Computer mouse that prevents or treats carpal tunnel syndrome and methods of use

A new computer mouse is disclosed to prevent strain injuries to the hand and wrist and prevent or alleviate the symptoms associated with Carpel Tunnel Syndrome (CTS) for those who are repetitive users of computer mouse devices. The mouse is designed to leave the carpal tunnel of a user of the mouse substantially open, thus precluding tunnel narrowing and the symptoms resulting therefrom. The mouse is also designed to maximize comfort of the user, alleviate wrist bend associated with use of the mouse, and is adaptable to different size hands.
