Fear avoidance and prognosis in back pain: a systematic review and synthesis of current evidence

Abstract: Purpose and Background: Despite widespread clinical belief, a previous systematic review found insufficient evidence to substantiate fear avoidance beliefs (FAB) as a risk factor for long-term problems in low back pain. This updated review explores whether there is stronger evidence supporting the role of fear avoidance in early stages of low back pain as a predictor of outcome. In addition, this evidence was examined in reference to current models and knowledge about fear avoidance.Methods and Results: A systematic literature search for all prospective inception cohorts of low back pain that included psychological factors at baseline between 2000 and 2003 was made. We searched MEDLINE, psychINFO, AMED, CINAHL, Social Science Citation Index, Science Citation Index databases. Included studies had early recruitment of up to three weeks since onset of back pain and an absence of back pain in the previous three months. These studies were coded according to criteria adapted from Pincus et al (2002) blindly by ...

Perceived diagnostic uncertainty in pediatric chronic pain.

Abstract: In this review, we argue that perceived diagnostic uncertainty in idiopathic pediatric chronic pain patients and their parents is critically important for understanding pain cognitions, behavioral responses to pain, treatment choices, and outcomes during this developmental period. We include evidence from children (under 12 years) and adolescents (12-18 years). This period sets the stage for future experience of pain: two thirds of children and adolescents with chronic pain will become adults with chronic pain [30]. The prevalence of pediatric chronic pain is rising, and has been described as a growing epidemic [11]. Better understanding of this core issue through well-designed research with pediatric populations is therefore crucial.

Is an enhanced behaviour change intervention cost-effective compared with physiotherapy for patients with chronic low back pain? Results from a multicentre trial in Israel

Abstract: Objective To assess the cost-effectiveness of an enhanced transtheoretical model of behaviour change in conjunction with physiotherapy compared with standard care (physiotherapy) in patients with chronic lower back pain (CLBP). Design Cost-utility and cost-effectiveness analyses alongside a multicentre controlled trial from a healthcare perspective with a 1-year time horizon. Setting The trial was conducted in eight centres within the Sharon district in Israel. Participants 220 participants aged between 25 and 55 years who suffered from CLBP for a minimum of 3 months were recruited. Interventions The intervention used a model of behaviour change that sought to increase the adherence and implementation of physical activity in conjunction with physiotherapy. The control arm received standard care in the form of physiotherapy. Primary and secondary measures The primary outcome was the incremental cost per quality-adjusted life year (QALY) of the intervention arm compared with standard care. The secondary outcome was the incremental cost per Roland-Morris Disability Questionnaire point. Results The cost per QALY point estimate was 10 645 New Israeli shekels (NIS) (£1737.11). There was an 88% chance the intervention was cost-effective at NIS50 000 per QALY threshold. Excluding training costs, the intervention dominated the control arm, resulting in fewer physiotherapy and physician visits while improving outcomes. Conclusions The enhanced transtheoretical model intervention appears to be a very cost-effective intervention leading to improved outcomes for low cost. Given limitations within this study, there is justification for examining the intervention within a larger, long-term randomised controlled trial. Trial registration number NCT01631344; Pre-results.

Outcomes in Distressed Patients With Chronic Low Back Pain: Subgroup Analysis of a Clinical Trial.

Abstract: Study Design Subgroup analysis of a controlled clinical trial. Background Current evidence suggests that people with chronic low back pain who are distressed may require different interventions than do those who are not distressed. Recently, the enhanced transtheoretical model intervention (ETMI) reported significant improvements in disability and pain and increased physical activity in patients with chronic low back pain compared to physical therapy as usual. Objectives To compare outcomes between ETMI and physical therapy interventions for participants with and without self-reported distress. Methods We tested the interaction between intervention (ETMI versus physical therapy) and distress status (using the Medical Outcomes Study 12-Item Short-Form Health Survey cut point), and performed between-group comparisons on 3 separate outcomes (disability, pain, and physical activity) at 3 and 12 months. Results In the ETMI group, 57 of 108 participants were considered distressed, versus 62 of 106 participants in the physical therapy group. The interaction between intervention and distress at 12 months was significant. Participants improved with both interventions, but the magnitude of change in distressed participants who received ETMI was larger than that in distressed participants who received physical therapy (mean ± SD difference from baseline in disability of 6.1 ± 6.1 in the ETMI group, compared with 3.4 ± 6.7 in the physical therapy group). Conclusion The enhanced transtheoretical model intervention was significantly more effective than physical therapy in participants with distress. The trial was registered in ClinicalTrials.gov (NCT01631344). Level of Evidence Therapy, level 2b. J Orthop Sports Phys Ther 2018;48(6):491-495. Epub 27 Mar 2018. doi:10.2519/jospt.2018.7670.

The feasibility and acceptability of a physical activity intervention for older people with chronic musculoskeletal pain: The iPOPP pilot trial protocol.

Abstract: Introduction: This pilot trial will inform the design and methods of a future full-scale randomized controlled trial (RCT) and examine the feasibility, acceptability and fidelity of the Increasing Physical activity in Older People with chronic Pain (iPOPP) intervention, a healthcare assistant (HCA)-supported intervention to promote walking in older adults with chronic musculoskeletal pain in a primary care setting. Methods and analysis: The iPOPP study is an individually randomized, multicentre, three-parallel-arm pilot RCT. A total of 150 participants aged ≥65 years with chronic pain in one or more index sites will be recruited and randomized using random permuted blocks, stratified by general practice, to: (i) usual care plus written information; (ii) pedometer plus usual care and written information; or (iii) the iPOPP intervention. A theoretically informed mixed-methods approach will be employed using semi-structured interviews, audio recordings of the HCA consultations, self-reported questionnaires, case report forms and objective physical activity data collection (accelerometry). Follow-up will be conducted 12 weeks post-randomization. Collection of the quantitative data and statistical analysis will be performed blinded to treatment allocation, and analysis will be exploratory to inform the design and methods of a future RCT. Analysis of the HCA consultation recordings will focus on the use of a checklist to determine the fidelity of the iPOPP intervention delivery, and the interview data will be analysed using a constant comparison approach in order to generate conceptual themes focused around the acceptability and feasibility of the trial, and then mapped to the Theoretical Domains Framework to understand barriers and facilitators to behaviour change. A triangulation protocol will be used to integrate quantitative and qualitative data and findings.
