Obstetric Perineal Trauma and Physiotherapy

The main objective is to investigate effects of perineal trauma at birth on women´s health and whether early physiotherapy improves pelvic floor strength. This will be achieved by an acknowledged/validated questionnaire sent electronically 6 weeks after first delivery. Women with symptomes of urinary incontinence according to the questionnaire will be offered participation in a single-blinded randomized intervention study to compare outcome after targeted physiotherapy with conventional advice and support. Intervention encompasses weekly pelvic floor training for 12 weeks. Pelvic strength will be measured and symptom information collected before and after intervention and 12 months postpartum in both groups.

Pelvic floor problems after delivery are common and often persistent, including urinary/fecal incontinence, pelvic organ prolapse and sexual problems. Such symptoms reduce QoL and handicap women in multiple ways, physically, psychologically and socially. More knowledge of whether interventions and guidelines in this field can improve health and QoL is required.

Single-blind randomized controlled trial (RCT) to assess and compare the effects of early pelvic floor muscle training and present standard care/advice on pelvic floor muscle (PFM) strength, symptoms from the pelvic floor and bothersome symptoms (QoL) after obstetric perineal repair.

Procedure/Study design: Single-blind randomized controlled trial.

Details of test administration and data collection methods:

PFM strength will be measured with Myomed 932® (Enraf-Nonius, Delft, Netherlands) for squeeze pressure, vaginally and rectally.

Pelvic floor symptoms, (bladder/bowel function, prolapse symptoms, sexual function) and bothersomeness will be measured with the validated Icelandic version of the Australian Female Pelvic Floor Questionnaire.

Assessment and treatment will begin from 6th week postpartum. After initial assessment, instruction on pelvic floor function the pelvic floor questionnaire administration, participants will be randomized to intervention and control groups by a person not involved in measurements or treatment. The intervention group will receive individual treatment by a physiotherapist not involved in the initial assesment. This will be in the form of intensive PFMT with vaginal/rectal pressure feedback once a week for 12 weeks and be encouraged to do daily exercises. Repeated assessment of pelvic floor function and questionnaire administration will be after 12 weeks for both groups and repeated 12 months after birth.

Assessment of pelvic floor function includes rectal/vaginal resting pressure, PFM strength (maximal voluntary contraction, strongest of three measured as a vaginal and anal squeeze pressure), and endurance for 10 sec (area under the curve both rectal and vaginal).

Preliminary assumption of power (beta) of 80% and a level of significance (alfa) of 5% and estimating 1 against 3 women with symptoms of urinary incontinence in treatment vs. control groups, respectively after intervention, ca. 40 women will be needed per group.
