| Research Abstract |
It was shown that the functional electrical stimulation (FES) could restore motor function of paralyzed limbs of the patients with severe motor disabilities due to the spiral cord or cortical area injuries. But on the current FES system, the abilities was limited because the FES users should control the FES stimulator by using their remained physical functions. And the quality of the restored physical functions of the patients' limbs have been evaluated the posture or tension generated by FES stimulation. It is needed to evaluate such a quality of the restored physical function by using more quantitative ways.
In this study, (1) the human interface or brain-computer interface (BCI) which enables the FES patients to control the stimulation devices by their own intensions by detecting the brain activities or eye movements of the users, and (2) the quantitative evaluation methods of the restored physical functions by FES using metabolic properties of the peripheral circulation system, were investigated and developed by the plural measurement of biosignals for improving the functionality of the current FES system.
First, the human interface systems to detect eye-gaze from electrooculogram (EOG) and video image of eye ball taken from user to control FES stimulator were developed.
Second, the BCI system to detect user's intension from electroencephalogram (EEG) during motor imagery or selective attention to the auditory stimuli was developed and the ability to apply to the voluntary control of FES stimulator was investigated.
Third, the Photoacoustic Microscopy system to detect metabolic properties of the peripheral circulation system was proposed. The high-precision measurement of body local temperature was achieved by the proposed system, and the analysis method of the measured temperature by using temporal sequence analysis was introduced.
