Electromyography (EMG) is a diagnostic technique for evaluating and recording electrical activity in skeletal muscles. It is conducted using needles, also referred to as electrodes, that are inserted through the skin and into the muscle. Electrical activity is detected by the electrodes and displayed on an oscilloscope for medical professionals to interpret the activity. It's common for a patient to be asked to contract the muscle where the electrode was inserted. This produces waves on the oscilloscope that provides insights about the ability of the muscles response to nerve stimulation.
A related procedure may also be performed, called a nerve conduction study (NCS), in conjunction with an EMG. NCS measures the speed and amount of conduction of an electrical impulse through the nerve.
EMG is conducted on an outpatient basis at our clinic. With both EMG and NCS procedures, you will be able to return to your usual activities, unless advised otherwise. Every patient's situation is unique; though we will provide you with the right care and advisement.
A nerve conduction study (NCS) measures the speed of an electrical impulse moving through the nerve. The study can help determine any sort of nerve damage. Electrodes are attached to the skin where a nerve is to be tested. One electrode sends an electrical impulse while another records the activity.
A related procedure, called Electromyography (EMG), is often done in conjunction with a nerve conduction study. An EMG measures the electrical activity in the muscles.
The combination of NCS and EMG procedures helps determine where there is nerve disorder or muscle disorder. NCS determines problems with the nerve, while an EMG detects proper muscle function in response to stimulus performed on the nerve.
We perform NCS procedures on an outpatient basis. With both EMG and NCS procedures, you will be able to return to your activities, unless advised otherwise. Every patient's situation is unique; though we will provide you with the right care and advisement.
Botox has been increasingly used in Neurology practice. In addition to its popular use for cosmetic purpose, it has been used in multiple neurological conditions. Botox works by blocking the neurotransmitter release from nerve endings to muscle, allowing the muscle to relax. As a result, abnormal movements or muscle contractions are decreased. It can be a possible treatment for the following conditions:
Every individuals response to Botox treatments varies. However, the rate of success is high and a majority of patients who receive Botox are satisfied by the benefits. It must also be noted that it is not a cure. The effects typically last 3 months and repeated treatment is necessary.
An electrencephalogram (EEG) is a test that identifies the presence of abnormalities in brain waves, or electrical activity of the brain. Small disc-like electrodes with wires attached, are placed on the scalp. These electrodes detect electrical charges caused by activity of brain cells. The resulting charges are displayed on a monitor for a neurologist to interpret the findings.
EEG is generally considered a safe procedure. There is no physical sensation produced and no risk of electrical shock. Depending on a patient's medical condition there may be some risks; especially to those with a seizure disorder. The flashing lights or deep breathing can cause a seizure. Though this is rarely the case. If a seizure does arise it is treated immediately. It is important to discuss all medical conditions with the neurologist before conducting any procedure.
A BAER test is an acronym for Brainstem Auditory Evoked Reponse. This test detects electrical activity in the cochlea and auditory pathways in the brain in much the same way that an antenna detects radio or TV signals or an EKG detects electrical activity of the heart.
The response is collected with a speciic computer though electrodes placed on the scalp and earlobes. The stimulus click produced by the computer is directed into the ear using headphones, Each ear is tested individually, and the test usually is complete in 10 -15 minutes. A printout of the test results should show spikes in your brain activity each time you heard one of the clicking sounds or other tones.
The Visually Evoked Response (VER) or Visually Evoked Potential (VEP), measures the electrical response of the brain's primary visual cortex to a visual stimulus. To measure the electrical response, electrodes are placed on the scalp. The electrodes connect to an electrodiagnostic test system. When a visual stimulus is presented, an evoked response is created from the visual cortex. The response is detected by the electrodes and sent to a special diagnostic computer.
