Neurosurgery to restore function in cerebral palsy: current practice and emerging therapies

Area of Science:

• Neurology
• Neurosurgery
• Rehabilitation Medicine

Background:

• Cerebral palsy (CP) impacts 1.5-2.5 per 1,000 live births.
• Characterized by diverse movement disorders (spasticity, dystonia) affecting motor function and quality of life.
• Medically refractory cases necessitate advanced treatment strategies.

Purpose of the Study:

• To review surgical and neuromodulatory interventions for CP-associated movement disorders.
• To evaluate the efficacy and applicability of various treatment options.
• To inform individualized treatment selection for CP patients.

Main Methods:

• Review of existing literature on surgical and neuromodulatory techniques for CP.
• Analysis of interventions including Selective Dorsal Rhizotomy (SDR), peripheral neurectomies, Intrathecal Baclofen (ITB), Deep Brain Stimulation (DBS), Spinal Cord Stimulation (SCS), and Focused Ultrasound.
• Consideration of patient-specific factors like phenotype, functional goals, and age.

Main Results:

• SDR and peripheral neurectomies show efficacy for spasticity management.
• ITB effectively reduces spasticity and dystonia, with monitoring for complications.
• DBS is effective for dystonia-predominant CP; cerebellar DBS and SCS show emerging promise.
• Focused ultrasound is an investigational noninvasive option.

Conclusions:

• Multidisciplinary evaluation is crucial for selecting appropriate interventions.
• Individualized, mechanism-based treatment algorithms are key to optimizing outcomes.
• Advancing understanding of CP pathophysiology will refine future therapeutic strategies.
