Smart AFO and 5-Azacitidine to Enhance Mobility in Children With Cerebral Palsy

The goal of this project is to investigate the impact of the Biomotum Ambulo ankle-foot orthosis on gait outcomes in children with Cerebral Palsy. The device will be tested for its orthotic benefits when providing mechanical ankle assistance and its therapeutic benefits when providing progressive, resistance-based ankle exercise. Through a 1:1 randomization, a subset of opt-in participants will also receive a dose of 5-azacitidine (AZA), an FDA-approved drug for pediatric oncology, or a placebo. Research in muscle fibers has shown that AZA aids in muscle growth and regeneration. The use of AZA in this study is an off-label application employed together with the smart AFO intervention to investigate the impact of targeting both muscular and mechanical deficits related to CP. This project will also collect blood samples of participants to investigate the potential genetic and epigenetic correlations with the severity and trajectory of musculoskeletal impairments and with responses to the smart AFO and AZA interventions.
