简要总结
The purpose of this study is to assess the efficacy of additional neuromodulation for treatment of chronic constipation in pediatric patients
详细描述
Patients are selected according to the eligibility requirements. After being informed about the study and potential risks of neuromodulation, all included patients and next of kin give written informed consent to the study.
At baseline, patients are classified to one of the two predefined subgroups: either medical and behavioral therapy is extended and optimized or neuromodulatory treatment is started with non-invasive sacral nerve stimulation via single current and two external adhesive electrodes. Within 12 weeks, treatment success is evaluated in routine clinical check-ups (week 4/8/12) and via specialized questionnaires and bowel movement diaries. Quality of life is evaluated at baseline and after 12 weeks of treatment.

结局指标
主要结局
Symptoms: Change in defecation frequency
时间窗: Baseline and 12 weeks after start of therapy
Defecation frequency is measured by bowel movements per week.
Symptoms: Change in defecation consistency
时间窗: Baseline and 12 weeks after start of therapy
Defecation consistency is measured by the Bristol Stool Scale, which classifies stool consistency from 1 (hard consistency) to 7 (fluid consistency).
Change in Quality of Life
时间窗: Baseline and 12 weeks after start of therapy
The quality of life is classified via the 'Revised Children's Quality of Life Questionnaire' (KINDLR). It consists of 24 5-point Likert-scale items, covering 6 quality of life dimensions: physical well-being, emotional well-being, self-esteem, family, friends and daily functioning (school or nursery school/kindergarten). Items are partially reverse scored and linearly transformed to a 0 to 100 scale according to the manual. Higher scores indicate a better quality of life.
Symptoms: Change of encopresis/soiling
时间窗: Baseline and 12 weeks after start of therapy
Episodes of encopresis/soiling are evaluated per day.
次要结局
- Symptoms: Change of abdominal pain(Baseline and 12 weeks after start of therapy)
