Fig. 3. Three-dimensional (3D) representative manometric traces from a patient during simulated evacuation before/after the biofeedback therapy (BFT). (A) Pre-BFT surface plot of pressures in patients who failed the balloon expulsion test. (B) Pre-BFT 3D pressure cylinder manometric traces in patients who failed the balloon expulsion test. (C) Post-BFT surface plot of pressures in patients who passed the balloon expulsion test. (D) Post-BFT 3D pressure cylinder manometric traces obtained from a patient who passed the balloon expulsion test. (A, C) X-axis, Y-axis, and Z-axis depict the time (seconds), distance from the anus (cm), and pressure (mmHg), respectively. (B, D) X-axis and Y-axis represent the pressure (mmHg) along the 4 cardinal directions (north, south, east, and west), and the Z-axis represents the distance from the anus (cm).
