Fig. 5. Metrics from esophageal high-resolution manometry used in the evaluation of contraction reserve. (A) The vigor of esophageal body contraction is assessed using the distal contractile integral (DCI). (B) The vigor of esophageal body contraction following inhibition of peristalsis during the repetitive swallows by multiple rapid swallows (MRS) provocative test. The DCI of contraction following MRS is higher than the mean DCI from test swallows (post-MRS: wet swallow DCI ratio > 1) indicates contraction reserve.
