What is electromyography?
Electromyography (EMG) is a test that helps doctors diagnose muscle problems in the body. During an EMG, a needle with an electrode is inserted into one of your muscles to record its electrical activity. You doctor may use an audio amplifier device to listen to a muscle's electrical signals.
What is the Nerve Conduction Study?
Neuroconduction studies (NCSs) measure the speed with which a neuron sends an electric signal to a muscular. You can tell whether your nerves work properly by measuring the speed of the nerve signal. It helps doctors diagnose whether there's a problem with either your nerves of the way you respond to nerve signals.
What is nerve conduction testing and EMG?
Both of these tests help to diagnose a wide range of muscle and neurologic disorders. You may have both tests ordered at the same if your symptoms seem to be related to muscle or nerve 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 or she will then connect the wires to a machine that records your muscle's electrical signals at rest and while you are slightly flexing it.
The electrical signals can be seen on the computer screen. Your doctor can then see how effectively nerves transmit messages to muscles. The monitor shows wavy and spiky traces to show the level of electrical activity within your muscle.
You may also be asked to perform certain movements by your doctor while the needle remains in your muscle. You might feel a little pain with each insertion, but it's usually not uncomfortable.
What are needle electrodes?
These needle electrodes consist of wires and needles. The doctor inserts the needle electrodes into the muscles to be tested and moves them around several times. A sharp, quick pain may be felt when the electrode needle is inserted in your muscle. The needle electrodes are removed after the test is done.
How is a test conducted?
During the assessment, you will first be asked relax. Then, specific movements will be required. For instance, you may be asked by the test to lift your arm or to flex your hand's wrist.
Your muscle will send an electrical signal that will be sent to the electrodes. The nerve signals will then be sent to your muscle. The provider will then measure the time it takes for the muscle to respond to a nerve signal. This is called conduction velocity.
What are the risks involved?
When the electrodes are inserted, you may experience a bruise. This bruising usually disappears within a few weeks. For a few days, you may feel soreness where the electrodes were placed during EMG.
FAQ
What are the primary goals of a health care system?
Three of the most important goals for a healthcare system are to provide quality care at a reasonable cost, improve health outcomes, reduce costs, and help patients.
These goals were combined into a framework named Triple Aim. It's based on the Institute of Healthcare Improvement (IHI) research. This was published by IHI in 2008.
This framework aims to ensure that we all focus on the same goals and can achieve each goal while not compromising other goals.
This is because they aren't competing against one another. They support each other.
For example, improving access to care means fewer people die due to being unable to pay for care. This reduces the cost of care.
It is also important to improve the quality and cost of care. It also improves the outcomes.
What should you know about vaccines
Vaccines can be very effective and safe ways to stay healthy. Vaccines provide immunity against certain diseases. Vaccinations are typically given at certain times in childhood, adolescence or adulthood. Your doctor will help you decide when is the best time to get vaccines.
What is a health care system in public health?
The entire process of providing medical services to the population is called Health System. It includes service delivery, financing, regulation, research, education, training, and information systems.

- Price Increases, Aging Push Sector To 20 Percent Of Economy". (en.wikipedia.org)
- Foreign investment in hospitals—up to 70% ownership- has been encouraged as an incentive for privatization. (en.wikipedia.org)
- For instance, Chinese hospital charges tend toward 50% for drugs, another major percentage for equipment, and a small percentage for healthcare professional fees. (en.wikipedia.org)
- About 14 percent of Americans have chronic kidney disease. (rasmussen.edu)
- Over the first twenty-five years of this transformation, government contributions to healthcare expenditures have dropped from 36% to 15%, with the burden of managing this decrease falling largely on patients. (en.wikipedia.org)

What are the key segments in the Healthcare Industry?
The healthcare industry includes the following key segments: diagnostics/biotechnology, pharmaceuticals/diagnostics, therapeutics/health information technology, medical device, and equipment.
Blood pressure monitors, defibrillators and stethoscopes are all medical devices. These products are used to diagnose and prevent or treat disease.
Pharmaceuticals are medications that are used to treat or alleviate symptoms. Antibiotics, antihistamines (or contraceptives), are just a few examples.
Diagnostics are laboratory tests used to detect illness and injury. There are many types of diagnostics: blood tests; urine samples; CT scans; MRI scans; X-rays.
Biotechnology refers the process of creating useful substances from living organisms such as bacteria. These include insulin, vaccines and enzymes.
Therapeutics are medical treatments that treat diseases or alleviate symptoms. These treatments can include drugs, radiation therapy and surgical interventions.
Health information technology includes computer software programs that help physicians, and their teams manage data related to patient records. It helps doctors and their teams track which medications are being used, when they should have been taken, and if they work properly.
Any equipment used to diagnose, treat or monitor illnesses or conditions is medical equipment. Dialysis machines are dialysis tables, pacemakers ventilators, operating rooms, and other medical equipment.
