Abstract
A technique and associated device for stimulating multiple electrodes with multiple electrical signals in multiple regions of the spine without injury to the patient. The electrodes are applied to respective sides of the patient's spine, and a first electrical signal is applied to any electrodes in a treatment area of the lumbar region of the patient's spine, a second electrical signal is applied to any electrodes in a treatment area of the thoracic region of the patient's spine, and a third electrical signal is applied to any electrodes in a treatment area of the cervical region of the patient's spine to induce osteogenesis in at least one of the respective treated area's of the patient's spine. The first, second, and third electrical signals respectively generate different electrode currents in the respective treated areas and are ideally selected to create current densities that are approximately equal in respective treatment areas. The electrodes may include electrode pairs or strip electrodes placed either side of the patient's spine in the respective treatment areas.
