The effects of a three-week use of lumbosacral orthoses on trunk muscle activity and on the muscular response to trunk perturbations.

Background: The effects of lumbosacral orthoses (LSOs) on neuromuscular control of the trunk are not known. There is a concern that wearing LSOs for a long period may adversely alter muscle control, making individuals more susceptible to injury if they discontinue wearing the LSOs. The purpose of this study was to document neuromuscular changes in healthy subjects during a 3-week period while they regularly wore a LSO.

Factors predicting and reducing mortality in patients with invasive Staphylococcus aureus disease in a developing country.

Background: Invasive Staphylococcus aureus infection is increasingly recognised as an important cause of serious sepsis across the developing world, with mortality rates higher than those in the developed world. The factors determining mortality in developing countries have not been identified.

Methods: A prospective, observational study of invasive S.

Staphylococcus aureus bacteraemia in a tropical setting: patient outcome and impact of antibiotic resistance.

Background: Most information on invasive Staphylococcus aureus infections comes from temperate countries. There are considerable knowledge gaps in epidemiology, treatment, drug resistance and outcome of invasive S. aureus infection in the tropics.

The effects of a 3-week use of lumbosacral orthoses on proprioception in the lumbar spine.

Study Design: Longitudinal, repeated-measures, factorial design. The trunk axial rotation repositioning error was the dependent variable, while the orthoses, test mode (passive versus active), and the testing session were the independent variables.

Objectives: To verify whether lumbosacral orthoses (LSOs) affect proprioception in the lumbar spine and whether these effects change over a 3-week period during which the LSO is consistently worn.
