Characterizing the impact of therapist mediated visual feedback in robotic assisted gait training: a multimodal eye tracking and HD EEG study

Patient’s active participation to the rehabilitative process is crucial to the achievement of favourable outcome. The growing interest in robotic rehabilitation and its daily employment in clinical practice has been including the robot as a third actor in the one to one Physiotherapist Patient (Pht Pt) interaction typical of traditional rehabilitation processes . The use of performance related visual feeedback (FB) during robotic gait assisted therapy (RAGT) improves the human robot interaction and helps the patients to adapt their gait patterns also enhancing the patient’s motivation. Objective: To investigate how the different visual FB types impact on patient engagement and Pht Pt interaction during RAGT in individuals with incomplete spinal cord injury iSCI by means of a multimodal approach including high density EEG ( hdEEG ) and eye gaze data.
