What is Electromyography (EM)?
Electromyography (EMG) is a test that helps doctors diagnose muscle problems in the body. During EMGs, a needle fitted with an electrode is inserted to record electrical activity in one of your muscles. Your doctor may also use a device called an audio amplifier to hear the muscle's electrical signal.
What is the nerve conduction study?
NCS measures the speed at which a nerve sends a signal electrically to a muscle. The speed of this nerve signal can be used to tell if your nerves are working properly. This helps doctors find out whether you have a problem with your nerves or with the way your muscles respond to the nerve signals.
What are nerve conduction EMG tests?
Both tests can help diagnose muscle and neurological disorders. Both tests may be ordered by your doctor if symptoms are caused by muscle or nervous problems.
NCS:
You will lie down on the table and your provider will insert a needle with an electrode into the muscle that is affected. He will then connect wires to a device that records the electrical signals of your muscle at rest, and also when you are flexing slightly.
The electrical signals will be displayed on a computer screen, and your doctor can see how well the nerves are sending messages to your muscle. The monitor also displays wavy, spiky and other lines that indicate how much electrical activity there is in your muscles.
You may also be asked to perform certain movements by your doctor while the needle remains in your muscle. Although you may feel some discomfort with each needle insertion, it is usually not painful.
What are the needle electrodes used for?
These needle electrodes consist of wires and needles. The doctor places the needle electrodes in the muscles which need to be checked, and then moves them several times around the muscle. A sharp, quick pain may be felt when the electrode needle is inserted in your muscle. After the test, you will remove the needle electrodes.
How does the test work?
During this test, you are asked to relax first and then perform certain movements. For example, you might be asked to lift your arm, or to flex the wrist of your hand.
When you move your muscle, it will send a small electrical signal to the electrodes, which will then send a nerve signal to your muscle. Your provider will record the time taken for your muscle's response to the nerve signals. Conduction velocity is what we call it.
What are the possible risks?
You might experience a bruise when the needle electrodes are inserted into your muscle. This bruising will disappear in a few days. For a few days, you may feel soreness where the electrodes were placed during EMG.

What should I know regarding immunizations
Immunization refers the process of activating an immune response in response to a vaccine. The body responds to the vaccine by making antibodies (immunoglobulins) that protect against infection.
What is an infectious disease?
An infectious disease is caused either by bacteria, viruses, parasites or both. Infectious diseases spread quickly through close contact. Mumps, rubella (German Measles), whooping cough, rubella (German Measles), measles and mumps are some examples.
What are the different types of health insurance?
There are three main types of health insurance:
-
Private health insurance covers most costs associated with your medical care. You pay monthly premiums for this type of insurance, which is usually purchased directly from private firms.
-
Although most medical costs are covered by public insurance, there are certain restrictions. Public insurance does not cover preventive services, routine visits to doctors, hospitals and labs, Xray equipment, dental offices, prescription drugs or certain tests.
-
The medical savings account (MSA) is used to help you save for future medical expenses. The funds are kept in a separate account. Most employers offer MSA program. These accounts are tax-free, and they accumulate interest at rates similar to bank savings accounts.
What are the most critical issues that public health faces today?
Many people are suffering from diabetes, obesity, heart disease, cancer, and heart disease. These conditions result in more deaths per year than AIDS combined with car crashes and murders. Poor diet, inactivity, and smoking all contribute to high blood pressure and stroke, asthma, arthritis and other conditions.

How To
What is the Healthcare Industry Value Chain
The entire value chain of the healthcare industry includes all activities involved with providing healthcare services to patients. This includes all business processes at hospitals and clinics. It also includes supply chains that connect patients to other providers like pharmacists and insurance companies. The result is a continuum which starts with diagnosis and ends in discharge.
The four key components of the value chain are:
-
Business processes - These are the tasks performed throughout the whole process of providing health care. A physician might order medication for a patient, then perform an examination. Every step must be done efficiently and accurately.
-
Supply Chains are all the organizations responsible for making sure the right supplies reach their intended recipients at the right time. A typical hospital has dozens of suppliers, including pharmacies, lab testing facilities, imaging centers, and even janitorial staff.
-
Networked Organizations - To coordinate these various entities, there must be some form of communication between the different parts of the system. Hospitals often have several departments. Each one has its own phone number and office. Employees will be able to access a central point for information and updates in every department.
-
Information Technology Systems- IT is vital in ensuring smooth business processes. Without it things would quickly fall apart. IT can also be used to integrate new technologies into a system. Doctors, for example, can connect to a secure internet connection to access electronic medical records.
