Motor nerve feedback system based on optical brain imaging and training method

Abstract

The invention discloses a motor nerve feedback system based on optical brain imaging and a training method. The system comprises optical brain imaging equipment, a central processing unit and a display; the optical brain imaging equipment is used for collecting light intensity signals of brain blood oxygen of participants; the central processing unit is used for preprocessing the collected light intensity signals to form bias indexes, comparing the bias indexes to obtain rewarded or punished neural feedback information, and converting the neural feedback information into visual signals; and the display is used for displaying the neural feedback information converted into the visual signal and guiding rehabilitation training of the participant. The method comprises the steps that light intensity signals of brain blood oxygen of participants in training are collected through the optical imaging device and converted and formed into neural feedback signals through the central processing unit, and the participants are guided to adjust training through the neural feedback signals. According to the invention, the effect of rehabilitation training is reflected through the change of the biased index, so that the rehabilitation training can be guided more effectively.

Description

technical field [0001] The invention relates to the technical field of rehabilitation aids, in particular to a motor nerve feedback system and training method based on optical brain imaging. Background technique [0002] Damage to nerves such as stroke, traumatic brain injury, or various types of brain surgery often leads to motor impairment. Neurofeedback collects participants' brain neural responses in real time and presents them to participants in a timely manner, requiring participants to selectively enhance or inhibit the feedback signal, so that participants can autonomously adjust brain neural activities to a certain extent, thereby promoting or Enhanced functionality restored. In the prior art, various neurofeedback methods have been successfully applied to sports rehabilitation, such as: neurofeedback based on electroencephalogram (EEG) signals has been used for rehabilitation of movement disorders (A Mottaz, T Corbet, N Doganci, C Magnin, P Nicolo , A Schnider, A...
