ELECTROMYOGRAPHY Meaning and
Definition
-
Electromyography (EMG) is a diagnostic medical technique that involves the measurement and evaluation of the electrical activity generated by skeletal muscles. It is a specialized test used to assess the health and functionality of muscles and the nerves controlling them.
During an EMG procedure, small electrodes attached to the skin surface or inserted directly into the muscle tissue detect and record the electrical signals produced by the motor units inside the muscles. The recorded data is then amplified, filtered, and displayed on a monitor or printed on paper for further analysis.
The primary purpose of electromyography is to evaluate muscle activity and determine whether it is normal or abnormal. Abnormal muscle activity may imply certain neuromuscular disorders, nerve damage, muscle diseases, or problems with the motor neurons. This diagnostic procedure can help identify conditions such as muscular dystrophy, myasthenia gravis, peripheral neuropathy, and nerve compression syndromes like carpal tunnel syndrome.
Electromyography plays a crucial role in the field of clinical neurophysiology, providing valuable information to physicians and specialists in diagnosing and understanding various neuromuscular conditions. By interpreting the collected data, medical professionals can determine the severity and location of muscle or nerve damage, develop appropriate treatment plans, track the progression of diseases, and monitor the effectiveness of interventions such as physical therapy or medication.
Common Misspellings for ELECTROMYOGRAPHY
Etymology of ELECTROMYOGRAPHY
The word "electromyography" has its roots in two components: "electro-" and "myography".
1. "Electro-" comes from the Greek word "ēlektron", which means "amber" or "electron". In ancient times, it was discovered that rubbing amber could generate static electricity, and the word "electro-" came to be associated with electricity.
2. "Myography" is derived from the Greek word "myo-" which means "muscle" and the suffix "-graphy" which means "recording" or "measurement". Therefore, "myography" refers to the recording or measurement of muscles.
Combining these components, "electromyography" refers to the recording or measurement of electrical activity in muscles.
