Which statement best describes Passive ROM?

Which statement best describes Passive ROM?

• A. Movements initiated by the athlete
• B. Movements performed by the examiner with the athlete relaxed
• C. Movements performed while the athlete stands
• D. Movements measured with instrumented devices

Answer: (B)

Passive ROM is the amount of movement that the joint can achieve when someone else moves it for you while you stay completely relaxed and don’t use your muscles. This isolates the joint and soft-tissue flexibility without any active muscle contraction, helping reveal true tissue length and joint restrictions. The other ideas don’t describe passive ROM: if you initiate the movement yourself, that’s active ROM; standing position or how the motion is measured doesn’t define passive ROM.
