NWA-PCUG 04/2000 NewsLetter Article 18861 N. Hwy 112, Springdale, AR 72762-9303 Ken's Korner Take Rest Breaks, Exercise To Prevent Computer Ailments By Ken Fermoyle, TUGNET Between us, my wife and I offer a catalog of the physical ills caused by long hours of working on computers: repetitive stress injury (RSI), neck pain, backaches and vision problems. Liz underwent surgery twice for carpal tunnel syndrome and still has frequent wrist and hand pain. I have suffered from aggravated neck and back injuries. My vision has deteriorated from 20 years of staring at a monitor, although admittedly age-related macular degeneration (AMD) and cataracts have been more damaging. The sad truth is that if we knew 15 years ago what we know now, these problems need not have occurred. Or if they had, they would have been less severe. Even sadder is that prevention of many computer-related ailments is neither difficult nor especially time-consuming. Frequent rest breaks are vital, says my chiropractor, Kurt W. Rice, who is also my son-in-law, God bless him. (He has helped me more times in recent years with neck and back problems than I care to remember!) The breaks needn't be lengthy. Dr. Kurt recommends that we get up from your chairs every half-hour or so, stretch our backs and walk for a minute or two. Other experts offer different opinions about frequency and duration of breaks but all agree that they are vital. Sitting and working at a computer creates more tension and stress on muscles, nerves, tendons and joints than most of us realize. Our bodies fight gravity every minute that we're seated. Breaks alleviate this tension and stress. To prevent the dread carpal tunnel syndrome, during your break let your hands go limp at the wrist and wiggle them vigorously in what some call "the clerk & typist exercise." Some people use voice recognition programs to cut down on their need to use the keyboard and mouse. I find that difficult; after more than 50 years of banging away at typewriter and computer keys, dictation comes hard to me. Now that voice recognition is improving and more reliable, however, I've resolved to use it more often. A major benefit is that you can use a microphone or headset while standing or even lying down. I plan to try dictating drafts, then to rewrite and edit as necessary from the keyboard. Vision experts warn that we should take "eye breaks" even more frequently. Every 10 or 12 minutes, look away from the monitor at objects 10 to 12 feet away. When I'm working with a word processor or any other program that allows me to increase type size easily and temporarily, I do it. This prevents squinting and straining to see my work. It also allows me to sit up straight, not bent over the keyboard I mentioned my neck and back injuries earlier. My neck problems began about 17 years ago. I was riding my bicycle when a large tree limb broke off and fell on me. (Fortunately I was wearing a good helmet or the freak accident might have killed me.) That caused some damage, which increased with age and was aggravated by working on computers. The pain got so bad I could not turn my head to either side more than 12 or 15 degrees. Dr. Kurt came to the rescue, with manipulation, ultra-sound and heat packs. He recommended several simple exercises, which I try to do regularly. My back injuries were computer-related. The first came when I installed a second drive in one of our machines. I crawled under a desk to get at the computer case. After removing all the cables, I tried to lift the box and slide it out to where I could work on it, not waiting to shift to a position that would give me more leverage. Bad move. I heard a pop and was in instant agony. It took several weeks of Dr. Kurt's ministrations to recover from that one. I injured it again in October 1999 after conducting my monthly desktop publishing/word processing SIG. I took a computer and 17-inch monitor out of a car trunk with a high lip that made it impossible to lift them properly. I had to bend and lift with my back and pop, there it went again! This time, recovery took more than even longer. I mention these details to make a point. The first instance was pure accident. No way could I foresee that a brittle, rotted pepper tree branch would break off and fall just as I pedaled under it. The second injury occurred because I didn't take time to position myself properly. The third case was avoidable too; I should never have tried to lift heavy objects out of that particular car truck. Trouble is, I forget my hard-used back is more vulnerable now than it was even 20 ago, and I think many of us who have reached senior citizen status do the dame. I just caught myself in a no-no a few minutes ago. I wanted a book from a built-in shelf high and to the right of my home office workstation. I started to reach up, twisting my back at an awkward angle. Various muscles prepared to scream in protest, so I did what I should have done in the first place. I moved my chair out of the way, got a low stool I keep folded behind the door, set it firmly in place and climbed up to find the desired book. It took a few extra minutes, but it kept me from aggravating my previously- injured back. The book, by the way was Zap! How your computer can hurt you and what you can do about it. Written by Don Sellers (edited by Stephen E. Roth) and published by Peachpit Press in 1994. It's now out of print but Peachpit has a condensed version, 25 Steps to Safe Computing, also by Sellers, that is still available for $5.95. (Remember that Peachpit offers discounts to user group members.) Either would be a good addition to your library. You can also check out my Website at www.zyworld.com/wordsmithken . I'll be adding links to several computing safety sites there. Meanwhile give yourself, and your body, a break at least once every half- hour!
