Which statement accurately describes mobility assessment components?

• A. Only physician opinion.
• B. Relies on imaging only.
• C. It includes ROM measurements, strength testing, and functional tasks.
• D. It uses only patient self-report.

Answer: (C)

Mobility assessment is built from multiple facets that together reveal how well a person can move and participate in daily life. Measuring range of motion shows the possible movement at joints and flags contractures or stiffness that limit mobility. Testing strength indicates the force the muscles can generate, which influences speed, stability, and the ability to perform tasks like standing, walking, or climbing. Observing and evaluating functional tasks then shows how these capacities translate into real-world performance—walking pattern, balance, transfers, stairs, and overall safety.

Relying only on a physician’s opinion misses the objective data about how the joints function and how the person actually moves. Imaging reveals structural details but not how movement feels or functions in daily activities. Relying only on patient self-report misses objective measurements and may not capture performance limitations or compensations seen during tasks. Combining ROM, strength, and functional task assessments provides a complete, actionable picture to guide goals and therapy planning.
