“…Considering the similarity between the regression formulas of SPD-F and SPD-H with respect to speed, the formulation of a merged and simplified equation is understandable. SPD-F is practically equal to SPD-H and decreases with increasing speed, which is in accordance with the results of other studies [36,37]. SPD of forelimbs and hindlimbs almost decreased exponentially with speed according to our study.…”

Ground reaction force and impulse measurement is an established method for assessing the physical condition and efficacy of treatment for some animals. The primary aim of this study was to quantify the kinetic parameters of the limbs of healthy cats at different speeds. The second aim was to determine the explicit relationship between the kinetic parameters and speed. Peak vertical force (PVF), vertical impulse (VI), stance phase duration (SPD), and paw contact area (PCA) of each limb (forelimb, F; hindlimb, H) of seven clinically healthy, client-owned cats were recorded in the speed interval of 0.5–2.5 m/s. The cats were encouraged to pass by a pressure-sensitive walkway with different speeds. The results revealed that there were no significant differences in any of the tested parameters between the left and right forelimbs and the left and right hindlimbs. Means and regression formulas of the kinetic parameters with speed were obtained. It was evident that PVF-F and PVF-H increased linearly with speed, while VI-F and VI-H decreased exponentially. SPD-F was practically equal to SPD-H and exponentially decreased with speed. PCA-F increased linearly with speed, and PCA-H was almost invariable. Pressure-sensitive walkway is a suitable and convenient equipment for assessing the kinetic parameters of cats. Variation of these kinetic parameters with speed can be explained by the functional difference for forelimb-dominant and hindlimb-driven.

“…P ressure-sensitive walkway (PSW) systems have been growing in popularity as an effective and convenient way to objectively assess canine, feline, and equine gait patterns in clinical and research settings. [1][2][3][4][5][6][7][8] Several PSW systems have been validated for assessment of temporospatial gait variables including, but not limited to, gait time, distance, velocity, cadence, and cycle time. Additionally, PSW systems are able to measure ground reaction forces (GRFs), including percentage of body weight placed on each limb, impulse (percentage of body weight times seconds), and maximum force exerted on each limb both as a percentage of body weight and as an absolute value.…”

OBJECTIVE To determine whether use of a protective cover would affect temporospatial gait or ground reaction force (GRF) measurements obtained from dogs walking on a validated pressure-sensitive walkway (PSW). ANIMALS 5 healthy dogs. PROCEDURES In a crossover study design, all dogs were walked across a calibrated PSW with and without a protective cover in place in random order. Temporospatial gait data and GRFs obtained with and without the cover in place were compared. RESULTS No significant differences were identified in temporospatial gait measurements obtained with versus without the cover in place. The bias was low for all variables, and the 95% limits of agreement included 0. In contrast, significant differences were found between measurements obtained with versus without the cover in place for most GRFs, with measurements obtained with the cover in place significantly lower than those obtained without a cover. CLINICAL RELEVANCE Results suggested that for dogs walking over a PSW, GRFs, but not temporospatial gait variables, would be significantly lower if a protective cover was placed over the walkway, compared with values obtained without a cover in place.
