What is the term for the stretching or tearing of a muscle or tendon?

The term for the stretching or tearing of a muscle or tendon is referred to as a strain. A strain occurs when the fibers of the muscle or tendon are overstretched or subjected to excessive force, leading to injury. This can happen during physical activities, especially if proper techniques are not used or if the muscles are fatigued.

A strain typically manifests through symptoms such as pain, swelling, limited range of motion, and potentially muscle spasms depending on the severity of the injury. It distinguishes itself from other injuries, such as a sprain—which involves ligaments rather than muscles or tendons—dislocations, which involve the abnormal separation of a joint, and fractures that refer specifically to breaks in bones. Understanding these distinctions is key in the assessment and management of musculoskeletal injuries.
