Tactile feedback ankle joint functional training system based on brain-computer interface

Abstract

The invention discloses a tactile feedback ankle joint functional training system based on a brain-computer interface. The tactile feedback ankle joint functional training system comprises a trainingchair for a user to train and use, a user interface module, an electroencephalography collecting and treating module and a control feedback module, wherein the user interface module comprises a display screen and a host computer, and can provide a cartoon based on steady-state visual sense inducing to allow the user to watch; the electroencephalography collecting and treating module is used for performing collecting, filtering treatment and amplifying treatment on generated eeg signals after the user watches the cartoon, and transmitting the treatment result to the control feedback module; andthe control feedback module is used for controlling the intensity and the frequency of a vibrating module through a single chip microcomputer according to the eeg signals, and performing vibration training on shank muscle of the user, and the user can control the position of training lateral vibration through an active intention. According to the tactile feedback ankle joint functional training system disclosed by the invention, a brain-computer interface manner is adopted, and the eeg signals of the user are extracted to perform tactile training, so that active intention training is realized; and based on the training of steady-state visual sense inducing technique, the gait cycle in a walking process is simulated, and the proprioceptive sensation and abnormal gait training of the user are facilitated.

Description

technical field [0001] The invention belongs to the technical field of training devices, and in particular relates to a brain-computer interface-based tactile feedback ankle joint function training system. Background technique [0002] At present, the tactile training for the ankle joint of stroke users usually increases the user's proprioceptive input through occupational training, improves the excitation of damaged neural structures or promotes the formation of new pathways to restore normal function. However, traditional training is time-consuming and labor-intensive. Due to passive training, the user's participation in the training process is poor, which is not conducive to the user's nerve and proprioception training. The development of brain-computer interface technology provides a basis for users to perform tactile feedback training through active intention. [0003] The training of abnormal gait and tactile feedback of stroke users is very important. At present, the...

Problems solved by technology

[0003] The training of abnormal gait and tactile feedback of stroke users is very important. At present, the existing training is time-consuming and laborious and lacks pertinence. It lacks the use of the user's active intention to achieve ankle joint tactile feedback and abnormal gait improvement.
