Para-equestrian
Para-equestrian is an equestrian sport governed by the International Federation for Equestrian Sports (FEI), and includes two competitive events: One is para-equestrian dressage, which is conducted under the same basic rules as conventional dressage, but with riders divided into different competition grades based on their functional abilities. The other is para-equestrian driving, which operates under the same basic rules as combined driving but places competitors in various grades based on their functional abilities.
