Researchers Build Advanced Mechanical Horse For Therapy

14.05.2009
While hippotherapy works to improve the quality of life for children and adults with physical and mental impairments through riding a horse, just getting some patients onto the horse can be a major obstacle.

But now, Baylor University researchers have built a custom mechanical horse to help those with physical and mental impairments get the same benefit from hippotherapy without having to actually get on to a horse.

“Our vision is that the mechanical horse can provide better access and can act as a complementary tool to actual therapeutic horse riding,” said Dr. Brian Garner, associate professor of mechanical engineering at Baylor and a biomechanics expert. “If the patient is afraid of horses or it may not be safe for the patient to ride a horse, the mechanical horse can act as stepping stone to build the patient up to a level of stability so they can get on to a live horse.”

Garner said hippotherapy is unique and valuable as a therapeutic tool because it produces three-dimensional rhythmic, repetitive movements, which preliminary research has shown simulates the movements of the human pelvis while walking. The movements promote many physical benefits like increased circulation, development of balance and improved coordination among many others. Therapeutic riding can help children and adults with various impairments or delays in development, including those with cerebral palsy, spina bifida, Down syndrome and autism.

Baylor’s prototype mechanical horse mimics a real horse by using a three-dimensional system. The stationary device with a moving saddle surface can move in virtually all directions in a cycling pattern, putting the body through a complex of movements just like real hippotherapy. To make sure the mechanical horse replicates as precisely as possible the movements of an actual horse, Baylor researchers took video-motion photography of several real horses walking and used that data to create the mechanical horses’ movement patterns.

Garner said the mechanical horse also can differ in speed – from a slow walking pace to a fast walking pace – and is the width of a normal horse. It can be used with or without a saddle and can simulate bare-back riding. The saddle also simulates real therapeutic riding saddles that have adjustable handle bars.

“There are some minor problems to fix, but overall the device looks promising,” Garner said.

Garner and his research team will now conduct additional research using the horse, studying the biomechanics of hippotherapy.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
