What is the definition of range of motion (ROM)?

Range of motion (ROM) refers specifically to the extent of movement that a joint can achieve without experiencing pain. It encompasses the full movement potential of a joint, typically measured in degrees of a circle. This definition is crucial in fields such as physical therapy, rehabilitation, and athletic training, as it helps professionals assess joint function, diagnose potential issues, and develop treatment plans tailored to individual needs.

The importance of ROM lies in its ability to indicate the flexibility and health of joints. When a joint has a full range of motion, it allows for optimal movement and function, which can help prevent injuries and maintain overall physical well-being. Pain-free movement is a key aspect, as any limitation in ROM often signals underlying conditions or injuries that warrant further investigation or intervention.

Understanding and measuring ROM is essential for monitoring progress in rehabilitative settings, ensuring that patients regain functional mobility and strength after an injury or surgery. In contrast, the other options focus on different aspects of movement and bodily function, which do not encapsulate the precise definition of range of motion.
