Research projects designed to improve classification and treatment for children with cerebral palsy. Using advanced neuroimaging techniques in the kennedy krieger institute's kirby research center for functional brain imaging -- including diffusion tensor imaging (dti) to more precisely characterize brain injury -- phelps center researchers have identified specific white matter pathways that carry messages from one part of the brain to another. viagra without a doctor prescription buy viagra buy viagra online buy viagra cheap generic viagra cheap viagra cheap viagra viagra for sale cheap viagra Dti, a form of magnetic resonance imaging, shows white matter pathways in three dimensions, with color codes that identify individual bundles. Injury to these pathways is an important cause for the motor disabilities seen in children with cerebral palsy. Previous imaging techniques have not been able to visualize white matter in such detail. In two children born prematurely who have been studied thus far, the research team was surprised to find injury to white matter pathways in unexpected areas of the brain. Although they anticipated injury in pathways that carry messages to the arms and legs from motor control areas in the front of the brain, these children had abnormal pathways in the back of the brain where sensory information is processed. This suggests that sensory processing may be very important for controlling tone and movement in children. In the future, dti may be used to select appropriate therapy for children with cerebral palsy. For example, if sensory pathways in the brain are abnormal, therapies that activate them, such as gait training or therapeutic horseback riding (hippotherapy), might be beneficial. A second research project, in collaboration with dr. Amy bastian, involves precise measurements of motor function. In dr. Bastian's motion analysis lab, quantification of motor abilities in children with cerebral palsy is being investigated. It is anticipated that the results of this work will improve classification of cerebral palsy, as well as evaluation of the effectiveness of various rehabilitative interventions, from oral medications to intrathecal baclofen. Overall, research projects are designed to improve treatment for children with cerebral palsy and are formulated on. viagra40
