Psychophysical tests, including thermometry and vibrametry, are used to assess sensory function of the specific sensory system. Since sensory tests measure subjective responses, and are therefore less objective, evaluation of the patient should take into consideration the influence of various external and internal factors. The tests should therefore be complemented by a thorough physical examination and some others investigations. Neurophysiologically established abnormalities were confirmed morphologically and neuroradiologically. Sensory tests may be helpful in the differential diagnosis of various dysfunctions.
