You will not be able to drive for about 24 hours if you had sedation because you will still be drowsy..

What diseases can an EMG detect?

An EMG can be used to diagnose a wide variety of neuromuscular diseases, motor problems, nerve injuries, or degenerative conditions, such as:Amyotrophic lateral sclerosis (ALS)Carpal tunnel syndrome.Cervical spondylosis.Guillain-Barre syndrome.Lambert-Eaton syndrome.Muscular dystrophy.Myasthenia gravis.More items…

How many needles are used in an EMG test?

The skin will be cleansed with an antiseptic solution. Next, a fine, sterile needle will be inserted into the muscle. A ground electrode will be positioned under your arm or leg. Five or more needle insertions may be necessary for the test.

How painful is a EMG nerve conduction study?

Pain is the most common complication of EMG2 causing some level of discomfort in all patients either from the nerve conduction portion or the needle examination. Most surveys find pain more common in the needle portion. The study is typically well tolerated but for some patients it is nearly unbearable.

What happens if EMG is abnormal?

An abnormal EMG result means there is a problem in an area of muscle activity—turning on and off, when it is active, how much it is active, if it is more or less active, and fatigue. This can offer a clue in diagnosing various nerve and muscle conditions. Learn more in 10 Conditions Diagnosed With an EMG.

Do you get EMG results the same day?

Your doctor may review the results with you right after the procedure. However, if another healthcare provider ordered the EMG, then you may not know the results until you attend a follow-up appointment with your doctor.

What is a needle EMG?

During a needle EMG, a needle electrode inserted directly into a muscle records the electrical activity in that muscle. A nerve conduction study, another part of an EMG, uses electrode stickers applied to the skin (surface electrodes) to measure the speed and strength of signals traveling between two or more points.
