Once the foot is flat on the ground, the hip gradually extends in preparation for weight acceptance as the whole-body moves forward over the stance foot. Between 30-50% of the gait cycle, the hip flexor muscles are eccentrically acting as the hip continues to extend, until reaching maximal extension at approximately 10-15 degrees past neutral. [3]
Pronation is a normal, desirable, and necessary component of the gait cycle. [4] Pronation is the first half of the stance phase, whereas supination starts the propulsive phase as the heel begins to lift off the ground.

A mature walking pattern is characterized by the gait cycle being approximately 60% stance phase, 40% swing phase. [18] Initiation of gait is a voluntary process that involves a preparatory postural adjustment where the center of mass is moved forward and laterally prior to unweighting one leg. The center of mass is only within a person's base ...
The popliteus muscle in the leg is used for unlocking the knees when walking, by laterally rotating the femur on the tibia during the closed chain portion of the gait cycle (one with the foot in contact with the ground). In open chain movements (when the involved limb is not in contact with the ground), the popliteus muscle medially rotates the ...
Cutaneous reflexes demonstrate variations in the muscles activated and the timing at which they are activated depending on which portion of the gait cycle the stimulation occurs. This variation suggests a functional role for the reflex to provide us with a smooth gait alteration when encountering or anticipating obstacles and challenging terrain.
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 ...
Dorsiflexion of the foot: The muscles involved include those of the Anterior compartment of leg, specifically tibialis anterior muscle, extensor hallucis longus muscle, extensor digitorum longus muscle, and peroneus tertius. The range of motion for dorsiflexion indicated in the literature varies from 12.2 [8] to 18 [9] degrees. [10]
Gait analysis is the systematic study of animal locomotion, more specifically the study of human motion, using the eye and the brain of observers, augmented by instrumentation for measuring body movements, body mechanics, and the activity of the muscles. [1] Gait analysis is used to assess and treat individuals with conditions affecting their ...
