There is no better place to come. Marlborough will indicate his top tip for the day in traditional style, with any other notable selections highlighted with “nb.”
So come back every evening for Marlborough’s daily selection. Good luck. When working from your home office, you may tend not to take as many breaks as if you were in a traditional office. You may find yourself working for hours before getting up from your chair, as the interruptions are normally fewer to distract you. Because of this, it is critical that you take care of yourself – and arm yourself with the basic ergonomics to prevent or at least minimize any physical strain due to computer work.
Here are 12 tips for setting up an ergonomic computer workstation:
1. Use a good chair with a dynamic chair back and seat pan. Would you please sit back and use it instead of leaning forward
2. Position the top of monitor casing 2-3″ (5-8 cm) above eye level
3. Use a no-glare screen and an optical glass anti-glare filter where needed
4. Sit at arm’s length from the monitor
5. Place your feet on the floor or stable footrest
6. Use a document holder, preferably in-line with the computer screen
7. Keep wrists flat and straight about forearms to use keyboard/mouse/input device
8. Your arms and elbows should be relaxed and close to your body
9. Center your monitor and keyboard in front of you, so you are not turning to use them
10. Use a negative tilt keyboard tray with an upper mouse platform or downward tiltable platform adjacent to the keyboard for the best wrist angle
11. Use a stable work surface and stable (no bounce) keyboard tray
12. Take frequent short breaks (micro breaks)
Ideal typing posture: Negative slope keyboard support
In the ideal typing posture, both static and dynamic muscle loads are minimized. This posture is achieved when the keyboard is below seated elbow height, and the keyboard base is gently sloped away from the user so that the key tops are accessible to the hands in a neutral posture. The arms, shoulders, neck, and back can relax in this position, especially during brief rest pauses. Also, in this slightly reclined sitting position, the low back rests against the chair’s lumbar support. The elbow angle is opened to promote circulation to the lower arm and hand, the abdominal angle and the popliteal angle (behind the knees) are opened to promote blood circulation. The feet rest firmly upon the floor.
Desktop keyboard –
Typing at a keyboard on a desk is a common work posture for many computer users. In this position, it is difficult to maintain the wrist in a neutral posture because the forearms sag as they tire, which puts the wrists into greater wrist extension. Also, most users have to work with their elbows flexed, which can compress the median and ulnar nerves at the elbow and restrict blood flow to the hands. Working with the forearms sloping up increase muscle loads in the upper arms, shoulders, and neck. Working in this position for more than 3-4 hours invariably leads to muscle fatigue.
Conventional keyboard tray –
Typing at a keyboard on a conventional articulating keyboard tray can increase postural problems for users. Working with the keyboard more steeply angled on the tray is common for many computer users. In this position, it is also difficult to maintain the wrist in a neutral posture because the forearms sag as they tire, which puts the wrists into greater wrist extension. Studies have failed to show that conventional keyboard trays substantially improve wrist posture.
Of course, there are other ergonomic factors, such as proper lighting, ventilation, mouse use, furniture heights, styles, and phone equipment, to name a few. Be sure to research what will be best for your specific situation and budget. Take care of your body now, and it will take care of you in the future.
