Living with Brody myopathy

A muscle condition with cramping and stiffening after exercise, especially in the cold.

Understanding Brody myopathy

Brody myopathy is a condition of the skeletal muscles (muscles used for movement) with cramping and stiffening after exercise.

Symptoms typically begin in childhood. They are usually painless, though sometimes mildly uncomfortable, and muscles relax after a few minutes of rest. Arms, legs, and face muscles, especially the eyelids, are most often affected, and cold temperatures can make symptoms worse. In some people, exercise leads to muscle breakdown (rhabdomyolysis), which can turn urine red or brown.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Muscle cramps after exercise
  • Muscle stiffness after exercise
  • Delayed motor development
  • Difficulty running
  • Muscle breakdown with red or brown urine (rare)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists and genetic specialists.

  3. Consider genetic testing

    Changes in ATP2A1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Muscular Dystrophy Association may keep lists of experts for this condition.
