Computer and video games had led to and onslaught of injuries known a Repetitive Stress Injuries (RSI). Repetitive stress injuries (RSIs) are a group of injuries that happen when too much stress is placed on a part of the body, resulting in inflammation (pain and swelling), muscle strain, or tissue damage. This stress generally occurs from repeating the same movements over and over again. One form of these injuries is known as "Nintendo Thumb" or "Nintenditis." Hand and arm problems associated with repetitive tasks first appeared in world medical literature in the 17th century with reports of "milkmaids' arm." In the United States, blue-collar workers reported the first cases of RSI in 1912, when telegraph operators developed a mysterious ailment known as "telegraphists' cramp." Other workers reported such diseases as "washerwoman's thumb" and "glass arm," the latter a painful condition afflicting Morse Code operators during World War I. Assembly line workers, seamstresses, meat packers, and construction workers were later diagnosed with repetitive motion injuries as well. In teens, overuse injuries most often occur at growth plates (areas at the ends of bones where bone cells multiply rapidly, making bones longer as someone grows). Symptoms of RSIs include: 1. Tingling, numbness, or pain in the affected area. 2. Stiffness or soreness in the neck or back most of the time. 3. Feelings of weakness or fatigue in the hands or arms that doesn't seem to get better with rest. 4. Frequent headaches. If you notice any of these warning signs of RSIs, make an appointment to see your doctor. Even if your symptoms seem to come and go, don't ignore them or they may lead to more serious problems. Without treatment, RSIs can become more severe and prevent you from doing simple everyday tasks and participating in sports, music, and other favorite activities. If you are diagnosed with an RSI, resting the affected area is the key to getting better. Your doctor may recommend that you take anti-inflammatory medication (such as ibuprofen) for a period of time. Moist heat treatments are sometimes recommended to reduce pain and swelling.
