Gait analysis is the systematic study of animal locomotion, more specifically the study of human motion, using the eye and the brain of observers, ...
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.
Gait analysis is the study of gait in humans and other animals. This may involve videoing subjects with markers on particular anatomical landmarks and measuring the forces of their footfall using floor transducers (strain gauges). Skin electrodes may also be used to measure muscle activity.
Gait in humans is difficult to study due to ethical concerns. Therefore, the majority of what is known about gait regulation in humans is ascertained from studies involving other animals or is demonstrated in humans using functional magnetic resonance imaging during the mental imagery of gait. [13]
Gait abnormality is a deviation from normal walking ().Watching a patient walk is an important part of the neurological examination. Normal gait requires that many systems, including strength, sensation and coordination, function in an integrated fashion.
Gait deviations are nominally referred to as any variation of standard human gait, typically manifesting as a coping mechanism in response to an anatomical impairment. Lower-limb amputees are unable to maintain the characteristic walking patterns of an able-bodied individual due to the removal of some portion of the impaired leg.
The Gait Kinetic Index (GKI) is the systematic study of the human motion, based on the Gait analysis, which allows to measure extensively the gait pathology taking into consideration kinetic aspects of gait pattern.
Video motion analysis is a technique used to get information about moving objects from video. Examples of this include gait analysis , [ 1 ] sport replays , speed and acceleration calculations and, in the case of team or individual sports, task performance analysis.
