Active Range of Motion (AROM)
Active Range of Motion (AROM) refers to the movement of a joint performed entirely by the individual’s own muscle contraction without external assistance. During Active Range of Motion, the person voluntarily moves the joint through its available range while the physiotherapist observes the quality, extent, and control of movement. AROM provides valuable information about muscle function, joint mobility, pain, and neuromuscular control.
Clinical Importance
Active Range of Motion helps clinicians assess whether a patient can move a joint independently and effectively. Limitations in AROM may indicate muscle weakness, pain, joint stiffness, neurological impairment, or tissue injury. Therefore, AROM assessment plays an important role in diagnosing movement dysfunction and monitoring rehabilitation progress over time.
Physiotherapy Relevance
Physiotherapists frequently use Active Range of Motion during musculoskeletal, neurological, and postoperative assessments. AROM exercises help maintain joint mobility, improve muscle strength, enhance circulation, reduce stiffness, and promote functional independence. In addition, regular AROM exercises may prevent complications associated with prolonged immobilization and inactivity.
Everyday Example
When a person lifts their arm overhead, bends the knee, or turns the neck without any assistance, they are performing Active Range of Motion. These movements occur regularly during daily activities such as dressing, walking, reaching, and exercising.

Clinical Pearl
A patient may demonstrate full passive range of motion but limited Active Range of Motion because of muscle weakness, pain, or neurological impairment. Therefore, comparing active and passive movement provides valuable clinical information.
Frequently Asked Questions
What is Active Range of Motion?
Active Range of Motion is the movement of a joint performed independently by the patient using their own muscle strength without external assistance.
What is the difference between AROM and PROM?
In Active Range of Motion, the patient moves the joint independently. In Passive Range of Motion (PROM), an external force such as a physiotherapist or device moves the joint while the patient remains relaxed.
