Which phase of gait is characterized by both feet being on the ground?

The phase of gait characterized by both feet being on the ground is known as the double support phase. This phase occurs when one foot is in contact with the ground while the other foot is also in contact, typically during the transition between the swing phase of one leg and the landing of the other leg.

Double support is particularly vital for maintaining stability and balance while walking, especially at slower speeds. It is important to note that this phase occurs in the stance phase of gait, which encompasses all the phases when the foot is in contact with the ground. However, the term "double support" specifically highlights the moment when both feet are on the ground, making it the most accurate description for the question posed.

In contrast, the single support phase occurs when only one foot is on the ground, which happens after the double support phase during the gait cycle. The stance phase includes both single and double support phases, but it does not specifically refer to the moment when both feet are grounded. The lift-off phase describes the action of one foot leaving the ground, and thus is not characterized by both feet being in contact with the ground.
