Let’s talk about the keyboard.
I’ve probably used a couple dozen different keyboards over my lifetime. Some are great; others are horrible. Currently I’m using the Logitech Ergo K860 wireless keyboard (see photo above) and find that it fits my needs nicely.
What factors should you consider when purchasing and using a keyboard? Below are a few suggestions:
Maintain neutral wrist position: You want a keyboard that will allow neutral wrist positioning during use. Specifically, you want to minimize ulnar deviation (wrist bent toward the little finger), extension (back of hand raised toward the elbow), and flexion (palm bent towards the wrist). The best way to minimize ulnar deviation is to use a split keyboard. Unnecessary extension and flexion are controlled by keyboard placement (see below for details).
Locate close to the body: Place the keyboard close to the body to prevent having to reach when typing. If located too far from the body this can result in unnecessary tension in the upper arms and shoulders.
Position at elbow height: Placing the keyboard at elbow high will minimize unnecessary extension or flexion. If you use a keyboard tray, make sure it’s not adjusted too low forcing the wrist into extension.
Minimize laptop keyboard use: Laptops are wonderful for allowing a person to take their work with them. But, ergonomically speaking, they’re a train wreck! The narrow keyboard almost guarantees ulnar deviation during use. Also, placing them on your lap to work typically introduces unnecessary wrist extension. My best suggestion is to use an external keyboard whenever possible.
Relaxed arm position during use: Some people have a tendency to tense up when typing. This often is due to a poorly designed and placed keyboard. Following the four recommendations provide above will definitely help maintaining relaxation to allow for typing without unnecessary fatigue.
