Which term describes a barrier that is a functional limit that diminishes normal physiological ROM?

• A. Elastic Barrier
• B. End Feel
• C. Functional Barrier
• D. Restrictive Barrier

Answer: (D)

In ROM assessment, barriers are the limits you encounter as you move. The elastic barrier comes from the tissues stretching elastically—it's the first resistance you feel, but it doesn’t define a true end to motion. End feel is the quality of resistance you sense at the end of the range, not a barrier itself. The term that describes a functional limit that diminishes normal physiological ROM is the restrictive barrier. This barrier represents a functional constraint, such as soft-tissue tension or neuromuscular guarding, that reduces the usable range without requiring a fixed structural block. It’s the functional limitation of motion rather than anatomic blockage, and it can often be addressed through techniques that reduce the functional constraint.
