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: Yang LH, Duan PB, Hou QM, Du SZ, Sun JF, Mei SJ, Wang XQ Abstract OBJECTIVES: To identify the efficacy of auricular acupressure on pain and disability for chronic LBP by systematic review. METHODS: A search of randomized controlled trials was conducted in four English medical electronic databases and three Chinese databases. Two reviewers independently retrieved related studies, assessed the methodological quality, and extracted data with a standardized data form. Meta-analyses were performed using all time-points meta-analysis. RESULTS: A total of 7 trials met the inclusion criteria, of which 4 ha...

In the modern society the low back pain (LBP) is the most common cause of temporary disability with estimated life time prevalence as high as 23 –80% (Pedisic et al., 2013). LBP with radiculopathy is considered as the most unfavorable prognostic risk factor for the development of chronic pain syndrome and low quality of life (Konstantinou et al., 2013). The aim of this study is to evaluate the short-term efficacy of repetitive peripheral m agnetic stimulation (rPMS) in the treatment of lumbosacral radiculopathy.

Knee osteoarthritis is, like so many chronic pain problems, a bit of a weird one. While most of us learned that osteoarthritis is a fairly benign disease, one that we can’t do a whole lot about but one that plagues many of us, the disability associated with a painful knee is pretty high – and we still don’t have much of a clue about how the pain we experience is actually generated.  Cartilage doesn’t have nociceptive fibres, yet deterioration of cartilage is the hallmark of osteoarthritis, though there are other structures capable of producing nociceptive input around the knee joint. Perhaps, a...

CONCLUSIONS: Due to the low- to very low-quality of the evidence for all treatment comparisons, outcomes, and follow-up periods investigated, it is uncertain if Back School is effective for chronic low back pain. Although the quality of the evidence was mostly very low, the results showed no difference or a trivial effect in favour of Back School. There are myriad potential variants on the Back School approach regarding the employment of different exercises and educational methods. While current evidence does not warrant their use, future variants on Back School may have different effects and will need to be studied in fut...

Conclusions: Allogeneic MSC therapy may be a valid alternative for the treatment of degenerative disc disease that is more logistically convenient than the autologous MSC treatment. The intervention is simple, does not require surgery, provides pain relief, and significantly improves disc quality.

Have you ever wondered why there are so many treatments for low back pain? Like there are actually hundreds of different ways to “treat” back pain… yet the truth is, none of them work for everyone. Actually, most of them seem to help pass the time until low back pain settles of its own accord. Until it’s back again (no pun intended!). This post is prompted after reading a string of general news articles discussing the common non-specific low back pain – under various guises of “dead butt syndrome“, “Dr Tom: Ouch I’ve hurt my back” and the like – I think it&...

Chronic non-specific low back pain (CNLBP) is a prevalent problem among athletes that can cause long-lasting disability and time lost from sporting activities. Thus far, a variety of methods have been suggested to address this problem, including spinal manipulation (SM) and Kinesio Tape ® (KT). The aim of this study was to investigate whether adding KT to SM can provide any extra effect in athletes with CNLBP or not.
