This is used to diagnose symptoms of numbness, tingling, pain weakness related nerve and muscle disorders.

There are two parts to this procedure. The first part is the NCS which helps to assess the function of your nerves. Several nerves in each limb may be tested using small electric shocks at different sites along the course of the nerves.  The doctor studies the nature of the responses and the speed with which the conduction is taking place.  The second part of the test is the EMG (electromyogram) used to study the muscles. A small sterile needle electrode is inserted into selected muscles. Both components of the test will take about 45 to 60 minutes to complete. The EMG/NCS test will help to determine whether you suffer a neuromuscular condition such as a pinched nerve, neuropathy, carpal tunnel syndrome or a muscular disease.  The test causes some discomfort and pain. It can be tolerated since the impulses used are not very strong and the needle is small. Potential side effects can include, pain, mild bleeding and rarely infections.
