Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The transcutaneous electrical stimulation (TES) machine is a small device (approximately 20 cm x 30 cm), connected to 240V power source. It has two independent channels of current. We use electrodes that are small sticky pads of 4 cm x 4 cm (pure silicon). The device delivers an interferential current with a carrier frequency of 4 Hz, a beat frequency sweep covering 80 to 160 Hz, with an adjustable intensity less than 33 milliA. Individual pulses have duration of 250 micros (constant alternating current).
Two pairs of electrodes are placed on the front and on the back of the inferior abdomen. Stimulation will be delivered daily for 1 hour, either mornings or evenings, for 2 months, at home, by the participant themselves or their carer.
Patients will be in contact by phone each week and asked if they have used the TES each day and for how long. TES use will be recorded on the daily bowel diary.

Comparator / control treatment

Control group
Uncontrolled

Outcomes
Primary outcome [1] 292893 0
Severity of faecal incontinence (based on the bowel diaries). The bowel diaries will record frequency of bowel movements, time spent for defecation, need for help for evacuation (digital stimulation, laxatives, enemas), feeling of completeness of evacuation, associated pain, frequency of faecal incontinence, incontinence for solid or liquid stool, incontinence for gas, need to wear a pad or a plug. It is a composite primary outcome: this will allow us to obtain a score of faecal incontinence (St-Marks faecal incontinence score).
Timepoint [1] 292893 0
Daily diaries will be completed by the participant during a two times two-week period, during the 2 months of baseline measurements and then during the 2 months of the intervention (stimulation), .
Secondary outcome [1] 309880 0
Quality of life (assessed by the FICQOL questionnaire)
Timepoint [1] 309880 0
Before intervention (baseline) and on completion of the 2-month intervention period
Secondary outcome [2] 309881 0
Colonic transit time (evaluation by radiopaque markers)
Timepoint [2] 309881 0
Before intervention and on completion of the 2-month intervention period

Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Faecal incontinence in children with spina bifida is currently treated by retrograde continence enema. Transcutaneous electrical therapy will be proposed as an alternative therapy to children with spina bifida aged 8-18 who have failed retrograde continence enema treatment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Type of endpoint/s
Safety/efficacy
Statistical methods / analysis
This phase II study will provide data about the distribution of the incontinence frequency in the population of children with spina bifida who failed treatment with retrograde continence enema. The population is foreseen to be heterogeneous.
We will compare the severity of faecal incontinence and the quality of life before and at the end of 2 months of transcutaneous electrical stimulation. After this study, the range of confidence intervals could be estimated.
