Following injury or surgery to a specific area, your ability to move an extremity/extremities may be decreased. Depending on your needs assessed by your Physical Therapist Passive Range of Motion (PROM), Active Assistive Range of Motion (AAROM), and/or Active Range of Motion (AROM) techniques will be implemented into your treatment program. Passive Range of Motion is performed by your Physical Therapist without any assistance or effort from you. Active Assistive Range of Motion requires some effort from you to move the affected extremity through the available range of motion either with the assistance of your Physical Therapist or with exercise equipment. Active Range of Motion is performed independently by you, without any external assistance, in which an extremity is moved through the available range.
