OBJECTIVE: Describe the use of the PSSD (Pressure specified sensory Device) for the diagnosis of carpal tunnel syndrome. METHODS: The PSSD is a tool that incorporates a pressure transducer with two prongs, linked to a computer capable of measuring the cutaneous pressure thresholds. The patients were divided in two groups: Group 1- patients neither with superior limb neuropathy nor renal insufficiency. Group 2- patients with carpal tunnel syndrome related to hemodialysis. Group 2 - patients with carpal tunnel syndrome but no renal insufficiency. RESULTS: The results showed, for two of the four parameters measured, that the group 2 had more benefits for the diagnosis of carpal tunnel syndrome than group 3. CONCLUSION: The PSSD is useful as a diagnostic tool in hemodialysis-related carpal tunnel syndrome Level of Evidence: Level II, development of diagnostic.
