The purpose of this study was to analyze sports injuries in athletes with disabilities during the 2015 National Games in Korea. We conducted a survey to assess sport injuries in 171 male athletes with disabilities who participated in this study. The shoulder was most frequently injured, followed by the fingers and low back. Contusions were the most common type of injury, and were usually caused by collisions with teammates or contact with equipment. Injuries often occur during enthusiastic play in both competition and practice sessions. Injured athletes are emergently treated with medicated spray and patch application by the head coach. Warm-up and cool-down exercises are recommended to prevent injury, and physical therapy is effective after an injury occurs. Based on these findings, an injury prevention training program and athletic trainers should be provided for athletes with disabilities to ensure appropriate care and rehabilitation.
