The invention relates to a device for evaluating a cerebral function state. The device comprises a cerebral oxyhaemoglobin concentration variation obtaining part, a brain function network establishingpart, a typical characteristic obtaining part and an evaluation model establishing part, wherein the cerebral oxyhaemoglobin concentration variation obtaining part obtains the cerebral oxyhaemoglobinconcentration of a stroke patient in a task processing, the stroke patient completes the tasks of finger-to-nose and heel-to-knee according to an instruction in the task processing, and cerebral oxyhaemoglobin concentration variation data is obtained by adopting a near infrared spectrum brain imaging technique. The device for evaluating the cerebral function state based on the cerebral hemoglobininformation has the advantages that the athletic ability of the patient is evaluated based on brain information, the device is innovative, an evaluation result can be offered while the patient just needs to do a few times of corresponding actions based on the provided evaluation device, the operation is simple and convenient, and subjective factors are avoided in the scale scoring process.
Description
technical field [0001] The invention relates to the evaluation of brain function state, in particular to a device for evaluating brain function state. Background technique [0002] Cerebrovascular disease is one of the main diseases that affect the physical and mental health of middle-aged and elderly people, and the most prominent one in cerebrovascular disease is stroke, also known as "stroke". At present, the development trend of stroke in my country is relatively serious, and the number of new stroke patients is about 1.5 million or more every year. In addition, stroke has a high disability rate. According to the latest report, 75% of these new stroke patients lose their ability to work. This has huge implications for both patients and society. Therefore, in order to assist doctors in carrying out targeted training and treatment, and help patients recover, it has become a major and urgent task to objectively evaluate the recovery of patients' motor function.
