Muscle Ultrasound examination (MUS) is a non-invasive, painless and inexpensive technique to evaluate neuromyopathies. These features are crucial in pediatric population. Muscle findings in neuromyopathies need a proper interpretation, but MUS normative data are scant in pediatric subjects. We performed a MUS study approved by our Local Ethic Committee and collected pediatric normative data in 120 healthy children (M 49-F 51; mean age 10,44 and SD 0,6 years; range 2–16). Children were of six age-related groups. We measured the thickness, the echogenicity and the macro architecture in the following muscles: Tibialis Anterior, Extensor Hallucis Longus, Vastus Intermedius, Rectus Femoris, Gastrocnemii, Soleus, Brachioradialis, Forearm-Flexors,
