Gait analysis in dogs with pelvic fractures treated conservatively using a pressure-sensing walkway

Abstract

BackgroundThis study aimed to evaluate dogs with pelvic fractures and treated conservatively during locomotion on a pressure-sensing walkway. The hypothesis was that dogs may present changes in kinetic and temporospatial parameters because of the fractures, which may interfere with the symmetry index. Thirty dogs were selected and divided into two groups: Group 1—healthy group (n = 15) and Group 2—conservatively treated group (n = 15). The dogs were of similar body size. The body weight distribution percentages and symmetry indices of the peak vertical force, vertical impulse, stance time, swing time, percentage of stance time, and percentage of swing time of the hind limbs were evaluated.ResultsIn Group 2, the time interval between fracture occurrence and patient evaluation was between 4 and 87 months (mean of 20 months). Four dogs had lower percentage of body weight distribution on one of the hind limbs while three dogs had greater weight distributed toward both hind limbs. Four of these dogs had alterations in the temporospatial and/or kinetic symmetry indices.ConclusionsDogs with pelvic fractures treated conservatively may present changes in percentage of body weight distribution and symmetry indices of the kinetic and temporospatial parameters. The conservative treatment can cause persistent abnormal gait.

Static Posturography: A New Perspective in the Assessment of Lameness in a Canine Model

“…Previous studies describe distribution of force in the pads during the support phase in healthy dogs [6,7] or in dogs with pathologies such as cranial cruciate ligament rupture [8] or hip fractures [9]; the dogs walk or trot across a simple or multiple pressure walkway that provides standard parameters as PVF and VI, usually measured by force platforms. The advantage of this method is that consecutive steps can be recorded; however, research has still not been published on static analysis in lame dogs with postural changes, such as spatial modifications in body center of pressure (COP) and the derived consequences of changes in paw area, and mean or maximum pressure values, among other parameters.…”

Primary surgical repair of prostatic urethral rupture following multiple pelvic fracture in a dog

“…This case report reveals that even a severely displaced ilium fracture can be successfully treated conservatively with appropriate management. Mild persistent lameness was present, as has been described in studies evaluating conservative treatment of pelvic fractures (VASSALO et al, 2015).…”

Comparison of Simultaneously Collected Kinetic Data with Force Plates and a Pressure Walkway

“…As an example, a recent study used cut-off values (average PVF SI þ two times the standard deviation) to distinguish between normal hindlimbs and abnormal hindlimbs with a PM system. 32 It is also interesting to note that different PM systems produce different SI data for healthy dogs. The PM system used in the current study of a heterogeneous population had larger SI and wider standard deviations than a different PM system also examining a heterogeneous population.…”
