Figure 4

Progression of the magnetic pill over time during fast. Investigation made in fasting conditions. Pyloric passage, 2 hour after pyloric passage, and ileocecal passage is marked. The color of the plot represents different velocities (red: > 15 cm min-1, blue: < 15 cm min-1, black: < 1.5 cm min-1). The contractions frequency can only be calculated when progression is very slow (< 1.5 cm min-1). Most distance through the small intestine is covered during the period just after pyloric passage and during the period just before ileocecal passage. These two periods, separated by approximately 90 minutes, probably reflect phase III of the MMC.
