If you’ve spent hours and hours using a keyboard without relief, you know just how much strain it can place on your hands, wrists, and upper body. Most traditional keyboards have their design with little thought to ergonomics. That has changed with the arrival of alternative ergonomic keyboards.
These alternative ergonomic keyboards have been designed not only for functionality but also to help maintain the upper body including the arms, wrists, and hands in a neutral position. This neutral position reduces stress and strain on muscles tendons, and nerves to eliminate possible injury from repetitive stress of using a keyboard. The different designs of the alternative ergonomic keyboards help the user to change their posture to a more neutral and comfortable position. For example, a split keyboard is designed to straighten the wrists by increasing the distance between right and left keyboard sides or by allowing the rotation of each half of the keyboard to position it so it is aligned properly with the forearm. Another keyboard design is the tented keyboard.
A variation of the split keyboard, each half is tiled up thus reducing the rotation of the forearms. Still another type of keyboard design allows the user to raise the front edge of the keyboard. This provides you with a backward slope that straightens the wrist in a more neutral position.
Perhaps one of the most popular alternative ergonomic keyboard designs is that of built in wrist or palm rests. Some researchers question whether these increase the pressure on the wrists or interfere with typing. Still there are those who much prefer a keyboard with wrist rests.
When you try a new keyboard give yourself enough time to adjust to the differences. Once you try it for a few days you’ll know the usefulness of ergonomics on your keyboard.
