An infant's risk of developing neuromotor impairment is primarily assessed through visual examination by specialized clinicians. Therefore, many infants at for go undetected, particularly in under-resourced environments. There thus a need to develop automated, clinical assessments based on quantitative measures from widely-available sources, such as videos recorded mobile device. Here, we automatically extract body poses and movement kinematics the at-risk (N = 19). For each infant,...

Disease-causing variants in STXBP1 are among the most common genetic causes of neurodevelopmental disorders. However, phenotypic spectrum STXBP1-related disorders is wide and clear correlations between variant type clinical features have not been observed so far. Here, we harmonized data across 534 individuals with analysed 19 973 derived terms, including phenotypes 253 previously unreported scientific literature. The overall landscape characterized by abnormalities 95% seizures 89%...

Large tracts of lowlands have been drained to expand extensive agriculture into areas that were historically categorized as wasteland. This expansion in necessarily coincided with changes ecosystem structure, biodiversity, and nutrient cycling. These impacted not only the landscapes which they occurred, but also larger water bodies receiving runoff from land. New approaches must append current efforts toward land conservation restoration, continuing impacts waters is an issue major...

Abstract STXBP1-related disorders are among the most common genetic epilepsies and neurodevelopmental disorders. However, longitudinal epilepsy course developmental end points, have not yet been described in detail, which is a critical prerequisite for clinical trial readiness. Here, we assessed 1281 cumulative patient-years of seizure histories 162 individuals with established natural history framework. characterized by dynamic pattern seizures first year life high variability trajectories...

The purpose of this brief report was to compare the immediate effects surface functional electrical stimulation (S-FES) and percutaneous (P-FES) tibialis anterior applied during gait in a child with hemiplegic cerebral palsy. A three-dimensional analysis conducted while an 11-yr-old girl right hemiplegia walked S-FES, P-FES, no stimulation. results indicated that both P-FES S-FES increased dorsiflexion at initial contact, peak swing, mean swing compared walking without increase greater as...

Eight CP (six diplegia, two hemiplegia; mean age 9 years 1 month [SD y 4 mo; range 7 11 mo to 10 mo]) had electrodes implanted into the gastrocnemius (GA) and tibialis anterior (TA) muscles their involved limbs. Stimulation was provided appropriate phases cycle three conditions (GA...

Aims Typical infant movement is characterized by a high degree of motor exploration, error, and variability. However, children with cerebral palsy (CP) often cannot create these experiences due to their neuromotor impairments.
