Phonomyography
Phonomyography
Phonomyography (pronunciation: /ˌfəʊnəʊmaɪˈɡrɑːfi/), also known as acoustic myography, is a technique used in medicine to record the sounds produced by muscle contraction. The term is derived from the Greek words 'phone' (sound), 'myo' (muscle), and 'graphia' (writing).
Etymology
The term "Phonomyography" is derived from three Greek words: 'phone' meaning sound, 'myo' meaning muscle, and 'graphia' meaning writing. Thus, it literally translates to "writing the sound of muscles".
History
Phonomyography was first introduced in the 1970s as a non-invasive method of measuring muscle activity. It has since been used in various fields of medicine, including anesthesiology, neurology, and rehabilitation medicine.
Technique
In phonomyography, a microphone is placed over the muscle of interest. The sound produced by the muscle contraction is then recorded and analyzed. This technique is particularly useful in assessing the function of peripheral nerves and muscles.
