Multi-mode brain-computer interface control method for soft-body rehabilitation manipulator

Abstract

The invention discloses a multi-mode brain-computer interface control method for a software rehabilitation manipulator. When a user performs active rehabilitation training in daily life, a multi-source signal control mode is constructed by synchronously collecting EEG, EMG and EoG signals , use the double blink of EOG signal to switch brain / muscle / oculoelectric mode in turn, and preprocess the signal of the corresponding mode, feature extraction, pattern recognition, and the classification results are converted into control signals through real-time processing of the lower computer and sent to the software The rehabilitation manipulator drives the user's fingers to complete relevant training tasks, and its control results are fed back to the user in real time, so as to achieve the purpose of active rehabilitation training for the user. The multi-mode brain-computer interface control method of the present invention has the advantages of multiple active control modes, multiple control commands, and strong real-time performance. The software rehabilitation manipulator has high safety, good comfort, low noise, light weight, portability, and low cost, and has great advantages. prospects for clinical application.

Description

technical field [0001] The invention belongs to the interdisciplinary technical field of rehabilitation medicine and neurological function information, and relates to a multi-mode brain-computer interface control method for a software rehabilitation manipulator. Background technique [0002] In modern society, with the arrival of an aging society, a large number of stroke users cause motor dysfunction. In addition, the number of users with nerve or limb injuries due to work-related injuries, traffic accidents, wars and diseases has also increased significantly, which brings great inconvenience to users' life and work. At present, brain injury (stroke, traumatic brain injury, brain tumor, spinal cord injury, etc.) is one of the main reasons for the loss of hand motor function. Studies have shown that the 3 months after the initial onset is the golden period for functional recovery of brain-injured users. To a certain extent, intensive training can repair damaged nerves, whic...

Problems solved by technology

However, regardless of the single-mode or dual-mode active control method, there are not many control commands generated, and the real-time control is not strong, which cannot meet the needs of active control of basic hand movements in daily life.

At present, no method has been found to actively control the software rehabilitation manipulator using the brain-computer interface of the three modes of brain / muscle / eye electricity.
