Symptoms

The main symptom is weakness.

Other symptoms include cramps and stiffness.

Signs and tests

Sometimes, a muscle biopsy is done. This allows a tissue sample to be examined under a microscope and may confirm a specific disease.

Treatment

Treatment depends on the cause. It usually includes:

  • Bracing
  • Medication
  • Physical therapy
  • Preventing the condition from getting worse
  • Surgery (sometimes)
