Clinical Trial
Movements of the pelvis and lumbar spine during walking in people with acute low back pain.
Little is known about how acute low back pain affects pelvic and lumbar movements during walking. The aim of the present study was to determine if measurement of the amplitude of the angular movements of the pelvis and lumbar spine during walking is useful in the evaluation of people with acute low back pain. ⋯ Measurement of pelvic and lumbar movements during walking is unlikely to have useful clinical applications for individuals, or when discriminating between impaired and unimpaired people, but may be applied to groups for hypothesis testing in evaluating change in back pain over time. An hypothesized model to explain the observed movements has been proposed.

Comparative Study
Attitudes and beliefs of Brazilian and Australian physiotherapy students towards chronic back pain: a cross-cultural comparison.
The attitudes and beliefs of physiotherapists and students can potentially influence the outcome of treatment of low back pain. These attitudes and beliefs may be influenced by external factors, such as ethnicity. No study that compared the attitudes and beliefs of physiotherapy students from different cultural backgrounds, such as from Brazil or Australia, towards chronic low back pain was found. The purpose of the present study was therefore to compare the attitudes and beliefs of Brazilian physiotherapy students with those of Australian physiotherapy students and to published data from North American healthcare providers, and to investigate whether a history of chronic low back pain affects students' attitudes and beliefs. ⋯ As demonstrated by higher HC-PAIR scores, the Brazilian physiotherapy students agree more strongly with the notion that low back pain justifies disability and activity limitation than do Australian physiotherapy students and North American healthcare providers. A history of chronic low back pain does not affect students' attitudes and beliefs.

This cross-sectional study was designed to determine the prevalence and risk factors for low back pain in an urban community. A house-to-house enquiry was conducted using a questionnaire administered by trained interviewers. Four hundred and seventy-four respondents, 271 men (57%) and 203 women (43%) participated in the study. ⋯ The prevalence of back pain was highest among farmers (85%) and lowest among housewives (32%). The prevalence of low back pain in this community is comparable to levels recorded in industrialized countries. However, in this study low back pain did not feature as a main cause of morbidity, accounting for a mean of 3 days off work per person per year.

Psychosocial factors predictive of occupational low back disability: towards development of a return-to-work model.
This paper focuses on the identification and testing of potential psychosocial factors contributing to an integrated multivariate predictive model of occupational low back disability. Psychosocial predictors originate from five traditions of psychosocial research: psychopathological, cognitive, diathesis-stress, human adaptation and organizational psychology. The psychosocial variables chosen for this study reflect a full range of research findings. ⋯ The key psychosocial predictors identified were expectations of recovery and perception of health change. Also implicated, but to a lesser degree, were occupational stability, skill discretion at work, co-worker support, and the response of the workers' compensation system and employer to the disability. All psychosocial models were better at predicting who will return than who will not return to work.
