The pressure walkway system also ealled pressure sensors system, most were designed to measure spatio-temporal gait analysis and built around pressure sensors included in a walkway. Data collection and analysis was performed by specific software. Pressure walkway was used recently in some research for humans [3], but still very little in animals such as dogs [4, 5], cats [1, 2], rat [6] and sheep [7]. 

Our results were collected from 12 of 22 client-owned cats by encouraging them to walk freely across a pressure walkway.

But in the previous study of LeQuang et al. 2009 using the pressure walkway, which very similar to the one used in this study, for healthy large-breed dog, the ratio fore/hind limb of stance time relative and peak vertical pressure were 1.10 and 1.47, respectively [4]. In another report using the pressure walkway also in normal Greyhound, this ratio for peak vertical force was 1.38 [5] and for the healthy sheep, body weight distribution was 59% for the forelimb [7]. The stance distribution in cat was less importance than in dog and sheep.

Standard shapes for composite stiffeners are not likely to occur for most aerospace applications. There, the value and function of the structure warrant optimizing the stiffener design. In contrast, for more everyday applications such as scaffolding, stairways, and walkways in chemical plants, competitive pressures lead to a situation where compromises in stiffener efficiency are readily accepted (overdesign) in order to achieve lower cost than would be associated with optimum design.

The 3-D ground reaction force vector, the vertical ground reaction torque and the point of application of the ground reaction force vector (i.e., center of pressure) are measured with force platforms embedded in the walkway. Force plates with typical measurement surface dimensions of 0.5 x 0.5 m are comprised of several strain gauges or piezoelectric sensor arrays rigidly mounted together. 

Miraculously, aU but one of the six workers eso5)ed the lower chamber. The skth employee was killed by massive blunt trauma to the head and upper torso. The confined space attendant was caught in (he releasing nitrogen pressure and was pushed through the guardrail of the walkway he was standing on. He was killed instantly.

The purpose of this prospective study was to evalrrate spatio-temporal and pressure parameters in two different sized dogs healthy large-breed and small-breed dogs, by using a 4.3 meter pressure sensors walkway.
