To assess the function of a patient's sensory system, a tuning fork should first be applied to each hand and foot to assess vibratory sensation. A cotton wisp brushed over each extremity, chest and abdomen, ascertains the patient's sensation to light touch. With the sharp end of a broken tongue depressor, the patient's pinprick sensation over each extremity, chest and abdomen, should be determined. Finally, using a fresh alcohol swab, the patient's sensation to temperature should be tested.
