Computer and visual display terminals syndrome is a constellation of symptoms ocular as well as extraocular associated with prolonged use of visual display terminals. This syndrome is gaining importance in this modern era because of the widespread use of technologies in day-to-day life.

This study used surface electromyography (EMG) to examine the percent of maximum voluntary contraction (%MVC) of the upper trapezius, the flexors of the wrist/fingers and extensors of the wrist/fingers during Video Display Terminal (VDT) mouse use with the mouse positioned either next to the compute …

The present invention relates to a computer mouse, and more particularly, to a VDT syndrome prevention computer mouse device intended to prevent diseases on the wrist when using the mouse...

2000年11月1日 · A new-concept VDT workstation chair with an adjustable keyboard/mouse support was proposed to minimize the physical discomfort and the risk of cumulative trauma disorders (CTDs) at work sites. A three-dimensional human modeling tool (SAFEWORK ® ) was used to design the new chair which satisfies the anthropometric specifications of the Korean ...

The effects of mouse use on the forearm and wrist were evaluated among occupational groups in a laboratory setting using pertinent musculoskeletal and skill proficiency outcome measures. An alternative mouse was designed that would reduce the risk of forearm and wrist cumulative trauma disorder (CTD).

The present study showed that VDT usage at work was associated with an increased risk of headache/eyestrain. Additionally, the use of VDT increased the risk of suspected CVS patients in white-collar workers and pink-collar workers.

Risk factors present during forearm pronated (FP) mounse use that were associated with the development of forearm and wrist cumulative trauma disorders (CTD) were investigated. A forearm neutral (FN) mouse design eliminated the postural and joint motion risk factors and reduced some of the muscular demands associated with the postural risks.

The purpose of this study was to examine shoulder and arm muscular fatigue induced during visual display terminal (VDT) keyboard use tasks. Electromyography signals were recorded from the right side upper trapezius, deltoid and extensors of the wrist/fingers during VDT task and during isometric contractions task respectively.

Neck stiffness and/or pain was associated with raising the shoulders during VDT work, the unsuitable shape of the computer mouse for a hand, and the inconvenient arrangement of the mouse in relation to the body. Hand or arm strain and/or pain were associated with the arrangement of the mouse and inappropriate height of the desk.

This paper presents a new approach to preventing Mouse Arm Syndrome, focusing on the impact of mental stress and physical demands associated with computer mouse use.
