Carpal Tunnel Syndrome
About ten years ago, when I worked as a programmer at IBM, my wrists began to get very sore and painful. Every night I had to come home and ice them down to ease the pain and swelling. The doctor said it was Carpal Tunnel, and I would need drugs, therapy and perhaps surgery to treat it. But I had another plan in mind…

What is Carpal Tunnel?
Carpal Tunnel Syndrome is the result of a compressed nerve at the wrist. This nerve, called the median nerve, delivers sensations to the thumb and all fingers except the pinkie. The Carpal Tunnel is actually the passageway of bones and ligaments of the wrist where the median nerve passes through. When this nerve is compressed, it may result in numbing sensations or even pain. It can be debilitating, depending on the severity of the compression.
Symptoms of Carpal Tunnel Syndrome may include pain, tingling, and numbness. Some people experience a lack of grip strength, or a burning sensation in the area of the wrist and hand. People with severe cases may experience the inability to sense hot and cold, and may loose muscle in the thumb.
Why Does Carpal Tunnel Happen?
Carpal Tunnel Syndrome can be the result of long periods of time with your wrist and arm being compressed or positioned in the same way. It could also be the result of an injury occurring at the same location. Sleeping with your wrists flexed, using a mouse and keyboard without rest, or falling and landing on your wrists might result in Carpal Tunnel Syndrome. Repeatedly doing the same thing, over and over, and without rest, can result in injury to the wrist and hand in many various other ways, but one of the most serious is Carpal Tunnel Syndrome.
Women are known to be more susceptible to this injury than men, though it might be because the arms and the nerves are smaller. The workers at biggest risk are assembly line workers who do repeated tasks over and over, typists and data entry personnel. If you spend a lot of time at a computer you should take steps to avoid this injury.
This potentially debilitating injury can be avoided. Those who work in an environment that requires long periods of using a cash register or computer, picking up and putting down a telephone, or anything that causes repeated strain on the forearms and wrists should be careful to take plenty of breaks. Five minutes every half hour can save you from a lot of pain later on. All it takes is a little time to flex and then relax the muscles in your wrists.
Treating Carpal Tunnel Syndrome
Treatment, if caught early on, includes a lot of rest. Doctors recommend up to two weeks of relaxing the wrist before getting back to work. You should see a doctor immediately when you feel symptoms, as severe cases might require surgery. Some surgical procedures can help, but it is used a last resort. You also want to make sure that diabetes or arthritis isn't playing a factor, and to treat those first if they are. Several types of drugs are often given for patients who catch it early, which will help decrease swelling and reduce pain. Exercise and alternative methods of treatment, like acupuncture and massage therapy, has also been recommended.
You may remember that in the beginning of this article, my doctor prescribed drugs, therapy and surgery to treat my carpal tunnel. That was unacceptable to me, so I immediately bought one of those ergonomic keyboards that are split or angled so your hands rest more naturally on the keys. It took a week or so to get used to it, but my symptoms disappeared almost completely! On a standard keyboard, you are forced to rotate your wrists outward, which puts more pressure on the carpal tunnel area. The cushioned palm rest and the special shape of the ergonomic keyboard helps you position your wrist and fingers to minimize that pressure and repetitive stress.
It's been more than ten years, and I only have trouble when I use a regular keyboard, or do something stupid like swinging a sledge hammer. The keyboard I use now is the Microsoft Natural Ergonomic Keyboard 4000. The Comfort Curve Keyboard 2000 is another design with a curved key layout. It's similar to the Ergo 4000, but doesn't have all the ergonomic features. You might find it easier to get used to, though, since the keys are positioned more like a traditional keyboard. An ergonomic mouse, such as Perific's Wireless Dual Mouse can help too. Use of these devices can be a big help, but don't depend on them alone. Instead, continue to take breaks and relax when you can.

My husband bought that keyboard for my office computer when I started to avoid using the computer because it was so painful. After reading more about carpal tunnel I put a box under my desk for my feet and adjusted my chair to correct my posture when sitting at the keyboard. The keyboard and box remind me to sit up straight. The pain disappeared before my scheduled doctor appointment. |

The vitamin B-6 in 50mg dose every day will go a long way to relieving the problem. Also helps with arthritis and calcification in the joints of the fingers. I was taught an odd but very effective way to relieve the muscle tension. Go to a Physical Therapist for instruction. It works on the immediate problem and does help in the long run. It requires extending the arm and hand, tensioning the muscles in the arm, twisting the arm, and then applying pressure from the opposite hand on the thumb. |

I solved my carpal tunnel problems by switching my ordinary mouse to one by Evoluent. It puts the hand in an entirely different position. I got it about two years ago, and my symptoms disappeared. I'm very happy with it. Just google Evoluent--and you'll be directed to the company. |

I agree with brenda's comment, although I found an easier solution: I just bought an office chair with an adjustable armrest, and made sure that it was adjusted at the same level as the surface on which I run my mouse. This way, my entire arm rests on it as I work. Never a pain again!!! |

At the first sign of repetitive motion troubles, in both my right wrist and elbow, I purchased one of those ergonomic keyboards which I hope will be replaceable when it wears out. It has the 6 in the wrong position, but I live with that, because I don't do many numbers there, using, instead the keypad. One thing this keyboard has that I like is a touch pad. That eliminates the constant reaching for the mouse. I place the keyboard on one of those lap pillows designed to hold laptops, and use an elevated gel wrist support under my right wrist, and that supports my whole arm most of the time. The important thing to remember, for those of us with this problem, is to keep the knees, the hips, and the elbows at right angles, which, in many cases means either lowering the chair or providing a foot rest. Anyway, this latest combination has worked for me for several years. |

Another possibility for mousing that doesn't seem to have the same impact on the hand and wrist is a graphics tablet. They take a little getting used to, but because you're holding a pen rather than resting the weight of your hand or arm on a mouse, they do seem to help. My RSI problems haven't come back since I got my first graphics tablet about four years ago... |

I've had a theory for years, about Carpal Tunnel Syndrome. I've used computers since the first TRS-80 about 30 years ago. Back in those days, I spent my evenings and all of my weekends on the computer. Since retiring 14 years ago, all my time has been spent on the computer. If anyone is a candidate for Carpal Tunnel, it would be me, but I've never had a trace of it. |

My physio looked at my work station and said "No wonder". I had the mouse on the edge of the desk and my forearm completely unsupported. He changed it by pushing everything back on the desk so that I have my whole forearm resting on the desk when using the mouse. He explained that doing this makes you use your big shoulder muscles for the mouse, not the wrist. I was in agony until I tried it (3 years ago), but I haven't had any pain since. |

I came to the Carpal Tunnel Syndrome article by way of a keyword search on this site. (I've been with the Tourbus e-mail list a few years now.) My particular interest trigger here was Bob's mention of laptop computing as 'green computing', coupled with someone else's observation that his experience of wrist problems was exacerbated by use of a laptop. My own touch-typing training was in 1980, and the Windows adjustable keyboard has helped lessen my experience of wrist injury rather than increase it. (I used to tense my wrists too much on the manual office typewriter, and yet experienced electric typewriter keyboards as almost totally uncontrollable. No such problems with Windows adjustable keyboards.) Maybe an important reason for my not having wrist problems with conventional desktop keyboard or mouse is that -- like the 9 April correspondent -- I have my elbows lower than my wrists? |
