Figure 9.27 Endurance Squeeze test
The letters between square brackets refer to the corresponding letters in the
above figure.
During the endurance squeeze test, the patient squeezes their External Anal
Sphincter and maintains the squeeze for about 30 seconds. The beginning
and ending of the squeeze period are marked with two squeeze markers [A]
and [B], as shown in Figure 9.27. The software will automatically insert two
channel markers [C] and [D]. The first channel marker will be placed on the
maximum EAS pressure between marker [A] and [B]. The second channel
marker will be placed at a specified squeeze time after the first channel
marker. The positions of the channel markers mark the exact EAS pressures
which are used for the result calculations. They can be repositioned by the
user, if they are not correctly placed by the software.
The software will calculate following results for each marked endurance
squeeze:
• Maximum pressure
• Squeeze time
• Pressure after squeeze time
• Fatigue slope
• Average squeeze pressure
• Area under the curve
