Active Range of Motion, commonly called AROM, refers to movement of a joint through its complete plane of motion entirely by the patient's own muscular contraction. No outside force or assistance from the nurse or therapist is applied during the movement. This form of exercise tests the functional capacity of the musculoskeletal system and serves as a baseline for physical assessment.
Regular performance of AROM preserves joint mobility and prevents the stiffness that naturally occurs with prolonged bed rest. When muscles contract to move the bones, they act as a natural pump on deep veins, which significantly enhances venous return and lowers the risk of deep vein thrombosis. Furthermore, active movement maintains muscle tone, preserves cardiac output through mild exertion, and supports psychological well-being by fostering patient autonomy during recovery.
AROM is indicated for clients who have adequate muscle strength and are conscious enough to follow instructions, especially those recovering from prolonged immobility, mild strokes, or non-weight-bearing orthopedic injuries.
However, nurses must withhold these exercises when certain risks are present. Contraindications include recent unhealed fractures, severe soft tissue trauma, acute joint inflammation or infection, and direct orders from the physician for strict bed rest or zero movement to protect a surgical site.
Before starting exercises, assess the patient's baseline vital signs, current pain score, level of fatigue, and cognitive capability to follow commands. Explain the routine clearly using simple language suited to the patient's understanding. Ensure the room has adequate privacy, adjust the bed height to a comfortable working level to protect your own back, and remove any restrictive clothing or bed covers that might block joint movement.
Monitor the patient continuously for signs of physical distress during movement. Watch for sudden shortness of breath, pale or flushed skin, diaphoresis, or facial grimacing. Never force a joint past the point of resistance or into a range that causes acute pain. If the client experiences dizziness, weakness, or sharp discomfort, stop the session immediately, assist them to a safe resting position, and notify the supervising nurse or doctor.
Record the completed exercise session in the patient's nursing notes promptly. Document the specific joints exercised, the number of repetitions, the patient's tolerance level, and any complaints of pain or fatigue. Note objective findings such as improved joint angle or persistent stiffness. Clear documentation ensures continuity of care and allows the interprofessional healthcare team to track functional progress over time.
