In new gait terms, what is heel strike referred to as?

In contemporary gait terminology, "heel strike" is referred to as "initial contact." This term describes the very first point of contact between the heel and the ground during the gait cycle. Understanding this phase is crucial, as it marks the beginning of weight acceptance and initiates the subsequent phases of gait. Proper terminology helps in analyzing gait mechanics and identifying any deviations or dysfunctions that may exist.

The other terms refer to different phases within the gait cycle. "Foot flat" occurs after initial contact, when the entire foot is in contact with the ground. "Terminal stance" follows mid-stance and is characterized by the heel lifting off the ground as weight transitions onto the forefoot. "Mid stance" is the period where the body weight is directly over the supporting limb, typically occurring after initial contact and before terminal stance. Each of these phases serves a unique role in locomotion, which aids in understanding normal gait mechanics.
