Abstract：Abnormal walking posture caused by cerebral palsy is the main cause of poor quality of life in children. Orthodic insoles can effectively improve the biological force line and balance ability of lower limbs and feet when children walk，and plantar point therapy is also one of the important means for abnormal sensory input and poor posture control in the Chinese medicine rehabilitation of children with cerebral palsy，so how to combine them is the main problem to be solved at present. The 3D printing technology is expected to realize the unification of the two due to its accurate production function and individualized production，which can significantly improve the walking posture of children and their quality of life.
