Reduce keystrokes with the use of macros or software programs allowing "sticky keys." Use scroll locks and keystroke combinations to reduce pointing-device movements.
Alternate tasks to make changes in your working position to avoid making the same movements for prolonged periods of time.
Keep your fingers and knuckles relaxed when working at the keyboard.
Never hold a pen or pencil in your hand when keying.
Avoid hitting the keyboard with excessive force. Studies have shown that the average user hits the keyboard with four times the required force when keying.
Avoid holding your pointing device tightly. Your hand should be relaxed.
Rest your eyes by refocusing on distant objects intermittently when working.
