What does passive range of motion (PROM) refer to in physical therapy?

Passive range of motion (PROM) refers to the type of movement that is performed on a patient's joint or limb by an external force, typically a therapist, without any effort or assistance from the patient. This is done to maintain flexibility, prevent stiffness, and promote circulation in the affected areas.

In the context of physical therapy, the therapist typically moves the patient's limb through its full range of motion to ensure that the joint is not restricted and to prevent complications associated with immobility. The patient does not engage in this movement actively; rather, they remain relaxed while the therapist performs the movements on their behalf.

Understanding PROM is crucial for therapists, as it helps them assess the limits of a client's range of motion and determine any potential issues that may need addressing through further treatment or exercises.
