[Cutaneous electro-gastroenterography for evaluation of changes in the gastrointestinal tract in consequence of various angles of inclination and length of head-down tilt].
Experimental results were compared with data of cutaneous electro-gastroenterography and USI of the gastrointestinal tract in human subjects at different tilt angles and after different periods of tilting. It was shown that increased GIT electrical activity in tilted subjects before meal is representative of increasing intracavetary contents of the stomach and small intestine. More intensive electrical activity results from elevation of the GIT tone and peristalsis. Extension of tilt duration raises GIT tone and peristalsis and, consequently, stimulates the GIT electrical activity. Further increase of the tilt angle suppresses evacuation and, therefore, the electrical activity Analysis of the results allows conclusion that increased parameters of the total energy of GIT electrical potentials are reflective of elevated tone of GIT walls, whereas elongation of the potential peaks envelope implies activation of peristalsis.
