- Blood tests. A blood test can check the levels of creatine kinase (CK), an enzyme that leaks out of the muscle fibers when the fibers are being damaged.
- Tiny needles are inserted into the muscles to test their electrical activity
- Magnetic resonance imaging (MRI), an imaging study.
- Muscle biopsy.A small piece of muscle is removed for examination
