What is the term for the full range of movement of a muscle or joint?

The term that describes the full range of movement of a muscle or joint is "Range of Motion (ROM)." This concept is crucial in the fields of health science, physical therapy, and fitness as it refers to the extent to which a joint can move in various directions. ROM can vary between different individuals and can be influenced by factors such as age, physical activity level, and the presence of injuries.

Understanding ROM is vital for assessing joint health, improving physical performance, and designing appropriate rehabilitation programs. It helps in determining how much movement is available to a joint and can guide practices to enhance flexibility and strength while helping avoid injury.

Flexibility often relates to the ability of muscles and tendons to stretch, while mobility encompasses the overall ability to move freely, which also includes strength and coordination. Extension specifically refers to the straightening movement around a joint, but does not cover the complete scope of joint movement. Therefore, "Range of Motion" is the most precise term that represents the entirety of a joint's movement capabilities.
