Abstract:
1. A method for assessing physiological function in an individual, comprising: (a) placing a sensor superficially on an individual, said sensor comprising a stimulator, a detector, and a flexible connector formed integral with and serving as a mechanical and electrical connection between said stimulator and said detector: said stimulator being shaped to fit a first anatomical site and configured to generate a stimulus and apply said stimulus to stimulate a nerve at said first anatomical site; said detector being shaped to fit a second anatomical site, said detector comprising a plurality of electrodes each configured to detect a response signal generated at said second anatomical site in response to said stimulus, said detector being made so that said electrodes have fixed positions proximate one another; and said connector being configured to mechanically orient said stimulator and said detector relative to one another and automatically position said detector substantially adjacent to said second anatomical site when said stimulator is placed substantially adjacent to said first anatomical site on the surface of an individual, whereby said electrodes are located at proximate points along said surface; and (b) performing nerve conduction studies with at least one of said electrodes to assess physiological function in an individual; wherein said nerve conduction studies comprises: (c) operating said stimulator to stimulate said first anatomical site and monitoring said plurality of electrodes to detect response signals produced at said second anatomical site in response to the stimulation at said first anatomical site; (d) processing the response signals detected by said electrodes, said processing involving an evaluation of selected parameters of each of said response signals and a comparison of said response signals according to the evaluated selected parameters; (e) selecting on the basis of said comparison of said response signals processed in step (d) at least one electrode detecting a response signal characteristic of said second anatomical site; and (f) performing said nerve conduction studies according to step (c) with said at least one electrode selected in step (e).
