The record is called an electromyogram. EMG detects the electrical potential generated by muscle cells, when these cells are electrically or neurologically activated.
To test predictions of the functional role of the circular muscle zones during swimming, electromyograms (EMGs) in conjunction with video footage were recorded from brief squid Lolliguncula brevis (5.0-6.8 cm dorsal mantle length, 10.9-18.3 g) swimming in a flume at speeds of 3-27 cm [s.sup.-1].
While physical examination and other studies, including X-rays, electromyograms, nerve conduction velocity studies, and thermography, may document an organic basis in many cases of chronic back pain, some organic syndromes defy definition by objective tests.
We evaluated the activity pattern of finger flexor muscles and finger force exertion and the relationship between keyboard reaction forces and electromyograms (EMGs) while keying.
Physiologists call readings from muscle signals electromyograms (EMGs).

Julien Penders, who developed the system, says it can also work with other low-power medical sensors, such as electroencephalograms (EEGs) to monitor neurological conditions or electromyograms to detect neuromuscular diseases.

Electromyograms (EMGs) were recorded from fish swimming at speeds ranging from 1.5 to 3 body lengths (BL) per second at 10 [degrees] C ([approximately]30 to 60 cm [s.sup.-1]) and from 2.5 to 4.25 BL per second at 20 [degrees] C ([approximately]50-85 cm [s.sup.-1]).
