The functional connectivity between cortex and muscle during motor tasks can change after stroke. Motor rehabilitation aims at restoring it, either by re-establishing “close-to-normal” connectivity or supporting the development of alternative pathways. With the ultimate aim to design a rehabilitative approach based on a combination of Electroencephalographic (EEG) and Electromyographic (EMG) signals, we studied how different processing pipelines affect the extraction of a potential hybrid feature to discriminate movement tasks. Such feature will be employed in a novel hybrid Brain-Computer Interface system for motor-rehabilitation. In this setting, the control feature will be derived from a combined EEG and EMG connectivity pattern estimated online during upper limb movement attempts.
