Abstract

Spectrum mapping reflects the strength of brain electrical activity in different frequency band. The current study analyzes changes in electroencephalography (EEG) after spinal cord injury (SCI) on the basis of spectrum mapping. Comparing spectrum mappings of SCI patients and normal subjects, the fact that beta rhythm dominated in brain electrical activity during walking period was concluded. In addition, the proportion of delta wave increased and slightly exceeded that of beta wave after spinal cord injury and power values in delta band of SCI patients performed greater than that of normal subjects.
