Carpal Tunnel Electrodiagnostic

There are at least two types of electrodiagnostic tests for carpal tunnel identification. These two tests are identified as "Nerve Conduction Tests" and "Electromyographies" by medical doctors and neurologists that specialize in the diagnostic procedures associated with this disorder of the wrist.

While these steps are effective in assisting a doctor in the diagnosis of carpal tunnel, they typically are not used as a first step in the diagnostic procedure. Usually, the first step is to determine the cause of the condition. The sufferer of the symptoms that are typically associated with this condition is usually evaluated to determine if there are underlying medical conditions, injuries, or if repetitive motions are experienced.

Laboratory and Imaging Tests

Once a specific cause or a theory regarding a cause has been established, the individual that is suspected of having carpal tunnel will have to go through laboratory and imaging tests. A basic first test may be an X-Ray in order to determine the physical impact that the compression occurring within the carpal tunnel canal is having on the regions around it.

There are many different imaging tests that may be able to diagnose and determine the severity of carpal tunnel in many individuals. These tests include the test called "MRI" which stands for "Magnetic Resonance Imaging" and the Ultrasound test. These tests are preferred by medical professionals as they show more details than the basic X-Ray test does.

Nerve Conduction Test

The nerve conduction test is done to mostly determine if there is actual damage to the part of the nervous system that is considered to be "Peripheral". These particular nerves come from the brain and the region of the spinal cord and then branch out throughout the body - including the wrist region.

The test works to determine the response rate of the nerves that are located in and around the carpal tunnel canal of the body. These tests are very productive in determining if an individual suffers through the symptoms that they experience due to the fact that they are experiencing carpal tunnel syndrome. Many neurologists will use this type of electrodiagnostic test in order to confirm their suspicion of the syndrome.

Electromyographies

Electromyographies are electrodiagnostic tests that work to determine the overall health associated with the muscles. It also works to determine how well the motor function nerves, such as the median nerve, are controlling the muscles. The neurologist that performs this particular electrodiagnostic test will place a relatively thin needle that is referred to as an "electrode" into the skin and right into the muscle.

The needle evaluates the electrical based activity that is produced by the muscles. While this is being performed, the neurologist will evaluate a special monitor that is referred to as an "Oscilloscope". Additionally, they will listen to the sounds being emitted from the machine. This test is beneficial in determining if carpal tunnel complications are present, and to what degree. If you feel as if you are having an issue with carpal tunnel, it is best to make an appointment with your doctor for diagnostic tests.
