Abstract

A palpometer device for assisting an examiner to evaluate deep pain sensitivity in a patient includes a housing supporting an axially displaceable spring-biased probe having a proximal end extending from an axial bore in a proximal axial face of the housing, and adapted for abutting contact with the patient. Within the housing, the spring-biased probe incorporates an annular flange for engaging one end of a bias spring coaxially disposed within the housing. The bias spring is disposed coaxially about the probe to resist axial displacement of the housing towards the proximal end of the probe upon manual application of a bias force to the housing, when the proximal end of the probe is in contact with a patient's body.
