In the context of motion, what is the opposite of active range of motion?

The correct answer, referring to the opposite of active range of motion, is passive range of motion. Active range of motion involves the voluntary movement of a joint by the individual's own muscle contractions. This means the person is actively engaging their muscles to move a limb or joint, demonstrating both strength and control.

In contrast, passive range of motion occurs when an external force, such as a therapist or equipment, moves the joint without any effort from the individual. This type of motion is essential for assessing the flexibility of a joint, maintaining joint mobility, and evaluating potential restrictions or limitations. Passive range of motion can be particularly useful in rehabilitation and physical therapy settings to help restore movement in patients who may have suffered injuries or experienced immobilization.

Understanding this distinction is crucial for healthcare professionals as it informs assessment and treatment strategies aimed at enhancing a patient's functional mobility and overall musculoskeletal health.
