1. Is the monitor slightly below eye-level?

1. Are the keyboard and mouse on the same level?

1. Is the mouse close to the side of the body, so it can be easily reached without extending the forearm sideways?

1. Is your head directly over your shoulders?  (Ears in line with shoulders and not hunched over).

1. Is your back straight and lower back supported by the chair?

1. Are your thighs and arms parallel to the floor?

1. Are your shoulders and arms loose and relaxed?

Is your head straight most of the time and not looking down at the keys? (Touch-typing skills are a big help here!)

1. Are your fingers resting on the mouse between the clicks?  (Make sure the clicking finger it is not being raised between use).

1. Are your fingers relaxing into a rainbow down to the keys when typing?  (No claws or spider legs!)

1. Elbows close to the side of the body, at just slightly more than a 90° angle?

1. Do you know to take regular breaks to stand and stretch?

1. You also need plenty of aerobic exercise -- it's highly protective against overuse injury.

1. Breathing from the abdomen can help too - not short chest breaths but belly breaths that get oxygen into the blood and out to muscles.

1. Are you able to touch type?  This can help prevent overuse injury.

1. Have you received training in the program you are using?  This training will reduce the frustration of learning by trial and error.

1. Do you know the keyboard shortcuts?  Using keyboard shortcuts will cut down mouse use and help prevent mouse injury.
