Over-exposure of the hand-arm system to intense vibration and force over time may cause degeneration of the vascular, neurological, and musculoskeletal systems in the fingers. A novel animal model using rat tails has been developed to understand the

Previous studies from our laboratory showed that prenatal exposure to hexavalent chromium, Cr(VI), caused premature ovarian failure and decreased pregnancy rates and litter size. Exposure to the endocrine disrupting chemicals (EDCs) can cause X-chrom

Awkward kneeling in sloped shingle installation operations exposes roofers to knee musculoskeletal disorder (MSD) risks. To address the varying levels of risk associated with different phases of shingle installation, this research investigated utiliz

The objective of this study was to develop a new rat-tail vibration model for studying finger vibration health effects. Unlike the previous rat-tail models, the vibration strain and stress of the rat tail can be conveniently and reliably quantified a

The hand coordinate systems for measuring vibration exposures and biodynamic responses have been standardized, but they are not actually used in many studies. This contradicts the purpose of the standardization. The objectives of this study were to i

The performance of Type I industrial helmets for fall protection is not required to be tested in standardized tests. The current study analyzed the fall protection performance of Type I industrial helmets and evaluated if the use of a chin strap and

The anterior and posterior iliac spine markers frequently used to define the pelvis, are commonly occluded during three-dimensional (3D) motion capture. The occlusion of these markers leads to the use of various tracking marker configurations on the

It has been generally hypothesized that the biodynamic responses to vibration such as vibration stress, strain, and power absorption density of the human finger tissues are among the major stimuli that cause vibration health effects, because mechanic

The helmets used by construction site workers are mainly designed for head protection when objects are dropped from heights. Construction helmets are also casually called “hard hats” in industries. Common construction helmets are mostly categoriz
