Walking in horses refers to the natural, four-beat gait characterized by a steady, even rhythm where each hoof hits the ground independently. This gait is fundamental for horses, providing a stable and energy-efficient means of locomotion. Walking is not only essential for the horse's daily activities but also plays a significant role in training, rehabilitation, and overall health maintenance. The mechanics of walking can be influenced by factors such as conformation, fitness, and health status. This page includes a collection of peer-reviewed research studies and scholarly articles that explore the biomechanics, physiological effects, and implications of walking in equine health and performance.

Hodson E, Clayton HM, Lanovaz JL.Video (60 Hz) and force (2000 Hz) data were collected from 5 sound horses during walking. Forelimb data were analysed for 8 strides (4 left, 4 right) per horse to determine sagittal plane kinematics and ground reaction forces (GRFs). The results suggested that brachial rotation was responsible for protraction and retraction of the limb as a whole, while rotations of the scapula and antebrachium elevated the distal limb during breakover and early swing then lowered it in preparation for ground contact. The coffin joint was flexed maximally at the time of peak longitudinal braking force, which o...

Amitrano FN, Gutierrez-Nibeyro SD, Schaeffer DJ.OBJECTIVE To determine and compare the effect of hoof boots (HBs) and shoes with a toe extension on stance duration, ground reaction force, and sole length in contact with the ground in nonlame horses during walking. ANIMALS 6 nonlame Standardbreds. PROCEDURES Force plate gait analyses of the forelimbs were performed while the horses were walking barefoot before manipulation of feet (baseline), while the horses were walking fitted with HBs, while the horses were walking shod with toe-extension shoes, and while the horses were walking barefoot after shoe removal. Horses underwent radiography of...
St George LB, Pugliese BR, Hobbs SJ, Brisbois AL, Sinclair JK, Kirker-Head CA.To investigate the effects of novel legwear designed to limit metacarpophalangeal joint (MCPJ) extension and redirect loading forces from the flexor apparatus through analyses of 2-D kinematic and kinetic data. Methods: 6 adult horses without musculoskeletal disease. Methods: Horses were subjected to 4 treatments: control (no legwear), inactive legwear (unlimited legwear extension), and active legwear with mild (30°) and moderate (20°) legwear extension limitation. Two-dimensional kinematic data were collected for the right forelimb (FL) during walk and trot and from leading and trailing FLs...
Schamhardt HC, Hartman W, Lammertink JL, Badoux DM.Strain tracings obtained from the tibial cortex of walking ponies reveal peaks in the principal tension and compression strains occurring immediately before and after the support phase. Evidence is presented that the presupport peak is caused by inertial forces.
