چکیده
Carr, Jennifer G. M.S., Purdue University, August 2014. Cut-off Values for Gait Variables to Detect Forelimb Lameness in Individual dogs. Major Professor: Gert Breur. The objective of this study was to characterize kinetic and kinematic variables in dogs with forelimb lameness and determine lameness cut-off 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 cut-off value for PVF and %WD were ≤ 10.6 kgf (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.

Inertial sensor-based system for lameness detection in trotting dogs with induced lameness.
Lameness detection can be challenging in dogs, as reflected in the reported low inter-rater agreement when visually assessing lameness. The aim of this study was to use an inertial sensor-based system to detect and quantify induced distal and proximal limb disturbances mimicking supporting and swinging limb lameness in dogs trotting on a treadmill by measuring vertical head and pelvic movement ...

Objective measures of canine gait quality via force plates, pressure mats or kinematic analysis are considered superior to subjective gait assessment (SGA). Despite research demonstrating that SGA does not accurately detect subtle lameness, it remains the most commonly performed diagnostic test for detecting lameness in dogs. This is largely because the financial, temporal and spatial requireme...
