Nerves Conduction In Myasthenia Gravis

Electromyogram (EMG) and nerve conduction studies Normal: The EMG recording shows no electrical activity when the muscle is at rest. There is a smooth, wavy line on the recording with each muscle contraction. The nerve conduction studies show that the nerves send electrical impulses to the muscles or along the sensory nerves at normal speeds, or conduction velocities. Sensory nerves allow the  brain  to feel pain, touch, temperature, and vibration. Not all nerves have the same normal conduction velocities. They generally get slower as a person gets older. Abnormal: Electrical activity in a muscle at rest shows that there may be a problem with the nerves used by the muscle. Abnormal wave lines when a muscle contracts may mean there is a muscle or nerve problem. Examples include a  herniated disc ,  amyotrophic lateral sclerosis  (ALS), and  inflammation . In nerve conduction studies, the speed of nerve impulses is slower than normal for that ...

Result Of EMG

An electromyogram (EMG) measures the electrical activity of muscles when they're at rest and when they're being used. Nerve conduction studies measure how well and how fast the nerves can send electrical signals. Your doctor may be able to tell you some of the results of your nerve studies right after the tests. A full report may take 2 to 3 days. The results from EMG and nerve conduction studies are looked at along with other things. These include your medical history, symptoms, physical and neurological exams, and the results of other tests. All of these things may help your doctor find the problem or see how a disease is changing.

Risk Of EMG

An EMG is very safe. You may get some small  bruises  or swelling at some of the needle sites. The needles are sterile, though. There is very little chance of getting an infection. There is no chance of problems with nerve conduction studies. Nothing is put into your skin, so there is no chance of infection. The voltage of electrical pulses is too low to cause an injury.
