Electrodiagnosis of lumbar radiculopathy.

The evaluation of patients with suspected lumbar radiculopathy is one of the most common reasons patients are referred for electrodiagnostic testing. The utility of this study depends on the expertise of the physician who plans, performs, and completes the study. This article reviews the strengths and weaknesses of electrodiagnosis to make this diagnosis, as well as the clinical reasoning of ap...

Electrodiagnosis in Cranial Botulism

Botulism is an acute neurologic disorder that causes potentially life-threatening neuroparalysis resulting in weakness and laccid paralysis. In addition to the autonomic nervous system, botulism may involve only the cranial nerves, thus posing special diagnostic problems. Almost all cranial nerves are not easily testable. The anatomical and physiological characteristics of the spinal accessory ...

Electrodiagnosis in neuromuscular disorders.

2. The normal sensori-motor nerve conduction with absent F-waves and tendon jerks of a moderately de-saturated semiconscious patient in the intensive care unit may be seen in: a. A classical pattern of critical illness myopathy involving both proximal and distal muscles b. Post-synaptic neuromuscular disorder c. The early stages of motor neuron disease (MND) (axonal loss) before the period of W...

Electrodiagnosis of demyelinating neuropathies.

The inflammatory demyelinating neuropathies constitute a significant proportion of the acquired polyneuropathies. Major progress in finding the causes and in the treatment of these neuropathies has been made over the last decade. Early recognition is of paramount importance, because timely and appropriate treatment can largely reduce morbidity and disability. Electrodiagnosis plays a key role i...
