Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Before starting the research, all participants will be assessed: strength and endurance of the pelvic floor muscles with the help of palpation, EMG and perineometer, bladder diary, UDI-6 and IIQ-7 questionnaire, SES Self-assessment scale, changes in KHQ quality of life indicators and Questionnaire of the Quality of Women's Sexual Life.

Randomized controlled trials will be carried out on a group of not less than 100 patients aged 25-35 years, after the first vaginal delivery or after the first caesarean section, which will be randomly divided into groups:

Arm 1: Vaginal delivery Bebo® group

A group of women after vaginal delivery underwent a 6-week, each session according to the Bebo® concept runs for one hour . The training is conducted individually, by a qualified therapist, twice a week. We will monitor attendance using the attendance list.

The Bebo® concept - is based on five exercise groups, which are: awareness exercises, mobilization exercises, strengthening exercises, relaxation exercises, and the integration of pelvic floor muscles in everyday activities. Each group of exercises will last approximately 10 minutes.

Arm 2: Vaginal delivery Bebo®+ EMG group

A group of women after vaginal delivery underwent a 6-week, each session according to the Bebo® concept runs for one hour , supported by a 10-minute EMG-biofeedback training. The training is conducted individually, by a qualified therapist, twice a week.

The group, apart from exercises according to the Bebo® concept, will perform a 10-minute EMG-biofeedback training. Its aim will be to obtain conscious tension of the pelvic floor muscles with a strength corresponding to 20, 50, 80% of the previously measured maximum contraction and to maintain the tension at the previously indicated level for a preset time: e.g. 3, 5, 10 seconds, as well as muscle relaxation. The contraction time will be determined for each patient individually by the therapist. The biofeedback device will be inserted into the vagina so that participants may modify the tension of the pelvic floor muscles based on feedback from the device.

Arm 3: Cesarean delivery Bebo® group

A group of women after cesarean delivery underwent a 6-week, each session according to the Bebo® concept runs for one hour. The training is conducted individually, by a qualified therapist, twice a week.
Arm 4: Cesarean delivery Bebo® + EMG group

A group of women after cesarean delivery underwent a 6-week, each session according to the Bebo® concept runs for one hour , supported by a 10-minute EMG-biofeedback training. The training is conducted individually, by a qualified therapist, twice a week.

Treatment: Devices
Comparator / control treatment
The active, control group (n = 50), composed of women after the first vaginal delivery or the first caesarean delivery, will be examined twice, 6 weeks apart. Bebo® training and EMG-biofeedback training will not be delivered to participants in the comparator/control group.
Control group
Active

Outcomes
Primary outcome [1] 329553 0
EMG-test. The EMG is used to assess the function of the pelvic floor muscles. The test will be carried out using surface and vaginal electrodes. The first electrode will be placed on the lower abdomen and the second will be mounted on the vaginal probe. The test will be performed according to a protocol consisting of 5 activities:
1.60-second rest (before starting the test - divided into 3 intervals: I-5s, II-5s, III-50s).
2. Five 2-second phase contractions (fast movements), with a 10-second interval in between.
3. Five 10-second tonic contractions, with a 10-second rest in between.
4. One 60-second strength contraction.
5.60-second rest (after exercise).
Timepoint [1] 329553 0
The procedure will be performed at the start of the tests and after 6 weeks.
Primary outcome [2] 329554 0
A perineometer is a device used to measure the resting tension [cmH2O], the maximum voluntary force of contraction [cmH2O] and the strength of the pelvic floor muscles [s]. The examined person places the probe into the vagina to a depth of 3.5 cm. The subject is asked to perform 3 contractions and hold them for 5 seconds, the pause between each contraction was 30 seconds.
Timepoint [2] 329554 0
The procedure will be performed at the start of the tests and after 6 weeks.
Primary outcome [3] 329555 0
Muscle strength assessed by palpation. The examination consists in inserting the index finger into the vagina, after disinfecting the hands, wearing disposable gloves and applying the gel, as well as observing the perineum area. The strength of the pelvic floor muscles during vaginal palpation will be assessed according to the PERFECT scheme.
Timepoint [3] 329555 0
The procedure will be performed at the start of the tests and after 6 weeks.
Secondary outcome [1] 402944 0
Self-assessment of the respondents on the basis of the SES Self-Evaluation Scale by M. Rosenberg. This tool evaluates your self-esteem.
Timepoint [1] 402944 0
The procedure will be performed at the start of the tests and after 6 weeks.
Secondary outcome [2] 402945 0
Quality of life using the King's Health Questionnaire (KHQ questionnaire)
Timepoint [2] 402945 0
The procedure will be performed at the start of the tests and after 6 weeks.
Secondary outcome [3] 402946 0
The quality of sexual life based on the Sexual Quality of Life Questionnaire Female- (SQoL-F)
Timepoint [3] 402946 0
The procedure will be performed at the start of the tests and after 6 weeks.

Timepoint [5] 402948 0
The procedure will be performed at the start of the tests and after 6 weeks.
Secondary outcome [6] 402949 0
Assessment of toilet habits and fluid intake using the bladder diary. The bladder diary was designed specifically for this study.
Timepoint [6] 402949 0
The procedure will be performed at the start of the tests and after 6 weeks.
Each patient will be asked to complete the diary for 3 days at the start of the study and after 6 weeks.
