This disorder has also been called exercise induced collapse (EIC), exercise induced hyperthermia, stress seizures and "the wobbles". The patient should not be walked backwards (ie, reverse wheel barrowing). The loss of an animal's sense of touch or ability to feel pain suggests moderate to severe spinal cord damage. This evaluation requires some knowledge of the patients normal behavior. Localize the lesion (ie, make a neuroanatomical diagnosis). Other tests may be used in some cases. Note the contrast enhancement of the right lateral aspect of the medulla (red arrow). Postural reaction deficits are the most important indicator of central disease; and deficits in cranial nerve V to XII are the most likely.2 Patients with paradoxical vestibular disease typically exhibit normal mentation, ipsilateral hypermetria, cerebellar ataxia and ipsilateral proprioceptive deficiencies but no other cranial nerve deficits (except occasionally a menace deficit); these patients exhibit a contralateral head tilt and lean opposite the side of the lesion.3 A more complete guide to individual areas of testing and their neuroanatomic localization can be found in TABLE 1. Heart rate: Typically elevated in both dogs and cats at the beginning of most critical illnesses (may also be stress related from being in the hospital).
