myoelectric

The electrical signals within the human body that stimulate the muscles to move. The signal, which is less than one millivolt, has an average frequency of about 100Hz. Myoelectric signals are used to move prosthetic limbs. The faint signals are detected and amplified to control the battery-driven, moving elements of the prosthesis. The word myo comes from the Greek "myos" and means "muscle."

Myoelectrical signals were recorded simultaneously from 4 muscles by Biometric/Data-link 8 channel surface electromyogram (in this paper, UTL stands for upper trapezius left, UTR for upper trapezius right, MDL for middeltoid left, and MDR stands for mid-deltoid right).

In order to observe the purposed movement to tetanic stimulus, we could not give the muscle relaxants until intubation, but BIS will be infulenced by myoelectrical activity, that might be a reason why BIS [sub]50 at LOS was higher than that at LOC.

Aging may result in progressive loss of myoelectrical activity along the fallopian tubes.
On the other hand, as pregnancy progresses the uterine myoelectrical activity shifts towards higher frequencies and becomes more organized [3, 32]; therefore pregnancy contractions would also present some differences in the characteristic parameters used in this study; still they would be expected to remain different enough from those of artifacted signal windows.
Normal myoelectrical activity of the uterus is greater during calving and decreases significantly around seven to nine days postpartum (Gajewski and Faundez, 1992; Gajewski et al., 1999).
Mechanisms implicated in these functional derangements include inflammatory, myoelectrical and neuroendocrine processes as well as numerous clinical conditions and treatment approaches.

McGregor, (2001), in a study of 19 rowers and 20 control subjects (almost identical in terms of age, body height and weight), have found that asymmetric myoelectrical activity observed between right spinal extensor muscle and left spinal extensor muscle, necessary to execute extension movement, significantly correlates with the part in which the rower is paddling.
