For a four-point reciprocal gait pattern with AFOs, which muscle function is essential for reciprocal limb advancement?

• A. Ankle plantarflexors
• B. Hip extensors
• C. Knee flexors
• D. Hip flexors

Answer: (D)

Moving a leg forward in a four-point reciprocal gait with AFOs relies on pulling the thigh into swing, and that is accomplished primarily by the hip flexors. The hip flexors, especially the iliopsoas, initiate the forward swing of the leg, allowing the foot to clear the ground and progress during the step. The AFO helps keep the foot in a functional position, but it doesn’t drive the forward motion itself. Ankle plantarflexors contribute mainly to push-off during stance and aren’t the key drivers of forward limb advancement in this pattern. Knee flexors can aid in clearing the foot, but they don’t initiate the forward swing as effectively as the hip flexors. Hip extensors are more about stabilizing and controlling the trunk during stance rather than driving the swinging leg forward.
