    Chiou S ;
    Long D
    2000/07/30 | National Institute for Occupational Safety and Health (NIOSH)
    Drywall lifting and hanging tasks require workers to handle heavy and bulky drywall sheets and maintain awkward postures to install materials onto the wall or ceiling. Previous studies indicated that drywall lifting and hanging tasks cause more fall-related injuries than any other tasks. Activities associated with these two tasks often result in mu ...

    2000/07/30 | National Institute for Occupational Safety and Health (NIOSH)
    Welders have been reported to experience musculoskeletal symptoms and pain in the shoulder, neck, and low back regions (Torner et aI., 1991). Welding occupations involve prolonged static exertions with awkward postural stresses that may be exacerbated in confined spaces. This study examined a specific welding job at a shipyard where confined space ...

    Overexertion injuries comprise the largest category of nonfatal injuries among construction groups which include scaffold erectors. These injuries typically occur when the biomechanical stresses associated with tasks such as lifting, carrying, pushing, etc. exceed the workers' strength capacity. This study was conducted to estimate the whole body i ...

    Inputting to a notebook computer (NPC) can differ from inputting to a desktop style computer. NPCs are self-contained, so if no peripherals are used, the user works with the keyboard layout and style and location of pointing device provided by the manufacturer. In contrast to standard external keyboards, there are few redundancies provided on an NP ...

    Work-related MSDs remain one of the most serious problems facing the American workforce. A large body of widely accepted, consistent scientific studies from a variety of disciplines has shown that there is a clear relationship between work factors and MSDs. This base of scientific information is much more extensive than that typically available for ...
