- Becker's muscular dystrophy
- Muscular dystrophy, Becker type
- Muscular dystrophy pseudohypertrophic progressive, Becker type
- Becker dystrophinopathy
Tests & Diagnosis
Becker muscular dystrophy (BMD) may first be suspected in a person with signs or symptoms of BMD. Healthcare providers will often conduct neurological and muscle exams, as well as order specific laboratory tests. A careful medical history is also important to differentiate between BMD and Duchenne muscular dystrophy.
Exams in a person with BMD may reveal:
- Abnormally developed bones, leading to deformities of the chest and back (scoliosis)
- Abnormality of heart muscle function (cardiomyopathy)
- Congestive heart failure or irregular heartbeat (arrhythmias)
- Muscle deformities
- Contractures of heels and legs
- Fat and connective tissue (pseudohypertrophy) in calf muscles
- Muscle wasting that begins in the legs and pelvis, then progresses to the muscles of the shoulders, neck, arms, and respiratory system
Laboratory tests that help confirm the diagnosis include:
