ELECTRODIAGNOSTIC TECHNIQUES

Electrodiagnostic studies.

This article overviews electrodiagnostic tests that provide evidence-based data in the treatment and management of abnormalities in nerves and muscles. There is a focused review on cardiac tests, nerve-conduction tests, low-back pain tests, seizure and epilepsy tests, and obstructive sleep apnea electrodiagnostic tests. Case reports demonstrate how these electrophysiologic tests can provide spe...

Tabes dorsalis: electrodiagnostic features.

Electrodiagnostic data have not been previously reported in tabes dorsalis. A patient with tabes dorsalis is described whose nerve conduction studies and median nerve somatosensory evoked responses (SEPs) were normal. H-reflexes were absent. SEPs of the tibial nerve suggested posterior column dysfunction. These electrodiagnostic findings correlate precisely with the known pathology of tabes dor...

Risks in Electrodiagnostic Medicine

There is a need for practitioners to be knowledgeable about potential complications from nerve conduction studies and needle electromyography as well as to know how to reduce the risk of such complications. Since a summary of risks inherent to electrodiagnostic (EDX) medicine was first published over one decade ago, publication of additional literature and technological advances warrant reasses...

Electrodiagnostic evaluation of myopathies.

Electrodiagnostic studies play an important role in the evaluation of patients suspected of having a myopathic disorder. They are used to exclude alternative diagnoses, confirm the presence of muscle disease, narrow down the differential, and identify an appropriate biopsy site. The most informative part of the electrodiagnostic study is needle electromyography. This allows for the analysis of ...
