Currently, guidelines from the Royal College of Obstetricians and Gynaecologists stipulate that all women who have sustained an obstetric anal sphincter injury in a previous pregnancy and who are symptomatic or have abnormal endoanal ultrasonography and/ or manometry should be counselled regarding the option of an elective Caesarean section. An abnormal endoanal ultrasonography is currently considered to be a defect of the external anal sphincter (EAS) of more than 30 degrees while an abnormal anorectal manometry would be an incremental squeeze pressure of less than 20mmHg.
This study aims to evaluate if a course of guided pelvic floor exercises could improve anal sphincter function on those with suboptimal or abnormal anal incremental squeeze pressures, and subsequently expand their options for future modes of delivery (vaginal delivery not contraindicated)
