What does passive range of motion exercise prevent?

Passive range of motion (PROM) exercises are primarily designed to maintain flexibility and mobility in a joint without the individual actively contracting the surrounding muscles. By doing so, these exercises effectively help prevent joint stiffness.

When an individual is unable to move a joint through its range, either due to injury, surgery, or other conditions, PROM exercises ensure that the joint is still subject to movement. This is important because immobilization can lead to adhesions and increased stiffness in surrounding structures, limiting the function of the joint. Regular PROM exercises can therefore help preserve the normal range of motion and prevent complications associated with joint stiffness, aiding in the healing process and improving overall mobility.

Other options, while related to musculoskeletal health, are either not directly impacted by PROM exercises or pertain to different aspects of physical health and rehabilitation.
