Types of CP that are commonly found are Diplegic Cerebral Palsy (DCP) and Hemiplegic Cerebral Palsy (HCP). Percentage of DCP about 30 to 40 percent and HCP about 20 to 30 percent. The physical condition of a DCP has weak hip, so there is no strength to lift the body and physical condition of an HCP has one spastic hand down and swings to exhortation. Rehabilitation for them must be continuing to maximize the walking ability and increase physical mobility. Walker used to improve children's walking. Nowadays, walker is still too heavy, walker dimensions have not considered the size of anthropometry's children, and walkers have not accommodated users. Therefore, a walker was designed based on concept of DCP and HCP using TRIZ method. The aim is choosing design that accommodate the needs of children for supporting rehabilitation. The results of products dimension are maximum height 107.3 cm, minimum height 60.0 cm, length of walker 71.7 cm, length of handgrip 10.4 cm, and diameter of hands pad 3.3 cm.
