Outcome Measures

Primary Outcomes (4)

  • Symptoms: Change in defecation frequency

    Defecation frequency is measured by bowel movements per week.

    Baseline and 12 weeks after start of therapy

  • Symptoms: Change in defecation consistency

    Defecation consistency is measured by the Bristol Stool Scale, which classifies stool consistency from 1 (hard consistency) to 7 (fluid consistency).

    Baseline and 12 weeks after start of therapy

  • Symptoms: Change of encopresis/soiling

    Episodes of encopresis/soiling are evaluated per day.

    Baseline and 12 weeks after start of therapy

  • Change in Quality of Life

    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.

    Baseline and 12 weeks after start of therapy

Secondary Outcomes (1)

  • Symptoms: Change of abdominal pain

    Baseline and 12 weeks after start of therapy

Study Arms (2)

Non-invasive Neuromodulation

ACTIVE COMPARATOR

Application of non-invasive sacral nerve stimulation for 12 weeks, at least 8 hours per day. Two adhesive electrodes are placed paravertebrally between L1 and L4 and periumbilically, generating an electrical field with a 15 Hz frequency for a duration of 210µs. Stimulation intensity is individually determined to achieve an effective and comfortable stimulation beyond the pain threshold (adjustable amplitude between 0-10mA). Medical and behavioral therapy is to be continued as started before intervention.

Device: Non-invasive Neuromodulation

Medical/behavioral Therapy

OTHER

Patients receive an optimized conventional treatment for 12 weeks, including lifestyle changes, toilet training and weight-adjusted medication. Conventional medical options include oral laxative medication with polyethyleneglycol or rectal medication with saline enemas in possible combination with a stimulant laxative (glycerin or bisacodyl).

Other: Medical and Behavioral Therapy

Interventions

Sacral nerve stimulation via two adhesive electrodes (single current).

Non-invasive Neuromodulation

Behavioral Therapy consists of toilet training, an active and healthy lifestyle. Doses of medical options are applied weight-adjusted.

Eligibility Criteria

Age2 Years - 17 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • age between 2-17 years
  • informed consent
  • chronic constipation according to the ROME IV criteria for more than 3 months with or without encopresis/soiling
  • refractory to conventional treatment in a sufficient application (training for bowel movements, lifestyle changes, pelvic floor training)
  • in cases of underlying Hirschsprung's disease: confirmation of diagnosis via rectal biopsies
  • in cases of anorectal malformation: post-surgical status

You may not qualify if:

  • metabolic, inflammatory and hormonal causes for chronic constipation with further therapeutic options
  • toxic megacolon or further emergencies, which must be treated surgically
  • fractures or substantial differences in the sacral anatomy
  • inflammatory bowel disorders
  • rectal prolapse
  • neuronal malignancies under medical and radiation therapy
  • seizures
