Brief Summary:

Part I of the TaPaS trial forms part of a twofold clinical RCT:

Part 1) A prospective RCT comparing the efficacy of transcutaneous tibial nerve stimulation (TTNS) with TTNS sham therapy for children with idiopathic overactive bladder on clinical and patient reported outcomes (PROMS).

Part 2) A prospective RCT comparing TTNS versus Percutaneous tibial nerve stimulation (PTNS) on clinical outcomes and PROMS.


Condition or disease Intervention/treatment Phase
Overactive Bladder Syndrome Device: TTNS Device: TTNS Sham Not Applicable

Detailed Description:

Non invasive neuromodulation therapy for children with the overactive bladder syndrome is a highly under investigated topic in medical literature.

Only 2 studies ( Patidar et al. and Boudaouid et al.) investigated the use of tibial nerve stimulation with adhesive electrodes.

1) In the first trial the superiority of TTNS vs.Sham therapy for the therapeutic management of children with OAB naive to any pharmacological treatment will be examined.

Clinical outcomes will be assessed by the use of daytime and nighttime bladder diaries.

Assessment of outcomes at baseline, after 6 weeks and 12 weeks of treatment, and investigation of mean time to partial or complete relapse following 6 weeks observation.

After a wash-out period of 6 weeks, patients from the part I Sham group will be able to be included for TaPaS part II.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 6 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:

Prospective randomized-controlled superiority trial:

TTNS(Active treatment) vs. Sham TTNS (placebo)
Masking: Double (Participant, Outcomes Assessor)
Masking Description:

Participants are blinded for the given treatment ( Active TTNS vs. Sham TTNS) by the care provider ( Physiotherapist).

The outcomes assessor (the pediatric urologist) isn't aware of the treatment neither.

Arm Intervention/treatment
Active Comparator: Active TTNS
Children treated by transcutaneous tibial nerve stimulation. TENS device connected to adhesive electrodes. Stimulation settings: 200 µS, 20 Hz, 1-20 V ( depending of sensory response) Home-therapy: Daily stimulation during 60 minutes.
 Device: TTNS
See section 'arms' Stimulation settings: 200 µS, 20 Hz, 1-20 V ( depending of sensory response) Home-therapy: Daily stimulation during 60 minutes.
Other Name: Transcutaneous tibial nerve stimulation
Sham Comparator: TTNS sham intervention

Children treated by TTNS with same positioning as the active TTNS treatment. Stimulation settings: 200 µS, 20 Hz, 0-1 V. Patients and parents will be told that electric currence is given, but that no sensation will be feld.

Home therapy: Daily stimulation during 60 minutes.

 Device: TTNS Sham
See section 'arms'
Other Name: Sham therapy

Primary Outcome Measures :
  1. Mean voided volume per void [ Time Frame: 12 weeks ]
    Difference in mean voided volume per void in percentage


Secondary Outcome Measures :
  1. Maximum voided volume (ml) [ Time Frame: 12 weeks ]
    Maximal voided volume per void ( ml) .

  2. Number of urgency incontinence episodes / 24 h. [ Time Frame: 12 weeks ]
    Reduction in number of incontinence episodes per 24 hour

  3. Daytime voiding frequency [ Time Frame: 12 weeks ]
    Mean voiding frequency per day

  4. Satisfaction on urinary symptoms reported by parents [ Time Frame: 12 weeks ]
    Subjective satisfaction reported by the parents - on a 7 point likert scale- "How satisfied of dissatisfied would you be if the bladder symptoms of your child would persist like this?

  5. Time to recurrence [ Time Frame: At 12 weeks of treatment + at 6 weeks of observational period without treatment. ]
    Time to complete or partial relapse to baseline symptoms after 12 weeks of treatment during the observational period of 6 weeks.
