Facial rehabilitative device based on Robogami (Robotic Origami) platform

Prior art Facial paralysis is a disability that can be caused by infections, accidents, strokes or tumors. There is “an emerging rehabilitation science of neuromuscular reeducation” [1] to help the patients with facial 10 paralysis restore their muscle activity. The therapy method for these patients is still very dependent on the therapist’s experience and even diagnosis remains to be subjective. Rehabilitative devices can enhance the therapy but due to the complexity of the face movements and the spatial limitations there are not many examples of such devices and the few available devices are very limited in number of degrees of freedom (DoF), functionality and adaptability for different therapy methods. The prior art patent documents listed 15 in Table 1 are divided in to three categories: general arrays of stimulating and sensing electrodes that are applicable for different limbs, face specific application of such electrodes (stimulating and sensing), and resistive training masks.
