Nerve Conduction Studies
Nerve conduction studies are often done along with an
electromyogram to determine if a nerve is functioning
normally. It may be recommended if you have symptoms of
carpal tunnel syndrome or ulnar nerve entrapment. The
doctor conducting the test will tape wires (electrodes) to the
skin in various places along the nerve pathway. Then the
doctor stimulates the nerve with an electric current. As the
current travels down the nerve pathway, the electrodes placed
along the way capture the signal and measure its speed.
In healthy nerves, electrical signals can travel at speeds of up
to 120 miles per hour. If the nerve is damaged, however, the
signal will be slower and weaker. By stimulating the nerve at
various places, the doctor can determine the specific site of
the injury. Nerve conduction studies also may be used during
treatment to test the progress being made. Although you may
initially be startled by the suddenness of the stimulation, it is
not usually painful and most people are comfortable during
the testing procedure. The shock is similar to one received
when you touch a doorknob after walking across carpeting.
All Divisions of Southeastern Orthopaedic Specialists, P.A.
have Board Certified Physical Medicine and Rehabilitation
Physicians who are Interventional Specialists trained in the
administration and interpretation of these studies.
