So you finally managed to get your home computer linked up to the Internet over Christmas.
And how many hours have you spent clicking away since then in a desperate attempt to use up the free time that came packaged with your first month's subscription?
It is time to put down the mouse and give those wrists a rest. Carpal tunnel syndrome, aka repetitive strain injury, aka cumulative trauma disorder, may be strictly for those with eggshell personalities (as a judge once famously and stupidly put it in dismissing a damages claim), but it is still cripplingly painful.
All regular keyboard users should know a little bit about CTS, and perhaps the best place to start is to Ask NOAH. The excellent New York Online Access to Health offers a copious collection of information and sources on the subject, organised and presented in its usual accessible style.
Less extensive but more eye-pleasing are Health Philadelphia's Repetitive Stress Pages, which come complete with online video and helpful advice on how to adjust your workstation (or desk and chair as we traditionalists call them). Health Philadelphia estimates that a quarter of all work days lost due to illness can be attributed to repetitive stress injuries, while someone suffering carpal tunnel syndrome will on average be away for 30 days, compared with just 20 days for a fractured limb. Unfortunately, it offers no source for these figures.
Both NOAH and Health Philadelphia are good on treatments, but for advice on prevention look to the American Academy of Orthopaedic Surgeons' page on carpal tunnel exercises. And if you want to get militant, the publishers of the Typing Injury FAQ Home Page are organising an international RSI Day, when we can go out and wave our arms in protest - assuming someone can find a date not already bagged by one interest group or another.
