It is unknown how structural (sex, stature, body mass) and functional (strength, flexibility)
personal factors influence lifting strategy in paramedic work. We explored whether variance …

Background Biomechanical models have been developed to predict spinal loads in vivo to
assess potential risk of injury in workplaces. Most models represent trunk muscles with …

Different lifting analysis tools are commonly used to assess spinal loads and risk of injury.
Distinct musculoskeletal models with various degrees of accuracy are employed in these …

A study was performed to investigate how different types of handle coupling affect the
loading on the spine. Ten male grocery item selectors performed a laboratory simulation of a …

The purpose of this study was to investigate the effectiveness and user acceptability of a
Personal Lift-Assist Device (PLAD) at an automotive manufacturing facility, with operators …

Manual lifting techniques are commonly defined in terms of the postures adopted at the start
of the lift. Quantitative definition is problematic, however, because the absolute joint angles …

Objective Spine kinematics, kinetics, and trunk muscle activities were evaluated during
different stages of a fatigue-induced symmetric lifting task over time. Background Due to …

Exposure to cognitive distractions and precision placement challenges during manual lifting
exertions may alter lumbar spine loading by influencing movement and/or motor patterns. In …

Wearable devices are becoming ubiquitous and can be used to better estimate postures and
movements to reduce the risk of injuries. Thirty-three participants were recruited in this study …

Regular carriage of heavy loads such as backpacks, satchels and mailbags results in a
variety of acute medical problems and increased potential for back injury. There is a paucity …
