Selective tissue conductance/thermography sensor apparatus
First Claim
1. A diagnostic device for assessing pain, abnormal sensation or sympathetic dysfunction in a human being or animal, comprising:
- two spaced-apart electrodes mounted together for measuring conductance of human or animal tissue over a selected region;
a temperature sensor positioned adjacent the electrodes for measuring tissue temperature in the selected region, said temperature sensor adapted to be used both with and without the temperature sensor being in direct contact with a subject'"'"'s skin; and
circuit means for indicating measured temperature and conductance to a user for localizing a region of sympathetic nerve dysfunction.

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.
