A system is provided that is configured to promote sternocostal inhalation for a patient. The system includes: at least one anodal electrode； at least one first cathodal electrode configured to be located above a first set of muscles, which attach to some portion of the patient's ribs； and at least one second cathodal electrode configured to be located above a second set of muscles. The system also includes a controller programmed to: cause the anodal electrode and the first cathodal electrode to electrically stimulate the first set of muscles and cause the anodal electrode and the second cathodal electrode to electrically stimulate the second set of muscles. Stimulation of the first set of muscles and/or the second set of muscles causes contraction of the second set of muscles resulting in an opposing motion of a spine of the patient.
