Considered from medical, social or economic perspectives, the cost of musculoskeletal injuries experienced in the workplace is substantial, and there is a need to identify the most efficacious interventions for their effective prevention, management and rehabilitation. Previous reviews have highlighted the limited number of studies that focus on upper(More)
The objective of the present study was to determine whether differences in the frictional properties of a floor surface may affect the kinematics and kinetics of pushing and pulling. Eight male participants were required to push and pull a four-wheeled trolley over two level surfaces, on which were mounted floor coverings with good (safety floor) and(More)
OBJECTIVE To investigate the short-term effects of recreational running on the deformation of knee articular cartilage and to examine the relationship between changes in knee cartilage volume and biomechanical modulators of knee joint load. METHOD Twenty healthy volunteers participated in a two phase cross-sectional study. Session 1 involved Magnetic(More)
Bedside safety rails are used extensively throughout hospitals and residential care environments as a safety device to protect people against the risk of falling out of bed. However, several adverse incidents involving body entrapment have been linked to their use, which have resulted in serious injury to the bed occupants and, in more extreme cases,(More)
BACKGROUND Twelve percent of work-related low back injuries have been attributed to sudden loading events. When a sudden load is applied to an object that is held in front of the body, postural responses are rapid, yet it is not clear whether these responses differ with respect to initial posture at the time of loading, or by providing prior exposure to, or(More)
OBJECTIVE A frequently cited problem in epidemiological research is the inadequate operational definition of umbrella terms such as Musculoskeletal Disorders (MSD). Specific conditions attached to these labels and their corresponding signs and symptoms are also poorly defined. The purpose of this study was to identify internationally applied terminology and(More)
PURPOSE There is substantial evidence indicating an increase in the incidence of lower limb joint osteoarthritis with increasing age. One factor that may contribute to this is an age related reduction in the ability to attenuate the impulse generated during gait and step descent. SCOPE The aim of this study was to investigate the differences between older(More)
Physiological, perceptual and physical responses to a typical circuit weight-training (CWT) regimen were recorded in two studies. The aims were to assess the intensity of exercise during CWT; and to determine whether physical responses as evaluated by spinal shrinkage were related to physiological and perceptual responses to CWT. In the first study (n = 10)(More)
Spinal shrinkage, measured by changes in stature, is used as an index of spinal loading as alterations reflect changes in intervertebral disc height. Shrinkage induced by various physical activities may be reversed using gravity inversion. The present purpose was to examine the shrinkage induced by a drop jumping regimen and evaluate gravity inversion(More)
