What is the typical gait pattern observed in children with Duchenne muscular dystrophy?

The characteristic gait pattern observed in children with Duchenne muscular dystrophy is indeed a waddling gait, which arises due to weakness in the proximal muscles, particularly around the hip and trunk. This weakness affects their ability to stabilize their pelvis and maintain proper posture during walking. As a result, children compensate by adopting a wider stance and leaning their trunk to one side or the other, which creates the waddling appearance when they walk.

This gait pattern reflects the muscle degeneration and progressive nature of the condition, leading to difficulties in balance and coordination. Observing a waddling gait is also a sign that the child may be experiencing fatigue, which is common in progressive muscular dystrophies.

In contrast, other gait patterns like a stiff-legged gait or a high-stepping gait are not typical for this condition. Normal gait patterns would not be expected as the disease progresses and causes muscle weakness. Understanding the implications of the waddling gait in Duchenne muscular dystrophy helps in early identification and management of the condition.
