Sensory evaluation is generally performed last. The animals response to both pressure (hyperpathia) and pin prick stimuli (sensory level) applied to along the spinal column musculature may help localize the lesion. Application of painful stimuli to each limb and the tail (deep pain perception) should elicit a behavioral response (e.g., vocalization, turns to look or bite, or attempts to get away from the examiner) indication the presence of sensation.
