Hoof Explorer: Discover and Interact with the Horse's Foot in Three Beautiful Dimensions, Online

Hoof Explorer is a new interactive 3-D anatomy education tool that is in four languages and has almost infinite capacity for displaying the anatomy of the distal limb.

It's official: 2013 is the year of 3-D hoof anatomy on the web. 

Online Veterinary Anatomy Museum Injects High-Tech Media & Movement into the Study of Equine Structure

What's your vision of an anatomy museum? Giant paintings on the walls? A sculpture of a hoof? Think again! The foot in this photo is from a 3-D movable program that is one of the showpieces of the new Online Veterinary Anatomy Museum. (Larger image © Hoofcare Publishing)

An anatomy museum is a wonderful place. But who among us can travel to Harvard's Museum of Comparative Zoology or to London's Natural History Museum when we feel like studying anatomy?

If we can't go to the museum, can the museum come to us?

Guess what? It already has.

Science of the Olympics: Sport Analysis Videos to Inspire Your Thoughts on Horses

Note: NBC Olympics videos have an annoying auto-play function so the videos have been moved off the blog. Please go to "Science of the Summer Olympics: Engineering In Sports", a 10-part video series produced in partnership with NBC Learn to view the videos described in this blog post.

Have you been staring at a television screen, immersed in the Olympics? Are you chewing your nails for the Swiss beach volleyball team or the Luxembourg table tennis team? Do you wonder if they ever really will get back to Greenwich Park and the equestrian events?

We get wrapped up in the competition of sports but the Olympics is a good time to remember that the same sport science that is used to advance horse sports and hoof science is also used on human athletes.

So whether you are Usain Bolt or Zenyatta, there's a professor at MIT who can dissect your stride. And the same terminology is used whether you're measuring the stride of a track star or a Thoroughbred.

   

How can we get BMW interested in horses? In order to maximize his performance in the decathalon, 2008 Olympic gold medalist Bryan Clay teamed up with engineers from BMW to improve measurement of the horizontal and vertical velocities of his long jumps.

Could the same long-jump technique be used to analyze how Kauto Star won the Cheltenham Gold Cup or how a rider like Meredith Michaels-Beerbaum's horse will clear the water jump at Greenwich Park this weekend?

While you're watching the Olympics, think about the fact that the emerging gait analysis and sport science we see used in horse sports is being applied to each and every one of those Olympic sports. In some aspects, horse sports have lead the way. In other aspects, horse sports have a lot of catching up to do.

So don't think for a minute that you're wasting time watching the Olympics. You're doing your homework, albeit on the subconscious level in many instances. Some creative thoughts about how horses move are sure to pop into your head a week or two from now, and you'll wonder where those thoughts originated.

Maybe you'll never see a horse on a balance beam, but when you think about the pressure to always improve the level of performance while not crossing the line to injury, you realize that all athletes have a lot in common, whether they're horse or human.

These two sample videos are part of "Science of the Summer Olympics: Engineering In Sports", a 10-part video series produced in partnership with NBC Learn. (You can watch them all online and if you're really interested or if you know a teacher who might be, there are lesson plans available to use these videos in the classroom. Just pretend the humans are horses.)

Australian Anatomy Animation: Tendons and Ligaments of the Distal Limb

by Fran Jurga | 9 June 2009 | Fran Jurga's Hoof Blog

People make a lot of jokes about "boning" up on their equine anatomy knowledge, but Australian researcher Jonathan Merritt took it to heart and dedicated himself to creating a three-dimensional model of the lower limb of the horse, on which he has applied the ligaments that hold the entire apparatus together and the tendons that move its parts. He applied them layer by layer so that you can see the enormous complexity of the segmented structure of the equine limb.

The technical definition of a ligament is an attachment between two bones; generally a ligament is in a position that will make use of its fibruous strength in just the right place and angle to stabilize a joint. Ligaments allow flexion, but prevent malfunction. Tendons, of course, are extensions of the muscles in the upper limb that move the joints in the lower limb.

Jonathan Merritt's PhD thesis at the University of Melbourne was on the biomechanics of the forelimb of the horse. The focus of the research has been the relationship between the dynamics of locomotion and the strains induced in the third metacarpal bone. Dr. Merritt's work includes being lead researcher in the study Influence of Muscle-Tendon Wrapping on Calculations of Joint Reaction Forces in the Equine Distal Forelimb in the Journal of Biomedicine and Biotechnology (Click here to read online.)

Here's his description of how the little video was made: "The models of the bones were created from real equine limb bones using in-house photogrammetric software that I wrote. The bones were imported into Blender, and the ligaments and tendons were modeled by hand. Finally, a custom RenderMan exporter script was used to export the models and camera animations to the Aqsis renderer."

Dr. Merritt has been very generous to post this video and others he's made both on YouTube and vimeo.com.

I don't know that you can or should download it and hope that no one will abuse his generosity in both posting the videos and allowing them to be seen in places like this blog. The right thing to do would be to bookmark the video, send others to watch it and send an email to him letting him know you appreciated his hard work.

Encouraging talented people like Dr Merritt to pursue further studies in equine biomechanics and anatomy would benefit us all. Thanking generous people like him can't be done often enough.

Best of 2008: A Class Act at the McPhail Center's Equinology Gait Seminar

by Fran Jurga | 29 December 2008 | Fran Jurga's Hoof Blog

I had a wild plan and approached Dr. Hilary Clayton of Michigan State University's McPhail Center for Equine Performance with my proposal: a camp for professional at her research center, where we could learn about high-tech gait analysis and help her with a research project.

With her usual British chipper nonchalance, she replied. "Ok, come in October then. It's already in the works." The Equinology group had a course planned at the McPhail Center and it was to be open to equine professionals in search of a deeper exposure to the high-tech side of equine biomechanics.

As it turned out, I wasn't able to be there, but Sarah Miles provided a wonderful report, from which these comments are taken:

The McPhail Center, located at the College of Veterinary Medicine at Michigan State University in East Lansing, is one of the few university labs designed expressly for studying equine biomechanics. It is a fantastic facility — our classroom looked into the covered riding arena where research staff and students collect data with the horses.

When Dr. Clayton dramatically lifted the curtains on the riding arena the first day, a collective gasp of awe went up from the group. She told us that the building's vaulted ceiling design actually is borrowed from church architecture, so we really were having a religious experience, of sorts! But perhaps that explains the sense of “entering the inner sanctum” that one gets from learning from this world-renowned equine biomechanics expert and her staff and students in the lab designed just for their research.

Of course, what is really interesting about the arena is primarily along one side, where eight infrared video cameras collect data from horses lit like Christmas trees (Dr. Clayton’s words), as their anatomical markers move through the cameras’ shimmering red field of vision. It is one thing to hear Dr. Clayton describe the process of research and data collection, and another to experience it for yourself.

Horses' joints are marked with photosensitive styrofoam balls that will light up under infrared camera exposure. (McPhail Center photo courtesy of Dr Hilary Clayton)

The end result of the gait analysis is a stick-horse animation showing the horse in motion on the computer screen. A further sophistication of this system creates a 3D rendering. (McPhail Center photo courtesy of Dr Hilary Clayton)

Dr. Narelle Stubbs, the equine physiotherapist who co-wrote Activate Your Horse’s Core with Dr. Clayton and lab manager LeeAnn Kaiser helped us to tape all the markers on the horse in the right spots. LeeAnn showed us how they calibrate the cameras, create a template, collect the data, connect the dots, and generate three-dimensional computer animation of the horse in motion. The data is also logged into spreadsheets and analyzed for the results of any given project. Dr. Clayton explained that this technology is very similar to how they created “Golem” in Lord of the Rings.

A lecture by Dr. Clayton on the function of the stifle offered her untested hypothesis (stemming from the fact that the torque on the stifle joint is in the back of the joint) that the horse’s hamstring muscles are more important in the action of the stifle than the quads. Her thinking on this was that dressage horses are asked to work as though they are “sitting.” A student with experience in ballet volunteered the ballerina's plie support system of standing on the toes while engaging the hamstrings and adductors so that the quads are more relaxed and not the sole source of support. He even demonstrated the plie for the class!

In this research project, a rider's rein tension in measured. Rein tension can be compared between riders or to understand how different bits or the components of a bridle and reins are working. (McPhail Center photo courtesy of Dr Hilary Clayton)

Other highlights of the course included how the force plates work, and a riding demonstration of an electronic pad placed beneath the saddle to measure the pressure it puts on the horse’s back as he performs different activities, and an afternoon spent practicing core mobilization and strengthening exercises for horses with Dr. Stubbs.

The winter edition of this Equinology course is held at Writtle College in England in January and is sold out. Equinology’s next USA course, Biomechanics and Gait Analysis (EQ300MSU), with Dr. Clayton at The McPhail Center will be held October 12-15, 2009. An understanding of basic anatomic and veterinary vocabulary is a prerequisite for this class. Visit www.equinology.com for more information.
