Anatomic Planes

Anatomical position, the crown diameter than the body vertical plan in order to lead to earlier segments of / back cover. Horizontal or axial plane of the diameter than the body leads to rostral tail / "sectoral" segments. Axial or sections in this presentation, the convention is to look at a rostral (or vice versa). Sagittal plane extends the previous subsequent breakdown within the body vertical to the left and right segments.


This program puts emphasis on the location of the intramuscular needle electrodes for direct recording of myogenic signals. The two most usually used is the concentric needle electrodes and monopolar needle electrodes. Other less commonly used are single fiber electrodes for EMG electrodes and motion study of fiber density, macro-EMG electrode is used to study macro-EMG and fiber density, and intramuscular needle electrode, which is both myogenic data signals and allow therapeutic injections chemodenervation muscle. Etc., that this program is not synonymous with surface electrode recording during the studies of engine power. Some of them are considered a special relationship to this program.

Isometric contraction

This is the most common form of contraction or the model used as the EMG activation the tension on the muscle via activation without altering its length. So there are fewer chances of accidental needle electrodes into muscle movement. Although the standard length of the isometric contraction of the muscle EMG does not seem to change the surface observations in clinical practice, the needle electrode may bow or bend in some muscles (e.g., anterior tibial, flexor carpi radialis, etc.). In these muscles, it is appropriate to activate the muscles before getting the needle electrodes in an oblique direction (perpendicular to the preferred approach). Resting on activity, can be examined later when the muscles are relaxed.
