Overall disability sum score = arm disability scale (range 0–5) + leg disability scale (range 0–7); overall range: 0 (no signs of disability) to 12 (maximum disability).
For the arm disability scale: allocate one arm grade only by completing the function checklist. Indicate whether each function is “affected,” “affected but not prevented,” or “prevented.”
For the leg disability scale: Allocate one leg grade only by completing the functional questions.
