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.

Does someone know if you have to let a comp doctor perform an emg and ncv on you himself or do you have the right to have another doctor do it and give comp the report?

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.

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.

You think one call-workers comp people paid emg ncv medical doctor to give an inaccurate test result How would you prove that Are there medical doctors that would actually release false test results?

You can't really prove it, but you can have their test results disputed. If you have another independent test performed (you'd have to pay for it or get a lawyer to deal with it), and those test results dispute the others, you could then establish a legal challenge to their data.Your best option is probably to get an independent analysis done, then if it disputes the other report, get a lawyer to sort it out. You should ALWAYS have a Lawyer when dealing with Comp issues or you will get screwed - period.I am a physician who has previously contracted with One Call Medical. They never influence the results. One Call Medical makes the same amount of money no matter how the results turn out for you, they are a broker, they simply connect your employer's work comp carrier with doctors who perform EMG/NCS. However, there are other factors that could influence your results. One Call Medical pays less for their EMG/NCS than if the insurer contacted the testing physician directly. One Call Medical also typically does not pay for more elaborate testing and will pay the bare minimum number of tests. THose of us who are well trained in EMG/NCS often drop One Call Medical because they pay so poorly and will not pay for more elaborate EMG/NCS unless you write letters of need with long explanations. Sooooo, typically in the area I practice, the hungriest physicians, or the physicians that feel comfortable spending THE LEAST TIME performing the test are the ones that stick with One Call Medical. If you really want to know if your EMG/NCS was inaccurate, forget the test performed by One Call Medical and pay for your own test with a skilled and experienced examiner who is board certified to perform EMG/NCS testing specifically (there is a board certification for this test). Being board certified in neurology does not guarantee you are highly skilled at EMG/NCS. Also consider seeing a physiatrist, often these doctors conduct more detailed EMG/NCS.
