NCT04936464

Brief Summary

This is a single-center, double-blinded, randomized controlled trial evaluating the efficacy of TTNS versus a sham intervention. Both interventions will be performed by participants in their homes after standardized instruction. The primary outcome is a comparison of the mean change in OAB-q scores before and after treatment between the intervention and control groups. Changes in the number of urgency incontinence episodes and an estimation of cost effectiveness will additionally be measured. Intention to treat analysis will be performed.

Outcome Measures

Primary Outcomes (1)

  • Overactive Bladder Questionnaire (OAB-q)

    To evaluate the efficacy of a 12-week course of TTNS in reducing urgency urinary incontinence (UUI) symptom bother in the intervention versus sham group.

    12 weeks

Secondary Outcomes (1)

  • Voiding diary

    12 weeks

Other Outcomes (1)

  • Incremental cost-effectiveness ratio (ICER)

    12 weeks

Study Arms (2)

Intervention Group

EXPERIMENTAL

30-minute treatments, twice weekly x12 weeks

Device: transcutaneous tibial nerve stimulation (TTNS)

Sham Group

SHAM COMPARATOR

30-minute treatments, twice weekly x12 weeks

Device: transcutaneous electrical stimulation (TENS)

Interventions

TTNS is a non-invasive, surface electrode therapeutic stimulation technique available for home administration that has been proposed as a treatment for overactive bladder.

Intervention Group

The sham intervention is designed to appear almost identical to the TTNS intervention.
