Study assessed the feasibility of using an electroencephalogram (EEG) based brain-computer interface (BCI) to control the ambulation of a virtual reality avatar. Study outcomes were to be used to inform the design of a BCI for controlling a functional electrical stimulation (FES) device to restore ambulation in individuals with spinal cord injury (SCI). Study participants were 2 men and 1 woman without disabilities, aged 22 to 39 years. Participants underwent EEG recordings while they imagined standing idle and walking. The EEG signal changes between these two states were used to develop and train an online, real-time BCI system to control the ambulation of an avatar within a virtual environment. All participants were able to immediately control the ambulation of the avatar. Based on the successful implementation of this system, the authors conclude that integrating an EEG-based BCI with a lower extremity FES device is feasible.
