What characterizes a double-step gait?

A double-step gait is characterized by a noticeable difference in the length or timing of alternate steps. This means that one foot may spend more time on the ground or, conversely, the steps taken by each foot may be of different lengths. This type of gait can indicate underlying issues such as balance problems, neurological deficits, or muscle control difficulties. The irregularity in the stepping pattern is pivotal to diagnosing and understanding the nature of the gait anomaly.

In contrast, the other options address different aspects of gait mechanics. Dragging feet toward crutches may indicate instability or weakness but does not necessarily create a double-step pattern. Excessive hip adduction during the swing phase suggests a different gait disturbance related to the positioning of the legs rather than the timing or length of steps. Meanwhile, the swing leg crossing behind the stance leg, known as scissor gait, is a specific gait abnormality that is not aligned with the definition or characteristics of a double-step gait. Understanding these distinctions helps professionals assess various gait issues effectively.
