Clinical signs	Scoring system
Walking gait	0 — Normal 1 — Perceivable algetic gait 2 — Evident algetic gait
Posture	0 — Normal 1 — Abnormal (perceivable relief) 2 — Abnormal (obvious relief)
Mobility	0 — No limit of motion 1 — Reduction of 10° to 20° of motion 2 — Reduction of 20° to 50° of motion 3 — Reduction of more than 50° of motion
Muscular atrophya	0 — No 1 — Perceptible muscular atrophy 2 — Evident muscular atrophy
Joint pain	0 — No 1 — Slight (complete movement with reluctance) 2 — Moderate (incomplete movement with reluctance) 3 — Severe (no movement allowed)
Visual appreciationb	0 mm Normal 100 mm Severe algetic gait

^aMuscular mass atrophy was assessed by palpation.

^bOn a 100-mm line, the surgeon identified his own appreciation of the algetic gait, the resulting numeral length (score) was further analyzed.

Score for walking gait, trotting gait, posture, mobility, muscular atrophy, and joint pain were added to generate a score for clinical signs.
