Averaged peak contraction amplitudes in the three subject groups. Amplitudes overall were lowest in the GERD group and highest in the acid sensitive group. While amplitudes were similar between segment 2 and segment 3 in GERD subjects and controls, values were significantly higher in segment 3 in the acid sensitive group.
