Which phase begins at 0% of the gait cycle?

Which phase begins at 0% of the gait cycle?

• A. Loading response
• B. Midstance
• C. Terminal stance
• D. Initial contact

Answer: (D)

The main idea is that the gait cycle starts at the moment the foot first contacts the ground. This instant, known as initial contact or heel strike, marks 0% of the cycle. From there, the body progresses through loading response, midstance, and terminal stance as the stance limb supports the body and prepares for push-off, before moving into swing phases. So the phase that begins the cycle at 0% is initial contact. The other phases occur after this starting point, with loading response following the initial contact and the others following in sequence.
