Abstract: A device for measuring the sensitivity of a patient to externally applied vibration. The device includes a pallometer head which supports a vibratable probe. The probe is caused to vibrate with a selected amplitude and at a selected frequency. The head is supported beneath a table with the probe extending through an opening in the table so that the probe can be engaged by a member of the patient as the member rests on the table. The head is supported on a beam which carries a counterweight so that the probe engages a member of the patient with a controlled pressure.
