The main electrode stimulates the nerves and muscles related to swallowing and articulatory function through  specific low-frequency pulse current, improves the contraction and movement function of muscles, relieves neuron  paralysis, promotes nerve recovery, and realizes the recovery and reconstruction of the reflex arcs of swallowing and  speech; the auxiliary electrode outputs cerebral emulation bioelectricity, and stimulates the nucleus of the  cerebellum parietale through electrodes affixed to the mastoid process of the back of the ear, improves the neural  conduction and promotes the recovery of neural function. The auxiliary electrode and the main electrode output  synergize to promote the functional recovery of patients with dysphagia and dysarthria.
