Re: Rest supports
Do you have a chair with arm rests? If so, make sure they (the arm rests) are at the same height as the surface of your table.
Also using a table with rounded edges eases the use of keyboard and mouse.
I found that those gell-pad thingies cause more RSI than they solve because they limit the downward strokes you can make with your mouse and they force your wrist in an uncofortable position.
Also, very important, make sure your mouse sensitivity isn't too high. Higher sensitivity means you have to aim more precise with your mouse. High precision hand-work for longer periods of time is very straining for your wrist.
Anyways, here's some guidelines I got at the place I worked before.
- monitor at eye-height
- adjustable chair: both armrests and sitting height
- feet flat on the floor, upper and lower leg make a 90 degree angle (determine sitting height)
- armrests at the same height as the table surface, shoulders should be at normal height when resting arms at rests.
- Comfortable table edges
If you have all this, try taking your hands off the mouse and keyboard when you are reading stuff.
Taking micro-breaks helps too. Every 5 minutes, 30 seconds hands off. A tool called workrave can help you with that.
Doing non-stop keyboard work for long periods of time is a big no-no if you want to stay healthy. The micro-break thing helps tonnes, but it all starts with a good work environment.
