EMG (Electromyography) is a test to diagnose if there is a pinched nerve in the spine or extremities. It also diagnosis nerve diseases like peripheral neuropathy or muscle diseases like myopathy.
EMG answer questions like:
Where is my pain coming from?
Why are my feet burning?
Why is my hand going numb?
Why am I losing strength in my hands or feet?
Do I have a pinched nerve in my neck or low back?
Our diagnostic team will endeavor to answer these questions so that you can have the correct diagnosis.
Nerve Conduction Studies (NCS) are the first part of the test. Small sticky sensors are applied to the skin over the area to be tested. I small directed shock by a probe applied to the skin will activates the nerve so the sensors can measure how the nerve is working. In older EMG tests a needle was inserted down by the nerve and the needle was shocked. We do not shock the needle. That is the old timey way, although there are still some practitioners in town that still do it that way and it is much more painful.
Electromyography (EMG) is the second part of the test. A small 29 gauge pin is inserted into the muscle. The pin acts as microphone. No shock is given. The muscle is contracted by the patient and we can see if the muscle is losing its nerve signal. A minimum of 5 muscles are tested per extremity.
Interpreting the data from the NCS and EMG tells us right where the nerve is having problems and the severity. And we will give you your results right after the test is over.
How do I prepare for my EMG test?
Do not wear lotion the day of the test.
Go ahead and take your regular medications.
