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...

As I read blogs and tweets and posts on social media, and even peer reviewed papers in journals, I often read that what we’re trying to do in sub-acute pain management is to prevent chronic pain from developing (note, when I talk about pain that goes on beyond healing, more than three months, or has no useful function, I may use the term “chronic” or I may use the more recent term “persistent” – they mean the same thing, except persistent has perhaps less baggage…). I want to take aim at that focus – to prevent pain from persisting – and think carefully about it. Let&r...

ConclusionTurkish version of the COMI has acceptable psychometric properties. It is a valid and reliable instrument and cross-culturally adapted, in accordance with established guidelines, for the use by Turkish-speaking patients. It can be recommended for use in evaluation of patients with chronic LBP in daily practice, in international multicenter studies and in spine registry systems.

Authors: Nijs J, Clark J, Malfliet A, Ickmans K, Voogt L, Don S, den Bandt H, Goubert D, Kregel J, Coppieters I, Dankaerts W Abstract Conservative, surgical and pharmacological strategies for chronic low back pain (CLBP) management offer at best modest effect sizes in reducing pain and related disability, indicating a need for improvement. Such improvement may be derived from applying contemporary pain neuroscience to the management of CLBP. Current interventions for people with CLBP are often based entirely on a "biomedical" or "psychological" model without consideration of information concerni...

I’ve been writing about psychosocial factors and pain but I realise that I haven’t actually defined what I mean by psychosocial factors. The strange thing about this term is that it’s often conflated with “psychological” or “psychopathological” when it’s actually not. So… where to begin? The Collins English Dictionary defines psychosocial as: “of or relating to processes or factors that are both social and psychological in origin”, while the Oxford English Dictionary defines it as “Of or relating to the interrelation of social factors and individual t...

BACKGROUND CONTEXT: Patients with adult degenerative scoliosis (ADS) demonstrate an altered gait pattern. Age related changes such as progressive and asymmetric degeneration of the disc and facet joints are associated with degenerative adult scoliosis and lead to segmental instability, deformity and stenosis. Psychological clinical outcome questionnaires (FABQ and TSK) are a reliable and valid measure of the fear of movement related to chronic lower back pain. Self-report measures are routinely used in the clinical setting to capture data related to back and leg pain symptoms, function and perceived disability.

BACKGROUND CONTEXT: Chronic low back pain is a major source of disability in the United States and throughout the world. Traditional treatments such as conservative care, opioids, injection therapy, lumbar fusion and lumbar disc replacement have shown variable results. The INTRACEPT Intraosseous Nerve Ablation System is the first targeted therapy to relieve chronic low back pain in the presence of Modic type 1 or 2 abnormalities by denervating the nociceptive pain signaling within the vertebral body (VB).

Authors: Ulger O, Demirel A, Oz M, Tamer S Abstract BACKGROUND AND OBJECTIVES: To determine the effects of spinal stabilization exercises (SSE) and manual therapy methods on pain, function and quality of life (QoL) levels in individuals with chronic low back pain (CLBP). METHODS: A total of one-hundred thirteen patients diagnosed as CLBP were enrolled to the study. The patients allocated into Spinal Stabilization group (SG) and manual therapy group (MG), randomly. While SSE performed in SG, soft tissue mobilizations, muscle-energy techniques, joint mobilizations and manipulations were performed in MG. While the...
