Which statement best describes the order of muscle involvement in DMD?

Explanation:
In Duchenne muscular dystrophy, weakness starts in the proximal muscles—those around the hips and thighs. This leads to a characteristic waddling gait and the need to use Gowers' maneuver to get up from the floor. As the disease progresses, the weakness spreads to proximal muscles of the shoulders and upper arms. Distal muscles, like those in the hands and feet, are relatively preserved early and become involved later. Facial muscles are not the first to be affected and are typically spared early stages. So the typical pattern is proximal before distal, not distal before proximal, not only facial muscles, and not random.
