What is the main purpose of ROM and PROM exercises?

• A. Prevention of contracture development
• B. Increase bone density
• C. Improve endurance
• D. Enhance cardiovascular fitness

Answer: (A)

Preserving joint mobility and preventing contractures is the main goal of ROM and PROM exercises. When movement is limited, soft tissues can shorten and scar tissue can form, leading to stiffness and reduced range of motion. Moving the joint through its available range helps maintain tissue length, supports lubrication of the joint, and promotes circulation, all of which keep the joint flexible. PROM is done by another person or a device when the patient can’t move the joint, while ROM can be performed actively by the patient or with assistance. These techniques focus on joint flexibility and tissue health, rather than increasing bone density, endurance, or cardiovascular fitness, which require weight-bearing, resistance, or aerobic activities.
