What is muscular dystrophy?
How is it Caused?
About 50% of all cases have this variety, it typically affects boys. Symptoms include:
- Frequently falling
- Difficulty lifting oneself
- Difficulty running and jumping
- Waddle-like walk
- Walking on toes
- Abnormally large calf muscles
- Muscle pain/ stiffness
- Learning disabilities
Similar symptoms to the Duchenne variety, generally milder with a slower progression. Symptoms typically start in the teenage years, but may not occur until adulthood.
- Corticosteroids: (ex. prednisone) Help improve the muscle's strength and fuction, as well as delay certain MD progression. Prolonged use of these may cause weight gain and weaken bones.
- Heart medications: (ACE inhibitors or beta blockers) Only used if MD affects the heart.
- Range-of-motion and stretching exercises: Keep joints as flexible as possible.
- Exercise: Low-impact aerobic exercise helps maintain strength, mobility,and general health.
- Braces: Keep muscles and tendons flexible, also slow the progression of contractures. They provide support for weakened muscles.
- Mobility aids: Canes, walkers, and wheelchairs help maintain mobility/independence.
- Breathing assistance: Machines may be used for MD caused sleep apnea, or, if needed, a ventilator to force air in and out of lungs.
Surgery can correct spinal curvature that makes breathing more difficult.
