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)
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)
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)
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)
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)
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)
INTRODUCTION Recent guidelines pertaining to exercise for individuals with osteoarthritis have been released. These guidelines have been based primarily on studies of knee-joint osteoarthritis. The current study was focused on the hip joint, which has different biomechanical features and risk factors for osteoarthritis and has received much less attention(More)
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)
AbstrAct Lumbar posture is considered to play an important role in low back injury and is of importance during the rehabilitation of clients employed in manual handling occupations. This clinical commentary discusses the implications of lumbar posture on the biomechanical loads placed on the active and passive tissues of the spine, and the contribution the(More)
Decreases in stature (shrinkage) are used to indicate exercise induced spinal loading. This study examined the effect of three running speeds on two groups of runners, one with chronic low back pain. The two groups of seven male marathon runners ran at 70%, 85%, and 100% of their marathon race pace for 30 min on separate occasions. Before and after exercise(More)
