PROM goals include maintaining joint mobility as a key objective.

• A. Maintain joint mobility
• B. Increase strength
• C. Improve motor control
• D. Balance training

Answer: (A)

Passive range of motion aims to preserve joint mobility when a person cannot move the joint voluntarily. By gently guiding the joint through its available range, the surrounding soft tissues—muscles, tendons, ligaments, and capsule—are kept from shortening and losing elasticity, which helps prevent contractures. This approach also supports the distribution of synovial fluid for joint nutrition and promotes circulation, all of which help maintain the joint’s health and prepare the individual for eventual active movement.

So, maintaining joint mobility is the best fit because PROM focuses on preserving the joint’s range and tissue length when active movement isn’t possible. Increasing strength requires active or resisted movement, improving motor control involves voluntary neuromuscular practice, and balance training centers on postural stability rather than preserving joint range.
