If you perform the same task over and over throughout the course of the day, using the same muscles, tendons, and ligaments; you are at risk for injury due to repetitive motion. Human bodies are not meant to perform tasks without variety in movement. Soft tissues such as muscles, nerves, and connective tissue become fatigued and blood supply is restricted when there is repetitive motion. To assess whether your movements are repetitive at work, keep a log of your tasks throughout the day. For example, if you start typing a report, make a note of what time you started and when you finished. Make a note of any rest breaks or other diversions, e.g. a phone call. If you type more than one hour without a break, you are placing yourself at risk for injury due to repetition. Try to make sure you break up your tasks during the day with other non-similar tasks or with 1-2 minute rest breaks. You should actually find yourself being more productive and less fatigued when you give your body time to repair and rejuvenate.
