Brief Summary

Lower urinary tract dysfunctions (LUTD) are disorders that can occur in the storage and voiding stages of bladder function other than neurological disease or lower urinary tract obstruction. Storage symptoms are increased or decreased voiding frequency, urinary incontinence, urgency and nocturia, while voiding symptoms are classified as hesitation, straining, weak stream and intermittent voiding. Other symptoms are holding maneuvers, feeling of incomplete voiding, post-voiding dripping, genital and lower urinary tract pain. Epidemiological studies show that the prevalence of LUTD is high in school-aged children, with rates as high as 22%. Very little is known about pelvic floor muscle training in children. Relaxation in the pelvic floor muscles is very important for the continuity of micturition and defecation functions. Respiratory function is one of the key elements in the relaxation of the pelvic floor. The relationship of the pelvic floor muscles with the diaphragm and their role in intra-abdominal pressure regulation have been demonstrated by many studies. In the adult population, it has been emphasized that the respiratory pattern should be corrected in pelvic floor dysfunctions and pelvic floor muscle training should be provided in those with respiratory problems. In the literature, rehabilitation programs for children with LUTD are treatment approaches in which respiratory and pelvic floor muscle training are applied together, but it has not been clearly stated which isolated approach is responsible for the resulting effect. In addition, these studies have emphasized that diaphragmatic exercises reduce or improve symptoms through the relaxation mechanism they create in the abdominal wall. However, unlike the literature, one of the aims of this study is to reveal the relationship between inspiratory and expiratory muscle strength and LUTD.

Primary Outcome Measures

Name	Time	Method
Strength of Respiratory Muscle	baseline	To measure respiratory muscle strength, maximal inspiratory pressure (MIP or PImax) and maximal expiratory pressure (MEP or PEmax) measurements will be used with a non-invasive, RP Check brand electronic pressure measuring device.
Level of Physical Activity	baseline	Physical Activity Questionnaire for Children (PAQ-C):The physical activity levels of children will be assessed using the Physical Activity Questionnaire for Children (PAQ-C). The PAQ-C was developed in Canada to evaluate moderate to vigorous physical activity levels. It is based on the child's self-reported recall of the previous 7 days. The PAQ-C consists of 10 items, with 9 items used to calculate the activity score.; The first question includes a list of 22 commonly performed activities. Responses to this question are evaluated on a 5-point scale (1 = never, 5 = 7 times or more). An average score is calculated, with higher scores indicating higher levels of physical activity.

Secondary Outcome Measures

Name	Time	Method
Voiding Disorders	baseline	Voiding Disorders Symptom Score (VOS):The severity of voiding dysfunction symptoms in children will be assessed using the Voiding Dysfunction Symptom Score. This score was developed by Akbal et al. in 2005 and consists of 14 questions in total. Thirteen of the questions evaluate symptoms related to daytime urinary incontinence, nighttime urinary incontinence, daily voiding frequency, the presence of constipation, and various symptoms associated with urinary incontinence. The 14th question assesses the impact of these symptoms on quality of life. The total score of the scale ranges from 0 to 35 points, with higher scores indicating increased severity of voiding dysfunction symptoms.
Bladder and Bowel Dysfunction	baseline	Bladder and Bowel Dysfunction Scale (BDS):The severity of children's bladder and bowel dysfunction symptoms will be assessed with the Bladder and Bowel Dysfunction Scale. The MBDS was developed by Afshar et al. in 2009. Bladder and bowel dysfunction symptoms are assessed and diagnosed with this scale. Its Turkish validity and reliability were made by Kaya Narter et al. in 2017. The scale consists of 14 questions. The first 13 questions are specific to bladder and bowel dysfunction symptoms. The last question questions the degree of difficulty of completing the survey. Each question is a 5-point Likert type and the last question is not added to the scoring. The total score varies between 0-52 and an increase in the score means an increase in symptom severity.
Functions of Pelvic Floor Muscle	baseline	After a brief informative training using visuals about pelvic floor muscles and their functions, the electrical activity of the pelvic floor muscles of children with LUTD will be measured with the 632 Myomed biofeedback device.
