“…For example, Rajkondawar et al (2002) proposed that force plate systems could be installed on dairy farms and used as a tool to detect cows with hoof injuries, and Herlin and Drevemo (1997) used kinematic techniques to evaluate the long-term influence of management systems on the locomotion of dairy cows.…”

Lameness is one of the most important dairy cow welfare issues and has inspired a growing body of literature on gait assessment. Validation studies have shown that several methods of gait assessment are able to successfully distinguish cows with and without painful pathologies. While subjective methods provide an immediate, on-site assessment and require no technical equipment, they show variation in observer reliability. On the other hand, objective methods of gait assessment provide accurate and reliable data, but typically require sophisticated technology, limiting their use on farms. In this critical review, we evaluate gait assessment methods, discuss the reliability and validity of measures used to date, and point to areas where new research is needed. We show how gait can be affected by hoof and leg pathologies, treatment of these ailments and the pain associated with lameness. We also discuss how cow (e.g. conformation, size and udder fill) and environmental features (e.g. flooring) contribute to variation in the way cows walk. An understanding of all these factors is important to avoid misclassifying of cows and confounding comparisons between herds.

“…The kinetic approach was mentioned ten times (33% of 30 mentions). Locomotion scoring was done either by measuring forces exerted on the floor surface by the hoofs while cows walked on two parallel force plates (Rajkondawar et al, 2002;Rajkondawar et al, 2006), or by measuring changes in weight distribution while cows stood on a platform containing four independent weight recording units (Pastell et al, 2008;Pastell et al, 2010).…”

“…The kinetic ALSS first described by Rajkondawar et al (2002), uses different ground reaction forces and stance time of individual limbs (Tables 3 and 4). The kinetic ALSS using four independent weighing units as sensors described by Pastell and Kujala (2007), measures the weight distribution among limbs when the cow is standing.…”

“…In an earlier work we addressed modeling of bovine lameness, and we used logistic regression to evaluate lameness predictions of dairy cattle (Rajkondawar et al, 2002). In the current manuscript, logistic regression models (Hosmer and Lemeshaw, 2000) are used to predict the probability that an examined rat belongs to the SOD1-G93A mutant group in terms of the LPs.…”
