Muscular dystrophy Episode 045

Episode summary introduction:

There are several types of Muscular Dystrophy. With that being said today will cover the two most diagnosed; Duchenne and Becker, as they are studied and researched together. Muscular dystrophy is a group of diseases causing progressive weakness and loss of muscle mass. Abnormal genes mutations interfere with the production of proteins needed to form healthy muscle.

Topic 1:

Types of MD:

Duchenner/Becker: Both can have the same symptoms as they are caused by the same gene mutation. Duchenner: Onset is in early childhood, usually between ages 2 and 3. Primarily affects boys, but in rare cases it can affect girls. Becker: has less severe symptoms starting later in life.

Topic 2:


Begins as early as age 2 or 3, first affecting the proximal muscles

Upper legs and upper arms are parts of the body that show weakness first.

Other symptoms include enlargement of the calves, a waddling gait, and lumbar lordosis (an inward curve of the spine).


Similar to those of Duchenne muscular dystrophy, but tend to be milder and progress more slowly. Symptoms generally begin in the teens but might not occur until the mid-20s or later.

Symptoms can affect the heart, lungs, throat, stomach, intestines, and spine are other parts of the body that can be affected

Progressive weakness and scoliosis result in impaired pulmonary function, which can eventually cause acute respiratory failure.

Topic 3:

Diagnosis, Treatment, and therapies are discussed.


Nursing Considerations:

  1. Preventing respiratory infections

  2. Vaccinated for pneumonia

  3. Influenza shots

  4. Try to avoid contact with children or adults who have an obvious infection.

  5. ROM

  6. Breathing treatments

  7. Pap devices while sleeping
