EMG
Electromyography (EMG) is a method for testing the electrical activity of the muscles. This technique is performed using a procedure called electromyography. EMG may help with the diagnosis of nerve root injury or nerve compression injury.
73 Questions
Clinical correlation advised after emg and ncs?
The NCV/EMG is an electrophysiologic exam that can give results or patterns that are sometimes nonspecific or seen in a multitude of clinical conditions. Therefore the referring physicians whom has treated the patient over a period of time and has hopefully examined the patient many times and may know best which condition the NCV/EMG pattern discussed in the report best corresponds with, in his/her patient.
What are the two major types of EMG's?
Surface EMG & Needle EMG. Generally speaking, only needle EMG can be used for diagnostic purposes.
What is a twitch in electromyography?
electromyography is about muscle relaxers and contractions testing devise.
What can you have done instead of an MRI scan as you are scared to be put into small spaces?
There are some MRI machines that are open. Look around in your area to see if there is one available. In some cases, your doctor can prescribe medication to make you more relaxed during the test.
Do you have to both a NCV and an EMG?
If you have been referred to have an electrodiagnostic examination, that examination will normally involve both a nerve conduction study (NCS) & a needle EMG (nEMG). NCV is sometimes inappropriately used instead of NCS. Both parts of the examination (NCS & nEMG) are equally important in looking at different aspects of nerve and muscle function, and both should be performed. However, in some cases the clinician may determine that NCS or nEMG is contraindicated for some medical reason and may elect not to perform that part of the electrodiagnostic examination.

What happens if you receive a bad emg report?
The purpose of the EMG test primarily is to determine if there is a problem with a nerve or nerves, if there is a problem how bad that problem is and where that problem is. From this information interpretations and recommendations can be made that may include things like more testing, prescribing medication, physical therapy, bracing, injections, change in therapies, nutritional supplementation, &/or surgery or other medical procedures. You and your doctor may even decide to do nothing and just monitor your symptoms. The findings obtained can help you and your doctor decide the best course of treatment, but often the findings alone are insufficient and need to be correlated with your own history, physical examination, and other tests.
An EMG measures the electrical activity within the muscle by use of a sterile needle electrode, and there are many characteristics that an electromyographer can look at when evaluating an EMG. The activity within the muscle is recorded by the EMG machine and represented graphically on an electromyogram. This electromyogram measures the electrical activity of motor unit potentials within the muscles and represents them graphically on an X-Y axis. The X axis of the electromyogram represents time measured in milliseconds, and the Y axis of the electromyogram represents the amplitude of the motor unit measured in voltage. Because these electrical responses are represented in waves, those waves can be converted to sounds and listened to by the electromyographer. The examiner observing this activity can then make interpretations of the activity while watching and listening to the electromyogram. Often this begins with listening to the activity of the muscle with the needle moving in the muscle (called insertional activity), listening and observing to the activity of the muscle while it is at rest, listening and observing the motor unit morphology and recruitment patterns of the muscle with gentle contraction, and finally listening and observing the interference pattern of the muscle when it is at full contraction.
What are the benefits of having an EMG test?
The EMG test is used to assess the body's nervous system and make sure it is functioning properly. There is no waiting for the results to come in, as soon as the test is over, the doctor will have the results. A detailed report is sent to the attending doctor right away. This makes figuring out what is wrong a lot simpler and fast.
Why does the amplitude of the EMG signal and the force of contraction increase?
does the amplitude of the EMG signal and the force of contraction increase because a finite number of fibers or are fiting more often, or becasue more fibers are recruited to fire as the intensity of signals in the motorneurons increase, or a combination of the two?

If your on workers comp you must use a comp related doctor do the EMG and or NCV test. In many cases an approval must be sought from your adjuster. After 30 years of being a workers comp patient I've had some exposure to the red tape involved in workers comp. In most cases your carrier will approve a EMG doctor that your primary w/c doctor sends you to for the test. Keep in mind that some adjusters may say no. Then your attorney is forced to file a special form so an umpire type entity can determine whats fair. This would be an exception rather than a rule for an EMG is not an expensive test. Your adjuster may change over and over as time passes. If your adjuster will talk to you (many cold ones ask you to contact them through your attorney) be nice even if you want to curse him or her out. Workers comp is run much like an HMO only its more restrictive. Try you best to get along with your doctor. In Florida you can only change doctors ONCE in a lifetime. The workers comp system is way to restictive. One goal is to get you so frustated that you would rather settle than put up with the red tape. For example an adjuster could force you to go to court if you wanted or needed a particular procedure that they feel you don't need. Unless you have a nightmare adjuster your EMG test should be uneventfull. It doesn't make much sense to protest the doctor that you are sent to. The test is sorta cut and dried. The test results will be about the same. Like an EEG that you might get done for your heart and EMG will yield results that are what they are. For example lets say your a bit rude to the EMG doctor or tech. It want change the results of the EMG. Your main interest is how your nerves are conducting, not what opinion the EMG doctor has of you. Its like meauring your weight and height, they are what they are.
After birth, the bony orbits and eyes grow. If they are not the same size/shape, there can be assymmetries [differences in the two sides of the head].
Simply, dystocia is a misplacement of an eye, usually to high or too low. The brain may have problems in recognizing the difference, especially if it is changing. This can lead to double-vision, amblyopia, or dizziness. Dystocia is usually a birth defect.
Dystocia in adults can be due to tumor or thyroid condition or other things:

What would cause ulnar nerve damage not to show up on an EMG?
EMG's work on the same principle as an electrical wire and voltage transmission/measurement. Two probes are inserted, one at the top of the arm or the upper end of the nerve, the other one near the wrist before it goes past the wrist bone and into the pinky.
The upper probe is usually the transmission probe, the other the receiving. Since a specific, measurable amount of voltage is used, the voltage drop between probes can be measured and compared with established norms. Depending on the voltage drop between the probes, it will show how much actual nerve damage there is, or isn't. The reason no nerve damage is showing on the test is that there isn't enough voltage drop suggesting any real damage. If it were damaged, the drop would be measurable and comparable to established parameters. While it may have been slight, it obviously wasn't bad enough to be measurable.
Keep in mind that just because you have ulnar nerve pain doesn't mean it's damaged - in fact, if you have pain it means it's working well and something is compressing it elsewhere. For "elsewhere" I'd consider whether or not you've had any neck injuries, as arm nerves originate in the cervical spinal area. My own ulnar nerve constantly hurts due to injuries at the elbow, and major spinal damage in the neck which left permanent nerve damage.

During an EMG test, a fine needle is inserted into the muscle to be tested. This may cause some discomfort, similar to that of an injection. Recordings are made while the muscle is at rest, and then during the contraction.
What are the objectives of sales management?
help in good planning and proper allocation of resources
Sales management entails numerous objectives which are executed by sales managers. There are mainly three such objectives
- Sales Volume
- Contribution to profits
- Continuous Growth
The sales executives in this case are the ones who help implement these objectives. However it is the top management who has to outline the strategies to achieve these objectives of sales management. The top management should provide products which are socially responsible and are marketed in a manner which meets customers expectations and does not break it. Thus sales management involves a strong interaction between Sales, marketing and Top management.
Sales Management and financial results
Financial Results are another objective of sales management and are closely related and therefore sales management has financial implications as well.
Sales - Cost of Sales = Gross Profit
Gross Margin - Expenses = Net profit.
Thus the variation in Sales will directly affect the Net profit of a company. Hence maintaining and managing sales is important to keep the product / service / organization financially viable.
The Objectives of sales are therefore decided on the basis of where the organization stands and where it wants to reach. It is a collaborated effort from the top management along with the marketing managers and sales managers to provide with a targeted estimate.
Basically it is the narrowing of the spinal column due to a form of spinal injury or disease. It is common in elderly people, but can occur at any time in a person's life, especially if they have had a spinal injury. EMG is just a general term for Electromyography used to study the disease, I may be wrong so I apologize if that's the case. Mylopathy is the major problem. It can cause imbalnce problems, loss of motor skills, and in severe forms cause the patient to become bedridden or wheelchair bound. However, if caught early the chance for treatment is higher. This also depends on the person, some people have minor problems or progress slowly, while other have major problems or progress very quickly.
