Therapeutic horseback riding have been believed as a good media to improve balance ability. We proceeded to do a case study, by the use of a mechanical horse made by Joba EU-6441, Matsushita Electric Industrial Co., Ltd., Japan. This mechanical horse is designed according to the movement pattern of a real horse. The seat is designed to move in a pattern based on the figure of eight. Many clinics begin to adopt the mechanical horses as treatment tools, but its effectiveness in children with ADHD remains unknown.
