Mechanomyogram
Mechanomyogram (MMG)
Mechanomyogram (MMG) is a technique used in biomedical research and clinical diagnosis to measure the mechanical activity of muscles. Pronounced as "me-ka-no-my-o-gram", the term is derived from the Greek words "mechane" (meaning machine), "myo" (meaning muscle), and "gramma" (meaning something written).
Overview
The Mechanomyogram is a recording of the oscillations of a muscle during contraction. It is a non-invasive method that provides information about the mechanical characteristics of muscle contraction. The MMG signal is obtained by placing an accelerometer, a microphone, or a laser displacement sensor over the skin surface above the muscle of interest.
Applications
The MMG has been used in various fields such as physiology, rehabilitation, sport science, and neurology. It is particularly useful in the study of muscle fatigue, muscle disorders, and the evaluation of muscle performance.
Advantages and Limitations
The main advantage of the MMG is that it provides a direct measure of the mechanical activity of the muscle. However, it has some limitations. The MMG signal is affected by the anatomical characteristics of the muscle and the surrounding tissues, and it is sensitive to the sensor's position and orientation.
