Mid-swing requires which critical event?

Mid-swing requires which critical event?

• A. Heel rise
• B. Passive knee flexion to 40°
• C. Controlled knee flexion
• D. Hip flexion to 25° and ankle dorsiflexion to 0°

Answer: (D)

Mid-swing is all about getting the leg forward while the foot clears the ground. The key actions that make this possible are lifting the thigh and positioning the foot so it doesn’t drag. Hip flexion around 25 degrees drives the limb forward, while the ankle being near neutral (dorsiflexion to about 0 degrees) keeps the forefoot off the floor and ready for landing. This combination ensures smooth progression and toe clearance as the leg swings through. Heel rise happens later, during push-off in the stance phase, not mid-swing. Knee behavior during mid-swing is part of the whole forward sweep, but the essential features that define mid-swing are hip flexion for advancement and neutral-to-dorsiflexed foot position for clearance.
