Assessing The Neuromuscular Junction With Repetitive Stimulation Studies

Show Summary Details

Preview

The electrophysiologic technique of repetitive stimulation is an important component of the evaluation of patients with fatigue, weakness, ptosis, diplopia, dysphagia, or dysarthria. The technique requires a knowledge of the physiology and pathophysiology of neuromuscular transmission and the basic techniques of nerve conduction studies for proper application and interpretation. Errors in technique can produce falsely positive or negative results. The test must be individualized for each case, with the proper selection of nerve and muscle combinations, rates of stimulation, and types of exercise. The examiner must be aware of the varied abnormalities that occur with different disease entities.
