Narrator: This is Science Today. A new computer keyboard design has been found to reduce hand pain similar to carpal tunnel syndrome. David Rempel, who directs the University of California Ergonomics Program, says the design they studied features a lever arm underneath the keyboard.
Rempel: From the outside, the keyboard looks identical to any keyboard in front of a computer but if you put your fingers on the keyboard and press down, the key caps feel a little looser than the conventional keyboard and when you start typing, the impact at the end of when you press the key all the way to the bottom isn't quite as sharp. It's almost like it has a little shock absorber at the bottom of the keystroke.
Narrator: Rempel found hand pain in people randomly assigned the lever keyboards significantly decreased compared to those using conventional ones.
Rempel: This raises the possibility that someone seeing a physician for hand pain, their physician might recommend a three month use of an alternative keyboard like this to see whether or not it improves their hand pain.
