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.
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.
Upstroke duration: time elapsed between the onset of an upstroke and the onset of a downstroke. Downstroke duration: time elapsed between the onset of a downstroke and the onset of an upstroke. Phase: if an organism has both front and hind wings, the lag of a wing pair relative to the other (reference) wing pair.
The gait analysis is modulated or modified by many factors, and changes in the normal gait pattern can be transient or permanent. The factors can be of various types: Extrinsic: such as terrain, footwear, clothing, cargo; Intrinsic: sex, weight, height, age, etc. Physical: such as weight, height, physique; Psychological: personality type, emotions
The complexity of gait arises from the need to adapt to expected and unexpected changes in the environment (e.g., changes in walking surface or obstacles). Visual , vestibular , proprioceptive , and tactile sensory information provides important feedback related to gait and permits the adjustment of a person's posture or foot placement ...
A (bipedal) gait cycle is the time period or sequence of events or movements during locomotion in which one foot contacts the ground to when that same foot again contacts the ground, and involves propulsion of the centre of gravity in the direction of motion. A gait cycle usually involves co-operative movements of both the left and right legs ...

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.
