Abstract

The invention discloses a multi-source information fusion control method for functional electrical stimulation, which belongs to the technical field of rehabilitation medical equipment for the disabled. The user imagines the first specific action, extracts the characteristics of the imagined action, and starts the functional electrical stimulator; For the second specific action or the third specific action and the fourth specific action or the fifth specific action, collect the corresponding EEG and cerebral blood flow signals; adjust the original value of the electrical stimulation time and the electrical stimulation frequency by stimulating the stimulator ; The error and the rate of change of the error are taken as the input of the fuzzy controller, and the precise amount of the stimulus current intensity is taken as the output of the fuzzy controller; the error and the rate of change of the error are deduced by using the control rule and the membership function, and the fuzzy value of the stimulus current intensity is obtained. Defuzzification processing is performed to obtain the precise amount of stimulation current intensity; the user imagines the sixth specific action, and turns off the electrical stimulation system through the corresponding fusion characteristics of EEG and cerebral blood flow signals.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation medical equipment for the disabled, and in particular relates to a multi-source information fusion control method for functional electrical stimulation. Background technique [0002] FES (Functional Electrical Stimulation, Functional Electrical Stimulation) is a technology that stimulates limb motor muscles and peripheral nerves through current pulse sequences to effectively restore or reconstruct part of the motor function of paraplegic patients. At present, for the treatment of paralyzed patients with spinal cord injury, due to the weak regeneration ability of the spinal cord, there is no effective treatment method that can directly repair the injury. The implementation of functional rehabilitation training is an effective measure. According to statistics, the number of paralyzed patients with spinal cord injury is increasing year by year, and functional rehabilitation training is an urge...
