“…However, this was also applicable for the trailing limb [6]. Another study by Wang et al in humans, investigating the effect of the distance between two obstacles by using force plate, revealed that the foot integrated pressure (equivalent to IFz) was significantly higher in the leading limb than the trailing limb when the distance between two obstacles was one step [10]. Further research is warranted to investigate if walking over obstacles can influence the IFz in dogs with orthopedic diseases, where this value is reduced [24].…”

“…The changes observed for the leading limb regarding forces and force-time characteristics were a result of not only landing after an obstacle but also controlling the trailing limb over obstacles [6]. Furthermore, when walking over two obstacles, the trailing limb must overcome two obstacles; thus, the swing phase of this limb may be longer than that of the leading limb that must overcome just one obstacle [10]. In a human study, it was observed that subjects spent a longer time on the leading limb than the trailing limb during obstacle crossing [45].…”

“…Kinematic and kinetic measurements have been used in order to investigate the influence of obstacle crossing in humans [5,6,10]. In dogs, researchers investigated the impact of cavaletti rails on the ROM of healthy [11] and diseased [3,12] dogs and on the activation of specific muscles through electromyography (EMG) [13,14] but not on the kinetics.…”

Walking over obstacles is a widely used physiotherapy exercise in dogs. Current research is limited to the effect of this exercise in kinematics and muscle activation in dogs. The present study assessed the influence of walking over obstacles on the ground reaction forces (GRFs) and center of pressure (COP) in dogs. Data of dogs walking over one and two obstacles over a pressure platform were retrospectively analyzed and compared to normal walking. Walking over one obstacle did not affect the GRFs and COP of the forelimbs; however, significant changes were observed for the hindlimbs, especially the leading hindlimb. Walking over two obstacles caused significant changes to only one value at the forelimbs, whereas multiple significant changes in the GRFs and COP values were observed at the hindlimbs. Walking over obstacles seems to be challenging even for healthy adult dogs. Further studies are needed to investigate how different heights of obstacles and distances between them can further challenge the animals. The combination of kinetics and kinematics during walking over obstacles may be used in future as a diagnostic tool in geriatric and neurological patients in order to assess their proprioception awareness or to assess the improvement after an intervention, e.g., physiotherapy treatment.

Multiple obstacle avoidance induces a higher potential of falls among older adults. This study attempted to add other important measurements by investigating the pressure-related gait parameters when stepping over multiple obstacles on a portable pressure-sensing walkway. Twenty-six young and 26 older participants were recruited in this study. A portable pressure-sensing Zeno walkway and cyclogram intersection point analysis method was introduced to collect both spatial–temporal and pressure-related gait parameters. Older adults significantly reduced foot integrated pressure of the leading leg when stepping over the second obstacle compared with young adults (p = .0078). A significantly larger cyclogram intersection point shift in medial–lateral direction was found in older adults than in young adults (p = .024) when stepping over the second obstacle, especially in the lateral direction. The results of this study showed that a pressure-sensing walking combined with cyclogram intersection point method could detect foot pressure distribution differences caused by aging.
