Duchenne muscular dystrophy tends to start early in childhood and usually affects boys. It's caused by a gene change that usually is passed from parent to child. Risk factors include a family history of muscular dystrophy.

Symptoms of Duchenne muscular dystrophy can include frequent falls, trouble rising from a lying or seated position, trouble running and jumping, a waddling gait, walking on the toes, and muscle pain and stiffness.

Treatment for Duchenne muscular dystrophy aims to manage symptoms and slow the disease. Treatment choices include medicines, physical therapy, mobility aids, and sometimes breathing aids and surgery.
