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

Claim 11:
12. A biometric information processing device comprising:
a biometric information detecting unit configured 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,
an information processing device configured to calculate event-related desynchronization (ERD) values from the monitored brain waves, and
a movement assisting device configured to be connected to the hemiplegic shoulder and elbow and to, in response to at least two predetermined conditions being satisfied, 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 first predetermined threshold while the imagery is being shown to the patient and (ii) a 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.
