Demographics
| Number (n = 129) | |
|---|---|
| Patients’ characteristics | |
| Female patients | 91 (71%) |
| Age (years) | 57 (18–81) |
| Anal electrosensitivity | |
| At 2 cm (mA) | 6 (2–20) |
| Anorectal pressure test | |
| Basal puborectal pressure (mmHg) | 10 (5–50) |
| Voluntary contraction (mmHg) | 40 (5–185) |
| Balloon retention test | |
| Pressure at start (mmHg) | 25 (5–185) |
| Involuntary contraction (mmHg) | 130 ± 59 |
Voluntary contraction is the pressure at the level of the puborectal muscle contraction during maximum squeeze. Involuntary contraction is the pressure at the level of the puborectal muscle during maximal tolerable volume or maximal retainable volume.
