What is a strain?

A strain is defined as an injury to a muscle or tendon that occurs due to overstretching or excessive force applied to the muscle fibers. This type of injury often leads to pain, swelling, and limited movement in the affected area. It typically arises from activities that involve sudden movements or overexertion, making it essential to understand the mechanics of muscle function to prevent such injuries.

Understanding this concept is crucial for proper first aid care. By recognizing a strain, a first responder can implement appropriate treatments, such as rest, ice application, compression, and elevation of the injured area to reduce swelling and promote healing. Recognizing the specific nature of a strain allows for better management of the injury and helps prevent further damage.
