Filter by:This research study will combine non-invasive spinal stimulation with mobility devices to examine the acute impact of the individual and combined effects of these innovative techniques on mobility in children with cerebral palsy.
The aim of the study is to develop an accessible, reproducible ultrasound tool for objective clinical measurement of brain circulation in preterm infants in order to identify infants being at risk for preterm brain injury at an early stage. In the future, the results of this study might be useful to select those infants for early interventions aimed at preventing brain injury. In this study we will identify the normative values of the internal cerebral vein velocity in a reference cohort of stable preterm infants. This stable group of preterm infants is defined as all preterm infants with a birth weight appropriate for gestational age, and without major complications (such as a severe intracranial hemorrhage, severe hemodynamical instability, birth asphyxia) or major congenital malformations. In this group we will identify subgroups based on moments of clinical instability (sepsis, temporary hypotension, NEC, need for invasive respiratory support) or based on outcome parameters (IVH, PVL, developmental outcomes)
This is a randomized controlled trial, comparing 3 months of intensive leg exercise to standard physiotherapy care for the improvement of gross motor function in young children with spastic diplegia.
Preterm and very preterm infants are at risk of developing encephalopathy of prematurity and long-term neurodevelopmental delay. Magnetic resonance imaging (MRI) allows the characterization of specific features of encephalopathy of prematurity, including structural changes of brain white matter and gray matter. This study wants to investigate important evidence that early repeated high-dose rhEPO(5250 IU/kg) treatment improves long-term neurological outcomes in very preterm infants and without obvious adverse effects.
Extremely low birth weight (ELBW), birth weight less than or equal to 1000 g, infants are at high risk for developing brain injury in the first week of life. Intraventricular hemorrhage (IVH) and periventricular leukomalacia (PVL) are the most common injuries in this group of infants. Their incidence is inversely proportional to gestational age (GA) and birth weight (BW). These lesions are associated with neurodevelopmental delay, poor cognitive performance, visual and hearing impairment, epilepsy, and cerebral palsy; and instability of systemic hemodynamics during transition from intra- to extra-uterine life and during the early neonatal period is believed to be at their genesis. While the incidence of ultrasound- diagnosed cystic PVL has decreased dramatically over the last 2 decades, diffuse PVL detected by magnetic resonance imaging (MRI) is still prevalent in survivors of neonatal intensive care. Moreover, PVL, even when non-cystic, is associated with decreased cortical complexity and brain volume and eventual neurocognitive impairment. Currently, clinicians lack the tools to detect changes in cerebral perfusion prior to irreversible injury. Unfortunately, the incidence of brain injury in ELBW infants has remained relatively stable. Once translated to the bedside, the goal of this research is to develop a monitoring system that will allow researchers to identify infants most at risk for IVH and PVL and in the future, intervention studies will be initiated to use the changes in cerebral perfusion to direct hemodynamic management. The purpose of this study is to first understand the physiology of brain injury and then to eventually impact the outcomes in this high-risk group of infants by assessing the ability of the diastolic closing margin (DCM), a non-invasive estimate of brain perfusion pressure, to predict hemorrhagic and ischemic brain injury in ELBW infants. The information collected for this study will help develop algorithms or monitoring plans that will maintain the appropriate brain perfusion pressure and thereby, prevent severe brain injury.
