Embodiment

[0035]1. Headgear design: The brain regions tested in this study are mainly based on Broadman's hierarchical anatomy system of the brain, which was proposed by German scientist Korbian Brodmann. This system is currently the most commonly used and widely used system, and is favored by most brain science researchers. Under the Broadman system, according to the above-mentioned brain area studies, this paper identified the PFC and M1 areas as important monitoring and analysis areas. In order to improve the measurement accuracy of the target brain region, the 10-20 system was used to locate the brain region in the experiment. By configuring the layout of the light transmitter and receiver through this system, the final helmet headgear layout is shown in the figure.

[0036] The specific process of the experiment: Before the task started, the subjects were kept in a state of rest for 50 seconds, and then considering the difficulty of the action target, the subjects were asked to co...

Abstract

The invention discloses an identification method for determining whether a movement task reaches the final goal. An identification method for determining whether a motor task has reached the final goal of the present invention includes: (1) obtaining the hemoglobin concentration in the cerebral cortex, wherein the hemoglobin concentration in the cerebral cortex is tested by applying functional near-infrared spectroscopy brain imaging technology (fNIRS). In the experiment, the chopsticks and the ping-pong ball were used as the target, and when performing the task, the subjects needed to complete the task in a natural state;" In, the hemoglobin concentration in the cerebral cortex recorded during the exercise phase. Beneficial effects of the present invention: 1. The present invention uses near-infrared spectroscopy brain imaging technology to carry out test experiments, which is easy to operate, does not require high external environment, has low sensitivity to environmental noise, and does not produce any negative effect.

Description

technical field [0001] The invention relates to the technical fields of intelligent power assistance and rehabilitation training, in particular to an identification method for determining whether a movement task reaches the final goal. Background technique [0002] Stroke is one of the most dangerous cardiovascular and cerebrovascular diseases with extremely high mortality and disability rates. As a disease with cerebral ischemia and hemorrhagic injury as its main clinical manifestations, severe cerebral stroke can cause permanent neurological damage. If not diagnosed and treated in time, it can cause serious complications and even death. It is currently one of the leading deadly diseases in the world. There are more than 15 million cases worldwide each year. In the United States, nearly 795,000 people experience a stroke each year, 185,000 of whom are recurrent. On average, every 40 seconds, one person in the United States has a stroke. Of the 110,000 people who suffer ...
