Muscle disorder

Definition

A muscle disorder includes patterns of weakness, electromyogram (EMG) findings, or biopsy results that suggest a muscle problem. The muscle disorder can be inherited, such as muscular dystrophy, or acquired, such as alcoholic myopathy.

The medical name for muscle disorder is myopathy.

Alternative Names

Myopathic changes; Myopathy; Muscle problem

Symptoms

The main symptom is weakness.

Other symptoms include cramps and stiffness.

Exams and Tests

Blood tests sometimes show abnormally high muscle enzymes. If a muscle disorder might also affect other family members, genetic testing may be done.

When someone has symptoms and signs of a muscle disorder, tests such as an electromyogram, muscle biopsy, or both can confirm whether it is a myopathy. A muscle biopsy examines a tissue sample under a microscope to confirm disease. Sometimes, a blood test to check for a genetic disorder is all that is needed based on someone’s symptoms and family history.

Treatment

Treatment depends on the cause. It usually includes:

  • Bracing
  • Medication
  • Physical therapy
  • Preventing the condition from getting worse by treating the underlying condition causing the muscle weakness
  • Surgery (sometimes)

Your health care provider can tell you more about your condition and treatment options.
