In the context of mobility, how is "range of motion" defined?

"Range of motion" refers specifically to the full movement potential of a joint, which is typically measured in degrees. This concept is crucial in mobility assessments, as it describes how far a joint can be moved in different directions without restriction. Each joint in the body has its own normal range of motion, and evaluating this can help identify issues such as stiffness, pain, or injuries that could limit mobility.

When assessing mobility, understanding a person's range of motion can indicate their overall physical health, flexibility, and functional capacity. For instance, athletes may need a greater range of motion for optimal performance, while older adults may experience a decrease in range associated with aging, which impacts their ability to engage in everyday activities.

Other options present different aspects of physical fitness or mobility but do not accurately describe the specific definition of range of motion.
