Different computer tasks affect the exposure of the upper extremity to biomechanical risk factors

Article Abstract:

A repeated measures laboratory experiment was completed with 30 touch-typing adults, who completed five different computer tasks, in order to determine differences in biomechanical risk factors across computer tasks. Comparing different types of computer work demonstrated that mouse use is prevalent in most computer tasks and is associated with more constrained and non-neutral postures of the wrist and shoulder as compared to keyboarding.

Changes in upper extremity biomechanics across different mouse positions in a computer workstation

Article Abstract:

A repeated measure laboratory study aims to determine differences in biomechanical risk factors across different mouse positions within computer workstations. Results demonstrate that there are differences in the exposures to various biomechanical risk factors, which are dependent on where the mouse is positioned within the computer workstation.

Accuracy and feasibility of using an electrogoniometer for measuring simple thumb movements

Article Abstract:

The accuracy and feasibility of using an electrogoniometer for measuring simple thumb movements are determined. The results found that electrogoniometer have the utility for studying thumb movements during mobile phone use and it can also be used to evaluate other thumb-based input devices.
