Abstract: The invention is directed to a shoulder press for holding the shoulders of a subject out of the way of an X-ray view by exerting a downward pressure upon the shoulders by means of the device so that all the vertebrae are visible in the X-ray, the shoulder press comprising a horizontal member and two vertical members, the vertical members having attachments for placing on the shoulders of the subject.

Abstract: A stocking or sleeve for wearing or placing on a part of a subject's body for guiding placement of electrodes during monitoring and evaluating of electroneurophysiological data such as mixed and dermatomal nerve conduction latencies and amplitudes, and spontaneous electromyogram, in both clinical and intraoperative settings. The stocking or sleeve has designed into the fabric positioned apertures corresponding to a specific electrode montage, wherein the electrodes are placed on the surface or just beneath the surface of the skin of a subject at the positions of the apertures. The apertures may be color-coded or otherwise marked, or may be markable, to distinguish particular electrodes for positioning at specific sites on the subject's body. The stocking or sleeve is suitable for all kinds of electrodes. A preferred embodiment of the present invention is the use of the stocking or sleeve with a wireless biosensor electrode.
