Electromyography (EMG) and Nerve Conduction Studies in St. Louis
Electromyography (EMG) measures the electrical discharges made by the muscles. Nerve conduction studies, offered by Anthony Margherita, MD (measuring nerve conduction velocity) determine how well individual nerves can transmit electrical signals. Measuring the electrical activity in muscles and nerves can help detect the presence, location, and extent of diseases or conditions that can damage muscle tissue (such as muscular dystrophy) or nerves (such as carpal tunnel syndrome). In the case of nerve injury or compression, the site of nerve damage can often be localized and characterized. EMG and nerve conduction studies are often done together to provide more complete information regarding proximal or distal nerve function.
Electromyography (EMG) is done to:
- Identify the presence of peripheral or proximal nerve damage by isolating abnormalities in the distribution of a specific nerve or nerve root.
- Determine the extent and severity of such damage, thereby guiding treatment decision making.
- Assist in following the course or recovery from a nerve injury, thereby helping in the determination of prognosis and recovery.
- Differentiate muscle from nerve pathology in the circumstance of a muscle disease. Typical clinical conditions that are amenable to EMG examination include:
- Herniated disks.
- Lesions or disorders of the brachial or lumbar plexus.
- Spinal stenosis where a nerve root is considered to be producing nerve root related symptoms.
Nerve conduction studies is done to:
- Detect and evaluate damage to the peripheral nervous system from disorders such as carpal tunnel syndrome.
- Localize the source of abnormal sensations, such as numbness, tingling, or pain.
- Differentiate disorders of nerve conduction (myein) or impairment of fiber transmission (axons).
- Evaluate conditions affecting the peripheral nervous system, such as diabetic neuropathy.
