Background As the work load has been shifting from heavy manufacturing to office work,
neck disorders are increasing. However, most of the current cervical spine biomechanical …

The objective of this study was to investigate biomechanical loading to the low back as a
result of wearing an exoskeletal intervention designed to assist in occupational work. Twelve …

Background Computational spine models of various types have been employed to
understand spine function, assess the risk that different activities pose to the spine, and …

Industrial passive low-back exoskeletons have gained recent attention as ergonomic
interventions to manual handling tasks. This research utilized a two-armed experimental …

This study evaluated loading on the low back while wearing two commercially available
postural assist exoskeletons. Ten male subjects lifted a box from multiple lift origins …

The objective of this study was to evaluate three passive upper-extremity exoskeletons
relative to a control condition. Twelve subjects performed an hour-long, simulated …

Firefighters and EMS providers continue to be challenged when lifting heavy patients in their
homes. This study investigated the biomechanical efficacy of four devices that could be used …

This paper presents a novel fiber-based muscle model for the forward dynamics of the
musculoskeletal system. While bones are represented by rigid bodies, the muscles are …

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 …

Though biomechanically determined guidelines exist for lifting, existing recommendations
for pushing and pulling were developed using a psychophysical approach. The current …
