要約(日本語): Lower limb motor imagery (MI) of a sit-stand motion using electroencephalography has been studied with the aim of rehabilitation. We aim to explore the use of self-perspective stimulus using virtual reality head-mounted displays (VR-HMD), which has promising results in upper limb MI tasks but is yet to be explored in sit-stand. We compare VR-HMD and on-screen stimulus using an action observation, MI, and motor execution paradigm. Features such as event-related synchronization/desynchronization (ERS/D), band power, common spatial pattern (CSP), and movement-related cortical potential are examined. Results from time-frequency analysis show a significant difference in ERS/D in alpha and beta. Classifications of CSP between sitting and standing are better in VR sessions for most subjects.
