What is the purpose of passive range of motion exercises?

The correct answer focuses on the role of passive range of motion exercises in preventing contractures, which are the tightening of muscles, tendons, or other tissues that can restrict movement. In patients who are paralyzed or who have limited mobility, regular passive range of motion exercises help maintain flexibility and joint function by moving the limbs through their full range, even when the patient cannot do so actively. This is crucial in preventing the development of contractures, which can lead to complications such as pain, deformity, and loss of function.

While strengthening muscles, increasing endurance, or improving circulation are important aspects of overall patient care, they are not the primary goals of passive range of motion exercises. These exercises are specifically designed for individuals who cannot perform movements on their own, ensuring that their joints remain functional and reducing the risk of long-term complications associated with immobility. Thus, the emphasis is on maintaining joint health and preventing contractures in those who are unable to move independently.
