The classification rules of the International Federation for Wheelchair Fencing state that athletes with a physical impairment that affects at least one leg or foot are eligible to compete in the sport at the Paralympics.
Classification also groups athletes in classes, defined by the degree to which they are limited in their ability to perform activities within that sport. In Wheelchair Fencing there are two classes: Category A and Category B.
Category A athletes have good trunk control and their fencing arm is not affected by their impairment.
Category B athletes have an impairment that affects either their trunk or their fencing arm.
