Do people with recurrent back pain constrain spinal motion during seated horizontal and downward reaching?

Background: Although the effect of symptomatic back pain on functional movement has been investigated, changes to spinal movement patterns in essentially pain-free people with a history of recurrent back pain are largely unreported. Reaching activities, important for everyday and occupational function, often present problems to such people, but have not been considered in this population. The purpose of this study was to compare the amplitude and timing of spinal and hip motions during two, seated reaching activities in people with and without a history of recurrent low back pain (RLBP).Methods: Spinal and hip motions during reaching downward and across the body, in both directions, were tracked using electromagnetic sensors. Analyses were conducted to explore the amplitudes, velocities and timings of 3D segmental movements and to compare controls with subjects with recurrent, but asymptomatic lumbar or lumbosacral pain.Findings: We detected significant differences in the amplitude and timing of movement in the lower thoracic region, with the RLBP group restricting movement and demonstrating compensatory increased motion at the hip. The lumbar region displayed no significant between-group differences. The order in which the spinal segments achieved peak velocity in cross-reaching was reversed in RLBP compared to controls, with lumbar motion leading in controls and lagging in RLBP.Interpretation: Subjects with a history of RLBP show a number of altered kinematic features during reaching activities which are not related to the presence or intensity of pain, but which suggest adaptive changes to movement control.

A discursivização em Wall.E: sociedade, tecnologia e poder

This article consists in a discourse analysis of the feature film in animation Wall.e produced by Pixar in association to Disney in 2008. Pixar has been known to produce films that contain various discursive levels, making its products appealing not only for children, but also for adults. However, Wall-e proves to be a masterpiece in Pixar carrier, because it is the one which focuses on the analysis and critique of contemporary society associated with technological development. For this, the plot has as its starting point the question of sustainability and unbridled consumerism. But the film expands the debate, tracing the relationship between technology and humanity, discussing how one affects the other. The project therefore aims to show how the animation works such concepts and constructs his discourse. To this end, the work seeks to identify the signs that make up the discourse and draw the intertextuality between WALL.E and other works that also discuss the same elements such as Stanley Kubrick‟s 2001 - A Space Odyssey (1968)

O cinema sem rua

The project consists of a book-report on the street movie theaters in Brazil, which are increasingly scarce. Multiplexes are taking the market by several factors, including scheduling and directed to the blockbusters that malls provide security, which does not occur in street theaters, which have a more independent programming. The report will portray the film as a physical space and playful all the influence that the place provides, yet is losing its audience
