Method and system for involuntary movement artifact suppression in electromyographic signals

This application relates to the field of neuroengineering technology and discloses a method and system for suppressing involuntary movement artifacts in electromyographic signals. The method includes: simultaneously acquiring epidural nerve electrical signals and autonomic nerve excitability signals of spinal cord segments; performing blind source separation processing; generating movement intention classification probabilities; calculating spinal cord reflex gain indices; when the spinal cord reflex gain indices exceed the reflex gain threshold, generating phase-cancelling electrical stimulation and peripheral mechanical interference signals; and adjusting the electrical stimulation parameters and interference parameters according to the intervention effect. This application moves the signal acquisition node from the muscle surface where signals are already confused to the spinal cord level where the signal aliasing is less. By reducing the degree of aliasing between descending control signals and segmental reflex signals through blind source separation, movement intention recognition is mainly based on the separated descending control signals, thereby reducing the risk of spasticity artifacts being misjudged as movement intentions and improving the safety of exoskeleton-assisted movement.
