Dr. Randall Light discusses Carpal Tunnel Syndrome.
If you have a numb painful hand that keeps you awake at night, you may have Carpal Tunnel Syndrome. Carpal Tunnel Syndrome is the most common form of nerve compression that people experience.
The diagnosis is made based on symptoms, the physical exam, and in more advanced cases, a nerve conduction test.
The nerve conduction test is done by putting some clips and electrodes on a person’s hand, making some measurements and then they feel a brief but definite shock and the response of the nerve is recorded on screen. Unlike X-rays, which look at how things are put together, a nerve conduction test looks at how things are working and it can be used to localize the abnormality of the nerve and confirm the diagnosis.
