Overuse strain injuries are injuries that occur from repetitive movements or putting excessive stress on a particular area of the body. These injuries often result from activities such as playing sports, typing for extended periods, or lifting heavy objects. Synonyms for overuse strain injuries include repetitive strain injuries (RSI), cumulative trauma disorders (CTDs), and musculoskeletal disorders (MSDs). These injuries can be chronic and debilitating, affecting a person's ability to work and perform everyday activities. Preventative measures such as ergonomic adjustments, stretching, and rest breaks can help reduce the incidence of overuse strain injuries and improve overall health and wellbeing.
