Abstract
The objective of this study was to characterize kinetic and kinematic variables in dogs with forelimb lameness and determine lameness cutoff values of gait variables using ROC analysis with observational gait analysis (OGA) as reference. Twenty client-owned dogs with unilateral lameness were included. Dogs underwent orthopedic exam, including OGA, and instrumented gait analysis (IGA; kinetic and kinematic analysis). Kinetic variables with the highest accuracy were PVF and %WD with an area under the curve (AUC) of 0.73 and 0.92, respectively. Optimal cutoff value for PVF and %WD were ≤ 10.6 (sensitivity 70% and specificity 75%) and ≤ 29.7 (sensitivity 90% and specificity 85%), respectively. Results of the ROC analysis indicate that KVs were most useful in determining lameness.
