This movement, in combination with pad height also helps to get the neutral angle in the wrist extension (as we commented in the ergonomic post Part 2 ), helping to get a comfortable and relaxed neutral position in both hands during typing and resting. In the Shortcut keyboard the palm rest is adjustable and can be moved further or closer to the keyboard, so it can be adapted to different hand sizes, avoiding pressure in the wrong part of your hand. Comfort is similar but pressure in the median nerve is significatively reduced. Instead of a wrist rest, a better solution is the use of palm rests, resting only the lower part of the hand or hand heel. In the case of hardcore computer users, the wrist rest use increases the pressure in the carpal tunnel and can cause some injuries, like Carpal Tunnel Syndrome. The most common solution is the use of a wrist rest, but when you use it the pressure in the wrist can cause a decrease in blood supply to the working muscles and nerves. It is good that the arm has a place to rest during typing, even it is not absolutely necessary, it strongly reduces stress in the hand and shoulder muscles. In this article we focus on the palm rest, and the different points we have taken into consideration during the Shortcut’s design to prevent health problems and increase the user’s comfort.

This is Part 3 of a series on ergonomics (read the Part 1 and Part 2 here) where we explained the different injuries caused by bad positions in keyboard users, and how you can prevent them by using the Shortcut.
