Spasticity and movement disorders in cerebral palsy

To review the neurosurgical treatments of children with movement disorders associated with cerebral palsy (CP) during the previous decades, up to the present day.

An extensive literature review was undertaken to identify important publications about this subject. My experience treating children with these disorders over the past three decades was included in the individual sections.

Peripheral neurotomies have been developed for children with focal spasticity. For those with spastic paraparesis, selective lumbar rhizotomies were developed, and for those with spastic quadriparesis, intrathecal baclofen infusions were developed. Both effectively alleviate spasticity in the affected extremities. Generalized dystonia associated with CP has been treated with deep brain stimulation with mild improvement, but treatment with intrathecal baclofen and intraventricular baclofen improve those movements markedly. No effective treatment has been reported for children with athetoid CP. For those with choreiform CP, deep brain stimulation may be effective but intrathecal baclofen does not appear to be.

Treatment of children with movement disorders associated with CP increased slowly in the 1970s and 1980s but accelerated rapidly in the 1990s with the introduction of lumbar dorsal rhizotomies and intrathecal baclofen. In the last 30 years, tens of thousands of children with spasticity and movement disorders associated with CP have been treated by pediatric neurosurgeons, and their care has become an integral component of current pediatric neurosurgical practice.
