A randomised, controlled study of small intestinal motility in patients treated with sacral nerve stimulation for irritable bowel syndrome

Table 4 Small intestinal transit patterns during fast

Proportion of time with fast movements (percentage)	-8 (-27, 53)	20.5 (-25, 55)	0.18

Most of the distance covered by the magnetic pill during the first hour after pyloric passage occurred during short bursts of fast movement only accounting for a small proportion of the time. This was unaffected by SNS.
Fast movements (>15 cm/min), slow movements (between 1.5-15 cm/min), and very slow movements (<1.5 cm/min). Values are expressed as median change and range.
