What does a strain refer to?

A strain refers specifically to an injury to a muscle or tendon. This type of injury occurs when the muscle or tendon is stretched or torn, typically due to excessive force or overexertion. Strains can vary in severity from mild overstretching to complete tears, and they often present with symptoms such as pain, swelling, and limited mobility in the affected area.

The terminology is essential in understanding the nature of the injury. While a ligament injury is termed a sprain, a strain is distinctly related to muscles and tendons. Strains are common in activities that require sudden movements or heavy lifting, which further emphasizes the role of muscle and tendon integrity in physical activities.
