Low back pain (LBP) is a chronic disorder which exerts a profound impact on various spheres of psychosocial functioning, including emotional distress, functional limitations and decrements in social contacts. The objective of this study was to investigate the associations between the indices of psychosocial functioning in patients with chronic LBP and a range of psychological factors. Specifically, the study aimed at exploring the relative participation of personality, social support, disease-related cognitive appraisals and coping styles in accounting for the differences in psychosocial functioning of patients with LBP. ⋯ Among sociodemographic variables, older age and lower educational level were related to greater subjective feelings of being disabled. Pain severity was found unrelated to any of psychosocial functioning domains. Different aspects of psychosocial functioning are best accounted for by diverse patterns of psychological factors, which suggests involvement of different psychological mechanisms in development of LBP-related disability.

The aim of this cross-sectional pilot-study was to investigate the relationship between psychological distress and free-living physical activity (PA) in individuals with chronic low back pain (CLBP). Thirty-eight participants with non-specific CLBP (29=distressed; 9=non-distressed) were recruited. PA levels were measured using an accelerometer (activPAL activity monitor) over a one week period. ⋯ Depressive symptoms were a statistically significant independent predictor of time upright (beta=-0.49, p<0.05). This pilot-study found that individuals with CLBP and elevated levels of distress spend less time upright than their non-distressed counterparts. Clinically, when treating individuals with CLBP and elevated distress levels, free-living PA may be low and interventions aimed at increasing upright activity may be appropriate.

A cross-sectional population-based study. ⋯ This large population-based study indicates that obesity is associated with a high prevalence of low back pain. Further studies are needed to determine if the association is causal.

Spinal stabilisation exercises are commonly used in the management of low back pain (LBP). There is limited evidence relating to patients' experiences of their involvement in such programmes. The aim of this study was to explore the experiences of a sample of individuals with chronic LBP who participated in a randomised controlled trial (RCT) investigating the most efficacious dosage and frequency of spinal stabilisation exercises. ⋯ Four themes emerged: Physical dimensions of the LBP experience, emotional and psychological dimensions of the LBP experience and perceived effects of the programme and lastly, the impact of the treatment programme on participants' knowledge, understanding and adherence. In conclusion participants' experiences were not limited to the positive effects of stabilisation exercises on pain, functional disability and quality of life, but also reflected increases in confidence, the formulation of self help strategies and the ability to exert better control over their LBP. The findings highlight the importance of well planned associated educational support packages in the treatment of LBP paving the way for future qualitative research.

Understanding prognosis is important in managing low back pain. In this article, we discuss the available evidence on low back pain prognosis and describe how prognostic evidence can be used to inform clinical decision making. We describe three main types of related prognosis questions: 'What is the most likely course?' (Course studies); 'What factors are associated with, or determine, outcome?' (Prognostic factor or explanatory studies); and 'Can we identify risk groups who are likely to have different outcomes?' (Risk group or outcome prediction studies). ⋯ Important low back pain prognostic factors are related to the back pain episode, the individual and psychological characteristics, as well as the work and social environment. Although numerous studies have developed prediction models in the field, most models/tools explain less than 50% of outcome variability and few have been tested in independent samples. We discuss limitations and future directions for research in the area of low back pain prognosis.
