Patent number: 9526889Abstract: The electromagnetic stimulation device contains at least a positive electrode and at least a negative electrode. An insulating gap having width of a first distance is maintained between the positive and negative electrodes. The positive and negative electrodes are at least at a second distance away from a nerve to be stimulated.
