While assessing a child with Duchenne muscular dystrophy, which symptom is typically expected?

Duchenne muscular dystrophy (DMD) is a genetic disorder characterized by progressive muscle degeneration and weakness. One of the hallmark symptoms of DMD that is commonly observed in children is a waddling gait. This gait pattern occurs due to muscle weakness in the hips and thighs, which affects the child's ability to walk with stability and strength. The weak muscles lead to difficulties in propulsion and maintaining balance, commonly resulting in a swaying movement as the child walks, hence the term "waddling gait."

It is important to note that the other symptoms listed, such as blurred vision, drooping eyelids, and difficulty swallowing, are not typically associated with DMD. Each of those symptoms can relate to other medical conditions or muscular dystrophies, but they are not characteristic of Duchenne muscular dystrophy. This specificity aids in the identification and assessment of the disorder in clinical settings. Understanding these symptoms can enhance awareness and support for children affected by DMD and facilitate appropriate management and intervention strategies.
