Learn about Electromyography (EMG), the test used to diagnose muscle pain and dysfunction effectively.
792 views
The name of the test for muscle pain is an Electromyography (EMG). This test assesses the health of muscles and the nerve cells controlling them. EMG helps diagnose conditions causing muscle weakness, pain, or dysfunction. The procedure involves small electrodes that measure electrical activity in muscles at rest and during contraction.
FAQs & Answers
- What symptoms indicate that I should get an EMG test? Symptoms that may indicate the need for an EMG test include persistent muscle weakness, unexplained pain, numbness, tingling sensations, or muscle cramps.
- How is an EMG test performed? An EMG test involves placing small electrodes on the skin or inserting thin needles into the muscles to record electrical activity while the muscles are at rest and during contraction.
- How long does an EMG test take? Typically, an EMG test takes about 30 minutes to an hour, depending on the number of muscles being tested and the complexity of the assessment.
- Are there any risks associated with an EMG test? EMG tests are generally safe, but possible risks include bruising, soreness at the electrode insertion sites, or, in rare cases, infection.
