An electromyogram is a procedure that allows a doctor to analyze the effectiveness of a nerve. This is done through measuring the electrical stimulation sent to the muscle through the nerve. There are many reasons why a nerve may not be sending an effective electrical signal. This can be due to physical blockage, nerve damage, injury, or illness. Regardless of the reason for Limited nerve signal reception, an electromyogram will allow a doctor to objectively see how their patient is doing.
What is Electromyography?
Electromyography, as mentioned above, is a diagnostic test to determine how well both nerve and muscle systems are working. The way this is measured is through electrical signal. When the brain sends a signal to the body in order to act, it does so by stimulating neurotransmitters to release electrical signals. These electrical signals travel down the nervous system towards the muscle. When properly received through the nervous tissue, these signals are then transmitted two muscles. These muscles interpret the signal and use the electrical stimulation to activate movement. However, when there is clearly a lack of movement or weakness, an electromyogram can be done to determine the source. Alternatively, an electromyogram may be used to determine problems associated with sensory nerves. With sensory nerves, things are a little bit different. In this case, the electrical simulation is based on neurotransmitters provided from the sensory organs. This electricity then travels back up through the spinal cord toward the brain in order to relay important information. When this information isn’t received properly, an electromyogram may be recommended. Additionally, if sensations of numbness or tingling are reported, I may be able to determine the source of the problem.
How is Electromyography Used?
In order for electromyography to be used, the above criteria must be met. When one of these problems is being investigated, eye doctor will make use of electromyography. To do so, I need a needle electrode may be placed into a muscle so as to effectively read the electrical signal that is received by the muscle. Alternatively, electrode stickers can be placed across the skin to measure the speed and strength of electrical signals sent. This will allow doctors to get a glimpse of the nervous system and the ability to transmit the necessary electrical signal. Once these readings have been taken, a doctor can make a decision regarding treatment interventions required.
When Should Electromyography be Used?
There are certain conditions that may dictate the need for electromyography. This includes numbness, tingling, muscle weakness, or cramping. In addition, an electromyogram may be used to diagnose conditions such as carpal tunnel. Amyotrophic lateral sclerosis and polio can also be diagnosed with the help of an electromyography. Muscular dystrophy, myasthenia gravis, and even herniated discs can all be diagnosed with the help of an electromyogram. If you have a family history of any of the above-mentioned diseases, or feel you may have these conditions, an electromyogram can help get a definite answer.
