What is the main difference between a strain and a sprain?

The key distinction between a strain and a sprain lies in the types of tissues that are affected. A strain specifically refers to an injury to muscles or tendons, which are the tissues responsible for movement and connecting muscles to bones. This type of injury usually occurs when muscles are overstretched or torn, often due to excessive force or improper lifting techniques.

In contrast, a sprain pertains to an injury involving ligaments, which are the connective tissues that link bones at a joint. Sprains often occur when a joint is subjected to excessive force or twisting, leading to stretching or tearing of the ligaments.

Understanding these definitions is crucial for appropriate assessment and treatment of these injuries, ensuring that the right course of action is taken to facilitate recovery.
