Which measure assesses passive range of motion?

• A. Goniometers
• B. AROM
• C. PROM
• D. Symptom localization

Answer: (C)

Passive range of motion is the amount a joint can move when someone else moves it for the patient while the patient stays relaxed and does not actively contract muscles. This is measured as PROM, since the movement is produced without the patient’s active muscle effort. In contrast, active range of motion involves the patient using their own muscles to move the joint, and a goniometer is the tool used to quantify the angle in either passive or active testing. Symptom localization is about pinpointing where symptoms occur, not about how much the joint moves.
