Control of functional electrical stimulation using motor unit action potentials

A method comprising:

• recording surface electromyography (EMG) activity from a target anatomy of a subject using an electrodes garment worn on the target anatomy and including electrodes disposed to contact skin of the target anatomy;
• recording electroencephalography (EEG) activity of the subject concurrently with the recording of the surface EMG activity;
• training at least one EMG decoder to decode surface EMG activity to determine at least one cortical motor intended movement of the target anatomy using the recorded surface EMG activity labeled with the cortical motor intended movements of the subject determined from the recorded EEG activity to generate at least one trained EMG decoder;
• recording further surface EMG activity from the target anatomy of the subject using the electrodes garment wherein the further surface EMG activity is recorded without concurrently recording EEG activity;
• using the at least one trained EMG decoder, determining information about a cortical motor intended movement of the target anatomy based on the further surface EMG activity, the determined information including a start time for the cortical motor intended movement;
• and
• based on the determined information, delivering functional electrical stimulation (FES) effective to implement the cortical motor intended movement via the electrodes of the electrodes garment.
