The use of tiagabine in pediatric spasticity management.
Tiagabine, developed as an anti-epileptic medication, has the potential to reduce spasticity. The purpose of the present study was to assess the effectiveness of tiagabine in decreasing spasticity and improving the functional abilities of children with spastic cerebral palsy (CP). Nine children (seven females, two males) with CP (six spastic quadriplegia, three moderate to severe spastic diplegia) were treated with tiagabine for a mean of 7.2 months. Median age was 4y 5mo (range 3y 2mo-10y). All children were non-ambulatory. According to the Gross Motor Function Classification System, six were Level IV and three were Level V. Only one child showed a median decrease >or=1.0 grade on the modified Ashworth scale in upper extremities, lower extremities, and overall. Another child had significant improvement in the Pediatric Evaluation of Disability Inventory Self-care score and improved feeding. None of the participants was found to have a significant improvement in motor function or a decrease in the number of motions (passive range of motion and muscle length test) that were limited. Reduction of nocturnal awakenings from painful spasms was reported in one child. Eight of the nine children experienced adverse side-effects during treatment. Although tiagabine was not found to be effective in decreasing children's spasticity or improving their function, its potential use in the relief of painful spasms associated with neurological conditions in the pediatric population warrants further investigation.
