Table 1 The modified functional scoring system used in this study

From: A preliminary evaluation of the reliability of a modified functional scoring system for assessing neurologic function in ambulatory thoracolumbar myelopathy dogs

Each pelvic limb is evaluated individually

1. Non-ambulatory (scores 2–10 indicate the dog is ambulatory and can take at least 4 steps)

2. Weight-bearing protraction of the pelvic limb <10 % of the time

3. Weight-bearing protraction of the pelvic limb 10 to 50 % of the time

4. Weight-bearing protraction of the pelvic limb >50 % of the time

5. Weight-bearing protraction 100 % of the time with reduced strength of the pelvic limb; mistakes >90 % of steps (e.g., scuffing foot on protraction, standing on dorsum of foot)

6. Weight-bearing protraction of the pelvic limb 100 % of the time with reduced strength; mistakes 50 to 90 % of steps

7. Weight-bearing protraction of the pelvic limb 100 % of the time with reduced strength; mistakes <50 % of steps

8. Ataxic pelvic limb gait with normal strength (including ability to rise from a sitting down position); mistakes >90 % of steps (e.g., crossing of pelvic limbs, skipping steps, bunny-hopping, scuffing foot on protraction)

9. Ataxic pelvic limb gait with normal strength; mistakes 50–90 % of steps

10. Almost normal pelvic limb gait with normal strength; mistakes <50 % of steps
