How does a short history of spinal cord injury affect movement-related brain potentials?

摘要: Brain plasticity following spinal cord injury (SCI) has been studied by a wide range of neurofunctional techniques, which tend to have low temporal resolution or overlook cognitive preparatory processes. This study tried overcome both limitations recording the movement-related brain potentials using an experimental task somewhat similar contingent negative variation paradigm. The aim was look for amplitude topographic distribution changes at early stage SCI. Hence, electrical activity patients who had clinical history less than 6 months paraplegia recorded and compared with that two groups healthy volunteers. None able move their toes, but they were asked prepare carry out this movement try execute it in same way as one control groups. other group instructed conduct not it. Results did show significant differences readiness potential between controls. However, topography observed more participants conducted movement, whereas greater similarity found motor movement. These findings suggest take place after SCI may be shown earlier potential.
