Which symptom may be observed in Duchenne muscular dystrophy due to pseudohypertrophy of muscles?

Pseudohypertrophy in Duchenne muscular dystrophy happens when muscle fibers are gradually lost and replaced by fat and connective tissue. This makes the muscles look larger or bulkier, especially in the calves, even though the actual muscle strength is declining. So seeing enlarged muscles is a direct manifestation of this process. Tremors or hyperactivity aren’t characteristic features of DMD related to pseudohypertrophy, and a normal gait would be unlikely because proximal leg weakness typically leads to a progressive, abnormal gait pattern rather than a normal one.
