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.
