Electromyography (EMG)
What is Electromyography (EMG)?
Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them.
How is EMG performed ?
- EMG is done using fine Disposable Electrodes, which are thin solid pins
- The Needle is inserted just into the muscle for few seconds
- The patient is asked to contract the muscle and the activity is picked up by the electrode and displayed on the monitor and over a loud speaker.
- The number of muscles examined depends upon the working diagnosis.
Which diseases or conditions that are diagnosed by EMG ?
- Muscle disorders, such as muscular dystrophy, inflammatory myopathies
- Myotonia
- Radiculopathies
- Peripheral nerve disorders that affect the nerves outside the spinal cord, such as carpal tunnel syndrome
- Motor Neuron disease / amyotrophic lateral sclerosis (ALS)
How to prepare for an EMG ?
- Bath or shower on the day of the test; wash arms and legs well to remove body oils
- Don’t use lotion, bath oils or creams
- Wear comfortable, loose-fitting clothes
- Eat your normal meals (but you may wish to avoid tobacco or caffeine for a few hours prior to your test)
- Bring a list of medications you are taking, especially any blood thinners
-
Tell the health care provider if you :
- Bruise easily
- Have hemophilia
- Have a skin infection
Facilities
Electroencephalography (EEG) is electrophysiological monitoring method to record electrical activity of the brain. EEG refers to the recording of the brain's spontaneous electrical activity over a period of time, as recorded from multiple electrodes placed on the scalp.
A video EEG (electroencephalograph) records what you are doing or experiencing on video tape while an EEG test records your brainwaves.
A Nerve conduction study is an electrical test that is used to determine the adequacy of the conduction of the nerve impulse as it courses down a nerve. This test is used to detect signs of nerve injury.
Electromyography (EMG) measures muscle response or electrical activity in response to a nerve’s stimulation of the muscle. The test is used to help detect neuromuscular abnormalities.
RNS is an electrodiagnostic test which is used to assess the neuromuscular junction (NMJ).
A visual evoked potential is an evoked potential caused by a visual stimulus, such as an alternating checkerboard pattern on a computer screen. Responses are recorded from electrodes that are placed on the back of your head and are observed as a reading on an electroencephalogram (EEG).
A brainstem auditory evoked response (BAER) test measures how your brain processes the sounds you hear. The BAER test records your brainwaves in response to clicks or other audio tones that are played for you. The test is also called a brainstem auditory evoked potentials (BAEP) or auditory brainstem response (ABR) test.
Botulinum toxin injection therapy (BOTOX therapy) is used to treat dystonia - neuromuscular disorder that produces involuntary muscle contractions, or spasm - that affects muscles that control movement in the eyes, neck, face, limbs, voice box, or the smooth muscle in the bladder. The goal of the therapy is to reduce muscle spasm and pain.
