Marie Rhodin

Marie Rhodin
I am working as a researcher, clinician (equine orthopaedics) and teacher. My main interest is orthopaedics and clinical biomechanics in horses. I am studying orthopaedic disorders and locomotion in horses in training or during lameness examinations. I also have studies on canine lameness where we transfer knowledge on equine biomechanics.


Marie Rhodin, DVM, associate Professor in equine clinical biomechanics at the department of Anatomy, Physiology and Biochemistry, Swedish University of Agricultural Sciences. She graduated 2003, PhD in 2008 where she studied horse and rider interaction with focus on the effect of different head and neck positions on the kinematics of the back in riding horses. Her main research focus experience in objective motion analysis for lameness detection with techniques as high-speed cameras and inertial measure units. To implement objective measurements in the lameness exams she has looked into the effect of circular movement on movement symmetry in both sound and lame horses. In 2017 she passed the board examination and was accredited as a diplomate of the American College of Veterinary Sports Medicine and Rehabilitation. In 2019 she also become diplomate of the European College of Veterinary Sports Medicine and Rehabilitation. Her main research focus is orthopedic diagnostics, orthopaedic pain and objective motion analysis in horses, horse-rider interaction.



She is teaching veterinary students in anatomy and orthopeadics at the clinic. She is also teaching in anatomy, biomechanics, lameness assessment for students from several programs.


Orthopeadic pain in large animals
Monitoring of motion symmetry in young horses during training
Visual and objective lameness assessment
The effect of lungeing on movement symmetry in horses
Objective lameness assessment in dogs and cows
Comparison of different objective tools for lameness assessment
Motion asymmetry in riding horses- biological variation or lameness?
Movement asymmetries in horses-lameness or laterality?




Marie has research collaborations with Royal Veterinary College, UK, Utrecht University, The Netherlands, Zurich University, Switzerland, Copenhagen University, Denmark, Holar University College, Iceland, NMBU Norway


I am interested in dressage riding and has competed at advanced level.
