Table 4 Small intestinal transit patterns during fast

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

  ON-OFF group OFF-ON group p
Proportion of time with fast movements (percentage) -8 (-27, 53) 20.5 (-25, 55) 0.18
Distance covered during fast movements (cm) 0 (-7, 5) 2 (-5, 6) 0.09
Proportion of time with slow movements (percentage) -2 (-53, 40) -16 (-60, 35) 0.44
Distance covered during slow movements (cm) -3 (-31, 10) 2.5 (-13, 22) 0.18
Proportion of time with very slow movements (percentage) 5 (-93, 12) 1 (-13, 7) 0.08
Distance covered during very slow movements (cm) 5 (-12, 32) -5 (-23, 16) 0.06
  1. 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.
  2. 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.
