it would be really, really interesting to me if the keyboard/mouse use connection to carpal tunnel syndrome proves to be very poor: "'Can keyboard use then be considered an occupational risk for developing carpal tunnel syndrome? From our data it seems unlikely,' the study said. 'But based on other studies, we cannot exclude the possibility that very intensive and repetitive keyboard use could be a risk factor ... however our opinion is that it is not an important one,' the study concluded." that all having been said, i'm in general dubious of all these kinds of studies (only 20 hours a week?). . . (from rae) a related study up at humanscale about an ergo study: "Findings of a two-year study investigating health problems associated with use of non-keyboard input devices (NKID) are presented. The research used a combination of methods to determine the extent to which different NKID are currently in use, how they are used and the problems that result." i haven't finished ready it so far, but i'm curious about trackpad vs mouse use; i use a trackpad almost exclusively these days, but i would not describe my usage as "continual" anymore.
