Abstract
The present invention relates to a device for delivering dual point pressure sensations to a subject to provide not only tactile sensory forces, but also precise gradations of these forces in a single hand-held unit. The operator can, by varying the distance between extensions, know exactly when a subject feels a dual point sensation in order to evaluate peripheral nerve sensory function.
Claims8
A device for measuring peripheral nerve sensory response in a subject comprising a body portion, said body portion comprising a top disk of substantially circular geometry and a bottom disk of substantially circular geometry, said top disk and bottom disk having substantially equal diameters and concentric circumferences when joined about a common centrally located axis, each of said top and bottom disks being rotatable with respect to one another about said centrally located axis and each being provided with a plurality of tip members having extensions such that when said top and bottom disks are joined, said extensions form pairs thereof such that distances between said pairs of extensions can be adjusted by rotating said top and bottom disks with respect to one another about said axis whereby nerve sensory response can be measured by determining when the subject can differentiate pairs of extensions as spacing between said extensions is so adjusted.
