Neuro Developmental Delay

This observational patient registry aims to describe the clinical phenotypes and genetic findings of Vietnamese children with movement disorders of unknown etiology. Eligible participants are children with clinically confirmed movement disorders after evaluation by pediatric neurology specialists and after exclusion of clear acquired causes. The study will collect clinical data, neurological examination findings, available laboratory and imaging results, and video recordings of abnormal movements when consent is provided. Blood samples will be collected for whole-exome sequencing and related genetic analysis. Genetic variants will be classified according to accepted clinical genetics standards and compared with the patients' clinical phenotypes. The study is expected to improve understanding of the phenotypic and genotypic spectrum of pediatric movement disorders in Vietnam, support genetic counseling, and evaluate how genetic results may influence diagnosis, follow-up, prognosis, and treatment planning.

This randomized clinical trial compares the effects of aquatic therapy and conventional sensory room intervention on adaptive neural responses and sensory-motor praxis in children with Monochannel Sensory Processing Disorder. Participants will be randomly assigned to one of the two intervention groups. Outcomes related to sensory processing, sensory-motor praxis, and adaptive responses will be evaluated before and after treatment. The study aims to determine whether aquatic therapy provides additional benefits compared with conventional sensory room intervention in improving sensory integration and functional performance in affected children.
