Myopathic changes

Definition

Myopathic changes are weakness or biopsy results that suggest a muscle disorder, such as muscular dystrophy.

Symptoms

The main symptom is weakness.

Signs and tests

An electromyogram can confirm the presence of a myopathy.

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