Trial Outcomes & Findings for Postpartum Pelvic Floor Muscle Training in Women With and Without Injured Pelvic Floor Muscles (NCT NCT01069484)

NCT ID: NCT01069484

Last Updated: 2016-12-01

Results Overview

Urinary incontinence was assessed by The International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form (ICIQ-UI Short Form questionnaire, www.iciq.net). Women were considered as incontinent if they reported to leak urine (yes/no) at any frequency.

Measure
Postpartum Pelvic Floor Muscle Training
Beyond the customary leaflet (received from the postnatal ward) and the thorough initial instruction on how to contract the pelvic floor muscle (PFM) correctly, the training participants attended a supervised exercise class once a week led by an experienced physiotherapist and were prescribed daily home training over a period of 4 months. The PFM exercise protocol followed general principles for strength training; 3 sets 8-12 contractions close to maximum (Bø et al 1990, Haskell 2007). The participants are provided with a DVD of the program (www.corewellness.co.uk). Training adherence at home was recorded in a training diary whereas the physical therapist recorded group session adherence. Training participants were continuously motivated by the physical therapist to keep up their adherence to training classes and home training, and high performance during training was strongly emphasised.
Control
Beyond the customary leaflet (received from the postnatal ward) and the thorough initial instruction on how to contract the PFM correctly, the control group participants received no further intervention. They were not discouraged from doing PFMT on their own.

PRIMARY outcome

Timeframe: 6 months postpartum (end of intervention)

Population: Primiparous women who delivered a singleton baby vaginally after more than 32 weeks of gestation. They had to have Scandinavian language skills, no severe perineal tearing, no prior abortion or stillbirth after 16 weeks of gestation, and no illnesses interfering with the ability to follow-up.

Urinary incontinence was assessed by The International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form (ICIQ-UI Short Form questionnaire, www.iciq.net). Women were considered as incontinent if they reported to leak urine (yes/no) at any frequency.

Measure
Postpartum Pelvic Floor Muscle Training
n=87 Participants
Beyond the customary leaflet and the thorough initial instruction on how to contract correctly, the training group attended an exercise intervention for a period of 16 weeks (starting eight 8 weeks after delivery). Once a week the training participants attended a supervised exercise class led by an experienced physical therapist. The exercise class protocol is described in detail by Bø et al (1990) and Mørkved and Bø (1997). Additionally, the training group was prescribed to perform daily pelvic floor muscle training at home (three sets of 8-12 close to maximum contractions). Training adherence at home was recorded in a training diary, whereas the physical therapist recorded group session adherence.

SECONDARY outcome

Timeframe: 6 months postpartum (end of intervention)

Population: Primiparous women who delivered a singleton baby vaginally after more than 32 weeks of gestation. They had to have Scandinavian language skills, no severe perineal tearing, no prior abortion or stillbirth after 16 weeks of gestation, and no illnesses interfering with the ability to follow-up.

Urinary incontinence assessed by pad test, as described by Mørkved and Bø (1997). The cutoff value for a positive test was 2 gram. After voiding, the women drank one litre of water. Thirty minutes later they wore a pre-weighted pad and performed a stress test as follows: * Jumping up and down with maximal intensity for 30 seconds. * Jumping with the legs in alternate abduction and adduction (Jumping Jacks) with maximal intensity for another 30 seconds. * Coughing as hard as possible three times. As in the study by Mørkved and Bø (1997), a positive pad-test was set to a cut-off of 2 gram of leakage.
