Abstract
Neuromuscular ultrasound (NMUS) is a diagnostic technique that is now commonly used
to complement electrodiagnostic studies when evaluating for suspected peripheral nerve
pathology. The use of NMUS has been described in focal mononeuropathies, polyneuropathies,
and motor neuron disease. This article provides a general overview of NMUS for the
evaluation of peripheral neuropathies based on clinical practice guidelines, primary
literature, and expert opinion. The characteristic changes detected by NMUS are described
in focal mononeuropathies (including entrapment and other causes), polyneuropathies
(including demyelinating and axonal processes), and motor neuron disease.
