Objectives: To analyze the Mode M ultrasound use in the assessment of pelvic floor musculature (PFM) and in the rehabilitation of motor control in pelviperineal dysfunctions that affect the support of pelvic organs, urinary and fecal continence and reproductive and sexual functions. Methodology: A cross-sectional descriptive study will be followed by a randomized clinical trial. There will be two samples: a sample of volunteers without PFM dysfunction; and a sample of patients with pelviperineal dysfunction derived from health centers in the Region of Murcia. An intra- and interobserver reliability study of transabdominal M-mode ultrasound of PFM will be performed. Then, a cross-sectional descriptive study of the functional behavior of PFM will be used in different functional situations such as: voluntary contraction at maximum force, fast contraction, Valsalva maneuver and forced cough. The following ultrasound variables will be measured: direction and amount of displacement, speed of displacement and time of contraction. Correlations between ultrasound variables and sociodemographic and clinical variables will be analyzed. The randomized clinical trial will compare a PFM contraction awareness treatment based on endocavitary digital contact with a motor learning program based on transabdominal mode M ultrasound biofeedback.

Changes in the self efficacy expectations in performing pelvic floor exercises.
It will be assessed by the Broome Pelvic Muscle Self-Efficacy Scale (PMSES) Spanish version. Self-efficacy expectations, specifically for performing pelvic floor exercises, are measured with 14 items with responses between 0 and 100. One hundred represents high level of confidence.
Time frame: At baseline and after the intervention (1 week from baseline)
Changes in the outcome expectations for pelvic-floor exercise treatment.
It will be assessed by the Broome Pelvic Muscle Self-Efficacy Scale (PMSES) Spanish version. Outcome expectations are measured with 9 items with responses between 0 and 100. One hundred represents high level of confidence.
Time frame: At baseline and after the intervention (1 week from baseline)
Change in the displacement of the base of the bladder during voluntary contraction of the pelvic floor.
It will be measured by Ultrasonography.
Time frame: At baseline and after the intervention (1 hour from baseline)
