Myoanatomic Atlas for Clinical EMG

For a patient with weakness due to neuromuscular disease, the EMG and nerve conduction studies are probably reasonably diagnostic in about 75% of cases.

Role of EMG evaluation in muscle hyperactivity syndromes.  This article reviews the electromyographic features and pathophysiology of fasciculations, high frequency discharges, myokymia, and neuromyotonia.

Electrodiagnostic criteria for the diagnosis of acute and chronic inflammatory demyelinating polyneuropathies.


The H-reflex is not purely a monosynaptic reflex, although is is commonly regarded as so in clinical practice.
