Feedback:
Symptoms of Duchenne muscular dystrophy begin to appear around the age of 3 years. Before this, the child may have noticeable developmental delays. The child's gait appears as a waddle and a positive Gower's sign occurs. A positive Gower's sign is exhibited when the child needs to use the upper extremity muscles to compensate for weak hip muscles. The child also may walk on the toes, fall frequently, and have difficulty hopping or running, but these are not the Gower's sign. With cerebral palsy, the child has a scissor-like gait.
