Assignee: KEIO UNIVERSITY
Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 8:
9. A non-transitory computer readable medium storing a program that, when executed, causes a computer controlling a biometric information processing device that processes biometric information of a subject to:
monitor brain waves in the somatosensory motor cortex of regions of the brain of a patient that are ipsilateral and contralateral to a hemiplegic shoulder and elbow of the patient while showing the patient imagery designed to cause the patient to imagine moving the hemiplegic shoulder and elbow,
calculate event-related desynchronization (ERD) values from the monitored brain waves, and
in response to satisfying at least two predetermined conditions, cause a movement assisting device connected to the hemiplegic shoulder and elbow to execute a predetermined motion that assists movement of the hemiplegic shoulder and elbow,
wherein the at least two predetermined conditions include (i) a determination that at least one of the calculated ERD values in the region of the brain of the patient that is ipsilateral to the hemiplegic shoulder and elbow has exceeded a predetermined threshold while the imagery is being shown to the patient and (ii) a first determination that at least one of the calculated ERD values in the region of the brain contralateral to the hemiplegic shoulder and elbow does not exceed a second predetermined threshold of activation level.
