It's only since office work and computers have become such a prominent part of everyday life that these have fallen under the spotlight. This is because it takes time for the repetitive damage to reach a level where it causes problems. As time passes and the damage continues, symptoms occur whilst performing the repeated activity, when typing for example. As the situation becomes more severe, pain may be felt most of the time, even with the slightest movement. One or both upper limbs may be affected, depending on which is being used to perform the repetitive activity causing the problem.
Many people find they also experience numbness and tingling.
Sometimes, this and the pain mean that they find it difficult to hold objects, and often drop them. Beware of RSI Someone is at risk of suffering with RSI if their job involves performing repetitive movement over and over again. This risk is increased if they spend long periods of time, sitting on an uncomfortable seat, or at a poorly arranged workstation without taking a break. Prevention is always better than a cure, which is why it's important to ask your employer to assess and make sure that your workstation and seating position are correct. It's amazing how a simple adaptation, such as using a foam support to rest the wrists on when typing, can make all the difference.
