This group will consist of participants who will be diagnosed with daytime incontinence by a pediatric urologist according to the International Children's Continence Society criteria.

This group will consist of participants who will be diagnosed with nocturnal enuresis by a pediatric urologist according to the International Children's Continence Society criteria.

This group will consist of participants who will be diagnosed with combined daytime incontinence and nocturnal enuresis by a pediatric urologist according to the International Children's Continence Society criteria.

A multimodal pelvic floor rehabilitation program will be performed on all children for 10 weeks, two days a week and approximately 45 minutes. A multimodal pelvic floor rehabilitation will include education, bladder and bowel training, manual techniques, exercise training (diaphragmatic breathing exercise, pelvic floor muscle training, trunk stabilization exercises based on developmental kinesiology) and a home program. The home program will be given on other days of the week.

DVAISS was developed to evaluate the severity of dysfunctional voiding and incontinence symptoms by Akbal et al. DVAISS consists of 14 questions examining daytime and nighttime symptoms, bladder and bowel habits, and quality of life. DVAISS score is based on the estimated odds ratio for each question between participants and controls. If the estimated odds ratio of the question is between 2 and 10, one point is given and if the estimated odds ratio is greater than 50, five points are given. The total score varies between 0 and 35. The increase in the total score indicates that the severity of the symptoms increases. A score of 8.5 or higher on the scale indicates the presence of bladder and bowel dysfunction. The Cronbach Alpha value of the scale was determined as 0.50.

BBDQ was developed to evaluate symptoms of bladder and bowel dysfunction by Afshar et al. The Turkish validity and reliability was conducted by Kaya Narter et al. BBDQ includes 13 questions about bladder and bowel symptoms such as incontinence, voiding, enuresis, dysuria, and constipation. Each question is scored on a 5-point Likert scale ranging from zero to four points. The total score varies between 0 and 52. As the total score increases, symptom severity worsens. A score of 11 points or above is considered bladder and bowel dysfunction. Cronbach Alpha value of the scale was found to be 0.727.

CBBDQ consists of a total of 18 questions that assess bladder and bowel symptoms in children. CBBDQ has two subdimensions: Bladder Symptoms Scale (10 questions) and Bowel Symptoms Scale (8 questions). Considering the presence of children's symptoms in the last month, CBBDQ is filled out by parents on a 5-point Likert scale ranging from zero (no symptoms) to four points (symptoms occur almost every day). The total score from the scale varies between 0 and 72. As the total score increases, symptoms worsen. The Turkish validity and reliability of the scale was conducted by Aydin et al. Cronbach Alpha values were determined as 0.74 and 0.71 for bladder and bowel subdimensions, respectively.

A NeuroTrac MyoPlus 4 PRO (Verity Medical LTD., UK) type EMG device will be used in the study. Bioelectrical activities of the muscles (pelvic floor muscles, abdominal muscles, diaphragm, multifidus) will be recorded with disposable 3.2 x 3.2 cm superficial electrodes. To reduce skin impedance, the skin area will be cleaned with an alcohol swab. Active electrodes will be placed on the right side of the body, parallel to the muscle fibers, according to the reference points. The reference electrode will be placed on the anterior superior iliac spine. Measurements will be performed during five seconds of maximal voluntary contraction ('work' phase EMG activity) and five seconds of relaxation ('rest' phase EMG activity) of the pelvic floor muscles. Measurements will be repeated for three times. The graphic and numerical data provided by the device will be recorded in the evaluation form.
