Which event occurs at approximately 30% of the gait cycle?

Which event occurs at approximately 30% of the gait cycle?

• A. Next initial contact
• B. Heel rise
• C. Feet adjacent
• D. Opposite initial contact

Answer: (B)

The question tests timing of gait cycle events and when the heel lifts to begin propulsion. In walking, the cycle splits into stance and swing, with key events mapped to approximate percentages. Heel rise happens as the body is finishing stance and preparing to push off, so it begins around the 30% mark of the cycle, just before toe-off. This makes heel rise the best match for an event occurring at about 30% of the gait cycle. For context, initial contact starts the cycle at 0%, the other foot’s initial contact occurs roughly midway, and “feet adjacent” isn’t a standard gait-event landmark.
