Automatic hoof-on and -off detection in horses using hoof-mounted inertial measurement unit sensors

M. Tijssen , E. Hernlund, M. Rhodin, S. Bosch, J. P. Voskamp, M. Nielen, F. M. Serra Braganςa, June 3, 2020, PLOS ONE, https://doi.org/10.1371/journal.pone.0233266    For gait classification, hoof-on and hoof-off events are fundamental locomotion characteristics of interest. These events can be measured with inertial measurement units (IMUs) which measure the acceleration and angular velocity in three directions. The aim of this

Variation in gait parameters used for objective lameness assessment in sound horses at the trot on the straight line and the lunge

A. M. Hardeman, F. M. Serra Bragança, J. H. Swagemakers, P. R. van Weeren, L. Roepstorff. Equine Veterinary Journal  ISSN 2042-3306 (2019), DOI: 10.1111/evj.13075    Objective lameness assessment is gaining more importance in a clinical setting, necessitating availability of reference values. The objective is to investigate the between ‐path, ‐trial and ‐day variation, between and within horses, in the locomotion symmetry of horses in regular use

On the brink of daily clinical application of objective gait analysis: What evidence do we have so far from studies using an induced lameness model?

F.M.Serra Bragança, M.Rhodin, P.R.van Weeren (2018), The Veterinary Journal Volume 234, April 2018, Pages 11-23    Quantitative gait analysis has the potential to offer objective and unbiased gait information that can assist clinical decision-making. In recent years, a growing number of gait analysis systems have come onto the market, highlighting the demand for such technology in equine orthopaedics. However, it is imperative that
