The invention concerns a method which consists in: causing the subject to swallow at least one emitting element (E) ingestible but non-digestible comprising means transmitting at a given fixed frequency; measuring, at a given time using at least three reception means (R1, R2, R3) distributed around said subject's trunk, the phase shift of the frequency transmitted by said transmission means relative to a reference phase; determining by triangulation on the basis of the three phase-shift measurements the position of said element; defining based on the position of said element a digestive motility and/or passage data. Thus, it is possible to assess: gastric emptying time, gut and colic motility; depending on the weight of the transmitter, gastric, intestinal and colic activity and propulsive force of the stomach, the bowel and the colon; the length of the small intestine and of the colon. |
