of health and where the contribution of such variables to outcomes is of interest. Further studies should assess whether the Brief IPQ perform similarly in LBP populations in other health care settings.

Inter-Professional Practices of Private-Sector Physiotherapists for Low Back Pain Management: Who, How, and When?

Purpose: Although there have been increasing demands for health care providers to take part in inter-professional practices in recent years, very little attention has been paid to the actualization of such practices in the private sector. This study describes private-sector physiotherapists' inter-professional practices regarding low back pain (LBP) management and identifies organizational and provider-level variables associated with the intensity of such practices. Method: A total of 327 randomly selected physiotherapists were surveyed in the province of Quebec. Data were analyzed using descriptive and multiple regression analyses. Results: Physiotherapists reported frequent interactions with other physiotherapists (daily/weekly for 52.6%), family physicians (51.0%), and physiotherapy (PT) assistants (45.2%), but infrequent interactions with psychologists (3.6%), neurosurgeons (0.9%), and chiropractors (0.3%). Frequently reported means of interactions were written and oral messages sent through clients (55.1% and 24.1%, respectively), face-to-face unplanned discussions (41.9%), and faxed or mailed letters (23.2%). Variables associated with the intensity of inter-professional practices (mean of 6.7 [SD 1.7] out of 10 on the Intensity of Interprofessional Practices Questionnaire for Private Sector Physiotherapists) were related to physiotherapists' clientele, social activities with other providers, and perceptions of inter-professional practices as well as organizational models, vision, and provision of PT training. Conclusions: There is room to improve inter-professional practices with private-sector physiotherapists involved in managing LBP. Targets for action include physiotherapists and their workplaces.

Factors associated with attitudes and beliefs of elders with acute low back pain: data from the study Back Complaints in the Elders (BACE)

Background

The attitudes and beliefs that older people have about acute low back pain (LBP) may influence the coping mechanisms and the adoption of treatment strategies in this population.

Objective

The aim of this study was to identify the factors associated with the attitudes and beliefs of elderly patients with acute low back pain using the Back Beliefs Questionnaire.

Method

This is a cross-sectional study with a subsample of the study “Back Complaints in the Elders” (BACE), composed of 532 older Brazilians of both genders with acute LBP. We investigated sociodemographic and clinical aspects, self-perceived health, psychosocial and emotional state, falls, and functional capacity. Multiple regression models were constructed to measure possible associations.

Results

The percentage of female participants was 85.7% and the mean age was 69.04 (SD=6.2). Disability, symptoms of depression, and expectation of return to activities were independently associated with attitudes and beliefs concerning LBP.

Conclusion

Screening of psychosocial factors is essential to the prevention of persistent and recurrent LBP. Early signs of these factors can help identify symptoms and behaviors for effective interventions.

Alexander Technique Training Coupled With an Integrative Model of Behavioral Prediction in Teachers With Low Back Pain

BACKGROUND

Individuals suffering from chronic low back pain (CLBP) experience major physical, social, and occupational disruptions. Strong evidence confirms the effectiveness of Alexander technique (AT) training for CLBP.

OBJECTIVES

The present study applied an integrative model (IM) of behavioral prediction for improvement of AT training.

METHODS

This was a quasi-experimental study of female teachers with nonspecific LBP in southern Tehran in 2014. Group A contained 42 subjects and group B had 35 subjects. In group A, AT lessons were designed based on IM constructs, while in group B, AT lessons only were taught. The validity and reliability of the AT questionnaire were confirmed using content validity (CVR 0.91, CVI 0.96) and Cronbach's α (0.80). The IM constructs of both groups were measured after the completion of training. Statistical analysis used independent and paired samples t-tests and the univariate generalized linear model (GLM).

RESULTS

Significant differences were recorded before and after intervention (P < 0.001) for the model constructs of intention, perceived risk, direct attitude, behavioral beliefs, and knowledge in both groups. Direct attitude and behavioral beliefs in group A were higher than in group B after the intervention (P < 0.03).

CONCLUSIONS

The educational framework provided by IM for AT training improved attitude and behavioral beliefs that can facilitate the adoption of AT behavior and decreased CLBP.

The Relationship between Pain Beliefs and Physical and Mental Health Outcome Measures in Chronic Low Back Pain: Direct and Indirect Effects

Low back pain remains a major health problem with huge societal cost. Biomedical models fail to explain the disability seen in response to reported back pain and therefore patients’ beliefs, cognitions and related behaviours have become a focus for both research and practice. This study used the Pain Beliefs Questionnaire and had two aims: To examine the extent to which pain beliefs are related to disability, anxiety and depression; and to assess whether those relationships are mediated by pain self-efficacy and locus of control. In a sample of 341 chronic low back pain patients, organic and psychological pain beliefs were related to disability, anxiety and depression. However, organic pain beliefs were more strongly related to disability and depression than psychological pain beliefs. Regression analyses revealed that these relationships were in part independent of pain self-efficacy and locus of control. Further, mediation analyses revealed indirect pathways involving self-efficacy and, to a lesser extent chance locus of control, between organic pain beliefs, on the one hand, and disability, anxiety and depression, on the other. In contrast, psychological pain beliefs were only directly related to disability, anxiety and depression. Although longitudinal data are needed to corroborate our findings, this study illustrates the importance of beliefs about the nature of pain and beliefs in one’s ability to cope with pain in determining both physical and mental health outcomes in chronic low back pain patients.

Prevalence of anxiety, depression and kinesiophobia in patients with low back pain and their association with the symptoms of low back spinal pain

OBJECTIVE

To evaluate the prevalence of anxiety, depression and kinesiophobia and their association with the symptoms of low back pain.

METHODS

A total of 65 patients were divided into three groups: Organic, Amplified Organic and Non-Organic. They answered the Beck Anxiety Inventory, Beck Depression Inventory and Tampa Scale of Kinesiophobia and were evaluated according to their pain level using the Visual Analogic Scale.

RESULTS

The average kinesiophobia scores of the patients in the Organic, Amplified Organic and Non-Organic groups were 36.26, 36.21 and 23.06 points, respectively. Patients who were classified into the Organic group experienced the most kinesiophobia out of all three groups (p=0.007). The average anxiety scores of the patients in the Organic, Amplified Organic and Non-Organic groups were 33.17, 32.79 and 32.81 points, respectively, with no significant difference among the groups (p=0.99). The average depression scores of the patients in the Organic, Amplified Organic and Non-Organic groups were 32.54, 28.79 and 37.69 points, respectively, with no significant difference among the groups (p=0.29).

CONCLUSION

There was no association between the groups and anxiety and depression. However, there was a positive correlation between kinesiophobia and the Organic group. Studies of other patient samples are needed to confirm the reproducibility and validity of these data in other populations.

Preliminary Evaluation of a Modified STarT Back Screening Tool Across Different Musculoskeletal Pain Conditions

BACKGROUND

The STarT Back Screening Tool is a validated multidimensional screening measure and risk stratification tool for people with low back pain.

OBJECTIVE

The study objective was to compare relationships between a modified STarT Back Screening Tool (mSBT) and clinical and psychological measures in people with low back, neck, shoulder, and knee pain. The hypothesis was that the relationships between mSBT scores and clinical and psychological measure scores would be similar across the included musculoskeletal pain conditions.

DESIGN

A cross-sectional, secondary analysis was done in this study.

METHODS

Participants with low back (n=118), neck (n=92), shoulder (n=106), or knee (n=111) pain were recruited, and an mSBT was developed for use across the pain conditions. Separate hierarchical linear regression models were developed, with clinical (health status, pain intensity, and disability) and psychological (kinesiophobia, catastrophizing, fear avoidance, anxiety, depressive symptoms, and self-efficacy) measures as dependent variables. Demographic and pain region variables were entered in the first step, mSBT scores were entered in the second step, and pain region × mSBT interactions were entered in the last step.

RESULTS

In the final models, no interactions were identified, suggesting that dependent measure scores did not differ by pain region. The strongest contributor for all dependent variables was mSBT scores (β=|0.32|-|0.68|); higher mSBT scores were associated with poorer health status and self-efficacy and with higher levels of pain intensity, disability, kinesiophobia, catastrophizing, fear avoidance, anxiety, and depressive symptoms.

LIMITATIONS

Generalizability was restricted to physical therapy outpatients with the included pain conditions. The mSBT used in this study is not ready for clinical implementation.

CONCLUSIONS

The results of this study support the feasibility of using a single measure for concise risk assessment across different musculoskeletal pain conditions. Further longitudinal studies are needed to better direct the clinical use of an mSBT in people with low back, neck, shoulder, and knee pain.

Can physical therapy centred on cognitive and behavioural principles improve pain self-efficacy in symptomatic lumbar isthmic spondylolisthesis? A case series

PURPOSE

Pain-related self-efficacy is defined as "the beliefs held by people with chronic pain that were able to carry out certain activities, even when experiencing pain", and it is considered a relevant mediator in the relationship between pain and disability in chronic low back pain. This case series describes a treatment aiming to improve pain self-efficacy in patients with symptomatic lumbar spondylolisthesis.

METHOD

Ten consecutive outpatients with lumbar spondylolisthesis and chronic LBP referred to a rehabilitative clinic participated in this study. Cognitive and behavioural principles were integrated with functional and graded approach in each individual physical therapy program. The outcome measures concerned clinical instability and endurance tests, pain, disability and self-efficacy.

RESULTS

Pain self-efficacy and lumbar function improved in 7 out of 10 patients; clinical tests improved in 9 out of 10 patients.

CONCLUSION

A rehabilitation program carried out by a physical therapist, centred on cognitive and behavioural principles, appeared useful in improving pain self-efficacy and lumbar function. These results may be interesting for future controlled trials.

Patients with neck pain are less likely to improve if they experience poor sleep quality: a prospective study in routine practice

OBJECTIVE

To assess whether sleep quality (SQ) at baseline is associated with improvement in pain and disability at 3 months.

MATERIALS AND METHODS

Four hundred twenty-two subacute and chronic patients with neck pain (NP) were recruited in 32 physiotherapy, primary care, and specialized centers. NP, referred pain, disability, catastrophizing, depression, and SQ were assessed through validated questionnaires, upon recruitment and 3 months later. Correlations between baseline scores were calculated through the Spearman coefficient. Improvements in NP, disability, and SQ were defined as a reduction of ≥30% of baseline score. Six estimative logistic regression models were developed to assess the association between baseline SQ and improvement of NP, baseline SQ and improvement of disability, baseline NP and improvement of SQ, baseline disability and improvement of SQ, the evolutions of NP and SQ, and the evolutions of disability and SQ.

RESULTS

Most patients were subacute and mildly impaired. Regression models showed that better SQ at baseline was associated with improvement of NP (odds ratio=0.91 [95% confidence interval, 0.83-0.99]), but not disability (1.04 [0.95-1.13]); the improvement of SQ was associated with more severe NP at baseline (1.26 [1.07-1.49)], but not with baseline disability (0.99 [0.97-1.02]); and that improvement in SQ was associated with improvements in NP (3.48 [1.68-7.20]), and disability (5.02 [2.39-10.11]).

DISCUSSION

NP is less likely to improve in patients with poorer SQ, irrespective of age, sex, catastrophizing, depression, or treatments prescribed for NP. Future studies should confirm these results with more severely impaired patients.

Responsiveness and Minimal Important Change of the Pain Self-Efficacy Questionnaire and Short Forms in Patients With Chronic Low Back Pain

The Pain Self-Efficacy Questionnaire (PSEQ) is a valid and reliable patient-reported instrument used to assess pain self-efficacy in patients with chronic low back pain (CLBP). Recently, the 2-item (PSEQ-2) and the 4-item (PSEQ-4) short versions were developed showing satisfactory measurement properties in mixed populations with chronic pain. The aim of this study was to examine responsiveness and minimal important change (MIC) of PSEQ, PSEQ-2, and PSEQ-4 in patients with CLBP. We used a sample of 104 patients undergoing multimodal physical therapy designed to partly change pain self-efficacy beliefs. Responsiveness was assessed by testing 16 a priori formulated hypotheses regarding effect sizes, areas under the curve, and correlations with changes in other instruments measuring other constructs. The MIC was calculated using an external anchor specific for pain self-efficacy and the receiver operator characteristic (ROC) method. The PSEQ and the PSEQ-4 met all hypotheses, whereas the PSEQ-2 met all but 1. The MICs were 5.5 for the PSEQ (9% of the scale range) and 1.5 for PSEQ-2 (13% scale range) and PSEQ-4 (6% scale range). MIC values were different for patients with low or high baseline values for all 3 instruments. The PSEQ and its short versions are adequately responsive instruments in patients with CLBP.

PERSPECTIVE

This study suggests that the PSEQ and its short versions are responsive measures of pain self-efficacy in patients with CLBP, adding to previous literature on their validity and reliability. Considering their similar responsiveness, the 4-item PSEQ could replace the original 10-item version in busy clinical or research settings.

A practical tool to improve outcomes in Work Injury Management

BACKGROUND

Psychosocial factors have the greatest influence on work rehabilitation outcomes yet effective and efficient systems to manage these factors are not widely utilized in Work Injury Management.

OBJECTIVE

To report on the development and validation of a comprehensive assessment tool with practical utility in identifying and measuring the biopsychosocial factors which are barriers to return to work and community.

METHODS

Literature search identified many instruments designed to identify the presence of psychosocial factors impacting recovery and return to work following musculoskeletal injury. This research aimed to match assessment with intervention. In clinical practice over a 5 year period, this led to development of a composite questionnaire, the Abilita Rehabilitation Index, which was trialed with 43 adults participating in Occupational Rehabilitation. The validation data are based on the results of 957 case records of Occupational Rehabilitation participants.

RESULTS

Examination of Cronbach coefficient alpha of the instrument indicates strong internal consistency (0.90) and factor analysis supports satisfactory construct validity of the domains (subscales) with factor loading scores ranging from 0.73 to 0.90.

CONCLUSION

There is evidence that the proprietary Abilita Rehabilitation Index is a valid and reliable instrument to identify and measure the influence of psychosocial factors impacting an individual's recovery and return to work. Automated reports generated from this tool provide an evidence-based resource to identify risk and support rehabilitation planning in Work Injury Management.

Prevalence of anxiety, depression and kinesiophobia in patients with low back pain and their association with the symptoms of low back spinal pain

OBJECTIVE

To evaluate the prevalence of anxiety, depression and kinesiophobia and their association with the symptoms of low back pain.

METHODS

A total of 65 patients were divided into three groups: Organic, Amplified Organic and Non-Organic. They answered the Beck Anxiety Inventory, Beck Depression Inventory and Tampa Scale of Kinesiophobia and were evaluated according to their pain level using the Visual Analogic Scale.

RESULTS

The average kinesiophobia scores of the patients in the Organic, Amplified Organic and Non-Organic groups were 36.26, 36.21 and 23.06 points, respectively. Patients who were classified into the Organic group experienced the most kinesiophobia out of all 3 groups (p=0.007). The average anxiety scores of the patients in the Organic, Amplified Organic and Non-Organic groups were 33.17, 32.79 and 32.81 points, respectively, with no significant difference among the groups (p=0.99). The average depression scores of the patients in the Organic, Amplified Organic and Non-Organic groups were 32.54, 28.79 and 37.69 points, respectively, with no significant difference among the groups (p=0.29).

CONCLUSION

There was no association between the groups and anxiety and depression. However, there was a positive correlation between kinesiophobia and the Organic group. Studies of other patient samples are needed to confirm the reproducibility and validity of these data in other populations.

Strategies for Coping with Chronic Lower Back Pain in Patients with Long Physiotherapy Wait Time

BACKGROUND Treatment efficacy for the increasing prevalence of back pain is a great challenge for both health care providers and individuals coping with this problem. This study aimed to evaluate pain coping strategies used by primary care patients with chronic lower back pain (CLBP) as a supplementation of medical diagnosis before a physiotherapy programme. MATERIAL AND METHODS A total of 88 people were divided into 3 age groups: young adults (21-40 years old), middle-aged adults (41-60 years old), and the elderly (over 60 years old). Data was gathered from rehabilitation centers and primary medical care facilities. A cross-sectional design was used. The Coping Strategies Questionnaire (CSQ) was completed before the physiotherapy course. RESULTS Patients complained of CLBP for 11.32±6.81 years on average. The most common strategies to cope with back pain included declaring that the pain is manageable, praying and hoping, as well as increased behavioral activity. Statistically significant differences in coping strategies were found between age groups. The elderly patients were more likely to "declare coping with pain" in comparison to the younger age groups (p<0.01). People over 60 years of age were more likely to declare active coping with pain, while young people reported catastrophizing. CONCLUSIONS Patients in different age groups had various difficulties in pain coping. Most of them required support in self-management of pain in addition to physiotherapy. The basic assessment of pain coping strategies should be consistently taken into account and included in rehabilitation protocols in chronic pain treatment.

Psychological covariates of longitudinal changes in back-related disability in patients undergoing acupuncture

Supplemental Digital Content is available in the text.

Objectives:

To identify psychological covariates of longitudinal changes in back-related disability in patients undergoing acupuncture.

Materials and Methods:

A longitudinal postal questionnaire study was conducted with data collection at baseline (pretreatment), 2 weeks, 3, and 6 months later. A total of 485 patients were recruited from 83 acupuncturists before commencing acupuncture for back pain. Questionnaires measured variables from 4 theories (fear-avoidance model, common-sense model, expectancy theory, social-cognitive theory), clinical and sociodemographic characteristics, and disability. Longitudinal multilevel models were constructed with disability over time as the outcome.

Results:

Within individuals, reductions in disability (compared with the person’s individual mean) were associated with reductions in: fear-avoidance beliefs about physical activity (β=0.11, P<0.01) and work (β=0.03, P<0.05), catastrophizing (β=0.28, P<0.05), consequences (β=0.28, P<0.01), concerns (β=0.17, P<0.05), emotions (β=0.16, P<0.05), and pain identity (β=0.43, P<0.01). Within-person reductions in disability were associated with increases in: personal control (β=−0.17, P<0.01), comprehension (β=−0.11, P<0.05) and self-efficacy for coping (β=−0.04, P<0.01). Between individuals, people who were less disabled had weaker fear-avoidance beliefs about physical activity (β=0.12, P<0.01), had more self-efficacy for coping (β=−0.07, P<0.01), perceived less severe consequences of back pain (β=0.87, P<0.01), had more positive outcome expectancies (β=−0.30, P<0.05), and appraised acupuncture appointments as less convenient (β=0.92, P<0.05).

Discussion:

Illness perceptions and, to a lesser extent, self-efficacy and expectancies can usefully supplement variables from the fear-avoidance model in theorizing pain-related disability. Positive changes in patients’ beliefs about back pain might underpin the large nonspecific effects of acupuncture seen in trials and could be targeted clinically.

Pain Self-Efficacy and Fear of Movement are Similarly Associated with Pain Intensity and Disability in Italian Patients with Chronic Low Back Pain

The purpose of this study was to investigate cross-sectional associations of pain self-efficacy and fear of movement with pain intensity and disability in Italian patients with chronic low back pain (CLBP). One hundred and three adult outpatients with nonspecific CLBP were included in the study. Socio-demographic and clinical characteristics were assessed, together with Italian versions of self-reported questionnaires to measure the four constructs of interest. Multiple linear regression models were built with psychosocial constructs as main determinants, and pain intensity and disability as outcomes. Potential confounding of socio-demographic and clinical characteristics was assessed. Pain self-efficacy and fear of movement displayed moderate correlations with pain intensity (r = -0.41 and 0.42, respectively) and disability (-0.55 and 0.54). Association models adjusted for pain intensity showed that both pain self-efficacy (β = -0.35, 95% CI = -0.5; -0.2, R²  = 41%) and fear of movement (β = 0.65, 95% CI = 0.36; 0.93, R²  = 40%) are significantly and strongly associated with disability. Pain self-efficacy was no longer significantly associated with pain intensity when disability was added as a confounder to the model, whereas fear of movement retained its significant association (β = 0.06, 95% CI = 0.00;0.11, R²  = 30%). No other variables acted as confounders in these associations. Pain self-efficacy and fear of movement are very similarly associated with main outcomes in this sample of Italian patients with CLBP. The results of this study suggest that both psychosocial constructs should be considered in clinical management. Future studies should investigate whether these findings can be replicated in other samples, in longitudinal designs and if other variables not measured in this study confound the associations.

The accuracy of pain drawing in identifying psychological distress in low back pain-systematic review and meta-analysis of diagnostic studies

The aim of this systematic review and meta-analysis was to estimate the accuracy of qualitative pain drawings (PDs) in identifying psychological distress in subacute and chronic low back pain (LBP) patients. [Subjects and Methods] Data were obtained from searches of PubMed, EBSCO, Scopus, PsycINFO and ISI Web of Science from their inception to July 2014. Quality assessments of bias and applicability were conducted using the Quality of Diagnostic Accuracy Studies-2 (QUADAS-2). [Results] The summary estimates were: sensitivity=0.45 (95% CI 0.34, 0.61), specificity=0.66 (95% CI 0.53, 0.82), positive likelihood ratio=1.23 (95% CI 0.93, 1.62), negative likelihood ratio=0.84 (95% CI 0.70, 1.01), and diagnostic odds ratio=1.46 (95% CI 0.79, 2.68). The area under the curve was 78% (CI, 57 to 99%). [Conclusion] The results of this systematic review do not show broad and unqualified support for the accuracy of PDs in detecting psychological distress in subacute and chronic LBP.

A Functional Magnetic Resonance Imaging Study to Investigate the Utility of a Picture Imagination Task in Investigating Neural Responses in Patients with Chronic Musculoskeletal Pain to Daily Physical Activity Photographs

Pain-related anxiety and fear are associated with increased difficulties in attention, increased awareness of pain, impaired disengagement from pain, and can moderate the effects of attentional coping attempts. Accurately assessing the direct impact of pain-related anxiety and fear on pain behavior has proved difficult. Studies have demonstrated no or limited influence of pain-related fear and anxiety on behavior but this may be due to inherent problems with the scales used. Neuroimaging has improved the understanding of neural processes underlying the factors that influence pain perception. This study aimed to establish if a Picture and Imagination Task (PIT), largely developed from the Photographs of Daily Activity (PHODA) assessment tool, could help explore how people living with chronic pain process information about daily activities. Blood oxygenation level dependent (BOLD) functional magnetic resonance imaging (fMRI) was used to compare brain responses in patients with chronic musculoskeletal pain (CMSKP) (n = 15) and healthy controls (n = 15). Subjects were asked to imagine how they would feel mentally and physically if asked to perform daily activities illustrated in PIT. The results found that a number of regions involved in pain processing saw increased BOLD activation in patients compared with controls when undertaking the task and included the insula, anterior cingulate cortex, thalamus and inferior and superior parietal cortices. Similarly, increased BOLD responses in patients compared to controls in the frontal pole, paracingulate and the supplementary motor cortex may be suggestive of a memory component to the responses The amygdala, orbitofrontal cortex, substantia nigra/ventral tegmentum, putamen, thalamus, pallidum, inferior parietal (supramarginal and angular gyrus) and cingulate cortex were also seen to have greater differences in BOLD signal changes in patients compared with controls and many of these regions are also associated with general phobic responses. Therefore, we suggest that PIT is a useful task to explore pain- and movement-related anxiety and fear in fMRI studies. Regions in the Default Mode Network remained active or were less deactivated during the PIT task in patients with CMSKP compared to healthy controls supporting the contention that the DMN is abnormal in patients with CMSKP.

The reciprocal effect of pain catastrophizing and satisfaction with participation in the multidisciplinary treatment of patients with chronic back pain

Background

The aim of the study was to examine the reciprocity between pain catastrophizing, social participation and quality of life outcomes (pain intensity, pain disability, negative affectivity) in patients with low back pain in a multidisciplinary pain treatment.

Methods

Patients undergoing inpatient rehabilitation were surveyed at the beginning and two weeks after the end of rehabilitation. N = 262 low back pain patients participated (mean age: 52.2, 62.1 % female). A two-wave cross-lagged design and structural equation modeling were used to analyze data.

Results

We found evidence of reciprocal relations with regard to several outcomes. For example, pain catastrophizing at the beginning of treatment is associated with negative affectivity after rehabilitation, and the post-treatment value of pain catastrophizing is associated with pain disability and satisfaction with participation at the start of treatment. Pain disability and pain catastrophizing are predictors of lower treatment outcome while pain intensity and negative affectivity are not risk factors. Participation stands in a reciprocal relationship with some of the pain treatment outcomes. The surprising result, namely, that those patients more satisfied with social participation experience less improvement regarding catastrophizing, can be explained by ceiling effects and the Communal Coping Model.

Conclusions

This study provides evidence of the importance of taking reciprocal relations among pain catastrophizing, social participation and other pain outcomes into account. Providers of multidisciplinary pain treatment need to play attention to patients at risk with high disability and catastrophizing thoughts. Pain treatment would benefit from closer integration of psychosocial measures to foster social participation.

Using an internet intervention to support self-management of low back pain in primary care: protocol for a randomised controlled feasibility trial (SupportBack)

INTRODUCTION

Low back pain (LBP) is a prevalent and costly condition. The majority of patients experiencing LBP are managed in primary care, where first-line care recommendations consist of advice to self-manage and remain active. Internet interventions present a potential means of providing patients with tailored self-management advice and evidence-based support for increasing physical activity.

METHODS/ANALYSIS

This protocol describes a single-blind, randomised controlled feasibility trial of an internet intervention developed to support the self-management of LBP in primary care. Patients are being randomised to 1 of 3 groups receiving either usual primary care, usual primary care with the addition of an internet intervention or an internet intervention with physiotherapist telephone support. Patients are followed up at 3 months. Primary outcomes are the feasibility of (1) the trial design/methods, (2) the delivery of the internet intervention and (3) the provision of telephone support by physiotherapists. Secondary outcomes will include exploratory analysis of estimates and variation in clinical outcomes of pain and disability, in order to inform a future main trial.

ETHICS/DISSEMINATION

This feasibility trial has undergone ethical scrutiny and been approved by the National Health Service (NHS) Research Ethics Committee, REC Reference 13/SC/0202. The feasibility findings will be disseminated to the research community through presentations at conferences and publication in peer review journals. Broader dissemination will come following a definitive trial.

Should General Practitioners Issue a Sick Certificate to Employees Who Consult for Low Back Pain in Primary Care?

PURPOSE

Back pain is a common problem and has significant societal impact. Sickness certification is commonly issued to patients consulting their general practitioner with low back pain. The aim of this study was to investigate the association of certification for low back pain with clinical outcomes and cost consequences.

METHODS

A prospective cohort study using linked questionnaire and medical record data from 806 low back pain patients in 8 UK general practices: comparison of 116 (14.4%) who received a sickness certificate versus 690 who did not receive certification. The primary clinical measure was the Roland and Morris Disability Questionnaire (RMDQ). Data on back pain consultation and work absenteeism were used to calculate healthcare and societal costs.

RESULTS

Participants issued a sickness certificate had higher back-related disability at baseline consultation and 6-month follow-up [mean difference 3.1 (95% CI 1.8, 4.4) on the RMDQ], indicating worse health status. After fully adjusting for baseline differences, most changes in clinical outcomes at 6 months were not significantly different between study groups. Productivity losses were significantly higher for the certification group, with most absence occurring after the expected end of certification; mean difference in costs due to absenteeism over 6 months was £1,956 (95% CI £941, £3040).

CONCLUSIONS

There was no clear evidence of a difference in clinical outcomes between individuals issued a sickness certificate and those not issued a certification for their back pain. With little overall contrast in clinical outcomes, policy makers and care providers may wish to draw on the likely difference in societal costs alongside issues in ethical and moral care in their consideration of patient care for low back pain.

The Effectiveness of Cognitive Behavioural Treatment for Non-Specific Low Back Pain: A Systematic Review and Meta-Analysis

Objectives

To assess whether cognitive behavioural (CB) approaches improve disability, pain, quality of life and/or work disability for patients with low back pain (LBP) of any duration and of any age.

Methods

Nine databases were searched for randomised controlled trials (RCTs) from inception to November 2014. Two independent reviewers rated trial quality and extracted trial data. Standardised mean differences (SMD) and 95% confidence intervals were calculated for individual trials. Pooled effect sizes were calculated using a random-effects model for two contrasts: CB versus no treatment (including wait-list and usual care (WL/UC)), and CB versus other guideline-based active treatment (GAT).

Results

The review included 23 studies with a total of 3359 participants. Of these, the majority studied patients with persistent LBP (>6 weeks; n=20). At long term follow-up, the pooled SMD for the WL/UC comparison was -0.19 (-0.38, 0.01) for disability, and -0.23 (-0.43, -0.04) for pain, in favour of CB. For the GAT comparison, at long term the pooled SMD was -0.83 (-1.46, -0.19) for disability and -0.48 (-0.93, -0.04) for pain, in favour of CB. While trials varied considerably in methodological quality, and in intervention factors such as provider, mode of delivery, dose, duration, and pragmatism, there were several examples of lower intensity, low cost interventions that were effective.

Conclusion

CB interventions yield long-term improvements in pain, disability and quality of life in comparison to no treatment and other guideline-based active treatments for patients with LBP of any duration and of any age.

What is the perceived impact of Alexander technique lessons on health status, costs and pain management in the real life setting of an English hospital? The results of a mixed methods evaluation of an Alexander technique service for those with chronic back pain

Background

Randomised controlled trial evidence indicates that Alexander Technique is clinically and cost effective for chronic back pain. The aim of this mixed methods evaluation was to explore the role and perceived impact of Alexander Technique lessons in the naturalistic setting of an acute hospital Pain Management Clinic in England.

Methods

To capture changes in health status and resource use amongst service users, 43 service users were administered three widely used questionnaires (Brief Pain Inventory, MYMOP and Client Service Resource Inventory) at three time points: baseline, six weeks and three months after baseline. We also carried out 27 telephone interviews with service users and seven face-to-face interviews with pain clinic staff and Alexander Technique teachers. Quantitative data were analysed using descriptive statistics and qualitative data were analysed thematically.

Results

Those taking Alexander Technique lessons reported small improvements in health outcomes, and condition-related costs fell. However, due to the non-randomised, uncontrolled nature of the study design, changes cannot be attributed to the Alexander Technique lessons. Service users stated that their relationship to pain and pain management had changed, especially those who were more committed to practising the techniques regularly. These changes may explain the reported reduction in pain-related service use and the corresponding lower associated costs.

Conclusions

Alexander Technique lessons may be used as another approach to pain management. The findings suggests that Alexander Technique lessons can help improve self-efficacy for those who are sufficiently motivated, which in turn may have an impact on service utilisation levels.

Illness and treatment perceptions of patients with chronic low back pain: characteristics and relation to individual, disease and interaction variables

The significance of various cognitive and psychosocial factors in the development, progression and persistence of chronic low back pain (CLBP) is well demonstrated. However, only a few studies have addressed CLBP patients' cognitive representations or beliefs about their disease and its treatment. The present study aimed to: (1) describe the illness and treatment beliefs of patients with CLBP, e.g., expected timeline, controllability or treatment related concerns; and (2) explore the relation of these illness and treatment beliefs to individual-, disease- and interaction-related variables. We conducted a cross-sectional survey with N = 201 patients at four inpatient rehabilitation centers. The characteristics of illness and treatment perceptions were analyzed using descriptive statistics. Multiple regression analysis was used to test the associations with disease-related, individual-related and interaction-related variables. The results demonstrated large inter-individual variability in the illness and treatment perceptions among patients with CLBP and pointed to several associations with disease-related variables, patients' personal characteristics and interaction experiences. The variables most strongly related to individuals' perceptions were those reflecting disease severity and individual disease experience. Further research is needed on CLBP patients' illness and treatment perceptions, and these personal disease experiences should be considered when designing new treatment approaches.

Attitudes and beliefs of Australian chiropractors' about managing back pain: a cross-sectional study

Background

Chiropractors are frequent providers of care for patients with lower back pain. Biopsychosocial approaches to managing patients are regarded as best practice and are gaining wider acceptance. Recent evidence suggests that practitioners’ attitudes and beliefs may also have an important effect on patients’ recovery from back pain. Past studies have pooled manual therapists from differing professions. Dissonant findings have been hypothesised as being a result of the chiropractic subpopulation within multi-practitioner participant pools who are hypothesised to focus on biomedical aspects of treatment and minimize biopsychosocial dimensions.

The aim of this study is to determine whether a study population of only chiropractors would demonstrate similar attitudes and beliefs to other manual therapists’ biopsychosocial or biomedical approach to the management of their patients.

Methods

A survey of chiropractors in Victoria Australia in September 2010 was undertaken utilising the Pain Attitude and Belief Scale (PABS.PT), a tool which has been developed to determine the orientation (biopsychosocial or biomedical approach) of practitioners to the management of people with low back pain. The survey also obtained demographic data from respondents to determine whether variables such as education, gender or practice related factors influenced their orientation.

Results

The overall response rate was 29% (n = 218). The majority of the sample was male (68%), with a mean age of 44 years. The 6 point Likert scale scores were 34.5 (6.3) for the biomedical factor scale and 31.4 (4.1) for the biopsychosocial scale. Internal consistency of the psychosocial subscale was poor. None of the demographic variables were found to influence the biomedical or psychosocial scales.

Conclusions

Chiropractors in the state of Victoria were found to have similar biomedical and psychosocial orientations in their attitudes and beliefs when compared to other manual therapists’ levels of previous studies from differing cultural and educational backgrounds. This study was unable to replicate any of the relationships from past studies with any of the demographic variables. The psychosocial scale internal consistency may be a significant factor in this non-finding. Future research should address the identification of more robust items of the biopsychosocial attitudes of Victorian chiropractors toward treating lower back pain.

Prognosis of ankle syndesmosis injury

PURPOSE

Ankle syndesmosis injury has been associated with persistent pain and prolonged recovery; however, no predictors of prolonged recovery have been identified. The aims of this study were to establish prognosis for ankle syndesmosis injury compared with a lateral ankle sprain and to explore factors associated with prolonged recovery.

METHODS

Participants (n = 63) age 21 ± 3.2 yr, with acute ankle ligament injuries (diagnosed through magnetic resonance imaging), were recruited from 10 sport clubs and sports medicine and physiotherapy clinics in two Australian cities. Follow-up was until full recovery and with preinjury activity level. Time to return to play was compared between injury types using Kaplan-Meier survival curves. Secondary analysis investigated putative factors that increased risk of prolonged recovery. For this analysis, participants unrecovered at 2 wk completed the following: Fear Avoidance Beliefs Questionnaire (FABQ); Star Excursion Balance Test, weight-bearing lunge, and vertical jump (VJ). These variables were correlated with time to recovery using bivariate Pearson's r correlation coefficient.

RESULTS

The median recovery time for conservatively treated ankle syndesmosis injury was 62 and 15 d for lateral sprain. The sport-specific subscale scores of the FABQ were significantly higher (P = 0.017) for the ankle syndesmosis group, whereas vertical jump height was lower for this group, (P = 0.052). No baseline variables were strong predictors (r ≥ 0.6) of recovery. Moderate correlations were found for VJ (r = -0.471, P = 0.004) and the sport-specific subscale of the FABQ (r = 0.463, P = 0.004).

CONCLUSIONS

Conservatively treated ankle syndesmosis injuries took four times longer to recover than lateral ankle sprain. Tests such as VJ and FABQ may identify individuals at risk of prolonged recovery and allow health professionals to determine realistic and appropriate time to recovery.

Current and future trends in psychology and chronic pain: time for a change?

Psychological approaches to chronic pain have produced significant success and are widely accepted. Yet it can be difficult for those outside the field to understand the many different variables, processes and methods that are a part of these approaches. This is partly because these approaches are characterized by a wide variety of models, each with its own primary focus and background assumptions, and these can change over time. It may be difficult to create greater consistency and integration between currently disparate psychological approaches, but there may be advantages to doing so. This integration could be helped by an appropriately designed and appropriately organizing theoretical model. It is suggested that what is called the psychological flexibility model could provide such a point of integration.

Catastrophizing-a prognostic factor for outcome in patients with low back pain: a systematic review

BACKGROUND CONTEXT

Psychological factors including catastrophizing thoughts are believed to influence the development of chronic low back pain (LBP).

PURPOSE

To assess the prognostic importance of catastrophizing as a coping strategy in patients with LBP.

STUDY DESIGN

This is a systematic review.

PATIENT SAMPLE

This study included patients with LBP.

OUTCOME MEASURES

Work-related outcomes and perceived measures including return to work, pain, and disability.

METHODS

In September 2012, the following databases were searched: BIOSIS, CINAHL, Cochrane Library, Embase, OTSeeker, PeDRO, PsycInfo, Medline, Scopus, and Web of Science. To ensure completeness of the search, a hand search and a search of bibliographies were conducted and all relevant references included. All observational studies investigating the prognostic value of catastrophizing in patients with LBP were eligible. Included were studies with 100 and more patients and follow-up of at least 3 months. Excluded were studies with poor methodological quality, short follow-up duration, and small sample size.

RESULTS

A total of 1,473 references were retrieved, and 706 references remained after the removal of duplicates. For 77 references, the full text was assessed and 19 publications based on 16 studies were included. Of four studies that investigated work-related outcomes, two found catastrophizing to be associated with work status. Most studies that investigated self-reported outcome measures (n=8, 66%) found catastrophizing to be associated with pain and disability at follow-up in acute, subacute, and chronic LBP patients. In most studies that applied cutoff values, patients identified as high catastrophizers experienced a worse outcome compared with low catastrophizers (n=5, 83%).

CONCLUSIONS

There is some evidence that catastrophizing as a coping strategy might lead to delayed recovery. The influence of catastrophizing in patients with LBP is not fully established and should be further investigated. Of particular importance is the establishment of cutoff levels for identifying patients at risk.

Assessment of presurgical psychological screening in patients undergoing spine surgery: use and clinical impact

STUDY DESIGN

Prospective survey.

OBJECTIVE

To determine the prevalence of use of presurgical psychological screening (PPS) among spine surgeons in the United States, identify factors associated with PPS use, evaluate surgeons' opinions of PPS, and investigate how PPS is applied in clinical practice.

SUMMARY OF BACKGROUND DATA

The United States Preventive Services Task Force recommends PPS for patients undergoing back surgery. The prevalence of PPS is unknown. Thus, it may be difficult to improve preoperative care for such patients with psychological conditions.

METHODS

An online survey invitation was emailed to 340 spine surgeons. Questions addressed surgeon characteristics (eg, number of years in practice), practice characteristics (eg, practice type), inclusion of integrated rehabilitation and psychological services, and use of PPS. The impact of psychological factors on rehabilitation and recovery was assessed using an 11-point Likert scale (0, no impact; 10, highest impact). We analyzed the 110 (32%) responses with a χ(2) test (significance, P<0.05).

RESULTS

PPS was used by 37% (41) to screen for depression (100%) or anxiety (85%). PPS use was highest among surgeons with more experience, higher annual volume, and no university affiliation. Among those screening for fear avoidance, use was highest among surgeons more recently entering the field. Surgeons reported a strong belief regarding the impact of psychological factors on pain relief, adherence to therapy, and return to work (mean impact rating, >7.0); however, impact on return for follow-up was only moderate (mean rating, 5.8).

CONCLUSIONS

A minority of surgeons reported using PPS. Surgeons were less likely to use PPS if they had completed residency or begun practice within 14 years, had fewer than 200 cases annually, or were university affiliated. This study highlights the need to advocate for the use of North American Spine Society guidelines regarding the use of PPS.

The Brazilian version of STarT Back Screening Tool - translation, cross-cultural adaptation and reliability

Background:

Psychosocial factors are not routinely identified in physical therapy assessments, although they can influence the prognosis of patients with low back pain. The "STarT Back Screening Tool" (SBST) questionnaire aids in screening such patients for poor prognosis in the primary care setting and classifies them as high, medium, or low risk based on physical and psychosocial factors.

Objectives:

This study sought to translate and cross-culturally adapt the SBST to the Brazilian Portuguese language and test the reliability of the Brazilian version.

Method:

The first stage of the study consisted of the translation, synthesis, and back-translation of the original version of the STSB, including revision by the Translation Group, pretest of the translated version, and assessment by an expert panel. The pre-final Brazilian version was applied to 2 samples comprising 52 patients with low back pain; these patients were of both genders and older than 18 years of age. To assess the instrument's reliability, an additional sample comprising 50 patients was subjected to 2 interviews, and the results were assessed using the quadratic weighted kappa value. The instrument's internal consistency was assessed using Cronbach's alpha (n=105), and the standard error of measurement was also calculated (n=50).

Results:

Translation and back-translation attained consensus, and only item 6 required changes; the reformulated version was applied to an additional sample comprising 52 individuals who did not report any doubts related to this item. The reliability of the SBST-Brazil was 0.79 (95% confidence interval: 0.63-0.95), the internal consistency was 0.74 for the total score and 0.72 for the psychosocial subscale, and the standard error of measurement was 1.9%.

Conclusion:

The translated and cross-culturally adapted SBST-Brazil proved to be reliable for screening patients according to their risk of poor prognosis and the presence of psychosocial factors.

Health coaching for low back pain: a systematic review of the literature

OBJECTIVE

To systematically review the evidence for health coaching for patients with low back pain and describe the diversity of health coach training and interventions.

METHODS

Electronic databases Medline, CINAHL, EMBASE, PsycINFO, AMED and the Cochrane Central Register of Controlled Trials were searched to 24 June 2013 using individually devised strategies. Randomised or quasi randomised controlled trials (RCTs) of health coaching for adults with low back pain of any duration were considered. The overall quality of the body of evidence was assessed using the GRADE approach. Treatment effects were presented as the difference in mean scores with 95% confidence intervals and standardised mean difference at follow-up between health coaching and control groups. Health coaching interventions were compared narratively by their theoretical principles and the training and assessment of heath coaches.

RESULTS

Five publications describing three RCTs and one cluster RCT met the criteria for review. A rating of very low was assigned to the body of evidence using the GRADE approach. One RCT found significant improvements in lifting capacity and exercise compliance in favour of the health coaching group at both follow-up points with a large and moderate standardised mean difference. All included studies based health coaching interventions on the transtheoretical model of change however, the content of counselling programmes varied between studies and measures of treatment fidelity were inconclusive.

DISCUSSION

Variability in health coaching interventions and a lack of assessment of treatment fidelity in addition to the very low rating of the overall body of evidence identified in the current review renders any estimates of the effect of health coaching on low back pain uncertain. Well-designed RCTs of patients with sub-acute low back pain are required that incorporate clearly described protocols for health coaching interventions and include standardised measures of treatment fidelity.

Pain intensity, disability and depression in individuals with chronic back pain

OBJECTIVES

to measure the pain intensity, identify the disability and depression levels in people with chronic back pain and to correlate these variables. A cross-sectional, descriptive and exploratory study was undertaken at the Pain Treatment Clinic of the University of São Paulo at Ribeirão Preto Hospital das Clínicas, between February and June 2012, after receiving approval from the Ethics Committee at the University of São Paulo at Ribeirão Preto College of Nursing.

METHOD

sixty subjects with chronic back pain participated. The instruments used were: the 11-point Numerical Category Scale, the Roland-Morris Disability Questionnaire and the Beck Depression Inventory. To analyze the data, the arithmetic means, standard deviations and Spearman's correlation coefficient were calculated.

RESULTS

the findings show that the participants presented high pain, disability and depression levels. The correlation between pain intensity and disability and between pain intensity and depression was positive and weak and, between disability and depression, positive and moderate.

CONCLUSION

the study variables showed moderate and weak indices and the mutual correlations were positive.
