What describes a patient's ability to complete motion unassisted?

Active Range of Motion (AROM) describes a patient's ability to complete motion unassisted. This term refers to the movement that a patient can achieve independently, using their own muscle strength without assistance or support. AROM is a critical aspect of physical therapy as it demonstrates a patient’s level of strength and control over their joints and muscles.

In contrast, passive range of motion (PRM) involves movement that is performed by an external force, such as a therapist or another person, without the patient's own muscle effort. Isometric refers to a type of muscle contraction where the muscle length does not change while contracting; this is not related to the ability to move a joint. Transfer motion involves the ability to move from one position to another, such as from sitting to standing, which does not specifically capture the concept of completing motion unassisted. Therefore, AROM is the correct term that encapsulates this ability.
