Is this trial a fit for you?
✓Likely a good fit
Children aged 3 to 14 with cerebral palsy who are planned to undergo selective dorsal rhizotomy.
✕Probably not a fit
Patients whose spasticity is not reduced by the added stimulation or who cannot proceed with SDR as planned may not experience benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
The trial will enroll children with cerebral palsy who are scheduled for selective dorsal rhizotomy. During SDR, researchers will apply higher-frequency dorsal root stimulation alongside the standard clinical test stimulation to see if it reduces the abnormal muscle responses measured by CMAP. The procedure uses a constant current stimulator and the Cadwell Guardian System to deliver stimulation. Outcomes focus on whether the added stimulation can decrease spasticity without altering standard care or insurance coverage. This is a surgical-augmentation approach conducted at a single pediatric center.
Why it matters
Potential benefit: If successful, the approach could reduce spasticity in children undergoing SDR, potentially improving movement and quality of life.
How similar studies have gone: Prior approaches using electrical stimulation on dorsal roots have shown potential in modulating spasticity in some contexts, but this specific combined intraoperative method is novel.
