Abstract:
1. A method for positioning an electrode array comprising the steps of: a) placing a patient in a neutral upright position; b) locating the fourth lumbar vertebrae of the patient; c) marking the fourth lumbar vertebrae; d) locating the seventh thoracic vertebrae; e) measuring a first distance between the fourth lumbar vertebrae and the seventh thoracic vertebrae; f) locating the left superior iliac crest at its most lateral point; g) measuring a second distance between the most lateral aspect of the left iliac crest to the fourth lumbar vertebrae; h) positioning an array of electrodes on the patient by aligning one of the electrodes in the electrode array over the marking of the fourth lumbar vertebrae; and i) correlating each of the electrodes in the electrode array to the underlying anatomical structures of the patient using the measured first and second distances and the dimensions of the electrode array.
