Electromyography (EMG): What Is It, and Does It Hurt?

Written by Gary Cordingley


Continued from page 1

Why would this be inflicted upon you inrepparttar first place? Usually it's because your own doctor thinks you might have a nerve or muscle condition and wants to narrow downrepparttar 141643 possibilities, seek confirmation, or eliminate a particular diagnosis.

Electromyography is a term meaning "electrical muscle recording." Because muscle is an electrical tissue,repparttar 141644 needle electrode inrepparttar 141645 muscle, when connected to an amplifier and an oscilloscope screen, can showrepparttar 141646 muscle's electrical activity as a series of voltage-fluctuations. Moreover,repparttar 141647 signal is also fed through a speaker, so you andrepparttar 141648 electromyographer can listen to whatrepparttar 141649 muscle has to say. Each muscle is analyzed while you tense it, and again while you relax it.

Normal muscles display typical patterns torepparttar 141650 eye and ear throughrepparttar 141651 oscilloscope and speaker. Abnormal muscles show altered patterns. Sometimesrepparttar 141652 abnormality is more evident onrepparttar 141653 oscilloscope, and sometimes more evident onrepparttar 141654 speaker. Muscles that are themselves sick (myopathy) show one pattern, while muscles that are connected to sick nerves (neuropathy) or spinal roots (radiculopathy) can show yet another pattern.

Electromyography is often paired with nerve conduction studies performed atrepparttar 141655 same testing session byrepparttar 141656 same doctor and withrepparttar 141657 same equipment. Each test—EMG and nerve conduction studies—has its own story to tell, as well as its own strengths and weaknesses in its ability to show signs of disease. The results ofrepparttar 141658 electromyography and nerve conduction studies are considered together to come up with a more complete, combined test-outcome and report.

The time required for testing can depend onrepparttar 141659 nature ofrepparttar 141660 problem. Also,repparttar 141661 electromyographer might add or subtract additional testing depending on howrepparttar 141662 initial components turn out. Overall, a typical session might last between 45 and 90 minutes. That doesn't mean thatrepparttar 141663 patient is subjected to unpleasantries during that whole period of time. Actually, much ofrepparttar 141664 time is devoted to getting allrepparttar 141665 little pieces and parts of equipment organized and in place for each "mini-test" comprisingrepparttar 141666 overall testing session.

So when your doctor refers you for electromyography, don't listen to your brother-in-law. What does he know anyway? (Wait a minute, I'm somebody's brother-in-law, too! But you getrepparttar 141667 idea.) As an adventure, EMG is less than it's cracked up to be. As a diagnostic test, it can be very useful.

Arthritis-Fighting Drugs: The Ulcer Connection

Written by JR Rogers


Continued from page 1

The Use of NSAID's andrepparttar Stomach When you are using an NSAID of any kind, it holds backrepparttar 141602 ability of your body to produce prostaglandins that protect both your stomach and inflammation. In short, it inhibits your body's ability to offer this protection. So, do you have to suffer with arthritis pain or riskrepparttar 141603 ulcer?

You have Two Options Available If you feel you must use an NSAID, and I caution against them, then you should use a product like Prilosec (an over-the-counter antacid); or, Prevacid or Nexium (prescription). These drugs reducerepparttar 141604 production of acids and if taken atrepparttar 141605 same time as an NSAID, reducerepparttar 141606 ulcer risk.

Frankly, I am a strong advocate of using a pharmaceutical quality liquid glucosamine. Most osteoarthritis sufferers get great results and there is absolutely no ulcer risk involved. Certainly, there is no risk of cardiac problems associated with using liquid glucosamine.

The choice seems easy to me.
