Which body parts are weakened first in facioscapulohumeral muscular dystrophy?

In facioscapulohumeral muscular dystrophy, the condition typically manifests with weakness and wasting in the muscles of the face, the area around the shoulder blades, and the upper arms.12

This form of muscular dystrophy generally begins in these specific regions during the teenage years. Unlike some other forms of the disease, it typically progresses more slowly, and most affected individuals have a normal life span. Over time, the condition may also lead to leg weakness, which can result in a waddling gait and a condition known as "foot drop".12
