A prospective cohort study. ⋯ The significant association between medium level back extension endurance and increased LBP intensity supports the finding of other studies that particularly back extension endurance is an important physical fitness component in preventing LBP and that the subcomponents of physical fitness are related in different ways to LBP.

Low back pain is common among Brazilians, especially affecting those who are working. Psychosocial factors, such as the health locus of control, are associated with low back pain prognoses. Although the multidimensional health locus of control questionnaire is widely employed in individuals with low back pain, a Brazilian-Portuguese version is not yet available. The aim of the present study was to translate and adapt the multidimensional health locus of control (MHLC) questionnaire, and to investigate its psychometric properties in a Brazilian population with non-specific chronic low back pain. ⋯ The Brazilian-Portuguese version of the MHLC questionnaire has acceptable measurement properties similar to that observed with the original English language version.

Design of the experiment is to study the cross-sectional sample with retrospective information. The objective is to identify the types of physical activity associated with the decreased occurrence of low-back pain (LBP) in schoolchildren. Physical activity may be hypothesized to possess a potential for LBP prevention. ⋯ Among sports activities, only swimming and the number of hours per week participating in soccer were associated with a decreased LBP prevalence. With the exception of swimming and soccer, the types of sport reported by this schoolchild population do not offer themselves for consideration as tools for LBP prevention. Based on the associations found with indicators of physical inactivity, attempts to motivate the children to increase their general physical activity level should be considered for trial.

[The Brazilian version of the Fear Avoidance Beliefs Questionnaire].
The aim of the present study was to investigate the psychometric properties and validate the Portuguese version of the Fear Avoidance Beliefs Questionnaire (FABQ-Brazil). This instrument assesses how beliefs and fear of individuals with lower back pain affect two subscales related to their physical activities (FABQ-Phys) and work (FABQ-Work). The questionnaire was translated into Brazilian Portuguese, following the recommended methodology, and applied to 53 individuals with non-specific chronic lower back pain. ⋯ The stepwise multiple regression analyses revealed statistically significant correlations between all isolated items with their respective subscales, and the set of the items explained 99% of the changes in scores for each subscale. No significant correlations were found between the subscales; however, both the FABQ-Phys and FABQ-Work subscales were positively associated with pain intensity (visual numerical scale) and degree of disability (Roland Morris Questionnaire). These findings supported the evidence that the FABQ-Brazil showed adequate psychometric properties for individuals with chronic lower back pain.
