Functional Barrier is defined as?

• A. A barrier that limits passive ROM
• B. A factor that restricts or limits motion
• C. The range between barriers
• D. Increased muscle tone

Answer: (B)

Functional barrier refers to non-structural limits to movement—that is, factors that restrict or limit motion due to function rather than tissue end-points. This includes things like pain, reflex guarding, muscle tone, or fear that cause the body to stop moving before the anatomical end of motion is reached. That’s why it’s best described as a factor that restricts or limits motion. The other ideas fit more with structural limits, the overall range of motion, or a specific cause like muscle tone, rather than the broad concept of a functional barrier.
