Lower limb Motor Imagery (MI) of a sit-stand motion using electroencephalography (EEG) 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 (AO), MI, and motor execution (ME) paradigm with EEG and electromyography (EMG) recording. We examined features including time-frequency analysis of event-related synchronization/desynchronization (ERS/D), corticomuscular coherence, and decoding with Common spatial pattern. Results from time-frequency analysis show a significant difference in ERS/D in alpha and beta. Coherence analysis shows higher functional connection between the lower limb sensorimotor cortex region and the tibialis anterior muscle in AO tasks for VR-HMD. The classification performance from VR-HMD sessions is better in most subjects, though not significantly. The before-after effect was examined and found to be not affected. Results indicate that VR-HMD stimulus for the sit-stand task is a feasible MI paradigm with some benefits over a screen-based method. |
