Single contraction patterns with no significant progressive movement of the unit were most prevalent in the stomach and the rectosigmoid colon. During the continuous contraction patterns, the unit moved in an antegrade or retrograde direction. Longer distance and higher velocity were seen during antegrade than during retrograde movements. The motility indices (as measured with WMC) in combined ascending, transverse and descending colon showed a positive linear association (\n                      <jats:italic>r<\/jats:italic>\n                      \u00a0=\u00a00.7) to the capsule movements (as measured with 3D\u2010transit).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions &amp; inferences<\/jats:title>\n                    <jats:p>The combined system provides synchronous information about movements and gut contractions.
