Office Ergonomics – Current Research
The more recent research regarding office ergonomics is in support of:
• Alternative mouse designs i.e. vertical, joystick
• Arm supports
• Adjustable chair
• Keyboards
-reduced impact force of keys
-split design/geometry
Although not yet supported by research, other changes that Occupational Health organisations advocate are:
• Screens that are positioned to avoid glare from windows & lights
• Use of document holders near the screen instead of looking down onto the desk
• Desk height that reaches 1cm below the elbow when the worker is typing
• Avoiding sustained reaching with the arms or allowing the chin to protrude towards the computer monitor
• Adjustments to chair/desk specifications for very tall or very short workers
Approximate Workstation Guidelines
• Monitor at eye level
• Seated close to desk with back against the backrest
• Elbows bent slightly greater than 90 degrees
• Wrists straight and in line with forearms
• Hips bent so they are greater than 90 degrees
• Feet on floor and using footrest if worker cannot reach
Equipment changes alone are not enough to alleviate symptoms in most cases. Equipment changes are most effective if implemented with
• Breaks: getting out of the chair 2-3 times per hour
• Exercise: the worker should be participating in some form of regular exercise
