Agneta Egenvall
In focus are health and welfare of horses through their career and usage by man. The aim is to combine epidemiology using big data, biomechanics and ethology in order to elucidate how horses can fare better through their lives and have a longer life. Training methods being a main interest, a dive into biomechanics became needed, as questions in need of answering cannot be well judged from subjective evaluation alone. Secondary databases and other species, as well as evidence-based medicine are also of priority.


Having used insurance data in her research, the continued goal is to enable collection of big data on horses and rider, in order to study management and especially training regimens in relation to health and welfare of horses. We need to know what we look at and look for in data from ‘everyday used sensors’. In the same area, riders will enable performance and/or health to their mounts- thus the multi-facetted rider effect is at focus. Current efforts are mainly put into smaller-scale biomechanical studies to conquer technology and contribute to a framework for data interpretation. Agneta Egenvall is also interested in comparing international pricing of veterinary care.


The main focus of Agneta Egenvall is evidence-based medicine and clinical epidemiology, teaching courses in the veterinary curriculum. This should help the student to find and evaluate evidence or facts, regarding various clinical or nonclinical issues encountered through tuition and careers.


To meet the goals of understanding data signals, research includes high speed video analysis, as well as rein tension, electromyography. Agneta notes that training regimen analysis needs to be multifaceted, because training regimens can vary with a number of dimensions (e.g. from days per week to using shorter or longer reprises for all/certain exercises or in the ‘wisdom’ of the rider to implement a particular kind of exercise/training in response to small signs provided by the horse).


Research keywords are: horse, rider, asymmetry, laterality, horse-rider interaction, lameness, rein tension, surface. Agneta Egenvall currently supervises a project on ‘the give’ during dressage transitions (Marie Eisersiö- same department).


The following themes have been and are being addressed

Rein tension in professional riders with focus on addressing the chaotic signal – be it during the stride or during the riding session.

Transitions between gaits

Asymmetry and lameness of horses

Withers drop asymmetry in walk as a possible laterality indicator

The riders influence on the horse, as well as horse influence on the rider

Rider asymmetries

The rider effect

Characteristics of equestrian surfaces


Epidemiological research demands expertise in many other areas, hence such expertise is frequently sought. The goal of the research is to make the healthy horse stay healthy, the underlying goals being mainly preventative. Agneta Egenvall works together with scientists from universities in Utrecht, Zurich and Michigan as well as with Ridskolan Strömsholm and Livgardets Kavallerikasern.


Egenvall received her veterinary degree from Uppsala in December 1986. She worked clinically in various places for 8 years before entering PhD education in 1994, receiving her PhD degree 2000.


Agneta has supervised 12 post graduate students to fulfilment of PhD, as main supervisor for 5 of them, and about the same number of student works.
