Abstract
The rehabilitation engineers of the Kanagawa Rehabilitation. Center have been participating in the rehabilitation team, only when. the rehabilitation engineering process is necessary for solution of the user needs. In many cases, rehabilitation engineers have developed some products, or remodeled the ready-made products, to solve the special needs of a certain user. Since some of the products for such a certain user needs also could solve the needs of many other users, we have been able to develop some bf the wide use products. Out of these products, this time, we report the development of special wheelchair and seating system.
