Abstract

The aim of this study was to assess the static posturography in dogs as a useful tool for diagnosis of lameness by means of the use of a pressure platform. For this purpose, a series of different parameters (pressure distribution, area of support, mean pressure, maximum pressure and statokinesiograms) were obtained from five lame dogs with unilateral elbow osteoarthritis treated with plasma rich in growth factors. Data were obtained before and 3 months after treatment, and results were compared with a control group of sound dogs of similar conformation. Significant differences were found in the above mentioned parameters between sound and lame limbs. Improvement after 3 months of treatment was also detected, demonstrating that this multi-parametric technique is an effective and reliable method for the assessment of lameness in dogs.

Partial Text

Peak vertical force (PVF) and vertical impulse (VI) are two of the most common kinetic parameters used for lameness detection in dogs, horses and other domestic animal species [1]; these parameters are usually obtained using force [2] or pressure platforms [3–5].

The animals had a mean body weight of 36.88 ± 4.25 kg and a mean age of 5.8 ± 2.04 years.

With static posturography, we were able to determine differences in a set of parameters between lame and sound dogs. Additionally, these differences diminished following treatment, indicating a positive response and thus, effective therapy, as previously published in humans [31].

Based on our results, static posturography was possible to perform in dogs and provided fairly accurate measurements of various parameters not assessed before in the evaluation of forelimb lameness. These parameters, in addition to complement the classic kinetic PVF and VI, may furnish to veterinary practitioners a useful tool to assess asymmetries simultaneously due to COP sway in lame dogs.
