Quantitative Muscle Ultrasound – Normal values and Development of a Neuromuscular Disease Database

Overview

About this study

The purpose of this study is to

  1. To develop a database of normal values for muscle thickness and echo-intensity in American children and adults.

  2. To determine the sensitivity and specificity of muscle ultrasound in diagnosing neuromuscular disease in pediatric patients referred for EMG testing at the Mayo Clinic.
