The main study is a prospective randomised trial. Women with POP will be referred by selected community gynaecologists working in Oslo and Akershus. Those who express an interest in participating in the project will be referred to physiotherapist and manual therapist Ingeborg Hoff Brækken, who is the project manager. The women will participate in a structured interview; complete a questionnaire about symptoms and quality of life and undergo a clinical examination at. Gynaecologist Majida at Akershus university hospital will conduct the ultrasound examination. The women will be stratified by the stage of prolapse after the pelvic floor prolapse quantifying (POPQ). They will then be randomised into two groups; PFMT or control. Brækken will train the intervention group at Hans & Olaf Fysioterapi A/S. The gynaecologist will be blinded for group allocation. After 6 months all women from both groups will be referred to the physiotherapist where they will complete the same questionnaire about symptoms and quality of life and measure PFM strength. The gynaecologist will then conduct the same ultrasound examination and POPQ.
