What is an EMG/Nerve Conduction Study

The EMG/Nerve Conduction Study is a test performed in the office to determine if there is nerve damage somewhere in the body. By using a special nerve machine, we can detect how the nerves are functioning based off their conduction velocity- the speed at which signals are sent from the nerve root to the hands and/or feet. 
The test involves using small electrical signal to the nerves which then is then relayed to a machine which determines the speed at which the signal travels through the nerve.  We can then analyze the data detect abnormality if there is a faster or slower conduction of the signal and thus determine nerve damage

How long does it last and does it hurt?

A typical nerve conduction exam lasts between 20 to 45 minutes, depending on the extent of testing required. Most people experience minor discomfort during the procedure as the electrical impulse used in detecting nerve activity can mimic a small shock. 

What conditions can the EMG/Nerve Conduction Detect

An EMG/Nerve conduction test helps identify (detect) the following conditions:
Carpal Tunnel Syndrome
Tarsal Tunnel Syndrome
Diabetic Neuropathy
Charcot Marie Tooth
Radial Nerve Palsy
Cubital Tunnel Syndrome
Foot Drop/
