Continuous intrathecal baclofen therapy in children with cerebral palsy - when does improvement emerge?

Aim: The aim of the study was to explore the timing of effects of intrathecal baclofen therapy in children with cerebral palsy. Methods: Thirty five children with severe disabilities with cerebral palsy who started continuous intrathecal baclofen therapy (CITB) were followed for 18 months. Pain, number of awakenings during night, spasticity, GMFM-66 scores and PEDI scores were recorded the day before pump implantation and after 6 and 18 months of treatment respectively. Results: Introduction of CITB was associated with changes across all ICF dimensions. Reduced pain and improved sleep occurred within 6 months of treatment. Social function improved within 6 months and continued to improve until 18 months of CITB. Mobility also improved, but with a latency. Conclusion: There seems to be a sequence of changes after introduction of continuous intrathecal baclofen in a child with cerebral palsy that may guide the multidisciplinary team in their timing of therapy during post-surgical follow-up.
