Becker Muscular Dystrophy



Becker muscular dystrophy is an inherited disorder that involves slowly worsening muscle weakness of the legs and pelvis.

Causes of Becker Muscular Dystrophy

Becker muscular dystrophy is very similar to Duchenne muscular dystrophy, except that it gets worse at a much slower rate.

The disorder is passed down through families (inherited). Having a family history of the condition raises your risk.

Becker muscular dystrophy occurs in approximately 3 - 6 out of every 100,000 males. It is less common than Duchenne muscular dystrophy.

Symptoms of Becker Muscular Dystrophy

Females rarely develop symptoms. Males will develop symptoms if they inherit the defective gene. Symptoms usually appear in boys at about age 12, but may begin later.

Muscle weakness of the lower body, including the legs and pelvis area, slowly gets worse, causing:

Muscle weakness in the arms, neck, and other areas is not as severe as in the lower body.

Other symptoms may include:

Exams and Tests for Becker Muscular Dystrophy

The health care provider will do a nervous system (neurological) and muscle examination. A careful medical history is also important, because the pattern of symptom development resembles that of Duchenne's muscular dystrophy. However, Becker muscular dystrophy gets worse much more slowly.

An exam may find:

Muscle deformities, including:

Tests that may be done include:

Treatment for Becker Muscular Dystrophy

There is no known cure for Becker muscular dystrophy. The goal of treatment is to control symptoms to maximize the person's quality of life. Some doctors prescribe steroids to help keep a patient walking for as long as possible.

Activity is encouraged. Inactivity (such as bed rest) can make the muscle disease worse. Physical therapy may be helpful to maintain muscle strength. Orthopedic appliances such as braces and wheelchairs may improve mobility and self-care.

Genetic counseling may be recommended. Daughters of a man with Becker muscular dystrophy may carry the defective gene and could pass it onto their sons.

Support Groups for Becker Muscular Dystrophy

You can ease the stress of illness by joining a support group where members share common experiences and problems.

Outlook / Prognosis for Becker Muscular Dystrophy

Becker muscular dystrophy leads to slowly worsening disability, although the degree of disability varies. Some men may need a wheelchair, while others may only need to use walking aids such as canes or braces.

Possible Complications of Becker Muscular Dystrophy

Increasing and permanent disability leading to:

When to Contact a Medical Professional

Call your health care provider if:

Prevention of Becker Muscular Dystrophy

Genetic counseling is a good idea if there's family history of Becker Muscular Dystrophy in your family.
