All, I recieved this through a private board I read here at Carnegie Mellon University. I have forwarded it to other boards, and though I should forward it to this one as well. It appears to have been forwarded a number of times (in fact, you may have seenit already), so I've deleted a few of the headers and left only the bare information. This message should be read by as many people as possible. I know at least one person with this problem, and every time it is posted, someone says "yeah, I had that", so it must be pretty common. Anyway, have a read. Healthily, Jeff Brown All responses, flames, etc. to jb8x+@andrew.cmu.edu Functional Disclaimer: Please give all credit for the above statements to me.

Those of you who know nothing of Carpal Tunnel Syndrome should definitely read this. Those of you who have heard of it might want to read it anyway, as it includes some helpful hints for prevention. (Background information: 6.170 is an undergraduate software engineering lab at M.I.T.) -chris ---------------------------------------------------------------------------- This message has very little to do with 6.170, but since you will all be doing intense ammounts of typing this term and probably in the future, you should know about Carpal Tunnel Syndrome. I apologize to all those who already know about this. Carpal Tunnel Syndrome is an advanced form of Forearm Overuse Syndrome and tendonitis in the wrists. Basically, the bones in your wrist form a 3-sided tunnel (called the Carpal Tunnel). Your tendons, blood vessels and nerves pass through this tunnel. If your tendons swell up too much, it can pinch your blood vessels and nerves, causing numbness in the fingers. If it is ignored, permanent damage can occur. Even if it doesn't advance to the numbness stage, it is extremely painful and can render your hands pretty useless. In the past, mostly factory workers were the victims of this type of injury, which is caused by repetitive motion (aka Reptitive Motion Syndrome.) However, most cases now are related to computer use. I developed this infliction last year when i was taking 6.170. I developed pain in my wrists, that sometimes ran from my fingers all the way to my elbow. I was stupid and ignored it, thinking it would go away as soon as the class was over and i got to take a rest from typing. I rested it 3 weeks and it seemed fine until i started typing again at my job. The pain got worse and worse until i could barely write, or even tie my shoes. Then one day i woke up and i couldn't feel the tips of my fingers. I ran to the med center. I had both my hands in casts, and then splints for the remainder of the summer. Even though I've taken almost 6 mos. of rest from typing, i still experience severe pain whenever i type. (Not good news for a 6-3). Almost a year later, I am taking strong anti-inflamatory medication and pain killers (equal to 7 Advil) everyday. I am in physical therapy 3 times a week getting ultrasound treatment, and i ice my wrists all the time. My orthropedic doctor has diagnosed it as chronic, although we are trying everything to correct it, possibly even surgery. Basically, I'm trying to say that this is VERY SERIOUS. It can really interfere with your career... And it CAN HAPPEN TO YOU!!! My doctor says he currently has 15 cases of students with chronic variations of Forearm Overuse Syndrome. I probably got this because I typed wrong. Do the following to avoid developing CTS/Tendonitis: 1) Keep your wrists UP while typing. DO NOT PUT YOUR WRISTS ON THE TABLE!!! It might seem uncomfortable at first, but you'll get used to it. KEEP YOUR WRISTS UP! KEEP YOUR WRISTS UP! This is VERY important. 2) If you feel your wrists might need support in the "up" position, put a pillow under them or something. 3) Make sure you are using the Shift Keys properly. Do not hit the shift key with the same hand you hit the other key. 4) Try switching your mouse to the left side now and then if you are a righty, and viceversa for lefties. There are lefty configured workstations in 38-344. 5) Make sure that the key board is low enough. It should not be too high, so that you would have the temptation to rest your forearm on the table. If the keyboard is too high (as it often is in Athena clusters) put the key board in your lap. Good posture while typing can make an amazing difference. 6) If you experience any pain, ice it and Go to the Med Center. 7) If it hurts too much to type, for God's sake, give your hands a rest. I worked through it last year, and I got a good grade in 6.170, but i'm not sure if that good grade was worth screwing up my hands for possibly the rest of my life (not very optimistic, i know.) I'm currently looking into Law School since I don't know what else I'd be able to do if I can't get rid of this... :) Party On and Keep your Wrists Up, [name withheld] ---------- - -- ------- End of Forwarded Message
