What are your complaints?
Traditional mouse (flat) and keyboard (too wide) design can encourage you to assume a number of physically awkward postures and to maintain them for long periods of time. Chief among these are:
Effective ergonomic mice and keyboards such as the SRM (Stress Relieving Mouse) and Kinesis Freestyle keyboards are designed to reduce or completely eliminate these ergonomic risk factors.
Ulnar deviation occurs when your wrist is bent outward in the direction of your little finger. On traditional keyboards the span of your shoulders exceeds the contiguous width of the home row of keys. In order to position your hands over the home row it is necessary to bring your hands together in front of your body with your wrists deviated. This constricts the blood flow through your wrist and also requires sustained muscle tension which further reduces blood flow to the muscles. The median nerve runs through the carpal tunnel in your wrist, ulnar deviation reduces the size of this tunnel and pressure on this nerve. Ulnar deviation is among the most common and potentially damaging keyboard postures.
The Freestyle2 keyboard addresses the issue of ulnar deviation in either of two ways: (1) unlimited splay - when connected together the keying modules offer unlimited splay greatly reducing ulnar deviation by placing your wrists in a more neutral position; and (2) complete separation - by removing the Pivot Tether the Freestyle's left and right key modules can be completely separated offering up to 9 inches of separation (20 inch version also available) accommodating a wide-range of shoulder widths while at the same time promoting neutral wrist posture.
