After examining thousands of children with cerebral palsy, I found that many of them (spastic cerebral palsy) have high muscle tone and long-term spasticity that can cause obvious short and long feet. Some children with cerebral palsy are older and have more mature skeletal development than younger children. Before the spasticity is lifted, the spasticity (such as tiptoeing) can affect skeletal development and the FSPR procedure described in my last article was performed. Here I would like to give you a suggestion, to make a heel enhancement insole (such as 3D printing insole) for the shorter foot of the child, so that both lower extremities keep the same length, the child is growing, the bones are also developing, the family should gradually thin the insole, and finally remove the insole, the younger children have more space for bone development than the older ones, so the family needs to consider the prognosis of its effect.
