Rhizotomies often permanently relieve spasti-city in the legs.
Rhizotomies are most often performed in children four-to-eight years old with moderately severe or severe spasticity that affects the legs more than the arms, who have reasonably good leg strength and are usually able to waLk to some extent with or without assistive devices, who have not yet developed multiple contractures in the legs.
Rhizotomies are also appropriate in severely delayed children with spastic quadriplegia that affects the legs more than the arms, for whom the goal is to facilitate their care, not to improve their function.
