As a simple solution to alleviate problems associated with manual material handling,
manual vehicles, such as carts, trucks, wheelbarrows, etc., are often provided to operators …

Objective. Humans have limited power and require mechanization, to meet high energy
demand, through equipment. We initiated this study to accumulate data from previous …

Hand–handle interface is seldom considered in contemporary upper limb biomechanical
analyses of pushing and pulling strength. A laboratory study was designed to examine if …

This study investigated arm posture and hand forces during bi-manual pushing. Nine male
and eight female participants performed isometric exertions at two reach distances (0 and …

Background Overloading is hypothesized to be one of the failure mechanisms following total
elbow arthroplasty (TEA). It is unclear whether the current post-operative loading instruction …

Touch pens allow user to write directly on a computer screen. An ergonomically designed
touch pen can improve user performance and reduce musculoskeletal injuries. This study …
