Effect of Four Computer Keyboards in Computer Users with Upper Extremity Musculoskeletal Disorders
Eighty computer users with musculoskeletal disorders participated in a six-month , r and omized , placebo-controlled trial evaluating the effects of four computer keyboards on clinical findings , pain severity , functional h and status , and comfort . The alternative geometry keyboards tested were : the Apple Adjustable Keyboard ™ [ kb1 ] , Comfort Keyboard System ™ [ kb2 ] , Microsoft Natural Keyboard ™ [ kb3 ] and placebo . Compared to placebo , kb3 and to a lesser extent kb1 groups demonstrated an improving trend in pain severity and h and function following six months of keyboard use . However , there was no corresponding consistent improvement in clinical findings in the alternative geometry keyboard groups compared to the placebo group . Overall , there was a significant correlation between improvement of pain severity and greater satisfaction with the keyboards . These results provide evidence that keyboard users may experience a reduction in h and pain after several months of use of some alternative geometry keyboards
