There are different types of muscular dystrophy. Some types show up early, and others show up later. Your child's symptoms will depend on what type he or she has. They will also depend on how severe your child's case is and how far the disease has progressed.

For most types of muscular dystrophy, the main symptom is general weakness in the arms, legs, hips, or shoulders. Other symptoms include:

• Facial weakness.
• Trouble walking.
• Frequent tripping.
• Learning delays.
• Heart and lung problems.
