What is indicated by the term "stride" in reference to gait analysis?

The term "stride" in gait analysis refers to a full gait cycle, which encompasses the complete sequence of movements from the point of initial contact of one foot with the ground until the next time that same foot strikes the ground again. This includes both the stance phase, where the foot is in contact with the ground, and the swing phase, where the foot is moving forward in preparation for the next step. Understanding this concept is crucial for evaluating and assessing walking patterns, as it provides insight into both the mechanical efficiency and the rhythm of locomotion.

The other concepts, while related to gait, describe different aspects. The time from heel strike to heel strike of opposite limbs pertains specifically to a specific timing aspect of the gait cycle. The distance covered in a single step is more about the step length rather than the complete stride. The repetition of walking events highlights the alternation of limbs but does not encapsulate the entire cycle attributed to a single leg's movement. Recognizing the full cycle of motion that a stride entails is essential for effectively analyzing walking patterns in clinical settings.
