Ramp walking helps diagnose lameness in dogs

Gait analysis, pressure walkways, and angled walking are popular techniques used in human medicine. Their use has improved prosthetics, rehabilitation, medicine and more. But, while this research has a long history in human ...

For gait transitions, stability often trumps energy savings

A dog's gait, according to the American Kennel Club, is "the pattern of footsteps at various rates of speed, each distinguished by a particular rhythm and footfall." When dogs trot, for example, the right front leg and the ...

Apple watch monitors falls, track heart rhythms

For more than a decade, the latest Apple products have been the annual must-have holiday gift for the tech-savvy. That raises the question: Is the newest Apple Watch on your list—either to give or receive—this year?

Tokyo Tech's six-legged robots get closer to nature

A study led by researchers at Tokyo Institute of Technology (Tokyo Tech) has uncovered new ways of driving multi-legged robots by means of a two-level controller. The proposed controller uses a network of so-called non-linear ...

Nearly one in three pugs has an abnormal gait

Nearly one in three pugs has an abnormal gait, which in turn is linked to other health issues, finds a Swedish study of owners of the breed, and published online in Vet Record.

Walk this way—a better way to identify gait differences

Biometric-based person recognition methods have been extensively explored for various applications, such as access control, surveillance, and forensics. Biometric verification involves any means by which a person can be uniquely ...

Pressure sensor can identify early stages of flat feet

A team of researchers at Kaunas University of Technology (KTU) have designed a device for measuring pressure on human feet. Its applications include pediatric illnesses and monitoring the physical condition of professional ...

Gait

Gait is the pattern of movement of the limbs of animals, including humans, during locomotion over a solid substrate. Most animals use a variety of gaits, selecting gait based on speed, terrain, the need to maneuver, and energetic efficiency. Different animal species may use different gaits due to differences in anatomy that prevent use of certain gaits, or simply due to evolved innate preferences as a result of habitat differences. While various gaits are given specific names, the complexity of biological systems and interacting with the environment make these distinctions 'fuzzy' at best. Gaits are typically classified according to footfall patterns, but recent studies often prefer definitions based on mechanics. The term typically does not refer to limb-based propulsion through fluid mediums such as water or air, but rather to propulsion across a solid substrate by generating reactive forces against it (which can apply to walking while underwater as well as on land).

Due to the rapidity of animal movement, simple direct observation is rarely sufficient to give any insight into the pattern of limb movement. In spite of early attempts to classify gaits based on footprints or the sound of footfalls, it wasn't until Eadweard Muybridge and Étienne-Jules Marey began taking rapid series of photographs that proper scientific examination of gaits could begin.
