pinprick test

    0.01 sec.
pinprick test,
a test of a person's ability to detect a cutaneous pain sensation and to differentiate such sensations from pressure stimuli. The test is performed with a pin or needle gently applied to a skin area where it cannot be observed by the subject. The application of the pin is alternated with the pressing of a dull object against the skin. Care is taken to prevent penetration of the dermis, and the sharp object used should be sterilized or discarded after the test.
