Quantity ROM is assessed from which ROM measurements?

• A. Passive ROM only
• B. Active and passive ROM
• C. Active ROM only
• D. End Feel

Answer: (B)

Quantity ROM is determined by both what a patient can actively move and what is available when the joint is moved passively. Active ROM shows the movement the patient can perform with their own muscles, reflecting strength and control, while passive ROM shows the available movement when the examiner moves the joint without the patient’s muscle effort, reflecting flexibility and tissue length. Using both measurements gives the complete picture of how much motion the joint truly has and helps distinguish limitations due to muscle weakness, pain, or mechanical restrictions. End feel, on the other hand, describes the quality of the resistance at the end of range, not how much range there is, so it doesn’t quantify ROM.
