Postural reactions decreased to absent in all four limbs or in ipsilateral thoracic and pelvic limbs. Proprioceptive ataxia affecting all four limbs equally. Neurogenic atrophy in ipsilateral or bilateral thoracic limbs disuse atrophy in pelvic limbs Reduced to absent in thoracic limbs normal to increased in pelvic limbs Reduced to absent ipsilaterally or bilaterally in the thoracic limbs intact (normal to increased) in pelvic limbs reduction or loss of cutaneous trunci reflex with C8, T1 lesions Intact (normal to increased) in all four limbs Tetraparesis, tetraplegia, hemiparesis, hemiplegia, monoparesis, monoplegia Tetraparesis, tetraplegia, hemiparesis, hemiplegia Very rare positional strabismus and/or facial hypesthesia with C1-C3 lesions Normal may be difficult to assess if the condition is painful 216Ĭlinical Signs Manifested by a Focal Lesion Affecting the Cervical Spinal Cord Clinical signs of intracranial disease, in addition to the aforementioned signs, suggest a multifocal disease process or a focal brainstem disease. ![]() Most spinal cord diseases will result in varying degrees of abnormality of both movement and sensation because the neuroanatomic pathways responsible for these properties are adjacent to each other. Use of these five groups can help the clinician to accurately localize the neurologic lesion ( Table 31-1). 141 An animal with spinal cord disease can display clinical signs as described in the following five groups: (1) reduction or loss of voluntary movement, (2) spinal reflex abnormalities, (3) alterations in muscle tone, (4) muscle atrophy, and (5) sensory dysfunction. Observation of an animal’s gait, posture, and mentation, in addition to examination of postural reactions, spinal reflexes, cranial nerve function, and state of consciousness, is necessary to confirm the presence of spinal cord disease these tests will also assist with accurate lesion localization and in determination of whether a focal, multifocal, or diffuse disease process is responsible for any abnormalities found.
