Sensory assessment of the skin is essential to document the function of the sensory fibers of the tested nerves. The Semmes-Weinstein monofilaments, disk-criminator, electrodiagnostic testing, and Pressure-Specified Sensory Device (PSSD) have been currently used to assess sensory function of peripheral nerves. None of these methods is optimal because of different drawbacks; however, an increasing number of articles, which recognize the reliability of PSSD, have been published during the last decade. In this review, following a short overview on basic physiology and assessment methods of the skin sensory receptors, we compared the sensory assessment methods and summarized the applications of the PSSD in the field of different clinical areas, mainly peripheral neuropathies, breast, and flap surgery.
