Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0031] A walking intention recognition method based on brain hemoglobin information, the specific steps are as follows:

[0032] (1). Near-infrared spectral brain imaging technology (NIRS) was used to conduct test experiments, and the subjects completed corresponding walking tasks in a fixed area;

[0033] (2). Through the band-pass filter technology, perform data preprocessing on the cortical hemoglobin concentration signal recorded in the experiment, and extract the cerebral cortex hemoglobin concentration signal in multiple frequency bands;

[0034] (3). For the preprocessed cerebral cortex hemoglobin signal, adopt Z-Score and Teager-Kaiser transformation, and extract signal fe...

Abstract

The invention discloses a method for recognizing the walking intention based on brain hemoglobin information. The method for recognizing the walking intention based on the brain hemoglobin informationcomprises the steps that (1) cerebral cortex hemoglobin concentration signals are obtained, specifically, the cerebral cortex hemoglobin concentration signals are obtained in the mode that a testingexperiment is conducted by applying a near infrared reflectance spectroscopy (NIRS) brain imaging technology, and a subject completes the corresponding walking task in a fixed area; and (2) through aband-pass filtering technology, the cerebral cortex hemoglobin concentration signals recorded in the experiment are subjected to data pre-processing, and the cerebral cortex hemoglobin concentration signals with multiple frequency bands are extracted. The method has the beneficial effects that the NIRS brain imaging technology is applied for the testing experiment, and the method is easy and convenient to operate and has the portable advantage.

Description

technical field [0001] The invention relates to the technical field of intelligent walking aid and rehabilitation training, in particular to a walking intention recognition method based on brain hemoglobin information. Background technique [0002] Population aging is already a significant problem in today's society. The data shows that in 2016, the world population over 60 years old accounted for about 12% of the total number of people, and according to the current trend of society, this proportion will rise to about 21% by 2050. Aging has resulted in a significant decline in motor function and increased physical fragility in the elderly. Most of them suffer from varying degrees of lower limb motor dysfunction, and some elderly people even lose the ability to walk independently. Therefore, assisting these patients with lower extremity motor dysfunction to walk independently can increase their self-confidence, enable them to return to society, increase their sense of socia...
