Muscular Dystrophy (MD) Practice Test

Distal weakness pattern involving face, hands, and forearms is characteristic of which dystrophy?

Myotonic Dystrophy Becker Muscular Dystrophy Limb-Girdle Muscular Dystrophy Duchenne Muscular Dystrophy

Correct Answer:

Myotonic Dystrophy

Explanation:

Distal weakness with facial involvement is a hallmark of myotonic dystrophy. This condition features myotonia (delayed relaxation after contraction) and weakness that often starts in distal muscles of the hands and forearms, while also affecting facial muscles, producing ptosis and facial weakness. By contrast, Duchenne/Becker and limb-girdle muscular dystrophies mostly affect proximal muscles—the shoulder/hip girdles—early on, with less emphasis on the face and distal hand/forearm muscles. So the described pattern best fits myotonic dystrophy.
