• Wear comfortable clothing that doesn’t obstruct the area that your doctor will be evaluating.

Do medications affect EMG?

Are taking any drugs. Certain drugs that act on the nervous system (such as muscle relaxants) can interfere with electromyography results. You may need to stop taking these three to six days before the test. Have had bleeding problems or are taking blood thinning drugs, such as warfarin (Coumadin®) or heparin.

What should you not do before a nerve conduction study?

Do not eat or drink foods that contain caffeine (such as coffee, tea, cola, and chocolate) for 2 to 3 hours before the test. Wear loose-fitting clothing so your muscles and nerves can be tested. You may be given a hospital gown to wear. Take a shower or bath before your exam to remove oils from your skin.

Not only friends and relatives who have had a previous EMG experience, but also physicians can sometimes discourage patients from undergoing EMG, believing that the test is very painful and of little benefit (1).

How long does a EMG take?

An EMG may take 30 to 60 minutes. Nerve conduction tests may take from 15 minutes to 1 hour or more.

Will an EMG show a pinched nerve?

EMG and NCS are tests that measure the electrical activity of the muscles and nerves of the body, usually to an arm or a leg. The tests can help identify nerve injury or muscle disease such as carpal tunnel syndrome, a pinched spinal nerve, peripheral neuropathy, myositis, or ALS.

What does an abnormal 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’.

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.

Why would someone 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.

How do you know if your EMG is abnormal?

Abnormal EMG results can show up in two ways. First, the muscle may show electrical activity at rest. On the other hand, the muscle may show abnormal electrical activity during contraction. This shows up as an abnormal action potential pattern with changes in the size or shape of the wave.

Does ALS always show up on EMG?

Patients with ALS tend to show abnormal EMG results, especially if there are significant signs of lower motor neuron (LMN, in the spinal cord) involvement. The test can identify the onset of LMN involvement before symptoms are obvious.

What does early ALS feel like?

Early stage ALS Early symptoms of ALS are usually characterized by muscle weakness, tightness (spasticity), cramping, or twitching (fasciculations). This stage is also associated with muscle loss or atrophy.
