Protracted walking problems among hip surgery patients

People who have undergone hip surgery with total hip arthroplasty often experience no difficulty in walking – but for some, mobility actually is impaired long after surgery. Research under way at Sahlgrenska Academy is ...

Bayesian method useful for noncompleters of 400-m walk

(HealthDay)—A Bayesian multiple imputation (MI) method is useful for calculating the speeds of those who are unable to complete the 400-m walk test within the time constraint (noncompleters), according to a study published ...

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.
