The sample of the study will consist of children between the ages of 6-15 years who were admitted to Malatya Inönü University Turgut Özal Medical Center Pediatric Urodynamics/Urotherapy Unit and diagnosed with LUTD by a pediatric nephrology specialist. Inclusion criteria: Being between the ages of 6-15 years, having a normal neurologic examination, being diagnosed with LUTD, having a DVISS of 8.5 and above, not having received any medication or other treatment for enuresis before. Exclusion criteria were as follows: patients with primary nocturnal enuresis, patients with uncontrolled systemic disease, patients with neurologic disease (muscle disease, epilepsy, etc.), patients with inflammation of the vagina, anus and urinary tract, patients with febrile illness or active urinary tract infection, presence of underlying psychological causes, presence of mental retardation, inability to comply with treatment. Children who meet the inclusion criteria will be included in the study by non-probability random sampling method. The inclusion of the three clusters formed according to the registration number of the Pediatric Urodynamics/Urotherapy Unit will be determined by lottery method. After the children and their parents/guardians who meet the inclusion criteria are informed about the study content, they will be asked to sign the informed consent forms for the child and the informed consent forms for the parents/guardians if they agree to participate in the study.

The individuals participating in the study will be divided into 3 groups. Children in Group I will exercise according to DNS principles 3 days a week for 12 weeks, with sessions of 45 minutes. Children in Group II will receive animated EMG biofeedback training with the Aymed Medikal Locum Wireless System v.2.69.0.12 device. For animated biofeedback application, two electrodes will be placed at 3 and 9 o'clock in the perineum region and 1 reference electrode will be placed on the inner side of the thigh (42). The training protocol will be applied once a week for a total of 12 sessions for 3 months. In addition to exercises with the DNS principle 3 days a week, the children in Group III will receive biofeedback training with animation once a week with the Aymed Medikal Locum Wireless System v.2.69.0.12 device for a total of 3 months. Demographic data of the individuals participating in the study will be obtained through a questionnaire from each child participating in the study. The questions in the questionnaire are personal information of the child, toilet training age, frequency of urinary tract infections, whether they have received treatment for urinary incontinence before, whether they have chronic constipation, whether their parents have a history of urinary incontinence at a young age and some personal information specific to the parents.

The Dysfunctional Voiding and Incontinence Scoring System (DVISS) will be used for symptoms of voiding dysfunction and urinary incontinence. The DVISS is a 13-item questionnaire. It originally includes 14 questions about symptoms and 1 question about quality of life. In the scoring system developed by Akbal et al. for the pediatric population and adapted to Turkish, there are 13 symptom and 1 quality of life question.

Evaluation of uroflowmeter parameters will be performed with the uroflowmeter application of the Aymed Medikal Locum Wireless System v.2.69.0.12 EMG device and the urine flow curve and voiding parameters of the patients will be evaluated. These parameters are maximum flow rate, time to reach maximum flow, mean flow rate, voiding volume and voiding time. In our study, urine volume of 100 ml or more will be considered valid. Evaluation of deep trunk muscles (transversus abdominis, multifidus and deep neck flexors) will be performed with the Stabilizer Pressure Biofeedback Unit (Chattanooga Stabilizer, USA). Before the test, each participant will be taught how to contract the transversus abdominis muscle with the corset method in the supine and quadripedal position and how to contract the multifidus muscle in the supine position. Measurements will be made for 10 seconds and 3 repetitions, three measurements will be recorded and averaged. For the measurement of the deep neck flexors, the patients will first be taught the correct craniocervical flexion movement without activation of the superficial muscles. The change in pressure will be recorded and the highest value from 3 trials will be taken. Individuals will be evaluated before treatment, at 4 weeks, 8 weeks and 12 weeks after treatment. The aim here is to measure how long it takes to show the effectiveness of the treatment(s) applied and to determine whether the treatments are superior in terms of time.
