Which dystrophy is associated with distal weakness including the face and forearms?

Explanation:
Distal weakness that includes the face points to myotonic dystrophy. This condition commonly shows weakness of distal muscles, including those of the forearms, along with facial weakness, and is often accompanied by myotonia—slowed relaxation after contraction. In contrast, Duchenne and Becker muscular dystrophy and limb-girdle muscular dystrophy primarily affect proximal muscles around the hips and shoulders early on, with facial involvement not as prominent initially. So the pattern of distal limb weakness plus facial involvement is most characteristic of myotonic dystrophy.
