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 ...
The normal biomechanics of the foot absorb and direct the occurring throughout the gait whereas the foot is flexible (pronation) and rigid (supination) during different phases of the gait cycle. As the foot is loaded, eversion of the subtalar joint, dorsiflexion of the ankle, and abduction of the forefoot occur.
When a foot is lifted off the ground, that limb is in the "swing phase" of gait. When a foot is in contact with the ground, that limb is in the "stance phase" of gait. A mature walking pattern is characterized by the gait cycle being approximately 60% stance phase, 40% swing phase. [18]
A gait cycle is defined as the progression of movements that occurs before one leg can return to a certain position during walking, or ambulation. [2] One example of a full gait cycle is the period it takes for a foot to leave the ground until the same leaves the ground again.
The key variables for gait are the duty factor and the forelimb-hindlimb phase relationship. Duty factor is simply the percent of the total cycle which a given foot is on the ground. This value will usually be the same for forelimbs and hindlimbs unless the animal is moving with a specially trained gait or is accelerating or decelerating. Duty ...
"Wearing appropriate, supportive shoes can indirectly help prevent pain by maintaining a normal gait cycle," says Dr. Austin A. Hall, a board-certified foot and ankle surgeon.
Drop Foot is the inability to dorsiflex, evert, or invert the foot. So when looking at the Gait cycle, the part of the gait cycle that involves most dorsiflexion action would be Heel Contact of the foot at 10% of Gait Cycle, and the entire swing phase, or 60-100% of the Gait Cycle. This is also known as Gait Abnormalities. [citation needed]
Pronation of the foot refers to how the body distributes weight as it cycles through the gait. During the gait cycle the foot can pronate in many different ways based on rearfoot and forefoot function. Types of pronation include neutral pronation, underpronation (supination), and overpronation.
