Question

Double support, when both feet are on the ground, represents approximately what percent of the gait cycle?

20%
80%
60%
40%

Answer 1

Double support represents approximately 20% of the gait cycle, with each of the two double support phases constituting about 10% each. The correct option is 1.

Step-by-step explanation:

The question is asking about the percentage of the gait cycle that is attributed to the phase where both feet are on the ground, known as double support. During the gait cycle, an individual's walk is split into two main phases: stance and swing.

The double support phase occurs twice in each cycle: once when shifting weight from one foot to the other (initial double support) and again just before one foot leaves the ground (terminal double support).

The approximate percentage of the gait cycle occupied by double support is 20%. Specifically, each double support phase takes about 10% of the cycle, adding up to a total of 20% when combined. The correct option is 1.
