Tips on Mouse Use:

  • Mouse height should be level with your elbow and forearm. There should be a 90-degree angle at the elbow with no reaching forward to the mouse. Keep your mouse as close to keyboard as possible.
  • Elbows should be close to body.
  • Wrists should be straight.

  • Use the right size mouse. Mouse should comfortably fit in the palm of your hand without reaching or crunching up the hand/fingers.
  • There are several different types of mousing solutions. For example, Vertical Mice allows individuals to keep their hand in a more neutral posture while moving the mouse from the shoulder. Trackballs utilizes larger muscle groups and a Rollerbar mouse requires less reaching if you have shoulder issues.
