| Outline of Final Research Achievements |
The aim of this study was to examine the influence of vibratory stimulation-induced kinesthetic illusion on brain function with hemiparetic stroke patients by using EEG analysis. As a neurophysiological index to evaluate brain function, the μ-rhythm, which is present mainly in the kinesthetic cortex and is attenuated by movement or motor images, was used. Calculated data were compared using analyses of Source Localization by the eLORETA. The results showed that, in the resting condition, the kinesthetic cortical μ-rhythm appeared in the sensorimotor cortex and supplementary motor cortex. On the other hands, in the vibratory stimulation condition, no μ-rhythm appeared as well as healthy individuals in the sensorimotor cortex. These findings suggested that kinesthetic illusion increases the neural activities of the sensorimotor cortex.
