Electrical stimulation tactile perception method

Abstract

The invention discloses an electrical stimulation tactile perception method. According to the invention, a high-density electrode array composed of functional electrical stimulation electrodes is used as a single electrical stimulation module, and movement rehabilitation of fine hand actions and tactile feedback of different contact points of the hand are realized through the combination of the electrical stimulation electrodes. According to the method, nerve muscle related to hand movement and tactile sensation is directly stimulated, both movement rehabilitation and tactile feedback are direct effects generated by electrical stimulation, natural intuition of human beings is met, and the training cost of a user is greatly reduced. According to the invention, by using the high-density electrode array, the spatial resolution of the electrical stimulation system is improved, and the defects that an existing electrical stimulation system is insufficient in spatial resolution and not fine enough in stimulation function are greatly overcome. According to the invention, electrode combinations corresponding to different fine actions and different fine position tactile sensation can be quickly and accurately searched.

Description

technical field [0001] The invention relates to an electric stimulation tactile perception method, which belongs to the technical field of artificial intelligence medical equipment. Background technique [0002] The functional electrical stimulation system is a technology used for motor rehabilitation and tactile feedback induction [1]. It can artificially apply current stimulation to specific nerve parts to drive patients with stroke and other movement disorders to automatically contract the corresponding muscles and generate limb movements. At the same time, since the sensory neural circuits of stroke patients are still intact, electrical stimulation of the patient's sensory nerves can be used to artificially induce the patient's corresponding hand tactile perception, thereby helping stroke patients gradually restore the tactile feedback function. Through the motor function rehabilitation of "patient-electrical stimulation-exercise" and the tactile feedback of "exercise-el...

Problems solved by technology

[0007] At the same time, improving the spatial resolution of the functional electrical stimulation system requires a more refined and accurate quantification of the stimulation points and possible combinations of points, which depends on the anatomical structure of the arm muscles, and the muscle anatomy has individual differences. None of the existing systems and research can solve the problem of quickly and accurately searching for the optimal electrode array that can produce different hand movements and tactile positions for each individual.
