“…Although the pressure measurement in the present study had a high spatial (2.6 sensors/cm 2 ) and temporal resolution (up to 500 Hz), this variability could be due to limitations in the dynamic response to loading and unloading of the multitude of activated sensors and is more likely to affect the calculation of pressure (which is force per unit of area) than the vertical force alone. This confirmed the higher relevance of PVF and VI in equine gait evaluation (Ishihara et al, 2005) as for routine use in a clinical setting repeatability of measurements is crucial.…”

“…The range of velocity at the trot was set similar to those used by Ishihara et al (2005) and Perino et al (2007). At walk, an even more narrow range was set, to minimise inter-trial variability.…”

“…The most relevant kinetic parameters in equine gait evaluation are peak vertical force (PVF) and vertical impulse (VI), which is the area under the force curve (Ishihara et al, 2005). However, the use of force plate technology in horses is largely limited to experimental settings, mainly because forces created by different limbs simultaneously in contact with the plate cannot be separated, and the limited force plate dimensions preclude recording consecutive strides.…”

a b s t r a c tSubtle lameness in horses may be difficult to diagnose and methods to evaluate lameness objectively are useful when equine clinicians fail to reach a consensus. The aim of this study was to determine whether equine pressure plate measurements are repeatable when used to calculate forelimb loading (peak vertical pressure [PVP], peak vertical force [PVF], vertical impulse [VI]) and symmetry ratios, and to establish if these data are similar to the 'gold standard' force plate values. Since plate dimensions are relatively small, ponies were used to enable recordings to be taken from both forelimbs in one trial. Five sound ponies were walked and trotted over a pressure plate which was embedded in a custom-made runway. For each pony, five valid trials were recorded during two different days. A trial was considered valid if complete prints of both fore hooves were recorded consecutively and if velocity was within a preset range.The PVP, PVF and VI values showed an acceptable variability (CV 6 16%), with PVF (130% of bodyweight [BW], n = 5) similar to previously reported force plate data (128% BW, n = 48). Mean symmetry ratios appeared to be high (>95%) and showed a low variability (CV < 5%). The stand-alone pressure plate permitted adequate registration of forelimb PVF, VI and limb symmetry with a high level of precision in sound ponies.

“…However, these temporal variables may not be useful kinetic parameters with which to predict equine gait anomalies, due to the rather large inter-individual variability and low sensitivity for detection of mild lameness (Ishihara et al, 2005). The observed differences in PVF and VI symmetry ratios (2-7%; Table 1) were relatively small, whilst excellent agreement between PP and FP symmetry ratios was identified.…”

a b s t r a c tModern pressure plates (PP) could be an alternative to traditional force plates (FP) for quantitative equine gait analysis, thereby providing the clinician with objective data on the horse's gait while unravelling the loading of different regions of the hoof during the stance phase. The aim of this study was to determine whether a stand-alone PP allows reliable measurement of gait kinetics, compared to simultaneously recorded FP variables. Six sound Warmblood horses were walked and trotted over a combined PP and FP system for collection of a set of five valid kinetic measurements for each forelimb. A measurement was considered valid if the horse was moving in a straight line at a constant pace while gait velocity was within a preset range and the hoof fully contacted the plate surface.Significant differences between FP and PP data were seen for peak vertical force (PVF), vertical impulse (VI), time at which the PVF occurs (tPVF) and forelimb symmetry ratios (SymPVF and SymVI) (P < 0.05), but not for stance phase duration (ST). Nevertheless, mean agreement indices (AIs) of ST, tPVF and SymP-VF and SymVI were excellent (P0.92), whereas AIs of PVF and VI were moderate (P0.70). The excellent agreement between PP and FP symmetry ratios confirms that observed differences between PP and FP in symmetry ratios are small (2-7%), especially when compared to the expected decrease in symmetry associated with mild lameness (>20%). The results indicate that a stand-alone pressure plate can be used to measure absolute (ST) and relative (tPVF) temporal variables and loading symmetry ratios and offers equine veterinarians a mobile, cost-efficient and quick gait evaluation method for routine clinical use. However, the system cannot be used interchangeably with a force plate to measure absolute values of limb loading.

Abstract: Among the kinetic gait parameters, vertical force peak and impulse had the best potential to reflect lameness severity and identify subclinical forelimb gait abnormalities.
