Tests & Diagnosis

How is Becker muscular dystrophy diagnosed?

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.[1]

Exams in a person with BMD may reveal:[1]

  • 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:[1]
