Electromyography (EMG) is a new groundbreaking technology hitting the fitness industry. EMG is used not only in the healthcare industry, but also in the medical profession. EMG is related to the examination of muscles with small electrodes inserted into the abdomen of small muscles.
Throughout this report, EMG will be facilitated to understand the basics, so that the general public can have a fair idea of electromyographical research and its benefits for general health and well-being.
What are EMG tests used for?
Doctors use EMG to diagnose medical conditions directly associated with muscular dystrophy and myasthenia gravis. In the clinic, IMGs are also used to identify nerve disorders such as paralysis, involuntary glare, or muscle weakness. While doctors use EMG research for a variety of reasons to differentiate between neurological disorders or muscle disease physiologists.
Physiologists use EMG research and results to determine which exercises cause the most electrical stimulation in a particular muscle. The higher the arousal, the more muscle fibers are recruited thus increasing the size and strength of the muscles.
Why is there an EMG test?
Sometimes people who undergo hip replacement or knee surgery and have their legs reversible for a long time after being on a crutch or cast. The patient then begins to train again and even though the leg has regained its size it still feels really small and relatively weak. Doctors will perform EMG tests and see how much electrical activity is going on, if there is no more activity the client may need to be referred to a specialist. If the test comes back as a penalty, the client needs to do more exercises to strengthen the affected muscles by doing additional exercises.
What is included in the test?
EMG on you. Before the test, the doctor requests that the patient not drink alcohol, smoke or caffeine for twenty-four hours, as all of these substances affect the amount of electrical activity inside the muscle. For example, caffeine and smoking speed up the signals while alcohol has the opposite effect.
In the EMG test the patient undergoes surgery and rests on a bed. The doctor will then place a small flat disc (approximately 4 cm wide) near the muscle that is being tested. A small needle (with an electrode at the tip) is then tested through the skin and into the muscles. The needle is used less than a normal syringe but the patient feels a slight discomfort in inserting. At the top of the needle is a small wire that points from the needle to the monitor (oscilloscope) and then the monitor looks similar to the life line but shows how much electrical activity is going through the more scattered line graph. To get really good electrical stimulation, the doctor may ask the patient to contract and relax the muscle.
What do the results mean?
If, while looking at the monitor, there is a lot of movement and the graph of the line is going up and down like some crazy thing, it means that there is a lot of stimulation going on inside that muscle. On the other hand if the muscle does not get much activity while contracting and relaxing, this means that you will get a negative result.
If negative, the doctor will have to refer the patient to a specialist who can diagnose the problem.
What are the risks?
The only risk associated with an EMG test is an infection at the needle insertion point or throat muscle for the next few days. However, these hazards are unlikely to occur because the test is performed in a hospital environment where everything is sterile and then cleaned.
If patients later become frightened by the pain in the muscles, doctors recommend ice the muscle reaching home to reduce the swelling caused by the needle insertion.
