What is electromyography?
Electromyography is a diagnostic test used by doctors to diagnose muscle disorders. An EMG involves inserting an electrode into a muscle in order to record its electrical activity. Your doctor might also use an audio amplifier to hear the electrical signal.
What is the nerve conduction study?
NCS measures the speed at which a nerve sends a signal electrically to a muscle. You can tell whether your nerves work properly by measuring the speed of the nerve signal. This helps your doctor determine if there is a problem in your nerves or in the way your muscles are responding to the nerve signal.
What are nerve conduction and EMG testing?
Both tests can help diagnose muscle and neurological disorders. If you are experiencing symptoms that may be related to a muscle or nerve problem, your doctor may order both tests at the same time.
NCS:
The provider will have you lie on a table, and insert an electrode with a small needle into the affected muscle. The provider will connect the wires with a machine which records electrical signals in your muscles at rest as well as when you are flexing them slightly.
The computer screen will display the electrical signals, allowing your doctor to check how well nerves communicate with your muscle. The monitor shows wavy and spiky traces to show the level of electrical activity within your muscle.
Your doctor will also ask you to do certain movements while the needle is in your muscle. You might feel a little pain with each insertion, but it's usually not uncomfortable.
What are needle electrodes?
The needle electrodes are needles that are attached to wires. The needle electrodes can be placed into muscles that are to undergo testing. Doctors will then move the electrodes around the muscle multiple times. When the needle electrodes are inserted, you may feel a sharp pain. The electrodes are then removed.
How is a test conducted?
During the assessment, you will first be asked relax. Then, specific movements will be required. For example, you might be asked to lift your arm, or to flex the wrist of your hand.
Your muscle will send an electrical signal that will be sent to the electrodes. The nerve signals will then be sent to your muscle. Your provider will then record the amount of time it takes for your muscle to respond to the nerve signal. This is called the conduction velocity.
What are some of the risks?
A bruise may appear when the electrodes with needles are placed into your muscle. This bruising is expected to disappear within a week. There may be some pain for a couple of days where the electrodes are inserted.

What does "public health" actually mean?
Public Health refers to the preservation and enhancement of the health status of the community. It involves preventing disease, injury, and disability, promoting good health practices; ensuring adequate nutrition; and controlling communicable diseases, environmental hazards, and behavioral risks.
What is the difference of a doctor and physician?
A doctor is someone who has completed their training and are licensed to practice medicine. A physician refers to a medical professional that specializes in one area of medicine.
What are your thoughts on the most pressing public health issues?
Many people suffer from obesity, diabetes, heart disease, and cancer. These conditions result in more deaths per year than AIDS combined with car crashes and murders. High blood pressure, strokes, asthma and arthritis are all caused by poor nutrition, exercise and smoking.
What will happen to Medicare if it isn't there?
Americans will become more uninsured. Some employers will terminate employees from their benefits plans. Many seniors will also have higher out-of pocket costs for prescription drugs or other medical services.
What are the main purposes of a health care system
The health care system must offer quality services and adequate medical facilities at an affordable cost to people who have a medical need.
This includes providing preventive care, encouraging healthy lifestyles and the appropriate treatment. It also means equitable distribution of resources in the health care system.
What role can I play in public healthcare?
Participating in prevention activities can help you protect your health as well as the health of others. Public health can be improved by reporting injuries and illnesses to health professionals, so that they can prevent further cases.
Statistics
- 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)
- The healthcare sector is one of the largest and most complex in the U.S. economy, accounting for 18% of gross domestic product (GDP) in 2020.1 (investopedia.com)
- The health share of the Gross domestic product (GDP) is expected to continue its upward trend, reaching 19.9 percent of GDP by 2025. (en.wikipedia.org)
- For the most part, that's true—over 80 percent of patients are over the age of 65. (rasmussen.edu)

What are the Key Segments of the Healthcare Industry?
The healthcare industry is made up of key segments such as medical devices, pharmaceuticals and diagnostics, biotechnology, therapy, health information technology, medical equipment, and other medical devices.
Defibrillators are blood pressure monitors, blood pressure monitors, stethoscopes or ultrasound machines that can be used to diagnose, prevent, or treat diseases. These devices are designed to diagnose or prevent disease.
Pharmaceuticals are drugs that are prescribed to treat disease or reduce symptoms. These include antibiotics.
Diagnostics are tests done by laboratories to determine illness or injury. Examples include blood tests, urine samples, CT scans, MRI scans, X-rays, etc.
Biotechnology refers the process of creating useful substances from living organisms such as bacteria. Examples include vaccines, insulin, and enzymes.
Therapeutics are medical treatments that treat diseases or alleviate symptoms. These treatments can include drugs, radiation therapy and surgical interventions.
Information technology for health is a category of computer software that helps physicians and their teams manage patient records. It helps doctors track what medications are being taken and when they should be taken.
Medical equipment is anything used to diagnose, treat, or monitor conditions or illnesses. Dialysis machines, pacemakers and ventilators are just a few examples.
