Abstract
BackgroundPedobarographic analyses detect pressure redistribution among limbs and within limbs in humans, equids and dogs. The main objective of this study was to assess the usefulness of a set of pedobarographic parameters for the detection of lameness, as well as for its suitability for assessing the effects of therapies against osteoarthritis in dogs. With this purpose, eleven large-breed lame dogs with unilateral osteoarthritis due to elbow dysplasia were evaluated using a pressure platform prior to (D0) and after 3 months (D90) of treatment with mavacoxib, a COX-2 selective NSAID. The obtained parameters were: pressure distribution between lame and sound limbs, as well as paw area, mean pressure, and peak pressure of both lame and sound limbs.ResultsThe results showed statistical differences in all these parameters between lame and sound limbs at D0; however, at D90, differences were significantly decreased as result of the treatment, indicating a substantial functional recovery under the study design conditions.ConclusionsThe provided data prove the suitability of this novel technique in canine models for the quantitative and objective assessment of lameness, but also for the evaluation of treatments for lameness caused by articular pain.

Pedobarographic analyses detect pressure redistribution among limbs and within limbs in humans, equids and dogs
From the 17 initially included client-owned lame dogs with confirmed unilateral Elbow dysplasia (ED), 3 were discarded due to the inability to remain immobile during postural exam; another dog was unable to walk on the leash properly, and one more due to an alteration in a blood biochemical profile
Data were all normal (p ≥ 0.1) and homoscedastic (p ≥ 0.11).Pressure distribution (PD), Paw area (PA), Mean pressure (MP), and Peak pressure (PP) values in both Lame limb (LL) and Sound limb (SL) showed differences between D0 and day 90 (D90) (p ≤ 0.0001 in all cases), which means an increase in LL values and a consequent decreasing in SL values
Summary
Pedobarographic analyses detect pressure redistribution among limbs and within limbs in humans, equids and dogs. The main objective of this study was to assess the usefulness of a set of pedobarographic parameters for the detection of lameness, as well as for its suitability for assessing the effects of therapies against osteoarthritis in dogs. With this purpose, eleven large-breed lame dogs with unilateral osteoarthritis due to elbow dysplasia were evaluated using a pressure platform prior to (D0) and after 3 months (D90) of treatment with mavacoxib, a COX-2 selective NSAID. This methodology has proven how poor subjective scoring systems are in assessing lameness in dogs [6,7,8,9]
