What describes the gait pattern used to propel the body forward?

• A. Constant foot drop
• B. Unison movement of limbs
• C. Alternating arm swing only
• D. Reciprocal pattern of lower extremity movement to propel body forward

Answer: (D)

Gait propulsion relies on a reciprocal pattern of leg movement, where one leg advances while the other bears weight and then alternates with the opposite leg. This alternating lower-extremity movement, often with the arms moving opposite to the legs, propels the body forward smoothly and efficiently while helping maintain balance. The other descriptions don’t fit gait propulsion: constant foot drop describes a motor deficit rather than a coordinated pattern; unison limb movement would have both sides moving together rather than alternating, hindering forward progression; and relying on arm swing alone ignores the essential role of coordinated leg movement in propelling the body forward.
