What is the problem with the design of standard computer keyboards?
Alternative computer keyboard designs have been available for over 30 years. The main concern with the design of the conventional computer keyboard is that people bend their hands to the side when they are typing on the keyboard. This lateral bending of the hands is called ulnar deviation. We know that extremes of all our deviation increase pressure on the median nerve inside the wrist, and this can increase the risks of developing problems such as carpal tunnel syndrome. The original alternative keyboard designs split the keyboard laterally to allow people to type with the hands straight rather than bend to the side. A second problem with the design of the conventional computer keyboard is that the hands of in full pronation when typing on the keys. There is a suspicion that working with the hands fully pronated increases the risk of developing musculoskeletal injuries in the forearms. Consequently, alternative keyboard designs have been developed that allow the keyboard slant to be a
