The Pressure Specified Sensory Device (PSSD) is the most accurate way of testing the lower extremity for sensory deficits. The PSSD is one of the best sensory measuring devices available that can quantify and record both specific peripheral nerve threshold levels and peripheral nerve innervation density (which reflects axonal degeneration). The PSSD is able to quantify pathologic changes at subclinical levels and is pain free.
