The participants assigned to this group will receive 16 sessions of physical therapy. Each session will last 45/50 minutes, 2 sessions a week for 8 weeks.

A directly pelvic floor muscle(PFM) training protocol will be applied. Throw vaginal palpation and in lithotomy position, participants will perform PFM exercises per the treatment proposed by the PERFECT scheme. Biofeedback exercises will be also performed in lithotomy position. Hypopressive exercises which are also home daily from the eighth session. Plus educational strategy.

Only educational strategy 1 session per week for 6 weeks (every session will last 40/45 minutes). The educational strategy will consist of instruction of printed materials and dimensional anatomical models about the anatomy of the pelvic floor and the physiology of the pelvic organs. It will be recommended to avoid risk factors, such as gaining weight, weight lifting, high impact sports, constipation, smoking, or drinking too much caffeine. They will be also instructed in toilet habits, and will be taught to use the knack maneuver before and during increases of intra-abdominal pressure.

The PFIQ-7 consists of 3 scales of 7 questions each taken from the Urinary Impact Questionnaire, the Pelvic Organ Prolapse Impact Questionnaire, and the Colorectal-Anal Impact Questionnaire. The 3 scales are scored from 0 (least impact) to 100 (greatest impact) and an overall summary score (0 to 300).

P-QOL assess the symptom severity and its impact on the quality of life in women with POP; and the PFDI-20 that is both a symptom inventory and a measure of the degree of bother and distress (QoL) caused by pelvic floor symptoms. The PFDI-20 includes 20 questions and 3 scales. Each of the 3 scales is scored from 0 (least distress) to 100 (greatest distress). The sum of the scores of these 3 scales serves as the overall summary score of the PFDI-20 and ranges from 0 - 300 and the higher the score, the worse QoL. The 3 scales include questions taken from the following widely used outcome measures: Urinary Distress Inventory - 6 questions, Pelvic Organ Prolapse Distress Inventory - 6 questions, and Colorectal-Anal Distress Inventory - 8 questions collecting data about UI, POP and colorectal and anal symptoms.

Three maximum PFM contractions will be requested and will be used the mean value. For the manometry (cm2O2), an air-filled probe will be used ("Peritron", Melbourne, Australia)
