Psychometric properties of the Oswestry Disability Index

The aim of this study was to investigate the psychometric properties of the Oswestry Disability Index (ODI) in a large cross-sectional cohort of individuals with chronic low back pain by defining its internal consistency, construct structure and validity, and its ability to differentiate between different degrees of functional limitation. A total of 837 consecutive outpatient patients with low back pain were studied. The internal consistency of ODI was assessed by Cronbach's α, construct structure by exploratory factor analysis, construct validity by confirmatory factor analysis, and discrimination was determined by item response theory analysis. The ODI showed good internal consistency (α=0.85). Explanatory factor analysis showed that ODI is a unidimensional test measuring functional level and nothing else. The confirmatory factor analysis showed that the standardized regression weights of all ODI items were relatively high, varying from 0.5 to 0.7. The item response theory analysis suggested that eight out of 10 ODI items have a close to perfect ability to measure functional limitations in accordance with the actual severity of disability experienced by the respondents. Discrimination of all the items was high to perfect (1.08–2.01). The test characteristic and test information curves showed that the discriminative ability of the ODI is superior at higher levels of disability. The present data showed that the ODI is an internally consistent, unidimensional...

Authors: Bae CR, Jin Y, Yoon BC, Kim NH, Park KW, Lee SH Abstract BACKGROUND: Traditional sit-up exercise is a simple method to strengthen core muscles. However, it can increase the potential of lumbar spine injury during the bending process. OBJECTIVE: To evaluate the effect of assisted sit-up exercise (SUE) using a new training device, HubEX-LEX, on strengthening core muscles and improving non-specific low back pain (NSLBP) compared to conventional core stabilization exercise (CSE). METHODS: Subjects with chronic NSLBP were randomly divided into two groups: SUE (n= 18) or CSE (n= 18). They participated in...

Authors: Wewege M, Booth J, Parmenter B Abstract BACKGROUND/OBJECTIVE: This meta-analysis compared progressive aerobic training (PAT) to progressive resistance training (PRT) for pain, disability and quality of life (QoL) in people with chronic non-specific low back pain (CNSLBP). METHODS: Five electronic databases were systematically searched up to 1 March 2016. Randomised controlled trials included land-based PAT, PRT or combined PRT and PAT, versus usual care for CNSLBP. Exercise interventions were supervised a minimum of once per week and performed ⩾ 2 days/week for ⩾ 6 weeks. Outcome measurem...

This study will investigate whether the results of the first cognitive functional therapy randomised clinical trial are reproducible. The present study will have a sample size capable of detecting clinically relevant effects of the treatment with a low risk of bias. In pragmatic terms, this clinical trial is designed to reproduce the intervention as it would be performed in clinical practice by a trained physiotherapist who works with cognitive functional therapy, which increases the relevance of this study. The combined manual therapy and exercise group comprises an intervention strategy widely used by physiotherapists to...

Psychosocial risk factors may predispose to progression of back and neck pain to chronic pain or disability. Resilience (the ability to recover from stress) and pain self-efficacy (confidence that one can perform daily activities despite pain) are important psychometric properties shown to affect health and illness.

Authors: Noormohammadpour P, Kordi M, Mansournia MA, Akbari-Fakhrabadi M, Kordi R Abstract STUDY DESIGN: Single-blinded randomized controlled trial. PURPOSE: To evaluate the effects of a multi-step core stability exercise program in nurses with chronic low back pain (CLBP). OVERVIEW OF LITERATURE: CLBP is a common disorder among nurses. Considering that patient-handling activities predispose nurses to CLBP, core stability exercises suggested for managing CLBP in the general population may also be helpful in nurses. However, sufficient evidence is not available on whether a multi-step core stability exercise...

The objectives of this study were, first, the evaluation of the prevalence of BTP in patients with CLBP in the South of Spain (N = 1,868) and, second, the characterization of BTP in these patients (N = 295). Data was collected on presence of BTP, type and location of pain, treatment, compliance, and patient satisfaction. We found a prevalence of BTP in patients with CLBP of 37.5% (95% CI: 35.3%-39.7%), similar in men and women. 75% of the patients were older than 50 years. The preferred drug of patients who control BTP with opioids is fentanyl (78.3%) and its most common form of administration is nasal (53.2%). Therapeutic...

One of the fundamental distinctions we need to make when working with people who experience pain is to understand the difference between experiencing pain – and the behaviour or actions or responses we make to this experience. This is crucial because we can never know “what it is like” to experience pain – and all we have to rely on as external observers is what we see the person doing. Differentiating between the various dimensions associated with our experience of pain makes it far easier to address each part in the distinct ways needed. Let me explain. We know the current definition of pain &ndas...

We describe the mixed-methods (qualitative and quantitative) development and preliminary validation of the Patient Assessment for Low Back Pain–Symptoms (PAL-S), a patient-reported outcome measure for use in chronic low back pain (cLBP) clinical trials. Qualitative methods (concept elicitation and cognitive interviews) were used to identify and refine symptom concepts and quantitative methods (classical test theory and Rasch measurement theory) were used to evaluate item- and scale-level performance of the measure using an iterative approach. Patients with cLBP participated in concept elicitation interviews (N = 43),...

Conclusions: Although being more challenging to patients, Exposure is an effective treatment, which can be delivered in a psychological treatment setting and should be offered as a short-term treatment. (PsycINFO Database Record (c) 2018 APA, all rights reserved)
