Repetitive Motion Injuries
Repetitive Motion Injuries (RMI, also known as RSI, CTD, CTS) are a class of injuries and illnesses that result from weeks, months or years of overuse of human joints. Connective tissues can become sore and sometimes unusable from repeated exposure to micro-trauma. Because of the slow onset of symptoms, people sometimes ignore the condition until the symptoms become chronic and permanent injury occurs.
The best way to visualize RMI is to think of each of your joints as a bucket. Micro-trauma from a variety of activities drips into your joints trauma bucket. Fortunately, your body can heal with time and safely absorb a certain amount of trauma. But if more trauma is placed into the bucket than can be absorbed by the natural healing process, the result can be pain and impaired movement.
RMI is a disorder that is based upon the time, amount and severity of your exposure. RMI disorders occur gradually over a long period of exposure to low level harmful conditions. A brief exposure to these conditions would not cause harm. But a prolonged exposure may, in some people, result in reduced ability to function.
Not all pain will result in long-term disability. Muscle pain often develops after exerting yourself in ways that the body is not accustomed. Luckily, muscles heal very quickly, and even extreme muscle pain will usually diminish within a few days when managed properly.
