Which statement supports preserving range of motion of the unaffected joints when designing a splint?

• A. Include all joints to maximize stabilization.
• B. The splint should be colored for visibility.
• C. Avoid restricting ROM of non-affected joints.
• D. The straps should be snug with no padding.

Answer: (C)

Preserving motion in joints that aren’t injured helps prevent stiffness and preserves overall hand function during healing. When a splint is designed, the goal is to immobilize only what’s necessary to protect the injured tissue while keeping adjacent joints free to move. This targeted immobilization supports tendon glide, reduces the risk of contractures, and helps the patient regain function more quickly.

That’s why avoiding restrictions on the range of motion of non-affected joints is the best approach. Including all joints would unnecessarily limit movement in joints that don’t need immobilization, harming function. Color doesn’t affect ROM, and a strap that’s snug with no padding can cause discomfort or skin problems, which can indirectly impede movement.
