Which term describes the ability to perform tasks like stepping, reaching overhead, or clearing a step?

• A. Normal ROM
• B. Functional movement capacity
• C. Arthritis impairment
• D. Hypermobility

Answer: (B)

The ability to perform tasks like stepping, reaching overhead, or clearing a step is about functional movement capacity—the integrated ability to use mobility, strength, balance, coordination, and motor control to carry out real-world movements.

This goes beyond just how much a joint can move. Normal range of motion measures how much movement is available, but it doesn’t tell you how well someone can use that movement during tasks. Arthritis impairment describes a disease or condition affecting joints, not the overall capability to perform everyday movements. Hypermobility refers to excessive joint movement, which can cause instability but doesn’t by itself describe how effectively someone can execute common tasks. Functional movement capacity best captures how people actually move in daily life.
