The bereitschaftspotential for rise of stand-up towards robot-assist device preparation

Recently, many researchers have been exploiting brain computer interface systems that provide a path to assist neurocognitive disorder and motor-disabled persons. In this study, the electroencephalography and electromyography were recorded in the complex, dynamic and voluntary behavior, the rise of stand-up. The negative-going potential, Bereitschaftspotential (BP), was induced before the onset of the rise. Before the onset of the movement BP had the negative peak. After the peak, the motor- and post motor-related potential were evoked. BP negative peak values significantly correlated with the latency from the start-cue to the onset of the movement. BP could be used for the support devices for the rise of stand-up. This is the first step toward developing the robot-assisted device for the motor-disabled persons to stand up.
