Can an EMG detect MS?

The test can also measure the ability of peripheral nerves to conduct impulses. EMG results are usually normal in multiple sclerosis (MS) patients, as MS doesn’t affect the peripheral nervous system.

Does nerve damage show up on MRI?

MRI is sensitive to changes in cartilage and bone structure resulting from injury, disease, or aging. It can detect herniated discs, pinched nerves, spinal tumors, spinal cord compression, and fractures.

How does a neurologist check for nerve damage?

By measuring the electrical activity they are able to determine if there is nerve damage, the extent of the damage and potentially the cause of the damage. Frequently the neurologist will recommend common, noninvasive neurological evaluations such as electromyography (EMG) and nerve conduction velocity (NCV) testing.

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.

How accurate are EMG tests?

Surface EMG has been examined in patients with myofascial pain compared to normal control subjects, and a new technique showed accuracy to differentiate 60-85% of patients with myofascial pain from control subjects, suggesting there is inherent physiologic change to muscle in a state of pain.

What does a normal EMG sound like?

The sound of positive sharp waves have been described as, like ‘claps of distant thunder’, and fibrillation potentials a higher pitched and shorter duration sound, like ‘rain on a tin roof’.

Why would a person need an EMG?

EMG results are often necessary to help diagnose or rule out a number of conditions such as: Muscle disorders, such as muscular dystrophy or polymyositis. Diseases affecting the connection between the nerve and the muscle, such as myasthenia gravis.
