Which orthosis is indicated for a child with S1 intact from spina bifida?

In the case of a child with S1 intact from spina bifida, the correct choice is indeed the UCBL (University of California Biomechanics Lab) orthosis. This type of orthosis is specifically designed to provide support and alignment for the foot and ankle, which are crucial for children who may have some residual function and power in their lower limbs but require additional stability.

The UCBL is particularly beneficial for managing conditions that affect the gait and biomechanics of children, as it offers both medial-lateral stability and a capture of the heel to facilitate proper foot development and alignment. Given that the child has intact S1 function, which can support some mobility, a UCBL can effectively assist in promoting functional ambulation while addressing issues related to foot positioning and alignment.

Other options, such as HKAFO (hip-knee-ankle-foot orthosis), KAFO (knee-ankle-foot orthosis), and SAFO (solid ankle-foot orthosis), are typically utilized for more complex needs that involve severe weakness or paralysis where more extensive support is necessary. For example, HKAFO is designed for children with significant lower extremity involvement, providing stabilization at the hip as well, and is generally reserved for cases where
