Computer users often place their mouse far from the keyboard. This causes an awkward wrist and shoulder posture when operating the mouse. Both the keyboard and the mouse should be at elbow height with the mouse close to the keyboard.
If you are right handed, rarely use your keyboard’s numeric pad, and using a traditional mouse, try a mouse bridge. A mouse bridge is a platform that fits over the numeric pad. This places the mouse directly in front of the right shoulder for maximum comfort. There are different types of mouse bridges to fit your keyboard. These include rear adjustable, side adjustable, and even a flat mouse bridge that fits directly on the keyboard. These work best with a mouse pad.
