Design outcomes
Primary
| Measure | Time frame |
|---|---|
| UES relaxation time. The item mentioned above is evaluated at catheterization. | — |
Secondary
| Measure | Time frame |
|---|---|
| The maximum pressure in the velopharynx and maximum pressure in the meso-hypopharynx were measured during swallowing. The maximum pressure in the UES at the start of the swallowing motion. The minimum pressure after the swallowing motion. The maximum UES pressure after the pressure waveforms in the velopharynx and meso-hypopharynx disappeared. The durations of pressure above baseline in the velopharynx and meso-hypopharynx regions. The time from the point at which the UES pressure started to increase until it reached the maximum pressure at the start of the swallowing motion. The time from when the UES pressure reached the maximum pressure until completion of the gradual decrease, after the waveforms in the velopharynx and meso-hypopharynx disappeared. Change of the measurement values above-mentioned by the amount of volus. The number of the measurement to establish reliable deglutition pressures. | — |
