Which symptom is commonly associated with Duchenne Muscular Dystrophy?

Duchenne Muscular Dystrophy (DMD) is a genetic disorder characterized primarily by progressive muscle degeneration and weakness. One of the hallmark symptoms associated with DMD is difficulty negotiating stairs. This symptom arises because children with DMD typically experience weakness in the proximal muscles, particularly in the legs. As these muscles become weaker over time, tasks that require significant muscular strength and coordination—such as climbing stairs—become challenging.

Children with DMD often struggle with other activities that involve raising their bodies against gravity, as the advancing muscle weakness significantly impacts their mobility and overall physical capabilities. Difficulty with stairs is often one of the first noticeable signs of the condition, making it easy for parents and pediatricians to identify a potential issue early in the child's development.

The other options provided do not align with the typical presentation of Duchenne Muscular Dystrophy. While quick recovery from physical activity, increased muscle tone, and visual impairments can appear in various other conditions, they are not common symptoms associated with DMD. Thus, the correct answer reflects a key symptom that is specific and commonly seen in individuals with Duchenne Muscular Dystrophy.
