Shoulder Problems

Shoulder problems can greatly affect a person's ability to use standard computer input and output devices. This is especially true of devices such as the mouse that require shoulder movement in order to move the mouse.

Shoulder problems usually include:

• Pain and discomfort in the shoulder.
• Limited range of motion (the shoulder is limited in its movement, usually by pain).
• Pain radiating from the shoulder down the arm or up into the neck.

Another common cause of elbow discomfort is how the elbows are held while keyboarding. In many cases the elbows are held out away from the body in a posture that is known as "winging".

Winging is the posture whereby the albows are held away from the body while typing. This posture can place stress on the elbows, shoulders and neck.
