Mobility is the ability to move freely and easily. It refers to a person’s overall capacity to change positions, transfer between surfaces, and ambulate, which reflects functional independence and safety in daily tasks. The term focuses on what a person can do, not just the act of moving or the body parts involved. That’s why it’s the best fit.

The other options don’t capture the full idea: moving describes the action itself, not the ability; musculoskeletal relates to the body systems that enable movement rather than the person’s capacity to move; mouth care has no relation to movement.
