ABSTRACT:
A diagnostic device for measuring selective tissue conductance and temperature is described which can be used to assess pain, abnormal sensation or sympathetic dysfunction in a human being or animal. Two spaced-apart electrodes are mounted together for measuring conductance of tissue over a selected region. A temperature sensor is positioned adjacent the electrodes for measuring tissue temperature in the selected region. A circuit is provided for indicating measured temperature and conductance to a user for localizing a region of sympathetic nerve dysfunction. In preferred form, the device indicates measured temperature and conductance visually and/or audibly by utilizing a measurement of both selective tissue conductance and temperature together. A more specific and useful diagnosis of sympathetic nerve dysfunction may be made than through the use of sensing either conductance or temperature separately.
