SPASTICITY IN CHILDREN WITH CEREBRAL PALSY: A RETROSPECTIVE REVIEW OF THE EFFECTS OF INTRATHECAL BACLOFEN

The administration of baclofen by intrathecal pump is a new technique used to reduce spasticity for individuals with upper motor neuron system injuries. Children with cerebral palsy often have difficulty in mobility because of this form of spasticity. The purpose of this study was to assess the functional outcomes of intrathecal baclofen pump therapy with spasticity in children with cerebral palsy. A retrospective review of medical records for pediatric cerebral palsy patients receiving intrathecal baclofen for intractable spasticity was performed. Of 23 sequential medical records meeting requirements for inclusion in the study, 17 subjects had sufficient recorded data to be included in the study. Data from the medical records included Ashworth scores, therapy complications, and changes in mobility and independence. Although no significant changes in the upper extremities with intrathecal baclofen occurred at one and three months, the trial bolus showed statistically significant changes in mean Ashworth scores. The pre- and posttrial bolus Ashworth scores for the lower extremities showed statistically significant decreases in the posttrial scores and at one and three months when compared with the pretrial scores (p < .001). Complications were resolved with conservative management without long-term sequelae. No infections, respiratory depressions, or deaths occurred as a result of intrathecal baclofen therapy in this study. Although intrathecal baclofen had a significant effect in reducing lower extremity spasticity in children with cerebral palsy, further prospective studies are needed to determine the effects of intrathecal baclofen on such indicators as activities of daily living.
