The results of a study utilizing computerized real-time sonography (CRS) to image muscles in patients with neuromuscular disease are presented for 67 patients, 37 with neuromuscular disease and 4 with upper motor neuron disease, and 26 age-matched healthy controls between the ages of 2 days and 59 years. CRS is a safe, noninvasive, atraumatic method for evaluating a broad range of neuromuscular diseases. It is capable of differentiating myopathies or dystrophies from neurogenic atrophies and floppy infants with "central" hypotonia from those with neuromuscular diseases.
