EMG/NCV

​

Electrodiagnostic studies technically consist of two separate components:  nerve conduction studies (NCS) and electromyography (EMG). These two individual portions of the test are commonly combined and collectively referred to as an "EMG". The two components of the test will measure electrical activity in your nerves and muscles and provide helpful diagnostic information.

 

​

Nerve conduction studies

​

Nerve conduction studies (NCS) are performed to help determine how well the nerve is functioning and to identify any potential areas of nerve entrapment. The procedure is performed by placing electrodes on the body. A device is then used to stimulate the nerve. The stimulation feels similar to static electricity, and you will experience a brief buzzing sensation. The electrodes transmit the data to a computer screen where a waveform is generated and provides information about how well the nerve is functioning. 

 

Electromyography

 

Electromyography (EMG) uses a small needle that is about the size of an acupuncture needle to transmit information from muscles. The transmitted data will provide several different pieces of diagnostic information, such as if there is nerve damage present or if there is a muscle problem (ie. myopathy).  An EMG can also potentially give a prognosis.

What you can expect

 

Most EMGs take approximately 30-60 minutes to complete. Dr. Curry will perform the entire test himself. He will walk you through each step of the procedure and make sure you are as comfortable as possible during the testing.
