Abstract
Keyboard constructions and methods are described which force or provide feedback for finger action that will enhance stability of the carpal tunnel tendons. Methods are described for reducing incidence of carpal tunnel syndrome in a person who operates a keyboard, involving monitoring actuation of switches, measuring a depression characteristic, comparing the depression characteristic with a predetermined value, and creating a signal corresponding to the number of keystrokes executed with a depression characteristic less than the predetermined value. A method is also described for detecting unphysiologic tendon translation denoting tendon instability in the carpal tunnel of a person who engages in repetitive hand motion.
