- Quadriceps gait is a gait in which the trunk leans forward at the beginning of the stance phase to lock the knee when the quadriceps femoris muscle is weak or paralyzed1. The quadriceps muscles help to straighten the knee, absorb force when the heel hits the ground, flex the hip, maintain correct posture and balance, move and stabilize the patella, and regulate gait2. During quadriceps gait, the hip flexes to 30°, the ankle becomes dorsiflexed, and the knee flexes 60° but then extends approximately 30° due to the contraction of the sartorius muscle3. The quadriceps act concentrically to initiate knee extension4.Learn more:✕This summary was generated using AI based on multiple online sources.
