Active range-of-motion (AROM) exercises differ from passive ROM in that:
Explanation
AROM: resident performs the movements independently, maintaining strength, flexibility, and joint health. PROM: CNA moves the joint when the resident cannot. AAROM (active-assistive) is a middle option. The benefits include prevention of contractures, maintenance of circulation, and preservation of function. Distractors (b, c, d) misdescribe the concept; AROM is everyday activity-based or scheduled, not requiring physicians or lifts.
