Instrumented hoof boot shows promise for objective gait analysis

A research team at the University of Veterinary Medicine Hannover is pushing objective equine gait analysis closer to field and clinic use with a novel instrumented hoof boot that combines pressure sensors and an inertial measurement unit. The study featured in Equine Veterinary Journal snippets validated the boot against force plate gait kinetics in horses at walk and trot, addressing a longstanding gap between gold-standard biomechanics tools and what most equine practices can realistically use day to day.

That gap matters because force plates are widely regarded as the gold standard for measuring ground reaction forces in lameness workups, but they’re expensive, stationary, and typically limited to referral hospitals or research environments. Wearable inertial systems have become more common in equine practice because they’re portable and can quantify movement asymmetry, but reviews of the field note that kinetics, especially hoof-level force data, have been much harder to capture outside controlled settings. Earlier studies have explored hoof-mounted IMUs and in-shoe pressure systems, but each came with practical or accuracy limitations. (equimanagement.com)

According to reporting from the 2025 AAEP Convention, the Hannover group’s first validation study enrolled 27 non-lame horses and recorded data from the instrumented hoof boot and runway-embedded force plates simultaneously at the walk and trot. Florian Geburek told attendees there was a high correlation between hoof pressure measured by the boot and vertical ground reaction force measured by the force plates. The team also reported that the boot’s integrated IMU could distinguish stance-phase subphases, including landing, midstance, and breakover, on hard ground at both gaits. That matters because subtle changes in breakover may help flag early locomotor problems before overt lameness is obvious. (equimanagement.com)

The project appears to be broader than a single validation experiment. Hannover’s 2024 research report describes an ongoing program, running from May 2023 through the end of 2025, focused on validating and clinically applying a hoof boot equipped with pressure sensors and an IMU in horses. The report says the system is being compared with established kinetic methods, including pressure or force plate testing, and with kinematic approaches such as the Equinosis Lameness Locator. It also notes industry funding totaling €196,665, reflecting active commercial interest in wearable gait tools. (tiho-hannover.de)

There’s also early evidence that the platform may have clinical utility beyond validation in sound horses. A 2026 Veterinary Journal paper from Jasmin Keller and colleagues evaluated 26 horses undergoing lameness examination and found significant differences in peak vertical pressure and impulse between lame and contralateral limbs before positive diagnostic anaesthesia, but not after. The authors concluded the instrumented hoof boot was generally suitable for detecting limb differences and for monitoring the effect of diagnostic anaesthesia through more symmetrical post-block loading patterns. The same paper disclosed funding and equipment support from ContiTech Deutschland GmbH, an important detail for readers weighing translational promise against potential conflicts.

Industry-facing coverage has been notably optimistic. EquiManagement reported that the boot has “high potential” for early lameness recognition and highlighted the ability to assess asymmetry not only at the trot, but also at the walk. That’s consistent with broader literature suggesting wearable inertial technologies can improve objective locomotion assessment, although the strongest evidence still tends to come from controlled studies rather than routine ambulatory practice. In other words, the direction of travel is clear, but the evidence base is still maturing. (equimanagement.com)

Why it matters: For equine veterinarians, this is less about a gadget story and more about workflow. If hoof-mounted sensors can reliably capture kinetic data in a portable format, they could help bridge the gap between subjective lameness exams and lab-grade force plate analysis. That could be especially useful for early or mild asymmetries, response-to-block assessment, longitudinal monitoring, and cases where pet parents want clearer objective evidence of change over time. It may also complement, rather than replace, existing IMU-based asymmetry systems by adding hoof-level loading information to motion data. Still, clinicians should keep the caveats in view: the published lameness-monitoring study involved a relatively small and mixed population, speed was not standardized, diagnoses varied, and broader validation across surfaces, shoeing conditions, and practice environments is still needed.

What to watch: The next milestones are likely full peer-reviewed publication of the force plate validation study, more data on performance in real clinical populations and varied footing, and signs of commercialization or wider practice adoption as the Hannover project reaches its stated end date of late 2025.
