Which type of range of motion is achieved by an examiner moving the patient's body?

The correct choice is passive range of motion, which specifically refers to the movement of a joint through its available range by an external force, such as an examiner. In this scenario, the examiner actively moves the patient's body segment without the patient's involvement in the movement. This is different from the patient's own ability to move their limb or body segment, which constitutes active range of motion.

Passive range of motion is essential in assessing joint function and can help identify restrictions, pain, or mechanical issues within the joint or surrounding tissues. It is often used in physical examinations and rehabilitation to evaluate the extent of motion possible when the muscles around a joint are relaxed and not engaged in the movement process.

In contrast, active range of motion involves the patient's muscular effort to create movement, while assisted motion implies partial patient involvement or assistance during the movement. Voluntary motion denotes any movement initiated by the individual's own will, further distinguishing it from the passive range facilitated by an external examiner.
