Journal Article
Horan, K., Kourdache, K., Coburn, J., Day, P., Carnall, H., Harborne, D., Brinkley, L., Hammond, L., Millard, S., Lancaster, B., & Pfau, T. (2021). The effect of horseshoes and surfaces on horse and rider centre of mass displacements at gallop. PLoS ONE, https://doi.org/10.1371/journal.pone.0257820

Horseshoes influence how horses’ hooves interact with different ground surfaces, during the impact, loading and push-off phases of a stride cycle. Consequently, they impact on the biomechanics of horses’ proximal limb segments and upper body. By impl...

Visual evaluation of hindlimb lameness in the horse is challenging. Objective measurements, simultaneous to visual assessment, are used increasingly to aid clinical decision making. The aim of this study was to investigate the association of pelvic m...

How low can we go? Influence of sample rate on equine pelvic displacement calculated from inertial sensor data (2020)
Journal Article
Pfau, T., & Reilly, P. (2020). How low can we go? Influence of sample rate on equine pelvic displacement calculated from inertial sensor data. Equine Veterinary Journal, https://doi.org/10.1111/evj.13371

Background

Low‐cost sensor devices are often limited in terms of sample rate. Based on signal periodicity, the Nyquist theorem allows determining the minimum theoretical sample rate required to adequately capture cyclical events, such as pelvic mo...

Quantitative gait analysis in horses is rapidly gaining importance, both clinically and in research. The number of available systems is increasing, but the methods of signal analysis differ between systems and research groups. Our objectives are to d...

The effect that induced rider asymmetry has on equine locomotion and the range of motion of the thoracolumbar spine when ridden in rising trot (2020)
Journal Article

The effect that induced rider asymmetry has on equine locomotion and the range of motion of the thoracolumbar spine when ridden in rising trot. Journal of Equine Veterinary Science, 88, https://doi.org/10.1016/j.jevs.2020.102946

There is a paucity of evidence on the effect that rider asymmetry has on equine locomotion. The aim of this study was to evaluate the effect of rider asymmetry on equine locomotion by using a novel approach to induce rider asymmetry. Ten non-lame hor...

Objective gait monitoring is increasingly accessible to trainers. A more comprehensive understanding of ‘normal’ gait adaptations is required. Forty two-year-old thoroughbred racehorses were recruited when entering training and followed for 22 months...
