What causes RSI? RSI is caused by any demanding activity that exceeds the ability of the body to do work. Common factors that are associated with RSI include too many uninterrupted repetitions of an activity or motion, performing an activity in an awkward or unnatural posture, maintaining static posture for prolonged periods, failing to take frequent short breaks, and stress. Also, certain medical conditions such as rheumatoid arthritis and diabetes may contribute to RSI. What should I do if I start to experience RSI symptoms or discomfort? By following the guidance on proper equipment and work environment set up and use, the risk of developing RSI can be minimized. However, if you are experiencing any discomfort, seek professional medical advice immediately. Typically, the earlier a problem is diagnosed and treated, the easier it may be to resolve.
