World's Best Selling Vertical Keyboard
  Deviation
   

  

Most of us learned to type on a standard, flat keyboard. The keys are all in nice, neat rows. Unfortunately, that means we have to twist and turn our hands to line them up with the keys in order to use the keyboard. Learning to use this kind of keyboard is very much like learning to smoke. It was uncomfortable the first time you tried it, but you gradually became used to it over time (and it is still bad for you even once you get used to it).

If you hold your wrists straight, then move your hand so that the little finger moves out and (pretend) back toward the elbows. This is called ‘ulnar deviation’ (you don't have to remember the terms to understand what's happening).

Holding your wrist in any position other than straight causes what physiologists call ‘static muscle loading’, or what you and I might call ‘constant tension’. Side effects of this include increased muscular energy expenditure, reduced muscular waste removal, and eventual discomfort or injury.

Eliminating deviation of the wrist is the inspiration for lots of attempts to design ‘ergonomic’ keyboards. As we saw in our previous illustration (click here if you didn’t see it yet) this can result in simply transferring the problem to another area. There is only one ‘ergonomic’ design that is also ‘orthopedically neutral’ and eliminates the ulnar deviation by design. (Hint: think SafeTypeTM)

Note: The Safetype™ keyboard is not offered as a cure for any medical condition. If you have been typing on other keyboards, it may be possible that an injury process which has already begun could become apparent after you change keyboards. The manufacturer makes no curative or medical claims for this device. Every keyboard user should take appropriate breaks.
