View Full Version : RSI! (repetitive stress injuries)

With the amount of time being spent on the computer today, I thought I might introduce the topic of RSI since I don't see it discussed. This will help keep YW posters posting and possibly prevent such injuries from ever happening in the first place. I included a poll because polls can grab attention. Here are some informational links about RSI and other links for a pain free computer experience.


There are many good articles on this site:

like these:

information on mouse use:

If you have the 1998 Computer Currents article "RSI 101," please post it. I found that article very accurate and useful.

My own tips (which worked for myself and some others I've worked with):

1. Relax your shoulders and have the keyboard at a level so that your wrists are straight and elbows around 90 degrees or a little closer to your lap rather than higher up. I've found that many corporations have the users' keyboards too high. Higher is bad for most users!

2. Do not type harder than you need to.

3. The top of your video display should be at eye level.

4. You should not have to lean over to reach a keyboard or mouse.

5. Take breaks especially when you get tired and take breaks even if you are NOT tired.

6. Stop immediately if you feel sore.

7. If you must read even when your eyes are tired, print things out on paper with a decent sized font.

8. Make sure your refresh rate is something over 60Hz if you are using a CRT (a monitor). 60Hz can lead to tired, sore eyes! If you have a monitor capable of 85Hz+ without causing problems with the monitor at the resolution you currently use, you owe it to yourself to use 85Hz. If the safe max on your monitor is 70Hz, 72Hz, or 75Hz use it. Don't compute with sore eyes.

9. If you are already in good ergo-land, don't make drastic changes if you feel no pain. Example: don't use any ergo keyboard if you are having no problems with a normal keyboard.

10. Got mouse pain? Try a trackball. Try a touchpad. Try a glidepoint. Try an ergo joystick mouse (seriously). Alternate between the ones that hurt the least. Don't continue to use a mouse unless it gives you the least pain.

11. If you do a hell of a lot of scrolling with big spreadsheets, try a dual monitor or triple monitor setup with the appropriate videocard. More resolution on the same monitor may help, up to a point. Too high a resolution and you will be squinting. They key here is, the more information you can see on your screen (more resolution or more screens to use), the LESS SCROLLING VIA MOUSE OR KEYBOARD YOU NEED.

Anyway, hope this will help someone.

Disclaimer: I'm not saying these things will work for everyone.

what exactly does the refresh rate on the monitor do? i just changed mine from 60 to 85.

This is the vertical re-draw rate from what I understand. It can be very hard on the eyes at 60Hz. At 59Hz, it can become unbearable. The average human can't tell the difference at 60+Hz so most CRT's are at least 60Hz. LCD's are different. The analog LCD's generally run at 60Hz and they usually don't hurt peoples' eyes or make their eyes tired.

You can often see the flickering on the news when the camera's framerate is not tuned to the monitor's refresh rate. The monitor will have a line that appears to go up or down on the screen depending on if the camera is too fast or too slow.

By the way, there is usually a recommended refresh rate and a maximum refresh rate for your monitor. I tend to go for the maximum but I suspect that it may reduce the life of the tube.

Oh yeah, I forgot to mention to choose a "non-interlaced" mode. Interlaced modes are no longer used today because they hurt the eyes.

Well I was going to make a perverted joke but didn't since you were serious about the topic. I can still make the perverted joke if you would like.

Eh... I have no idea what you people are talking about. I must be the most computer-illiterate person here.

Back to my abacus..

Perverted jokes are cool. I could use some action in this forum to make more people aware of RSI.

RSI is repetitive stress injuries. It's something you can get if you use the computer a lot, especially if ergonomics are bad. Read some of those articles n stuff I posted. It is very common these days.

Oh yeah. Eye strain is not an RSI but I thought I would include it because it's important!

I don't have it, and am not really worried about it. On the other hand, if possible I do go out of my way to make sure I'm comfortable when I'm working at the computer. I haven't had too much trouble in the past getting companys to pay for little things like ergonomic keyboards, trackballs and glare filters. It only makes sense for the employer to want their workers to be more comfortable and thus likely more productive. I do think I've had some places mind a little with my previous excessive printing habits, but they've never outright said anything. It's not like I was printing personal stuff, just work related. Btw, I disagree with statement #9, I personally think ergonomic keyboards are great and feel more natural, but I don't have any problems with regular keyboards.

Yes, a smart company will change things for you if you say it's not comfortable. They should protect their investment!

Yes, I think most prefer ergo keyboards. In #9, I meant don't make too drastic a change if you are not hurting. You could end up hurting for trying something more ergonomically correct. If it ain't broke, don't try and fix it. :D

yes people please type with good hand postures. get a piano player to teach you if you don't know. the surgery you need to get when you have RSI is said to be extremely painful!

My friend had to go through surgery because of the pain.

if you overuse your wrists, ice 'em for 30 seconds every 30 minutes or so!

That's probably from stuff other than computer use. :D
