Intrathecal Baclofen and Pediatric Dystonia

The goal of this clinical trial is to better understand the effects of intrathecal baclofen (ITB) on children with dystonic cerebral palsy (CP).

The main questions this study aims to answer are:

(1) Determine if ITB reduces dystonia while identifying other potential benefits, (2) Identify the characteristics of children with the best response to ITB (3) Develop a holistically representative composite outcome measure for dystonic CP.

This study will evaluate patient improvement by using a standardized titration, or medication management, protocol to gradually increase the childs ITB dosages over a 12-month period until they achieve maximum benefit with minimal to no side effects. This titration protocol mimics what is currently done through routine care but with more precision. This study will also directly measure the global effects of ITB, taking into account spasticity, known dystonia triggers (e.g. pain), and patterns of CNS injury that cause dystonia.

Participants will:

1. Complete a total of 4 additional clinic visits outside usual care. These appointments will be with physical and occupational therapists as well as the study PI to complete evaluations for dystonia, spasticity, and function. 2. Complete several questionnaires at these visits. The total duration of the study for an individual child will be 12 months.
