Detecting voluntary gait intention of chronic stroke patients towards top-down gait rehabilitation using EEG
Abstract:
One
of the recent trends in gait rehabilitation is to incorporate
bio-signals, such as electromyography (EMG) or electroencephalography
(EEG), for facilitating neuroplasticity, i.e. top-down approach. In this
study, we investigated decoding stroke patients' gait intention through
a wireless EEG system. To overcome patient-specific EEG patterns due to
impaired cerebral cortices, common spatial patterns (CSP) was employed.
We demonstrated that CSP filter can be used to maximize the EEG signal
variance-ratio of gait and standing conditions. Finally, linear
discriminant analysis (LDA) classification was conducted, whereby the
average accuracy of 73.2% and the average delay of 0.13 s were achieved
for 3 chronic stroke patients. Additionally, we also found out that the
inverse CSP matrix topography of stroke patients' EEG showed good
agreement with the patients' paretic side.
