Neurologic grading system: grade 1 (cervical hyperesthesia only), grade 2 (mild pelvic limb ataxia or paresis ± thoracic limb involvement), grade 3 (moderate pelvic limb ataxia or paresis ± thoracic limb involvement), grade 4 (marked pelvic limb ataxia or paresis with thoracic limb involvement), grade 5 (tetraparesis with inability to stand or walk without assistance).
