Fig. 2. Tarlov scores were used to evaluate the motor function in each individual rabbit 2 and 7 d after 30-min spinal cord ischemia. The comparisons were made, and P values among groups are presented. O = animals that survived 2 days; Õ= animals that survived 7 days. Tarlov score: 0 = paraplegic with no lower extremity motor function, muscle tone, or contraction; 1 = poor lower extremity motor function, weak antigravity movement only; 2 = some lower extremity function with good antigravity strength but inability to draw legs under body; 3 = ability to draw legs under body and hop, but not normal; 4 = normal. We did not assess animals that survived 1 day. Day 2 assessments were unchanged in animals that survived 7 days.
