Actually, no. Carpal tunnel syndrome has not been linked to keyboard usage, improper or otherwise. http://www.ninds.nih.gov/disorders/carpal_tunnel/detail_carpal_tunnel.htm http://www.nhsdirect.nhs.uk/articles/article.aspx?articleId=88§ionId=9 You likely mean RSI (repetitive strain injury), also called CTD (cumulative trauma disorder) or RMD (repetitive motion disorder). That issue is a lot bigger and a lot muddier. But current wisdom is, you want your wrists to be flat and supported, not raised *or* lowered. Simply enough, avoid anything that puts a strain on your body repeatedly (whodathunkit?). Holding your hands in the air above the keyboard is a strain. For that matter, current wisdom is that doing just about anything repetatively and/or for long periods of time is bad for you. Fancy chairs won't help; the real problem is that holding any one position for hours at a time is bad for our bodies. Take frequent breaks. Move your arms and wrists. Get up and walk around. Don't fall into harmful patterns. http://www.ninds.nih.gov/disorders/repetitive_motion/repetitive_motion.htm http://dohs.ors.od.nih.gov/ergo_computers.htm http://www.google.com/search?q=repetitive+strain+injury http://www.google.com/search?q=repetitive+motion+disorder http://www.google.com/search?q=cumulative+trauma+disorder -- Ben _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
