NCT05989646

Brief Summary

The aim of this study is to investigate whether the activity in brain areas controlling the bladder is different among children suffering from Overactive Bladder (OAB) and Daytime Urinary Incontinence (DUI) compared to age- and gender-matched healthy children without bladder symptoms. Moreover, the aim is to investigate if sacral transcutaneous electric nerve stimulation (TENS) has a central mechanism of action. Children with OAB and DUI will be recruited from involved pediatric departments, and functional magnetic resonance imaging (fMRI) will be performed before and after 10 weeks of sacral TENS. In healthy children without bladder symptoms, only the baseline fMRI will be performed.

Outcome Measures

Primary Outcomes (2)

  • Activity in brain areas controlling the bladder

    Blood Oxygen Level Dependent (BOLD)-signals on functional MRIs, compared between children with Overactive Bladder and Daytime Urinary Incontinence and children without bladder symptoms.

    Baseline

  • Change in activity in brain areas controlling the bladder after TENS-treatment

    Blood Oxygen Level Dependent (BOLD)-signals on functional MRIs, compared between responders and non-responders to TENS-treatment.

    Baseline AND immediately after the intervention

Secondary Outcomes (10)

  • Structural differences on MRI among children with OAB and DUI and healthy children

    Baseline

  • Differences in Quality of Life (QoL) between children with OAB and DUI and healthy children

    Baseline

  • Change in WHO-5 score among children with OAB and DUI at baseline and after the intervention.

    Baseline AND immediately after the intervention

  • Change in PinQ score among children with OAB and DUI at baseline and after the intervention.

    Baseline AND immediately after the intervention

  • Change in WHO-5 score among children with OAB and DUI compared among responders and non-responders to sacral TENS treatment.

    Immediately after the intervention
