What is meant by range of motion (ROM)?

Range of motion (ROM) refers to the full movement potential of a joint, encompassing the various angles and directions in which that joint can move. This concept is crucial in understanding joint health and function, as well as in designing effective rehabilitation and exercise programs. A larger range of motion is generally associated with better flexibility and mobility, which can improve athletic performance and decrease the risk of injury.

This definition considers the capabilities of the joint itself rather than external factors like muscle strength, speed of exercise, or overall muscle flexibility. While flexibility can influence range of motion, ROM specifically focuses on the joint's movement capability, making it a fundamental aspect of kinesiology and physical therapy practice. Understanding ROM is essential for kinesiotherapists, as they aim to enhance joint function and improve patients' overall physical performance.
