Introduction

Examination and evaluation of somatosensory function The examination and evaluation of somatosensation requires tests and measures for a variety of sensory modalities. These are often classified as exteroception (superficial sensation), proprioception (deep sensation about the relative position of body segments), and discriminatory sensation (i.e., requiring cortical integration to interpret the meaning of sensory input). A typical classification is listed below.
