Functional characteristics: In the process of crawling, children need to exert their four feet at the same time, which is conducive to the development of children's physical coordination. If the child does not crawl smoothly during the crawling period, when learning to walk in the future, the coordination ability is obviously not as good as that of the child who practices more when crawling. Through constant crawling practice,Children's leg muscles and hand muscles have been well relaxed, which is conducive to children's health, especially children with cerebral palsy with brain injury, whose development is slower than normal children, parents should take it more seriously. Creeper frame can be effective. Train the upper limb support and crawling ability of children with cerebral palsy or developmental retardation, and promote physical coordination, balance and vestibular perception. Main functions of the creeper frame: 1. Improve the support ability and coordination of children's hands; 2. Promote the development of four-point supporting ability; 3. Promote the separation of the body and the limbs and the alternate flexion and extension of the two lower limbs; 4. Promote the development of crawling movement.
